Settings
 

As more of us are getting into the MS, and as many heads are better than one I've been thinking that we should probably start a settings page.

If we can work together to test and hopefully build on each other's settings then we should be able to develop a really strong default msq for the miata.

Here are my starting contributions; 1.8 NB engine, naturally aspirated.
MSnS-E 029h, Req Fuel 13.3

Good idea!
You forgot to specify your engine type. It is a 1999 1.8, correct?
I will have my default 1.6 NA setup up soon, as well as a 1.6 Turbo setup soon, I hope.
We may also want to attach a .zip containing your .msq, so others can simply load it into the MS and go.

Anyone would have some Accel enrich setting I could try?

I tried a whole bunch of setting and I can't nail it down perfectly. There is always this small stumble when blipping lightly the throttle.

I'd reccomend you try using Mapdot. It might make it easier for you instead of using the RPM accel.

I tried using Mapdot, tpsdot.. rpm base..

When I think I have it right.. the next day or after a short drive.. I always find something not quite right.

I'll post my screenie tomorrow.. You might be able to tell me if I'm far from the thruth or not.

Hello,

Here are some screenies to help newcomers start from somewhat of a running base.

That VE table got me 27 mpg average on rush hour traffic. Wot is rich but I can only tune it with a NarrowBand sensor. Up to you to modify it to your liking.

The Accel is RPM base as it is giving me the best drivibility.

The cold start and ASE got me reliable start down to 15F. But it take 2 short crank to start it that cold. (it is starting at least :) )

Hope it can help and ask if you have any questions.

Edit: 1.8 N/A, Code 29J, Req 13.4

After playing around with both the fuel and the spark tables and by comparing them to the factory computer's fuel and spark tables, I'm now running the following settings for fuel and for spark.

I have this in the other thread but it would be good idea to centralize everything.

Sparks Settings:

I haven't tested the following but it looks promising:

You should be able to use these values in EasyTherm

Maybe this is an easier/cleaner alternative to fitting a GM CLT sensor?

Just so you know, I used the averages of those and my coolant read about 165 when it was warmed up. So I just set up warmup enrich accordingly. Works well enough for me, but some may want something more precise I suppose.

All my fueling temp corrections are set to use the AIT, so that shouldn't be affected.

I was able to use the CLT, by removing R7 all together...Easytherm didn't fit on my 2HD floppy...

How do you N/A guys work out your VE tables? I used the following values and my VE table looks totally different:

Engine displacement: 1839cc
Idle: 800, 20
Peak torque: 121.7, 4500, 100
Peak HP: 142.2, 6500, 100
Redline: 7400, 100

I haven't tested it out yet but I would have thought since I got these figures from Mazda sources, they would be fairly accurate?

They will certainly work as a starting point.

My fixed idle VE is 40 (I'm now running keithmac's idle code 029L4), which I've gotten to after some mucking around, but sorting your tables out/tuning is half of the fun.

I'm now running keithmac's 029L4 code with the ignition idle control.

It's been running the car for the last four or so days and I'm really impressed with the improvement over the 029q2 idle control. The idle on the car doesn't 'bounce' anywhere near as much as it used to and for the first time I have been able to run the idle as 'closed loop' and it's a nice stable drop in revs from around 1500-1600rpm at startup.

If anyone is interested in giving it a go, I've attached my current settings below.

I've also included my current spark table (N/A) which is running more advance than the one I used to, and I've included my cranking settings and dwell control. Between the two, I'm really close to getting a factory startup.

Please note that I'm running a 99 engine from a 1.6 CAS and with 1.6 coils and ignitor. These settings may harm a NB engine running with 1.8 coils.

If you can make any improvement on these settings, please post them here for reference.

squirt 'n spark, DSM injectors

How much dwell time should I run with the 1.8 coils with integrated ignitors?
2.5ms seem to be working fine. How much dwell is possible without burning the coils?

I interpolated the ignition timing values from the "1.8 with 1990-95 ECU, NA, stock injectors, NB head" page on the Flyin' Miata Link site as a starting point. I can do some other ones if someone wants them.

I did similar thing for the 1.6 turbo map from FM. I'm using it in my setup. No signs of detonation up to 15psi.
Here is my msq for 029q2, if you want to see my idle and boost settings. also has .vex files if you're using other code versions.

What size injectors do you use? I havent been able to find out after searching your past posts.

who me? 450cc. but that's easy enough to change in the constants page.

thanks!

awesome, im gonna give this map a shot on my setup: 550 rx7 injectors, gt2554, 2.5" most of the way through ... close enough for me.

Here is my most recent datalog. It's really short and doesn't show constant cruise afr very well, but it'll give you an idea of what to expect.

ok, i have been looking at your guys's spark maps and i have a few questions..

when the table is set to kpa and rpm, and goes from 0 to 100 am i correct understaning that 100 is 0psi boost and 0 inches vac?

next..

can this map be set to retard when the car goes into boost like the bipes unit does?

and can it be set to only retard when the MAT is above a certain point??


the ms extra manual doesnt have much information when it comes to tuning the spark table.. can u guys recomend any other websites where i can get some reading material on this?

104.7kpa is atmo at sealevel (0psi). Approx 7-8kpa is 1 psi. To make it retard ign in boost you just adjust the numbers that are already present. The reason that you see numbers like 25-30 at high rpm/no boost is because the plugs must fire sooner because of the increased piston speed. This is normal on all cars. Suppose your base timing is 14 and you are at 120kpa and 5000rpm. If you put 14 in that cell then your timing at that point is equal to your base timing.

