Help with MAF issues, running too rich
Hi,

I'm just starting to work with the RT ecu and I'm stuck with the MAF setup, I'm using a DE MAF (part 22680-2j200) from the stock P11.

This is the TCD I'm using,

And this is the 3rd gear WOT roll log it generated,

I've tested all the other MAFs but the only one that works is the VE MAF but the issue is that it runs extremely rich.

Another issue I have is that I'm running a vtec switch for the cams and when I go past 7600-7700 the rpm signal appears and dissapears repeteadly switching the cams on and off in the way.

Ok deposit files sucks for this, ive uploaded files to the forum before, cant see the link from reply, but think you can from a new thread.

AH, you cant attach files in the Nismotronic section, go to tuning and post there and you have a option to attach files, way easier.

Did you find a VQ for a P11 DE maf?

Got the files finally, some pretty odd stuff there. The really low numbers at high load are not ideal.

Thats a P11de Vq map, which is not listed in NismotronicRT, ive tried to work away to paste it in, but it doesnt seem to be something we can do with the software.

You can certainly paste it into NismoTronic.

Paste it into excel first.. then copy from excel and paste into nismotronic.

The P11 SR20DE MAF is now available.. run NismoTronic with an active internet connection and it will auto update the MAF section.

After you update your VQ curve, adjust your kvalue and current injector size to get the car close.

Then start fine tuning the fuel map.

OK, modified the TCD and went for a drive, this is the log I got,

I selected the new MAF and then started to play with the K Value until I got around 15 AFR on idle.

The fluctuation you see at the end of the WOT run is the issue I was commenting about the RPM signal getting interrupted above 7400 rpm (or so).
