I've had my turbo swap running for a while, but there have been issues. I have narrowed it down to the injectors, but upon second thought of what injectors I need to buy (high imp. i know) to replace the bad ones, my thoughts came to my ECU.

I have an N332 ECU (87 TII ECU) and an 88 harness and injectors, is this a problem to do this? Do I need to have the 88 ECU? Or am I ok?

It's been running this for about a month but with slight issues with actual flooding/bogging at 1-2psi of boost at 4700rpms, and it's really bad at 4000rpms at anything over 1psi. It's like the turbo will spool, heard and felt, but then the pressure built up dies/stalls the turbo. The motor will still be running but just bogs like its flooded.
I'm kicking myself for buying Crown Vic 1680cc's for the secondaries. This is what I believe is the problem. TELL ME I'M CORRECT IN THIS ASSUMPTION. I really don't want to have to buy another ECU and have it modded for the Rtech1.7. I know I know, i should have bought good injectors.

It was dumb, but live, learn, boost.

Thanks for the help.

No. The N332 should work as long as the injectors are the high impedence ones.

FYI...On occasion I run a N333 (88 ECU) on my 87turbo car. The ECU just needs to see a given resistance/impedence from the injector circuit. On the early 87's that is done by using a solenoid resistor package. On later 87 cars and on, that is done by the injectors themselves. The early 87's injectors were about 2-3 ohms by themselves. The later cars injectors are around 12ohms.

Bottom line is the N332 should work in the 88 car.

OH! I see said the blind man. You have Large *** injectors in the secondays. That IS your problem. Too much fuel just bogging the heck out of the engine.

Secondarys come online when the engine speed is over 3800rpm AND there is a load on the engine. Matter of fact, the LOAD is virtually at 0 boost and up. In other words, once the engine isn't pulling vacuum, that constitutes LOAD. In practical terms anyway.

Too much, too big of secondary injectors.
