Default 86 C4 computer upgrade?

I have looked at a ton of sites and I can't find any ecu upgrades for my 86 auto. Does anyone know of a few that I could check out?

I don't know of any upgraded ECMs, but if you are looking to tune current ECM, check Moates.net.

I think that the only ecm's that people really upgrade from are 84-85. 86-up are all good ones

What are you trying to achieve?
Plenty of aftermarket stuff out there but $1500+ starting price.
Some upgrade to the 90-91 "730/ 727 " MAP setup for tuning purposes.
