ok
i am running a PM6 CRX Si ecu on my Z6 engine
since i got it it redlines @ 6800 when hot and 6400 when cold
i know the cold rev limiter to protect the engine
but why is it redlining at 6800?? its supposed to be 7200 hot and 6800 cold....
does any other Pm6's of u guys does the same thing??
i kinda hate shifting @ 6600 when i feel i can go a little more...
i am also thinking of just getting a 88-89 PG7 so i get a better fuel map and a higher rpm redline (7800) if i am not mistaken........ any input will be aprreciated...

 

mine kills at 6500 no matter what... figure that out

 

to the

 

The SI computer's rev limit is 6500. The 7200 rev limit your thinking of is from the 88-89 integra computer. unless your computer is chipped it never reached past 6500.

 

i know what u trying to say
but the 4G Si the redline its supposed to be 7200... and yes fuel cutoff its supposed to be before.... the 88-89 PG7 its even higher than the Si and has a better fuel map.... i met a guy on the track with a stock PG7 off a 89 teg and it redlines @ 7600....
and yes my ecu redlines @ 6800...... and 6400 when cold...... its not a fast tach... its bc i have taken it slowly over to that rpms... just wondering why will it redline that low...... if it was normal......

 

I belive the 88-89 PM6 is different than the 90-91. The 88 only revs to 6500, the 90-91 goes to 7200. The 8889 PG7 goes to about 6800 to 7200 but i've taken mine too past 7600. Hmm i duno if that was any help, but there u go anyway.

 

Ive got a good pm6 for sale if anyone needs it

 

wanna trade me for my PM6 so i can rev past 6800!? )

 

Convert to OBD-I, then you can rev to 7500 before you hit any limit.

 

mine is froma 91 crx and it cutsoff at 7200 it didnt have that before i changed teh thermostat it would cutoff early cause it wasnt warming up right

 

mines form a 91 hatch si kills at 6500 when i miss shift i can get it to hit 7500 but thats after a min and a half of fuel kill

My 88 PM6 cut at 6500. I always heard it was higher but I guess it was different years. Got LS now so it don't matter.
