Hey man that is a great idea, but needs to be further tested?

I was under the impression that the Eclipse 420a PCM/ECUs where like this:
-1995- Totally different due to OBDI
-1996- First use of OBDII
-1997-Revides from 1996 model
-1998-9- The same little revisions from 97 model

Now the 95 is way different than the rest including pin count. I also though that all OBDII cars had the same pin count, but the 96 ECU had "internal differences". And I was told the Eclipse ECU doesn't advance timing at all or just a little bit. And I think part numbers on Avenger\Eclipse ECUs are the same.

So which ECU did you get? And I know sometimes I do things to me car expecting a gain, therefore i feel a gain, but actually there really isnt, kinda my brain tricking me into thinking there is one.
