I know I'm probably the last guy on the planet running these engines, but does anyone have a line on the ECM for one of these dinosaurs ? I've got one that I believe is in limp mode. All the sensors check out fine, (BIG THANKS TO CUDA! for the TPS), but it will not idle below 1000 rpm when out of enrichment(cold) mode and the power is down vs starboard side. Everything is new and functioning properly IE; injectors, fuel pressure regulator, entire engine for that matter which is built exactly the same as the other.
I think I see new intakes and carbs in my future

A buddy of mine has a pair of 320 EFI's and he's got a bunch of spare parts. I'll check with him tonight.

What does the ECM look like? Maybe I missed something when filling the box. I'm pretty sure I had everything when I got the engine.

Biggus- thanks for checking
Cuda- Thanks again for the TPS- the ECM is a black box about 10''x5'' it has 3 mounting ears, and a 12 pin female connector for the wiring, and lets not forget the 5/16 hose for the map sensor.

Has the TPS voltage been set to spec?

Sorry Sonic, my buddy does have a spare ECU but he wants to hang on to it.

Kurt.

Stingray- the only adjustment is the resistance 50-100 ohms @ idle which is [email protected] TPS was bad on startup and Cuda sent me one that works so I've eliminated that.

Biggus- thanks for checking I don't blame your buddy one bit, I'd hang on to the parts too!

I think I had that part. Is is silver and red with some writing on it?

I was just rumaging around in my garage looking for a voltage tester, and I ran across this on top of the fridge in the garage. I told Debbie I'm about to make someone very happy!

Send me your address again, and I'll get it out tomorrow. Sorry, I thought I had everything in the box.
