LANCIA DELTA INTEGRALE HF 16V rallycross cars.

2L engine
4 Cyl
turbo
12-1 toothweel with HALL trigger
- no camsync
wasted spark coil
4 bar MAP sensor, about 1.7 - 1.8 bar boost
permanently opened throttle body for ALS

There are 2 cars here, they are almost the same, except one of them has high impedance injectors, and the other have low impedance injectors. The cars was running succesfully from a year with VEMS, and with 1.0.38 firmware, everything was OK. They use start limiter and boost control too. Now the cars came back. They need ALS.

News:

The car works good with this 12-1 HALL triggerwheel and 1.1.12 firmware. But ALS is not works good.

ALS

using 1.1.13 firmware now

config dump:

You can see strange things in the logfile. Look at the samples at the time 2497.882-2502.655. You'll see, when the throttle is released, the ignition jumps to -64 deg for a short time, not to the correct ignition retard. Not good.

Also look at the samples at time 2507.399-2510.781. You'll see that the Ignition cut jumps to 100% after releasing the throttle. Not godd also.

And here is the ALS settings:

als_cut_mintps=4D

als_max_cut=22 als_cut_maxtps=66 als_enrich=0D als_react_tps=40 als_retard_rpm1=11 als_retard_rpm2=12 als_igncut_rpm2=23 als_retard_mintps=4D als_retard_maxtps=66 als_igncut_rpm1=14 als_deact_time=06 als_deact_egt=00 als_retard=3C als_rev_limit=5A als_tks_channel=FF iac_warm_rpm=0C

</code>

throttle is always open
- using the gasoline-eater soft idle ignition cut for idle.
when the ALS switch is turned on, soft idle ignition cut should be activated only after the time limit is reched.
- so press TPS fully (or above als_cut_maxtps) and release: than softidle should only cut above iac_warm_rpm after 05 seconds
