Keep in mind, that is a visual sample. Your numbers will likely be very different.

The small thing: Did Deatschwerks provide a latency figure @ 14v. This mostly effects idle, cranking and anything else with a low duty cycle. The bigger thing: Did you use the "Change MAF" tool with "Adjust K" checked? Going Z32 MAF can be a big leap, Its HP rating is almost doub...

It was recommended that I adjust my closed loop scales. I read the manual and a post on here. I think I understand but I created a graph for visual reference to help me along the way. If I'm understanding this correctly: 1) The shaded area of my graph is where the ECU will stop using long term trims...

This is driving me crazy, looking for some insight. D21 MECM-131 ECU run with Nistune Type 1 ran fine for years on a VG30 with very little modification until recently... Just installed a supercharged v6 bored out to 3.4L, Cams, internal coatings... the works... Eclectically the main difference is Z3...

I got this when I tried to email you on 23 Dec 2025. Are you using a Gmail address full time now? Nistune contact page still directs us to info@nistune.com (https://nistune.com/contact-form) Message not delivered There was a problem delivering your message to info@nistune.com.

I've not seen this type, but both look lefit, but might have different calibrations in them Agreed and Plugging in confirms it; the N62 (inside and out) runs the engine leaner than the N60 (outside label only) So I proceeded with the housing swap. I also spotted some visual differences. Untitled.jp...

I thought I was swapping an N62 for an N60 into my custom housing but when I popped the lids both circuit boards have "N62" printed on them and their outside labels say otherwise. I wrote in the top left corner what they should be in blue marker. The N60 (with N62 board) I pulled out of a ...

1987-1988 VG30E (NA) Thanks, I will keep that in mind!
The donor vehicle is incompatible with nistune (another truck) so a Re-pin will happen no matter what ECU I use.

Vehicle has been parked for some time but My last thoughts were the difference in KS Its a PITA to reach in the valley and I was just gonna cut the harness and see but I may be taking other directions. Sadly sell it as my collection is getting too large (by some definition) My unfinished supercharge...

Ok here is what I have tried so far. The first value was default the second value is what I tried. 7FBA 06 > 00 no visible change 7FA3 01 > 00 no visible change 7FA4 68 > 00 n/c 7FAD 19 > 00 n/c 76A9 46 > 00 n/c 76AA 00 > 20 n/c I saw no visible changes to AAC behavior but maybe I need to try other ...

I'm not seeing where I make these changes am a reading it right?

I just plugged in an ECU off ebay (a18-60 k34)to test it. AAC behavior was different, the problem was less exaggerated and the AAC value did not go all the way up to 80 when driving. I downloaded it to my pc and I'm going to copy the needed items to it and see how it does. Weather has been warmer s...

I did a short drive today on a stock ecu I bought to test it. Map tracing was not available but from what I could see in the short period I don't think there was a 5 degree drop. I downloaded the map before plugging the nistune ecu back in and I will copy the minimum needed items from my current tu...

You may just have to map for an extra 5 degrees of timing above 2600 (to achive target timing) That approach sounds like I could make tons of mistakes I did a short drive today on a stock ecu I bought to test it. Map tracing was not available but from what I could see in the short period I don't th...

I've had a look through the AAC routine in this ECU today (traced back from the Consult AAC output register), I can see references to the Target Idle RPM lookup tables in the routine so this is definitely the correct code However it's nothing like the HCR32 which at least had tables etc which we we...
