I am a newbie who tried to find the rev limit for a PM7 in the forum and wiki but did not see it (probably should have looked through again).

Had a play with my PM7-000 ecu ROM and found the rev limit is at address 0EB2h (using the 16bit OBD0 formula)



Great website guys, keep up the good work!

Hi,

I was just using winhex to find where the revlimit was in my PM7 ecu. I tried using turboedit to alter the maps, which did work, but did not have a go at datalogging and editing online.

I did not do too much more with the PM7 as I have changed to a B20 vtec engine and PW0-000 computer that I took to the dyno shop and tuned using Ben Ogles rom editor and ostrich from craig moates (which work exceptionally well).

The NG55/NG60 roms are not ones I have played with. I think they are for the PM6/PM7 ecu's and have been modified to give extra tables for boost pressures on the MAP sensor. I think that Ben Ogles editor (BRE) supports them so if you are doing a turbo setup, try that.
