the afc says 6900, i dont really want to go that high but i was wondering why it redlines at 6900 instead of the 7500 that its suppose to be at

 

the 88-89 Integra ECU (PG7)
are supposed to redline @ 7200

I use the PG7. Its redline is 7200RPM

 

7200 should be the cutoff

 

One of my friends had a zc in his 91 si and he had this ecu. When the car was cold it would redline at 6900 but would wrap up to 7800 when it warmed up.

 

Ths is what happens to a D series when you rev it past 7800 with stock internals

 

i have a zc ecu if you want it. 100 bucks

 

 

mines redlined to 7200 also, if u want a pg7 i have one for sale 60shipped, i revved my d16a6 to 8000 and that didnt happend..

 

This was reved up to 9000RPM on a chiped ECU. We blew it up on purpose before we did the swap. The cam nearly welded its self to the head.

 

<U></U> yep

 

is there something wrong with the ecu cause it use to rev up to 7500 when i had camshafts and only when i was at the track. is it stuck on cold mode or something?

 

89 Integra ECU, should be PG7 correct? I believe the actual fuel cutoff on that is at 7800 because I have it on a ZC and I shift at 7200 with no fuel cut at all. The PM6 however, has redlines at 6800 on the tach and fuel cuts around 7200.
