A few mo. back I did find someone that sounded to me as a very knowledgeable person. He was leery of tuning my car because he was not familiar with MegaSquirt. I offered to send him the link to Megatune software so he could mess with it on his own time but it would probably be an expensive proposition for me regardless.

My Miata is non aspirated and I'm trying very hard not to sacrifice driveability for the gains from using a stand alone ECU so I agree about the tip in etc.

I have also considered driving the little bugger to DIY but I have no clue what they charge and I'm not looking forward to an over 8 hr drive.

I would not let someone tune my car if they were not familiar with the software unless they were going to commit to a written agreement that included all aspects of the tuning I wanted and a fixed price. I'm not going to pay someone $500 because they are incompetent when a competent tuner may only cost $300 because of how fast they can do everything.

Jerry charges $125/ hr I suspect a full tune by them would take 2-3 hrs. I don;t think they would assume that anything you have done is correct. I think they would start from the beginning.

Maybe later on when I gather some funds ;)

I need to get v990.4 installed, I tried using it but had the issue with it giving up after the first use. Then I had other issues with MSII so I threw my MSI back in...I'll give it more use the remained of the week.

Hey, I have the "regular" Tuner Studio ... If I click update when it propmts me, do I need to reinstall the firm ware and all that ?

Thanks

Just for those that are afraid to adopt, this is the WOT fuel curve that it ended up leaving me with after today. The dips at the beginning and the end are due to accel/decel settings being off.

i'm setting this up now -- i copied my airdenfactor, thermfactor, and edited my lambdasensors file (my AEM uego never worked right at 9.72 + ... for hte formula, i needed 9.0 + ... )

Anything else I need to set? I know for MT you need to set up which MS you have, what kind of WB, etc.. where does all that go?

EDIT: Nevermind... For all TS newbies, just go to "File" -> "New Project", it walks you through the settings.

@Jeff_Ciesielski -- that's nice! can't wait.

What about if you are going from the old version to the new version ?

Is your LC-1 set to "instant" display? Even my Logworks is noisy, I'm sad.

I'm 99% sure my LC-1 is set to instant display. I had it changed at one point but I'm fairly sure I changed it back. In order to get it that clean I had to run the signal wire back behind the passenger seat and then along the door sill to my harness. there is just too much BS going on in the center console for me to get a clean signal.

Jeff, You really gotta teach me the ways of tuning using TS.

One last question for you Jeff (sorry for hijacking), but what is your zoom set to in that log?

I think you, Brett, and I need to get together and just have a tuning day. I'll just save a backup tune and fuck my stuff up intentionally. That way we can go through and fix it step by step.

That is zoomed all the way in.

Can we do some detonation too?

Indeed we can. It's on my list of stuff to do next weekend.

You will need to update your inc files if you made changes to them. Updating to the new version will overwrite them.

I keep a copy of my modified ini files in another folder so that I can just copy and paste them after an update.

ctxspy: Are you using the controller or gauge type AEM? If it's the controller type I modified my ms2 ini file to accomodate the 230x controller type aem WB. It works great.

Just rename the file MS2ReferenceTables.ini and put in the tunerstudio inc folder

If I connect to the ECU and click on "Detect" do I still need to copy those files or does that only get me the ECU type etc ?

For some reason I had a lot of trouble getting the files saved in the right place :vash:


Thanks :wavey:

Detect only looks for the firmware file

Thanks !!! I'll try it but I'm not looking forward to it :drool:

Having used the autotune for a day i can say i like it... I initially forgot to edit a formula in the ini file so it was seeing AFRs incorrectly in the target table, but after that was resolved it appears that the live tuning works quite well.

i'm goign to let it do its thing for around an hour's worth of driving and save the map it ends up with. I will then re-set to the previous MSQ and do it over again. Then I can see if the results are the same (they should be.. right??)

-Tomaj

what problems do you experienced.?
I'm about to modify the board to change to MS2

Anyone know what happens if you change settings while it's auto-tuning? Like today I changed from "easy" to "normal". Do I need to start and stop the auto-tuning for the change to take effect?

I've been playing some more with this feature. Over the past couple of days I've run the autotune feature about 5 times. It seems to tune within two fuel points around a certain value. I presume this has to to with the difference in temp. My 3D view isn't really very smooth, but my car runs very smoothly. This is probably due to the MS2's ability to interpolate between cells very quickly and efficiently.

My accel enrich is turned off, and so is my EGO correction.

Do you guys have accel enrich set to MAP or TPS based?

I have some nice long steep hills in the area so I am going to try to autotuning on these this weekend.

Is everyone else manually smoothing their ve table, or are you all letting it be, and then letting the EGO correction do its thing?

How many of you are tuning with EGO and accel enrich on, and how many with them off? How many have autotuned in both scenarios? Which did you think worked best?

