Pinging!

[croat]

After the instakllation of the GT-RS turbo i have noticed some pinging (the dash warning light is coming up when giving it a bit). I took it back for a re-tune, dropped the boost back to 1.2 bar and took the timing back a few degrees and richened the mixtures to i think 12.5 and there is still pinging. I raced at the creek last night and it pinged in 2nd gear at 4500 rpm to redline then the other gears it was fine. The tuner said it is that the engine is getting to hot?? any ideas?

bigger fuel pump fuel reg ????

I have done everything regarding fuel system. injectors, pumps 044 and standard, sard fuel reg, (filters, plugs, all oils, and gaskets were replaced when turbo was fitted). Have a Power FC for management. Dont have cams, plenum or anything like that. It does not ping when i put the boost to 14psi but when it goes up from that it begins, also you cant hear the pinging so its not bad at all just the slightest knock.

Not having a HC doesn't help much !

What fuel are you running, If you'r running down the strip i'd use BP ultimate + Nulon Octane booster, this stop detination - Could be a bad batch of fuel.

Other wise its down to the tune, you said 2nd gear... get you tuner to do the map tracer for second gear, find the detination points and pull 1º - 2º of timing & add more fuel in thoes load points.
