Hi Folks. I just got my HP tuners MPVI2 last week, and am learning as I go. The Wideband is not hooked up yet; that is next week's project.
Car is a 1986 Monte Carlo SS with 3.73 gears. Tranny is a 4l80e. Engine a 6.0 with stock bottom end, and a CBM motorsports LS450 cam (220 and 228 duration @50, .581 and .588 lift). Computer is a blue/ green P59 from CBM as well as the harness.
Stock Truck injectors, Stock truck 75?mm DBW TB, corvette fuel regulator set at 58psi,
Anyway, I figured this thing would roast the tires off the line, but it doesn't. It seems to have plenty of power higher in the RPM range though.
I looked at the trans stuff, and didn't see anything limiting torque, however I have no idea what I am doing yet.
I will be taking more logs this week to sort out my cruise control issue. If any of you experts sees something in my file/s that looks obviously wrong, please let me know.
What I looked at:
TB opening goes from 16 to 96%
Injectors are only at 68% in WOT
Spark/ Advance, no red flags
1 instance of knock detected