I always tune with EGO and accel enrichments on. It's pretty apparent where you'll nee dot tweak things, shit should be close after a week of driving around, eventually it'll just wanna move the numbers up or down a point or two depending on the current conditions and it's nothing EGO wont take care of anyways.

I went to buy a power inverter at lunch today, not only did they not have the one the website said was in stock, but i broke my damn usb port on my laptop!

I autotune with everything left on. What I've noticed is that autotune produces a VE table that doesn't look anything like what I would produce by hand. It is a little choppy which makes me want to hand smooth, but I have to say, the car runs great and my logged afr's are dead on, so I'm not sure if its worth my time.

HELP! On the way home today I turned on the EGO correction for the first time. It made my car run like ass. I know that I can get quality results from my WBo2 because the VE live works like a charm. VE live made my car feel super smooth. I also turned on accel enrich with lag compensation. It didn't seem to do anything.

What is everyone using for EGO settings. I must not have it sampling for long enough or something.

Can you post screencaps of your accel enrich and ego settings. I am planning on running diyautotune defaults. I'll give autotuning a try with these turned on.

So here is what my settings currently are for the ego and what I'm changing them to after reading the documentation on msextra.com:

Ignition events per step 16 -----> 29
Controller authority 10 ----> 5
above coolant 160 -----> 177.1
above rpm 1300 ----> 1200
Below tps % 70 ----> 70
Active below map 90 ---- 100
Active above map 20 ----> 20

WB controller settings PID

What are these settings?

Also, can someone who has very stable afr's post a screen cap of their ve live session. I want to see how my oscillations compare with someone that has a nice stable signal.

Thanks for posting the settings.

Have your EGO set to 700rpm imo. That way it trims at idle too. All idle cells the same value and set ignition events to 24 cycles so it reacts quickly.

I don't like it touching idle personally.

I just need to rescale my idle columns right now, I'm at 500, 800, 1000, 1500, I hardly touch the 500 rpm row obviously, but I need an extra column between 1000 and 1500 so I need to fool with them to help out my idle.

(I'm working with a brand new 16x16 ve fuel table :) )

I can't see any reason not too apart from having solid afrs ;)
I've heard lots of people saying they don't like EGO corrections at idle, but I've never heard a reason why.

Here's why I choose to have EGO correct from 700rpm up and shut off at 85kpa.
Oh and I need more injector...:giggle:

I could give it a try, its been like 4 years since I've tried it at idle.

here's my typical idle:

i like having ego correct my idle for summertime heaksoak, other than that i don't see a need for it if you have a solid ve map

Here is my afr at idle. Center graph i red. 2x zoom

Where do you have your wideband grounded? I have mine grounded to the cars chassis ground and the ecu ground on the head. Does anyone use the MS ground? I was thinking about using one of my diypnp grounds and the chassis ground.

I have mine grounded within my boomslang harness which is pulling it off the MS grounds, which grounds through the factory wiring to the fuel rail.

My LC-1 grounds (3 of them!) are wired as per the instructions.

Signal and analog grounds (GREEN and WHITE) are together and soldered at the stock ECU (Im running parallel)
The noisey heater ground (BLUE) is running to the engine earth strap at the back of the head.

are you sure?

This thread inspired me to rig up this little gem so I could run >20 minutes and play around with TS. The inverter is one of the ones from Harbor Fright. $30, works great, although the built-in fan is a bit loud.

Attachment 201080

What I found interesting is that I get the occasional comm reset in Megatune, presumably due to a noisy CAS signal, but running the real-time traces in TS I never saw any of the characteristic blips/spikes in rpm or AFR. I think I had selected a 15 Hz refresh for TS and I'm pretty sure MT runs a faster sampling rate, maybe that has something to do with it? I still haven't played with the tooth/sync logging.

I still need to play around with the software a bit more before I allow VE analyzer to autotune it, but it looks promising. Running the latest updated version all my settings appear to stick like they should. The ability to set maximum cell changes is great, something that would have saved me a bunch of manual editing with the old MLV.

For those of you using the ground on the passenger side of the head as I do -keep in mind that the ground is a bracket that itself bolts to the side of the head. So you could well have corrosion and resistance at the bracket to cylinder head junction and result in ground loops.

The best approach in my opinion is to have as many of the grounds as possible physically tied together such as soldering them to the same lug.

I had a lot of problem with comm. drop outs, re sets and whatever you call it using MT. I tried several different adapters etc.
These problems occurred when powering the lap top from a converter feeding off the 12v vehicle source or lap top battery or lap top wall wart powered from the garage AC. Most of my MSQ were corrupted as a result of this :vash:
The issue has all but disappeared since using TS. :dunno:

Haha. my inverter, that is mounted behind the passenger seat hes the cables routed into the trunk and to the batt thats in the car. Thats dangerous to have in the car with you if something happens.

