Do you have to perform modifications to or change the computer when you put a different set of heads and put a different cam in the 93 LT-1's?

You would need a new "tune".... and in the 93's that means you would have to have a new plug-in chip made.Fred
381ci all-forged stroker - 10.8:1 - CNC LT4 heads/intake - CC solid roller - MoTeC engine management - 8 LS1 coils - 58mm TB - 78# injectors - 300-shot dry nitrous - TH400 - Gear Vendor O/D - Strange 12-bolt - 4.11's - AS&M headers - duals - Corbeau seat - AutoMeter gauges - roll bar - Spohn suspension - QA1 shocks - a few other odds 'n ends. 800HP/800lb-ft at the flywheel, on a 300-shot. 11.5 @ 117MPH straight motor -
ECM
So I have tp go somewhere and pay some guy a load of cash to have one custom made? Or is there some that is already made?Comment

Depends on how radical the heads/cam are. There are "mail order" tuners.... they send you a questionaire to identify the specifics of your engine, then burn a chip and send it to you. If you are using some relatively common items, they will get it reasonably close.
If you are into "programming" you can buy a chip burner and software to burn your own.Fred

okay, I am doing a TPI conversion in my car (look in the sig), and am going to buy all the stuff to burn my own chips. Will almost the same stuff work for my '93 ECM?Originally posted by Injuneer
