Thread: Is my MAP sensor bad?

This is definitely harder than a MAF fuel map. I'm having to add tons more fuel just off idle so I can actually rev the car without it falling on its face.

I ended up setting my Load scale from 380mbar/38kpa to 1000mbar/100kpa

I'm seeing that no matter what you use as a load source, tuning a 90mm TB car is a pain in the ass. With the stock 60mm TB it was so easy. Cruising speeds is not far off from the idle cells. It does move around, but not buy much lol... Driveability suffers some, or a TON if you suck at tuning. WOT is fine though.

I'm not sure if this would really work ok BUT the only way to make it more driveable off idle/crusing is to :

example: BEFORE

300mb/350mb/400mb/450mb/500mb/550mb/600mb/650mb/700mb/750mb/800mb/850mb/900mb/950mb/1000mb

AFTER

300mb/325mb/350mb/375mb/400mb/425mb/450mb/475mb/500mb/600mb/700mb/800mb/900mb/1000mb

This would kind of give more resolution BUT this is just funky

I wish the few ITB Guys and 90mm plus guys would chime in on some tuning secrets

You can always send me your file so I can take a peak.

I might be able to point out a few things to help you out!

Also, any logs you might have with AFR and whatnot would be helpful.
