ok doe sany body know if i can use my turboedit bass mapturned for a pr4 obd0 ls ecu in a 88-91 si ecu, help thanks

 

TE runs PM6 code. I'm surprised your basemap even works on OBD0 PR4... they are related hardware, but the PR4 running PM6-based code gets... wierd... sometimes.

Good luck running it on 88-89 PM6, BTW. Although possible with a daughterboard to fit an EPROM, there aren't any unless you make your own. Find 90-91 PM6 for teh win.
