Looking for a N/A tune for my EUDM 10AE
Hi all,
I've got a tune from Reverant that my car will start up on and I can autotune it to run reasonably well. However, it's for a F/I car, so I'm only using the bottom half of the VE/AFR tables (up to 100).
Is there an easy way to modify an F/I tune to fit an N/A car, say, by changing the y-axis values of the relevant tables to go from 0 to 100 in smaller increments? Are there other tables I should adjust?
I'm using TunerStudio and my car is close to stock apart for the DIYPNP, COP kit, LC-1, GM IAT sensor and a cat-back exhaust.

If you are not going to switch to F/I at some point soon, then I can mail you new N/A tables. You will have to autotune the VE table though, as I don't have a properly tuned 99-00 1.8 VE table (stock Miatas are rare these days).

This is what I got so far (the fuel map is far from done - I almost just started to auto tune):
It's not going too bad, actually. It starts and idles nicely. It pulls fine too. But when I come back to idle, it dies promptly.
Any comments are welcome.
Reverant, if you have something of a better starting point for me to work from, I'd be most grateful.
Cheers,

It's a bit weird. When coming back to idle from higher revs, the engine stalls. I can keep it alive with 1% throttle, but if I lift my foot off of the accelerator, it dips and dies. If I have kept it going at 1% throttle for a while before I slowly lift my foot, sometimes it will only dip really low and slowly come back up to 850 rpm where it will idle perfectly.
There is absolutely no problem with starting the engine and settling at idle.
I tried going a bit richer (13:1) between 0 - 1000 rpm and 25 - 45% afrload. No change.
Any ideas? Any idle settings to check or post screen grabs of?

The two bone stock '99 - '00 present both produced 137.5 PS and 155.6/156.7 Nm.
Here's my dyno (note it's a '99 on RON 99 fuel with a Larini cat-back exhaust as the only "power" mod):
My power is fine compared with the stock versions but I'm down on torque. I suspect my VICS might not work as it should.

No, the EUDM 99 manifold is different than the EUDM 01-05 manifold. In fact, the 99 has VICS and is exactly the same as the USDM manifold. The 01-05 is the square-top manifold.
Jason, the dyno plots I posted above are of my own car:
Bone stock: 137.7hp/15.6tq
With air filter kit: 143.2hp/16.2tq
