I Just bought a ECM For a 1989 Caprice 350 TBI, I am going to Hook it to My 1988 Camaro L03 which has a L05 Motor. I also bought new 350 Fuel Injectors. Is there anything else I need to get my camaro Converted to a 350? And the Big Question.. Will I notice any diffrence? The car Pulls pretty good as it is now... Will it pull even Harder after I hook this stuff on? I just spent 360 Bucks on those two things. Sheesh!

 

Well, I'll Try it at the Track this weekend.. see what diffrences appear..

 

I don't believe the '89 Caprice had VATs, but you may want to try the ECM before going to the track. Just in case it does. If it does the injectors won't fire.

You should be able to run the 350 injectors with the LO3 ECM. The BPC is a ratio of displacement to injector flow. The displacment has been increased, putting in the larger injectors will bring the BPC ratio back in line.

So I dont need to Swap the ECM? I have the Stock 1988 L03 ECM. The ONE year ECM. I have the Computer But NO prom so i have to take the L03 ECM Prom and put it in the 350 caprice ECM, Is that a waste of time? I get the Injectors Friday.
