Mechanical or HPTuners issue ?? 2005 GTO
418in ls3 TH400
Car has been running great. No issues at all..
Approx. 1 month ago the car stopped reading the commanded Timing table
and will run at 29* at WOT no matter what numbers I have it commanded at.
Curious if anyone has ever run in to this issue.
Could it be a cam position sensor ?? Speed Sensor or something screwy with HPTuners ??

With the TH400, it could be something in the neutral safety switch (or clutch switch if it was an M6) that is losing connection and sending it to the park/nuetral timing tables... saw it once on my TA after putting in the TH400 - sent it to the park/neutral table while spraying nitrous... bout had a heartattack when I saw the log... neutral saftey switch on my aftermarket shifter had come loose. From that point on, I make the park/neutral and in gear idle spark tables the same as the high octane table so there is no chance of that...
