hey all. this one has really got me stumped. my ignition timing is way too retarded. here’s my setup:
Y8 head
Z6 Webb cam
ZC block
VMS adjustable gear
don’t know if this affects it but it is turbo

i had it running pretty good on my p06 with the cam advanced all the way and the ignition advanced all the way. i just switched it to a p28 chipped and uploaded the stock z6 map from crome, and now it is worse. timing is really retarded with dizzy all the way advanced

just wanted to give you some credit here mattliston
got it all figured out and working fine, but the distributor was still all the way advanced and it was really bothering me. i pulled it off and check the play in the shaft and the non OEM dizzy had a good amount of rotational play. i took the shaft out of my old dizzy (has old/bad sensors) and swapped the OEM shaft into the new dizzy. now i got timing perfect with the dizzy right in the middle of the slot

thanks everyone for the help!!!

i’ve never had a boosted car before and wow it’s awesome haha

Ripper vids or pics?

How much power is your car supposed to be making?

don’t really know what you’re asking but i don’t have any pics of the dizzy swap

i’m shooting for the car to run very nicely as a daily, not too concerned about max power, but i think something like 280hp @10psi
