Help distributor advance?
Hello where can I find the stock settings for the distributor advance curve for a 1989 305 chevy 1500 TBI automatic trans pickup?
I put this fuel injection system in my IHscout 304v8 and the curve seems to max out too soon at around 2000 rpm. So I need the stock Chevy specs.!!!!!
THis is what I found
* this is with the wire for timing disconnected!
-1000rpm= 7
-1500rpm= 17
-2000rpm= 21
-2500rpm= 22
-3000rpm= 22
Thanks,
Brandon

First this forum is for 3rd gen fbodies.
Second, the TBI motor's ignition curve is handles completely by the computer. Nothing you can change without getting a custom chip. And having the total timing in by 2000 isnt bad either.
