Yup, sorry, re-read the op. The first two times I read the things tried unsuccessfully as things I'm going to try.

What doesn't make sense is that your lean spike is corresponding to exactly where the o2 should be seeing the fuel injector spike? How much exactly did you increase the stomp comp by? Last time I had to tune transients from scratch the default values in the ecu was like 6 and it needed to be like 30 (cant remember which value it was). When I first stared adjusting it I though it wasn't doing anything. What exactly can you adjust on your transients? Amount of asynchronous pulses and pulse width right?

I don't know how your adaptronic blends the tables together, but running alpha-N with boost is generally a bad idea. Why not run speed density?

As long as you can choose the blend and run alpha-n for idle and low rpm and then get to complete map by the rpm the turbo spools its ok. I've tuned boosted cars on straight tps, and it sucks a massive taint, even when they're blower cars with airflow more or less always being equal related to tps. But I refuse to ever do it again unless a large stack of bill are placed in my hand, because it takes forever, and makes you want to bunch babies holding kittens.

you cant tune a tps-based turboed car?

You can. But if you dont have some sort of MAP compensation its going to be tuned to have a rich spike when you first get on it if you're above the boost threashold. It works, but its a terrible idea. :fael:

It uses a table for TPS x RPM with direct msec values or VE scaling if you want, and a second MAP x RPM table where a 1.000 means 100% fuel value in TPS table, 1.200 = 120% and so on. You can leave the under 100kpa area almost at factor 1.0, because there isn't a big change in manifold pressure but a big change in air mass, more related to TPS position. Over 100 kpa the MAP x RPM table do the trick for increased manifold pressure with increased air mass at the same throttle apertures.

i see what youre saying.

This sounds exactly like how I had to tune, except you have a 3d table for your map compensation because you have rpm I only had the ability to skew vs map. How I managed to make it work somewhat well was making the table compensation map look like a good ve table (vaguely) and then fine tuning it in with the tps main fueling table. You've got a better setup there and it sounds like how you have it is the best setup for itbs. I still would make the in boost part of the map based table look like a generic ve map though and then tune in the tps map for fine tuning of it. Course during spool up you'll have to fiddle with the two to make it work right. This is making be remember the days of.

Itb tip-in has a LOT more throttled volume than single throttle body. People have a tough time as it is when n/a going by tps and not map based enrichment... Turbo+itb is like a 9.5 of 10 on difficulty comparatively. It's going to have a VERY narrow window where it will work correctly. That's Also why you see progressive throttle linkages.

The two pics of your engine bay just gave me a migraine...thanks a lot asshole!:giggle:
