dpfi pm5 ecs are not user friendly. Thy have some very loose support.

You have to reg

I would swap to a a6 intake or z6 intake, convert your harness to mpfi, get a mpfi obdo distributor, get a chipped pm6,pr4,ps9 and run turbo edit. To make any sort of useful progress.

Also are we talking us pm5 I have read about a mpfi jdm pm5 that can be chiped?

if i get a pm6 will it plug directly in? i found a pm6 for cheap but what other wiring must be done? i have a d15b2 wire harness converted to mpfi, will that plug directly in to the pm6?

Google the mpfi swap. The pm6 you will find comes with the same ecm connectors. Do the swap & go to fry's electronics and buy a .69$ 28 pin socket then solder it in. Then run whatever map you choose. The whole thing is your best bet if you want to start tuning.
