Moving forward again, when I did the dyno tuning I didn't have ecucontrol working... however, I will be going to the dyno again to give it a whirl. Something that may be of interest to this community is this:
http://support.moates.net/2009/02/05/unsupported-honda-configurations/" 1988-1989 Civic Si (PM6) and 1988-1991 CRX HF ECU (PM8) require a daughterboard we do not sell in order to be chipped. Use a 90-91 ECU on these model years. "
This may be described in a previous thread somewhere but I've just been doing some research and muddling around the internets... I then email Moates about this asking how do we identify the two...
his response was:
"90-91 ECUs have an Oki 38256 EPROM present from the factory. 88-89 ECUs do not. If you have a 28 pin EPROM, you're good to go. If not, none of the hardware we sell will work."
Good answer but still doesn't answer my original question. After looking at tons of ecu's, apparently there is a blue stamp to the left of the ecu identification sticker that denotes the year... as far as I have found out:
88 - no go
89 - maybe (depends when in the year it was made)
90/91 - of course
Looking even further I notice that the older ecu's don't have chipset IC19 (and if they do, omg where the hell is it)..
hope the helps some.. b/c it's taken awhile to find this stuff.
cheers,
