DX ECU or Si ECU?

Ok, I have an HF car, with a DX motor, and I replaced the Dizzy with a 1.6L dizzy 'cause of the wiring harness (HF and Si the same, DX is different) The people that did my engine swap put in a supposed ZC computer and my car is running rich as shit, should I get a DX computer to match my motor? Or an Si computer to match the dizzy? I can't have an HF computer 'cause the damn rev limiter is too damn low.

Thanks!!

DX computer only works on DPFI cars so you can't use it if you have a ZC.

so get a PM6?

PM6 is the Si ecu, get the PM5 (the dx one)

that is assuming you dont have mpfi

yeah...we need some more info.. if its dpfi..I'm surprised if it would be running at all with a zc ecu..

Well he said he had an HF which is MPFI but with DX engine, so I assume they put the HF intake manifold and stuff on the DX engine which works fine as we all know. So in that case use an HF ECU or the Si PM6.

Yes, I have MPFI so I guess I will get the PM6
