Bogging Down at WOT
'92 LT-1, Vortech Supercharger 12psi, 383, alcohol injection, superfueler (Carroll), MSD. Uncertain as to chip origin or binary modifications...
Went to the strip at the weekend, got some datalogging. Car runs fine up to about 3/4 throttle then bogs down. Any advice on the folowing datamaster readings? (Note - some data errors detected during WOT)
zero spark retard (good)
INJ DC calc averages 75 max value 82
BPW ms 9.2-9.5 both sides
O2 Millivolts - always above 800 at WOT, RHS is higher by about 60 consistently throughout the run, max 901 RHS 830 LHS
Lterm and Sterm counts - very solid at 128, occasional 190 'spike' on RHS Lterm count
Closed Loop at all times
TPS % shows max of 89% (3.22V)
EGR inactive, CCP inactive except for one record of 25 each at 50MPH
MAP max 104
Spark advance 36.
If anyone is interested I'll post the .uni file here.
Thanks guys!
