DOHC ZC: PG7 or PM7?

i want to swap my ecu from my stock si. I heard the PG7 is better cause it has no speed govenor and also the PM7 is hard to find. Anyone who has any of these in their dohc zc's i'd like to hear what you think. Thanks

Pm7!! Ecu made for ZC Dohc. i have got Pg7 on mine for now and runs good. Pm7 just a little harder to find as you mentioned. however runs a little richer and less MPG :disappoin but cant have everything. Or you can always get Pm6 chipped with ZC Maps and no speed gov. Just make sure to change back to Pm6 if gonna go get smogged. i would go with Pm7 if i were you and if you cant get your hands on 1, go with pg7 works just fine. just my :2cents:

yeah i got a few buddies runnin pg7's with there dohc zc's and claim they pull harder..but the mixture is a lil rich.. but hey rich is better then lean ;)

Hey thanks man..really appreciate it. I think i'm gonna go for the pg7..seems to pull harder so i hear. Are ecu's easy to remove/replace? Is it bassicly just plug in plug out sorta thing? I've never done any ecu work before so this will be a first..thanks

yeah removing/installing the ecu is cake.. just lift the carpet up at the front passenger area where u rest ur feet and u will see a copper coated plate..undo the 4 nuts and voila it pops off and then u got just 3 plugs to remove..just be easy when messin with the plugs cause i realized some civics have not a hair of slack on them and when moving them around u could accidentally pull a wire n shit. g/l dude oh yeaqh i forgot to meantion if my memory serves me right that the pg7 got a extra mounting bracket so the ecu might not bolt down right but the plate will still bolt down which will still keep the ecu nice n snug. no biggie

yeah PG7 doesnt bolt right up. What i did was put PG7 into PM6 case. fits perfect with only 1 problem. LED on PG7 is down on bottom and PM6 case has hole to view codes higher up.Not a problem unless your going to check for codes. you could just drill a small hole in case to view LED.Or you could just bolt plate down to hold it in place as mentioned by 91 Civic 1.5 HB. All up to you. Either way is very easy.GL though and PG7 pulls way harder than PM6 and you'll love it!!

thanks a lot guys..that helped me out a lot. I'll probably hit up a junkyard in the next few weeks and plug that baby in. I'll let you guys know how it turns out. Thanks again. peace
