Chipping question

Well, I have a PM6 ECU that i would like to chip. And i read from PGMFI.org that you have to change couple of capacitors? Is this true? I'm totally confused? I thought I only have to replace the 28 pin chip only?

This is correct.

It would help if you gave us a link to the info that was confusing you...my bet is you were reading about OBD1 chipping.

Re:Chipping question

Does PR4's require more than the basic OBD0 chipping?? Like does it need additional capacitors? Etc???

Re:Chipping question

No, obd0 PR4's and PM6's both just need a socket, unless you want datalogging too. If so, you have to solder in 4 pin headers to the CN2/CN3 connectors as well. (that's how I do it anyway)

there's 5 points at cn2/3, you only use 1,2, and 4 with a nokia cable, and 1-4 with a max 233

yeah, I just put pin headers on 1-4 and leave out 3 on the connector plug if using the cable. That way, if I need the 5v, it's there.

Re:Chipping question

thanks for the response guys... So OBD1 ECU needs extra parts?
