I've done the MPFI swap on my 91 Civic Std and currently using a PM6 ECU...I want to try the PG7 from the old school Integra since I hear it's got a more agressive program as far as fuel and timing go.Anyone done this?I was just wondering if it's even worth doing.Only other mods are a Konig intake and Neuspeed wires.Thanks in advance!

 

i wouldn't use the PG7 on your D15B1. it will just run very very rich and stink out the tail pipe. a PM6 will run the engine rich as it is.

 

on my D16Z6 when i had the PM6 it ran ok and redlined @ 6800 when hot and 6400 on cold....

when i swapped for a 89 integra PG7 i noticced a whole diff world.... it redlines @ 7200 hot and 6500 cold.... and runs rich but hey its actually gives more power from 5500-7200 than the PM6

 

I'm interested too....

 

the pm6 rev limits at 7414 rpm. your timing must've been off or something.

 

My PM6 rev limit is at 7,000

 

your tach is off. JParker, otherwise known as the writer of TurboEDIT has told me many times that the rev limit of the pm6 is 7414 rpm. I belive him to be correct, seeing as how he has looked at the memory locations of pm6 ROM Dump to verify that information.

 

well i have come to beleive tha ti am also correct also
comparing the aftermarket tach , the vtec controller and dyno graps..... i have found out that the PM6 i had was 6800

 

no it wasnt.

 

I ran the pg7 on my a6. It was worth the rich smell because it offered more power and a wayyy higher redline. Worth it IMO.

 

dont use the pg7, no good, use pm6 (si) , mah will rev to 7300ish, then start poppin the redline.. but with ur std have u done the mpfi,wring,ecu,si agressive cam (a6), and 5 speed si tranny, the 4 speed will kill u, trust me, evan a dx 5 spd is better,

89 std hatch, jdm vti vtec/obd1,p28,h/i/e, and no tranny..help

 

my pm6 redlined at 6800. id like to see a video of a stock pm6 letting the engine rev up to 7414

 

an ECU doesnt red line. the tach red lines. the ECU rev limits, and it does so at 7414 rpm.

As i said, your tachs are off. You cant argue against the code hard coded into the ECU ROM.

 

The Honda tachs are NOTORIOUSLY inaccurate, especially at higher rpms. Being off 500 rpms off is not uncommon. Now aftermarket tachs are another matter...

 

Thanks for the input everyone...I don't really care to rev past 7000 with the stock rods,just looking for a little more low end as nothing really happens until about 4500 and not enough grip right now to do a swap .Honda Tech recently got 211 HP from a budget boosted D16A6,so I'm sure the D15 has potentional since it's got a shorter stroke.

 

rev limits are where you see em here "stk" means pm6

 

off topic anyone know the limit on a 1.5dx ecu

 

Around 6800....
