Nistune Forums

Matt, sorry for the delayed reply. attached is the RPM pull. one thing I noticed is that as I increase RPM the mismatch gets bigger. At the 3000 RPM range, the gage on the car indicated 500 higher, at 4K split is 700; by the time I reach 8000 on the car gage, the nistune is only registering 7K RPM P...

So I installed my R35 MAFs and loaded the VQ maps using the "change MAF" function. I did a run and noticed the indicator on the input tracer would go into the middle/high load areas quickly i.e. hitting the 50 load collumn at 3000 rpms. the interesting this was that load never went off the...

Matt. I installed the R35 MAFs and the stalling is gone. The tubes I used are a kit from SPECTRE P/N SPE-9405. It is a universal kit that uses a 3" tube

***PROBLEM SOLVED*** using a mutimeter checked the pins on the GTR one is 12V supply to the MAF, the two middle wires can be spliced together for they are grounds and the fourth wire is the signal. I have attached a pic with the proper markings. The R35 MAFs are a huge improvement over the Z32. I am...

does anyone have a diagram/picture they can provide on how to wire the R35 MAFs to a R32 GTR?

I have seen the pinout diagram Matt posted long ago but it does not specify the BNR32.

Thanks for the help.

I recently conducted several pulls on my car and noticed the log never recorded anything above 6400 RPMs while the RPM gage on the vehicle has shown RPM above 7000

My car is a 1991 R32 GTR.

I have searched the forums but have not found any info.

Any info you can provide will be greatly appreciated.

Matt. I adjusted the latency to stock and made adjustments to TIM. on my run today the car still managed to stall after a hard acceleration. My MIN LOAD (TP) is set at 8 accross the board. How high should i go to keep the car from stalling? This time I lowered my boost to 8 psi. the load index never...

Matt. Thanks for the reply. The injectors i have are hks purple ones and the advertized latency is 402 . My wideband went bad on me in the middle of this trial which is the reason it reads so lean. It is a innovate with a new sensor and heat sink. I tried the calibration,re- wiring it and nothing. I...

I need help sorting this problem out. My car has a rough tune that makes the car run well and idle well. accelation is much better as it reflects the mods below. My car is a 1991 R32 GTR wit a nistune FP board. I recently upgraded injectors from stock to 600cc and mafs from stock to z32's. like I sa...

Matt. my MAF resize issue has been resolved. I believe the issue with my maf resize was that the option named "Z32 VG30DETT (GTR ECU)" was bad. I re-did the procress using the option named "Z32 VG30DETT" which worked fine.

attached is my bin file.

Thanks for the help

I recently purchased a pair of R35 MAfs for by R32 GTR. I plan to use the 6 inch long tube from MRP Machine Shop, but I can see issues fitting in my engine compartment. I have deleted the stock airbox.

can anyone send me a pic of their setup? I would really appreciatte it.

Thanks Matt. I do have a FP board. what does it mean when you say "adjust until it reaches the end of the fuel map"? Should I adjust only TIM? Or K constant only? should I tick the "auto TIM" as I adjust Kcont? how much of a split on my MAFs is too much? my logs show an average o...

Update. I decided to use the vq transfer generator and using the data for the hpx n1 maf and scaled to 33% i got the car running and accelerating well. The only issue is that the AFRs are a bit rich.

I recently upgraded my injectors to HKS 600 cc injectors and a set of z32 MAFs. My car is a 1991 R32 GTR. with the following mods R34 N1 turboes pomcams 260 cams catless 3 inch exhaust NISTUNE FP ECU on the injector install, I followed the menu on the nistune software to include the adjustment on th...

Right now by boost controller is working fine. it turns out my vacuum/pressure lines were not installed right. I still have the solenoid bypassed, but will connect soonest.

thanks for the reply
