Yes it works fine. Ask my car. 90 SI with an LS swap.

Damn that must be nice. "Car, how's your oil doing?" "It has a few hundred mile left, as long as you stop beating me like your dick".

Lol...nice. A Pr4 would be your better option than trying to chip a pm6 with the LS map. I'm not saying it wouldn't run, but from my understanding (from things strewn across pgmfi) the pr4 has 3 map sets( I think it's something to do with fuel economy in open loop...it's non-editable), whereas the pm6 only has 2(closed loop, open loop)...I think xenocron can verify this if I'm wrong...it's been a long day and I'm exhausted :P

Either chip your existing PM6 with LS maps, or get OBD1/2 LS distributor, OBD0-1 conversion harness, and OBD1 ECU. Which way depends on what you want to do - keep reading, kid.

Firstly, I was the one pointed out the three OBD0 PR4 maps IIRC, and I just used the ones that looked most like OBD1 maps. The rest of the maps are largely irrelevant as 90-91 DA is a sack of ---- emissions and useless actuator-wise. The ECU code and control scheme is a pig pile. :3

Secondly, OBD0 PR4 ECU aren't very compatible with TurboEdit for low power turbo setups

Third, when really large injectors of power levels are the intention, you really can't beat OBD1 code as it's more fully developed and has cold enrichment tweaks.

Thanks for clearing that up JD. I knew I read it from somebody, just couldn't remember who.
