    TCU tuning

    Since HPT hasn't given us access, what software can I use to read/write the TCU? Curious to check out the tables in there.

    Thanks

    You're going to need a sticky tire on the street - there's no way around it. An LSD would help, too (I have one but haven't installed it). My best 60' on the street is a 1.95 on R888R tires, but...

    The 1/8 trap speed should be good for 120 or 121 in the 1/4. The 7.95 ET would probably get you about a 12.1 in the 1/4. You'll need a better 60' to get in the 11s, I think. But it looks like the...

    Dragy is quite accurate, always well under a tenth of a second off in my experience. I just reviewed some VCM scanner logs from the drag strip and it was kind of a pain to match up with timeslips.

    This is looking more like high pressure pumps to me. I have a log very similar to yours back when 1 or both of mine were failing. I replaced them and it resolved the issue.
