69 Camaro EFI Problems

Hello All,

So on the latest edition of my quest for horsepower, I bought the GMPP 502 Ram Jet for my 69 Camaro (Rockcrusher 4 Speed). I bought the engine second hand and was given Accel ECM, Wire Harness, etc..which has become a problem. No one I know of in my area knows how to tune the Accel stuff (2000-2003 I believe). Does anyone know how to tune this stuff, know of someone who can in California, or has a better suggestion (such as a cheap MEFI-4 system). At any rate, the reason this is a problem is because first and second are currently not streetable. It's loping forward so hard that it feels as though I'm offroading and the throttle response is just not there. I either minimally press it and it makes my car basically bounce, or I press the gas a little more and I'm going 60. I need some control and for this engine to be more streetable. PLEASE HELP!

Check with accel dfi to see if they have a list of tuners. Those guys should be easy to find in Cali. When in doubt call the nearest speed shop and see who they recommend

One last thought....did the engine get modified with a different cam?

Re: 69 Camaro EFI Problems

I have a POWERJECTION III on my 69 Camaro with small block 350. I have had nothing but problems with it. I cannot get the car to turn over. I have fuel pressure, the pump in running, but I am not getting any fuel spraying into the curb - thus not starting~ I re-hooked the computer program back up -- the computer over rode the system and the car started (for 3 mins-hicupping until it died) and it wouldn't start back up. Back to square 1 No fuel spray in the curb, but fuel pump running and plenty of pressure at the source? Any ideas? has this happened to anybody else? Trouble shooting thoughts? Thank you! T.J.
