Sound like an ECU issue???

[Cinciguy90Turbo]

So my friend wrecks my 89 turbo with 89 turbo motor. I found a 90 N/A body to put my 89 turbo motor in. Got into the swap and of course there is an ECU and harness difference. Looked on here and found a 92 turbo ECU and put it in the car. The car idles, and drives fine. When I get on it it seems to bog down and doesn't wanna accelerate really at all. Before the swap of course it ran like a scalled dog!
Can anyone help me with this? I know there are a million posts about the ECU/Harness issue but this has a little twist because the car is now not running properly. I feel that the ECU isn't mixing the right amount of fuel to air it backfired pretty bad one time.


Thanks for any help anyone can give me its greatly appreciated!
