It's an audible ping. I've had several supercharged cars before so I know the telltale sound of detonation but this is the first time I've dealt with a chip controling my timing. I can't see any reason i should be getting detonation at that low of a boost level.
I'm pretty sure about the chip. I did get the car recently but it's been through 4 or 5 tanks of gas already...I don't have anything else to put in it for a chip...
I have an 87 turbo t-type with the only mods being jay carter 28-93 chip, walbro hotwired fuel pump, 3 inch mass air pipe and 2.5 inch exhaust. I run nothing but 94 octane in the car and yet I'm getting detonation at only 8-10 lbs of boost....Has this happened to anyone here? I don't have a scan...
