Thanx guys, I'm going to set it to 10 for right now as I am haveing problems but I remember hearing that running it at 12 is better so I'll change it once I work out the bugs. Thanx again

Re: Injection timing for a 1990 camaro RS V6
yeah, 10* is stock for all 2.8L and 3.1L engines, but most people run at 12* or 13* for a tiny bit of power and fuel economy. I personally run 15* and hdo not have a problem with detonation.

Re: Injection timing for a 1990 camaro RS V6
2.8 u sure on that, i remeber my old sticker on my stock hood saying 12* on my 2.8, but i no longer have the stock hood to look again. i will dbl check nextime in in the jy though they have a boatload of v6 f-bodys and even 2 iron duke f-bodys
everytime i go i always have to fight the urge to go ask how much for one of the iron duke cars as there all there but one has a blown motor and one has a bad trans.
could be an interesting lil turbo 4 banger project

Re: Injection timing for a 1990 camaro RS V6
this may be a dumb question but... how do you change your timing? I've never attempted it... also, won't the ecm just put it back to stock?

Re: Injection timing for a 1990 camaro RS V6
u can set the base timming, so say u advance the base 2* it will always be 2 more then the ecm would normally have int he motor same if u pull it out.
u start the car and let it warm up, then u unplug the est connector and use a timing light like u would any othe rmotor and rotate the dizzy
