17 psi normal on 91???

335ispooling · 02-27-2014, 05:35 PM

did a few pulls the other night from 3rd and 4th. 15 - 17 consistently on map but all i have is the dci and 91 octane and im in denver so high altitude. is this normal?

raceyBMW · 02-28-2014, 06:38 PM

Depends, is it a peak right after shift, and then settles down? If you are running 15-17 to redline, then no, that is not right at all. For DCI only, you should be at around 10-12psi or so.

AlpineSwift · 02-28-2014, 07:56 PM

racey, I'm not at my computer but he should take a look at my logs if you still have access to them. 17psi peak at 4Kish rpm is fine. Anything over 17.5 and I'd be asking when you plan to add e85 to the tank. I'm at 16.6 peak and I'm occasionally mixing e85 in the tank to keep the car happy.

335ispooling · 02-28-2014, 08:38 PM

17 at 4k- 5k rpms then declines

chepy24 · 03-01-2014, 11:12 AM

agree with all the above. I got scared shitlest when i first saw the cobb spike at 20(where it tells you the highest and lowest) but then looked it up and saw it was nothing to worry about haha makes me still feel like a noob but anywho add some e85 in there and you will be happy

@Alecas4477

Do you have logs you can throw up on datazap for us? I'm not worried about your boost because that's perfectly normal. I'm worried about your IAT's on a 3rd gear pull. If your car is anything like mine was before my FMIC, you're really going to need to invest in a new front mount.

Yes 15-17 is normal from what I've read on 91 OCT. My max reported is 20.1 PSI on the Stage 1+ FMIC but I read that's a shift-spike.

raceyBMW · 03-03-2014, 11:56 PM

Yup, spike after shift is not a big deal, everyone gets it. What you don't want happening is running that PSI to redline on stock turbos. Probably no problem at all.

There isn't a clear 3rd gear pull anywhere in this log. Start in the basement of like 2000RPM and go all the way to 6600ish. A little extra in 4th is fine but without a clear 3rd gear, I can't figure out what's going on with your tune.
