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.