As far as retarding at a certain MAT, I don't believe that is possible. For the most part the intake temp will be almost constant at a given psi. So tune for that. Ideally you probably want to tune on like a hot day in the summer so that you know your tune will be bulletproof the rest of the year. There really wont be much if any difference though.

101 is atmospheric, so yeah pretty much 100. it doesn't retard, thats what bandaids do. it will run less timing under boost. you can retard timing by temp as well. i suggest just using my FM spark table to start it is conservative and safe.

Nevermind, i found it :P

thanx guys

I know this is only a minor thing but it says 4G63 instead of B6/BP. :)

What are you talking about??? It helps to quote things that are months old...

Oops that was meant to be a reply to this thread:
Updated 'How to MegaSquirt your Miata' article is coming together!

:gay:

updated msq, check them accel settings, smoooooooth. keep in mind they are for 450cc injectors.

variation of Al's turbosetup.msq for my 1.6 w/305cc injectors at 7psi.

I was getting a rich cruise on the highway this morning and took 45min datalog and it should be tuned out. Otherwise in boost it's dead on and perfect idle for me.

Are you still at 12 psi?

nah, around 14 now. 195kpa.
i've also been datalogging with GEGO turned off. seems to be working well enough that i could take the o2 out if i wanted.

Al, I'm using your map now at 12psi. Only had to change a few cells out of boost and a few at 6000rpms...otherwise perfect for my 460s.

Spot on idle, cruise, and boost. I changed the AFR targets a bit and has EGO on, but it barely makes any corrections....nice job dude!

thanks man, I was testing 15psi (205kpa) the other day, it leans out a little on the map you've got. i've fixed mine since then.

Yeah that's about the only place I had to make adjustments... and I think one cell at 2300 & 60 kPa needed one point lower.

Al, I have a few questions about your map; first, why are your target AFRs so rich out of boost? At the upper end of the rpm range, you have 11.5 as your target at 80 and 100kpa. Secondly, with your Accell enrichment settings, you have it mapped up to 250kpa. Why didnt you scale it down to 100 or so seeing that any enrichments are turned off in boost anyway.

I dont believe Al is using EGO, so the targets aren't very important.

I can share my targets tomorrow, I left my laptop at work.

targets aren't important at all. you should be going open loop in boost anyway.

yeah, i don't use gego. i run around 15.5-16:1 in cruise. accel enrich settings are in kpa per second, in other words its the rate of change, not the actual current pressure.

Ok so I suppose i am doing just fine with my target AFR;s then, i mainly am using them to let megalog viewer adjust my map. As far as the Accelleration enrichments, i think im gonna have to do some reading because while I understand the concept of enrichments for kpa/sec, I have no clue how the settings translate to real results. Anyway, im just happy to be on the road again after that stupid crank problem.

Braineck, what is your setup exactly?

see my vb garage.

Here is my current map. I started off using Al's map, but it has been modified a bit since. The boost map is a little crude however as much of my tuning has gone towards getting a good cruise map.

P.S. I am running a Stock Fuel system with 550cc RX7 injectors and 1 step colder NGK plugs

need help pls,i just got my mspnp,anyone has a base map for greddy turbo w/550cc and should i keep the 4.1 fmu?thanks

Get rid of the FMU.
Just adjust your reqfuel for the 550cc injectors and use the MSQ they provided you.

+1. fine tune as needed, but their map so be your best jumping off point.

Okay so I was checking out the file someone posted here as "scottsmap" and also the "turbo 11psi" and I noticed a few things in Megatune. Why does it not allow you to see what the injector sizes were for the maps, also, I noticed that the exhaust settings were using wideband not narrowband. If running a narrowband, do these parameters have to be changed as per the MegaManual?

Megamanual is the bible for megasquirt, always follow it.
Who cares what size the injectors were, you should always change the req fuel for your own car.

no don't keep it. I messed around and played with tuning on one and it was a pain. Pull the auxillary fuel pump as that seemed to cause problems as well with getting a consistant tune.

the injector size is the Reqfuel it's part of the calculation,

Of you course need to alter settings if they're different from you car. MS is good, but it's not bloody psychic.....

Unless I'm reading wrong... do we have any boost MS maps for a 1.6L with 560cc rx7s? Something to start up on... if we get oil lines made in time... I should be start up-able tonight....

Just take whatever's the closest match, and then:
1) note the req_fuel value
2) recalculate the req_fuel for your 560cc injectors
3) modify cranking pulse widths, accel enrichments and any other millisecond-based enrichments with new_value = old_value * (new_req_fuel / old_req_fuel)

That should certainly get you close enough to start up.

-Mike

so... does anyone care to share information about 1.8L map for '96 @ 6psi boost w/ jrsc?

nay of the before suplied maps will be a fine starting point.

so 1.6 map will work fine with 1.8?

Is everyone using AL's spark map as well? I've read a bit through the manual, but spark tuning looks a little daunting to me. How will I know if my spark map is optimal?

without a load bearing dyno and a set of detcans you never will, an experienced tuner will get you close though.

if your road tuning yourself, just slowly increase the timing, use your butt dyno as a guage and get yourself a knock sensor as a safetynet
