Thanks Boosted Tuning, will try few more attempt for the scaling as now matter what scaling values i throw in, its the 943cc is the closes to 14.7AFR ecu AFR.

Will a re-circulate bov helps on my stalling problem due to sudden rich while throttle lift off?

 

It's one of very first things to check, when you have stalling problems.

 

Is it ok when I have to enter about 0.5-1.2 unit lower values into my high octane fuel map to get correct AFR output from my LC-1 when running WAT from 3500 till redline?

The car is Evo 8 260 with standard injectors, japspeed downpipe and boost about 1.5bar(smaller pillow bar). I use the 96530006 ROM with standard MAF and injector values.

I will install the walbro fuel pump this week, to be sure that the pump is not running out of duty.
Thanks for any ideas.
V.

 

Yes. The fuel maps are just numbers. It doesnt matter what the fuel maps AFR says. It only matters if the right AFR is being recorded by the wideband.

 

Thanks
