Just wrote a big reply, but lost it, so here we go again Vehicle: S14A SR20DET 740CC/Z32 MAF Please post tune file (or email to me) and also log files showing the issues I´ve driven the car only for about 600 or 700 km, because the AFR is too high for me (around 12,2 to 13) AFRS should be around 14....

Re: Anyone upgrade their stock coil pack?

You can try a slight increase in dwell time on the standard coil and see how that goes. I've not had much feedback from using other systems, except some can cause connection issues

Re: Questions for GTR33 tuning

Hi Rigo 1. Section 26 covers the auto tuner https://www.nistune.com/docs/NIStune%20Software%20Users%20Manual.pdf This feature was added on customer request, but we don't normally use it and don't recommend using it except for fine tuning (ie all base mixtures etc should be setup firstly) You can onl...

Re: Wideband AEM Failsafe 30-4900 connection

I've put an extra checkbox for Lambda output. Under File > Config > Wideband (AEM UEGO)

The AEM UEGO will report say 14.7 for AFR and 1.0 for Lambda. There is no easy way to differentiate between lambda/AFR output setting on the gauge.

Re: Zeitronix Support Added

You can just about plug any of the units we support (apart from maybe PLX) into Nistune and we will pick up both input streams and display them Innovate have built in chaining and the LM2 accepts twin O2 inputs, but that is not a gauge unit. Innovate do gauge units, and you can daisy chain those tog...

Re: hi! from a newbie in canada. rb25det neo, in 240sx

5. Injector resize should only be done once (as you found). It adjust the TIM / K constant based on old/new sizes. So keep an eye on this After resizing, adjust TIM for fueling, and K to load adjust Use 'smart' adjust since I will look at what MAF you are running and then move K constant back to nea...

Sorry I've been away for a few days so just catching up on post here 1. Injectors. if they are unknown then best to flow test them. I've not worked with R35 injectors before so cannot comment here 2. If only idle is lean but mixtures are fine at cruise, then adjust your latency 3. MAF Upgrades. Ther...

Re: M30 Ecu features

Normally M30 VG30E ECUs do not have fan control. At one stage I was using these for TB45 engines I would re-use existing outputs and convert them to fan control. So if you have the standard M30 ECU program loaded, these will not function We also had to cut the ECU tracks from the reused outputs and ...
