Detonation problem just got the motor in the car, its a 383 lt1 with LE2 package, computer was tunned by madz28.com. It has 30 lbs. accell injectors, new O2 sensors, like only 10 to 1 compression. It runs really good until it warms up then it falls on its face a pings really bad, even with no load on the motor. Is it a faulty tune or what? Has new opti, wires, plugs. Please help
I would get it tuned, and have them adjust the Timing. What plugs are you running? Mine is detonating past 5500 RPM's when it warms up, I am going to change the plugs out.
sure its det? i bet its ignition problems...madz28 is normally very on, try some better gas maybe some 105 octane and see if it goes away before you go get another tune, will save alot of time and maybe some money

if its saying on the scanner to check connection then that means there isnt any power getting to your computer.
my car ran with 2 cups of water in the computer (not good but it ran) and thats when i figured out my comp was bad. i put a new one in and the scanner works and the car runs good again
