Well i have an issue, my flex maps do not work anymore? No matter what value i put into the fuel compensation map there are no change to AFR's. It was working previously and just stopped now. I just retuned the car to run on pure E85 now and i must say the power difference is massive! The car is muc...

Fixed the boost leaks and touched up the tune, wow what a difference! Hitting 45% idc and 4.705v in the afm, the car is pulling really well. Cant wait to get some e85 into it!

Sorted out my pipework but i can still only get 14PSI peak boost and when i do set it to 14 the AFR's dip stupid rich (11.5 to 10.4afr)... Also if i set the high load areas to raw values of 30 for example, AFR's will swing wildly by 1 full afr point. I ended up turning the boost down to 9PSI and i m...

Just a quick update, on 11psi boost I'm hitting 4.675v afm voltage and 37% injectory duty cycle with the afrs in the low 11s and 17 degrees up top. Not bad at all for stock turbos! Only problem is it seems i have been tuning with a big boost leak, afrs are all over the place on full noise and when i...

Increase your TIM further until AFRs are 14.7:1 on cruise with O2 sensing on Your fuel map will be very flat with 1000CC injectors. Probably around 25-30 filtered values Refer to the injection section (Sections 8-10) in the software user manual. I've updated it containing info how to tune this in w...

Hey guys, i've recently installed Bosch 1000cc EV14 injectors into my Z32 300ZX, installed nistune and a GM flex fuel sensor. Now i've used a factory ROM, gone into "resize injectors" and changed the values from 370cc > 996cc (512 > 190 T.I.M). I have also adjusted the latency as per the d...
