In regards crank enrichment, i have done a log on startup it appears to be starting at 10 volts. The battery is a brand new larger AGM battery and i have run a 50mm2 for both positive to starter motor and negative to the factory engine bay point. I converted it back to the factory AFM for testing so...

Hi Matt, Thanks for your speedy response. I did read that the VE values were doubled in the Neo tuning guide just wanted to make 100% sure before really getting into it, thanks for the clarification. If you could give some feedback on the responses below that would be greatly appreciated. Looking at...

Hi, I am having an issue with my VE indexing. In the log it will show what I think is the correct ATPS value but on the VE fuel table the cursor is always way further to the right at a higher ATPS value. What is causing this? I have a R35 AFM in a 3.31 inch tube so I have used the VQ generator and o...

What board if it can take one would a 93 Nissan Sentra gt, ecu number 73y05, motor is a ga-16 take?

Scarles ignition coils are cheap and nasty, that's where i would look first.

I have had someone ask me if there is inlet air temp correction support on a r32 rb26dett. As i have had no experience with these engines i have done a bit of searching and found that they do in fact run a IAT sensor of some sort. How do these operate standard? I cannot see any support in NIStune or...

Hi, i am looking for someone that can get me a RB25DE+T tune for a r33 series 1 running on a R32 ecu. What is the best fix for the TPS idle signals for these?

Can i ECR32 ecu's MEC-R232 and 233 08U01 and 08U11? They DO NOT have a knock board in them?
Can i also use BNR33 ecu to run a rb25det s2?

What sort of modifications would help?

i need to pass an emissions test on the above vehicle and am wondering if i install a nistune would it be difficult to tune it so there are minimal emissions? i will be replacing the catalytic to help with this. Im not worried if the car has low power (i will re-tune after test) just wondering if it...

Need a JECS RB25DET NEO ECU, i am in Rotorua New Zealand

Can i use the type 4 board on a rb25de (neo) ecu but later convert to a det (neo) motor and still use the de ecu or will i be better to get a det ecu?

Made 191 kw on 16psi boost. Turbo is too small and cant hold the pressure at higher rpm (12psi at 7000rpm). stoked anyway NIStune works very well. this setup made approx 130kw on 11psi with standard ecu and injectors!

Seems to be starting better now, rung my tuner and he said to change latency to 770 and k constant is a little higher at 175 and starts a lot better. We will see how it pans out tomorrow... thanks for all the help anyway!

I have just installed GTR injectors over the weekend. Had a very hard time starting the car after i re-sized the injectors in NIStune. Tested resistor pack, fuel pressure to rail would not start. Pulled CAS out and turned over with ignition on to check injector pulse which was fine and then it start...