Obviously I'm not taking any high speed turns with the battery sitting unsecured like that. I rigged it up around midnight just to quickly try TS on some mostly deserted roads. I have a cigarette plug power adapter on the way so I'll see how that works. If it sucks I may end up doing a more proper hardwired installation of the inverter. This pimpin' live VE analyzer function has finally inspired me to do something about my laptop power situation.

Hi Guys, appreciate a little advice. I am using the new auto tune program and think its really good, it has improved my fuel map no end. But I dont know if I have everything set up right to get the best from it, I have tried to follow the thread on here but alot of the terminology is confusing as I am quite new to MS.

I have left all setting stock on the autotune tab except the authority limits which are set to 15 and 20. I note some of you have changed your EGO settings, Mine are standard as follows:

Switch Point - 1.882
Ign Events - 72
Step size(%) - 1
Authority - 10
Above coolant - 71
above rmp - 1000
EGO correction step counter - Ing Pulses
Should I change these? or anything else in TS?

My set up is:
1.6
M45
LC-1 wb o2
MS1 v3

Very grateful for any advice as I am on a steep learning curve!!
Cheers,
Barry

For the EGO stuff you will learn a good bit by searching this MS subforum for "EGO correction" or similar terms, or reading the Megamanual, to learn what all the various parameters do.

But real quick, your switch point is most likely wrong considering how most people have configured the output of their LC-1. You want that to be the voltage it outputs at stoich (14.7:1). If the LC-1 is set up for 0-5V = 10-20:1 then it should be 2.35V. If you have the LC-1 configured for 0-5V = 0.5-1.5 lambda, then it should be 2.50V.

Most people activate it at a higher coolant temp. I think mine is at 140. Not super critical but you probably don't need EGO correction during warmup. The rest of your EGO settings are fine but you should read up and learn what they do anyway. Note that EGO settings are stored in your Megasquirt and it will do closed loop correction without being hooked to a laptop running TS. You can use TS as an interface to adjust them, but I wouldn't call them "TS settings" per se. Also, EGO correction uses your VE table as a base from which to adjust fueling, whereas VE analyzer live will change the actual values in the VE table. The way you lumped your questions together like that, it wasn't clear whether you understood the difference. :noob:

For the VE analyzer authority limits, my fuel map is pretty good by now so I'm going to run a max cell change of 5 and a max % of 10, with the drop-down tab set on "very hard." Yeah baby, very hard. :giggle: If your tune is more rough, you can set it on "easy" or "normal" and/or give it more authority as necessary.

Many thanks for that, its starting to make sense and I will read up as you suggest. I am positive my LC-1 is configured for 0-5V = 0.5-1.5 lambda, so I will change the switch point to 2.50v. Appreciate your help bud.
Barry

Where in TS do you guys configure for wideband type ?

It is not like MT ! :noob:

File -> project options IIRC

Omg. I finally started using TS today because of this. Tuning live made my eyes well up a little bit. I might even try and put my boost controller back in and turn it back up to 12psi.

I had been ignoring my megasquirt stuff for a long time because I was just so sick of opening megatune. I'm now finding myself playing with lots of settings that have been in need of adjustment for months.

Oh man its a good day.

well. I might try my PID closed loop boost control today SO HA!!!!!!!!!!!!!!!!!!!

How are you getting on with PID idle Braineack?

I can get it it Idle steadily untill I turn the lights on whereupon it's oscilate until I intervene and then it'll be steady again.

Close but not good enough!

I'm not. I'm letting the OEM ecu handle it. Lollerskates!

Got it . thanks ! :bigtu:

I'm having an issue with this as well. Idles fine until lights come on. Then it hangs on at about 500 rpm. MSextra.com has a set of tuning instructions for closed loop idle under the MS3 documentation. I was hoping that someone more savvy than me had figured it out already.

To the book apart from that noisy heater ground then. ;) I can't see how the ground for the heater element of the sensor will cause a potential offset in AFRs.

Signal, analog and MS are all at the stock ECU. Perhaps during warmer, lighter days I will rig up a proper grounding strap and run directly to the head.

What are you guys using for your PID EGO settings? I can't find any recommended settings on msextra.com.

I'm going to try the recommended closed loop idle settings recommended in the MS3 section.

I'll report back

Last time I messed with EGO I enabled some authority (not with PID control) and feck all happened, I have an EGO correction guage and it never budged.

Not had chance to mess with it since, please report back how you get on!

I like being able to log your AFR targets for MLV in MSII

I installed a light weight flywheel before the MS.

If I go turbo I'll go and install a better clutch and the fw will come off.
