Thread: NismoTronicSA Startup Calibrations Update

I just added a bunch of new startup calibrations to the web server that are available for download.

If you are starting out or are looking for a new tune, it is highly likely there will be something here to help you out.

As always, if you need something more specific than what is listed there, just ask me for a custom calibration!

Any updates/request or even file contributions are welcome!

Hey John, some of the files have "MAF overboost limit table" wrong.

For instance, "B13-SR20VE-330-N60-MAF.tcd" have the whole table set to 140, shouldn't it be at 255 the whole way so there is never a chance to hit boost cut with a N/A tune?

That MAF value depends on your scaling. However, during my data logs, with a Z32 MAF, the transition from vacuum to 0 psi occurs at about a MAF value of 56-64 depending on MAF scaling. If that's the case, you won't be hitting MAF overboost fuel cut at any point on a N/A vehicle unless highly worked over. On my EFR turbo, if my memory serves me correctly, I am seeing MAF value of 140 at about 12 psi boost ("stock" Z32 scaling). Not sure if 98% of the N/A vehicle will see anywhere near those numbers.

However, I could be far off on this. Just my observation.

It shouldn't hit 140 on the N60 MAF, but yes I did try to go through and set them all.

I will make that change to that file so there is no issue with the overboost on the N/A base tunes.

Thank you for pointing it out!! I did my best to catch all of them, but it's a lot of files to go through.

I see most of the tcds disable the knock sensor and analysis. Is it the norm?

Just updated the software to latest and loaded one of the startup calibrations (b13det-550-z32 tcd) and for some reason the live data was not showing up. Any ideas? Battery was dead and on charger, not sure if that somehow could mess with it. Last time I had it hooked up, few months ago, had no issue.

Did you disconnect pins 7, 14 and 15 previously? If not, remove those pins from the ECU harness and give it another shot.

Also, make sure you aren't using a battery charger (on jump start) with the stock ECU as it has caused issues with the ECUs.

Dont think i've removed any pins from the harness, not sure why i would've. And good to know about the jump start wont do that anymore.

also what are these pins for exactly?
