  • Does the B58 run high IATs?

    I'm seeing like nearly 30* over ambient just cruising, and its not much better at WOT. That, despite running a sealed CAI. Is the IAT built into the MAF, or is it being read after the turbo? IGN ain't looking all that great either, and its boosting way too much so maybe Map 3 isn't the way to go on straight 93 octane.

    Trying to get a dyno appointment for next week, so seeing if I can dial it in pretty close on the street. Really need someplace where I can do pulls in higher gears.

    This log looks completely normal for 93 octane.

      Really? Cause it gave me the Boost Over Safety code.And the IATs still bother me. I'm used to trying to keep them around ambient, not over.

        IAT's are staying pretty stable so it's not a tuning issue or too much boost. Boost curve looks fine...map 3 is an additive map. How does map 5 do?

          Heres Map 5. I have no idea what it recorded. I know I did a few WOT runs, so hopefully something is decent. It feels weaker on this Map than it did on the other one. Its more linear though.

          Thanks.

          Oh yeah, this is with E32 and 93 octane. 5 gallons of E85 that tested at just under 85, and 13 gallons of E10 93 (that actually tested at E12).

              I'd raise FF to 60 and see if that help reach boost target better.
