Doh! thanks.

The manual says "Only available for some (RB series) vehicles", and if I look under Maps -> Enrichment Tables; there's
Crank Enrich
After start enrich
Enrich (Cold crank)
Enrich (Warm crank)

So it looks like the rb26 doesnt have them, can anyone confirm?

Hi Tommey, If you cant understand the docs then its probably better to ask other owners in your area who they recommend getting a tune from, and taking your car there. If you make a mistake with the tune, and then drive the car hard, you can destroy the motor. Maybe take a backup of the current tune...

Gizzmo Kmon has a 0-4.5V analogue out, how difficult would it be to push that into Nistune for logging? I would need an analogue to digital/serial converter, but could one of the wideband input types be used to get something displayed?

I asked the tuner: "What was slowing down? Response in the Nistune GUI? Re: the change in timing advance, did this occur at the same time as the slow down? Was the timing change noticed by knock or via monitoring signal to the coils or some other way? What's the PIN?" He said; (i had asked...

Thanks for your comments Matt - I suspected there may have been some misreading of the symptoms. It sounds you are sceptical that there's anything wrong with the ECU, as the description doesn't match the failures you've seen. I wondered if the "slowing down" was just some intermittent rs23...

Hi All, RB26 with -7 aka R34 N1 turbos, 550 siemens injectors and early Type 2 board. Made 305kw @ 17psi. I was interested in pushing the boost up a little further, and added Nismo MAFs. Tuner had issues with the old boost controller not re-training, so it was replaced. Had issues with ignition and ...

Hi Matt - any ideas on this? Or will I just have to get it fully retuned?

Re the comment ""Z32 VG30DETT (GTR ECU) (500 HP)" is just for display purposes (so it displays correct MAF after using Z32 MAFs with R32)" I just tried loading the original tune, then changed the MAF to; Z32 VG30DETT (500 HP) -> causes slight tweak of MAF VQ curve (a bit lower in...

Here's the VQ map.

Its 10:1 at cruise... I'll get the VQ map - is that the one called VQ translation in Nistune?

Had a play with K using the injector resize, 550 -> 250 gives an idle of around 17:1 and 200 gives around 14:1. Since that's a massive difference I'm worried that I did something wrong with the Halve / Double settings...

Ok, i've installed the MAFs, changed the MAF setting in Nistune and reset the fuel trims. The car starts but runs too lean to hold an idle. Pumping the accelerator works, but holding the pedal down doesnt. I assume i now need to tweak K by using the injector resize option, is that right? And to adju...

Thanks Matt. FYI the link in my post has the Nismo vs Z32 graph, and it looks pretty close. AFAIK the Nismos are just Z32 guts in a GTR AFM shell.

VG not VQ...
