I do, it gives a damn near perfect afr during WOT and its pretty smooth on the ramp up to full boost.

TS reads the AEM WB perfectly without having to fool around with the .ini files. Functionallt the programs are identical, just load in your map and you should be fine. Any errors will show up on the log and will be stupid things like volts mismatch or something that wont effect your tune/settings.


AFR Targets only get logged in MS-II; I'm pro like that.

You can add a custom field in MLV to do similar with a MS1 though...

CRAIGO

Would you be so kind as to offer the instructions on how to get this custom field? I'd find it handy to go over what autotune has been doing over the course of say an hours drive and see if the traces start to sync up more and more.

Sounds awesome and I want in.

Ok I won't mess with them. It seems that my MLV and MT AFR reading is 0.6 AFR leaner than what my AEM gauge reads. I take that this is not normal? Just wondered if this was a wiring/voltage difference issue. Which one do you believe?

I also would be interested in the custom gauge suggested richyvrlimited!

Sorry I'm such a

Thanks!

mine is also doing the same, the support for the aem gauge wideband is poor at best in both megatune and tunerstudio. i imagine it's gonna take ******* around with it to get it close like i had to do with megatune. i don't really understand the problem since it's output is 0v=10:1 afr and 5v-20:1 linearly.

For the gauge type in tuner studio did you select that gauge under project properties AEM gauge 30-42xx and then calibrate afr using aem linear 30-42xx?

Next step will be to email AEM for their AFR vs voltage table and plot it against what tunerstudio uses in the inc file folder using excel. If they match, then I would trust tunerstudio.

After looking into this a bit further I've found that it is only the non-linear aem that has a reference table. Go into the lambda.ini folder and look at the equation for converting the voltage to afr. The use the voltages that you receive from the AEM folks and see hat afr spits out. This is very easy to to do in excel.

I cant remember what I used, but in MT we could never get Saint_foo's AFRs to match well, in TS the were spot on. Yes the AFR targets were in volts, but whatever thats an easy conversion.

page 9: http://www.schnitzracing.com/manuals/AEMWBK.pdf

it outputs 10-18.50 AFR at 0-4.25 volts

I got the car out for a little while yesterday afternoon and played around with the autotune. Well, sort of. I unchecked the "update controller" box so I could see what changes it wanted to make before I allowed it to make them. I ran it on "very hard" since my table is already pretty well dialed in. There was traffic so I couldn't hit as many cells as I normally would. Previously I had been letting MLV do its thing but I would do some of my own smoothing. Like other people here, I found that the numbers autotune wants to run make my table look intuitively less smooth, but I'm just gonna let it do its thing for another few sessions and see how it ends up. It left most cells alone but it wanted to pull 1-2 points from most of my 2400 rpm column, and a few points here and there in the 20 kPa row.

I also took some datalogs at the maximum rate it will do, and TS still appears to be totally free of the occasional comm resets I was getting in Megatune. I would think a noisy CAS should be logged by both programs, but TS seems to be immune. Does TS run a filtering scheme to ignore the spikes?

Another feature I'm diggin is the compare tune function, where it will give you a difference report between two msqs. So if your junk happens to get corrupted you can compare to an older known-good msq without having to hunt for the problem or sift through every single window with Megatune's report function hoping to spot the problem.

a little confused here, if you look at the charts on pages 5 and 6 it shows 0v=10 and 4.99v=19.98
and for whatever reason ts shows mine in afr when in ms i could never it to do that

I have had tons of problems with MT corrupting tables and files due to the numerous comm issues.
TS does not seem to do that

This is awesome can't wait to use it. This is why I'm getting all my buddies on ms.

I got TS up and running yesterday and drove the car some today with it. I have noticed that the AFR's still don't match on the gauge displays, but the AFR's on the AEM gauge seem to be very close to where I have the AFR programmed in TS. So not sure if that is just a gauge display problem in TS and MT.

So far I like it but I think it eats my laptop battery for lunch. It doesn't seem to last very long.

I have my settings on easy and have let it tune in boost. I have not studied my tables though because I am fighting a virus on my home computer which is taking all my free time.

My understanding is that the live tune will adjust your VE table to try to get the AFR as close to the target values as possible. If it is interpreting them incorrectly and displaying the wrong AFR on screen, then it should be tuning incorrectly as well..

I had a similar issue, ended up changing the formula used to convert volts to AFR in a couple of places (ini files). I can't remember how i came up with my formula but it involved data points, excel, and a trend line.

I'm going to work on relocating, rewiring and grounding my AEM and go from there. Thanks for the help. I may need more later.

Let me know what your results are from regrounding. I had mine grounded to the head (brown wire) and chassis (black wire). Seemed ok. Then after reading the instructions on FM's website I put the black wire on the head and the brown wire to an MS ground. Seems about the same.

What do you guys use for Lambda Delay in ms ?

Not sure I understand that ( ? )

Also, Is it better to set your filter using low KPA rather than RPM ? I figure that way you can tune high kpa low rpm such as when the motor is under high load.


Thanks

Poobs!

I think you'll get some insight at msextra forum, thake a look at Megasquirt MSEXTRA and MS3EFI • View topic - VE Analyze Live - A few questions.

This may seem like dumb question, but where does VE Live get its target data from?
