Im just wondering what you guys use to adjust your timing and fuel when you turbo. Like do you put a stand alone in, do you use stock ECU with adds. What do you use, etc.

Id appreciate any info I can get, Thank you

 

I repinned my car for use with the 59 code from http://www.code59.org using a GM 730 ECM. Basically converted the car over to the 91-92 SD system with a few more pin changes and new code.

BTW wideband O2 is a must!

 

i run the same thing on my turbo car. a 730 ecm with the code59 def file installed in it. It is good up to 30 lbs of boost. so far working but not as easy as 8d which i am used to tuning and ee lt1 stuff but it is working . and tony89gta i have the new afr eliminator heads on mine and they are sweet. I had a old set of afr 190s on my lt1 and these are so much better especially the new ls1 style valve guide size and small springs they use. I got the ported ones and flow right at 300 cfm at 650 lift.

 

I'm using a stand alone - the Holley commander 950 ecu. It's very user friendly and changing the fuel and timing tables are easy. The hard part is finding what your engine wants.

 

Ah sweet your using the competition heads, wish they had that when I ordered mine
