is there a difference i have a 90 integra pr4 ecu and it revs to 6800rpm but i think the 91 ecu revs to 7200rpm any info would be awesome

 

The only difference between the 90 PR4 (PR4-A01, A02, L01, L02) integra ECU and the 91 PR4 (PR4-A10, A60, L10, L60) is that the 90 version has an external PA sensor and the 91 version has an internal PA sensor.

Rev limits would be the same...

HTH

 

Good info, i learned something new

 

are you sure cuz my ecu revs to 6800 and my boys 91 cpu revs to 7200 can that be explained

 

morning bump

my '91 only revs to 6800 in stock form so maybe your 'boys' ecu is chipped with one of those lovely Ebay programs out there
