Hello,

I' can't find LAMFA table in this ECU. At this moment car is running 14,7AFR (lambda closed loop control) below 4000rpm even though 1,2-1,3 bar of boost (that worries me, and limits torque at this rpm). At higher rpm it uses LAMBTS and AFR is good (11,5). I would like to make it runnig open loop at WOT at any RPM (or above 2500-3000rpm), I tried to do this cheating ECU with higher calculated EGT (KFTATM table), but it doesn't work.

It isn't any problem for me to pay for working solution.

It is Volvo S70 99' 2.3T 240HP (stock: 226HP/370Nm, mod: 313HP/450Nm - now car uses the same turbo with little bigger compression wheel, green T5R injectors, fmic and 3" downpipe).
Original and tuned files in attachment.

Regards.

Round about 18856 looks like it.

There are another 2 maps at 19092 and 190E4 though that look more likely. They've been modified to 1 to force enrichment based on BTS.

19092 and 190E4 already tested and it didn't work - I suspect these maps are KFLMSKH
I will try do sth with 18856 (little expectations).

Thanks.

Thanks a lot!
1E692 is working...  not exactly as I expected - eg. if I wrote there 0,78 (120 raw value) car was running about lambda 0,9. Anyway using lamfa and klfl I reached target Smiley
