Just a quick update.  Eric from Parts never followed through.  I've given up.  Now I have an ECU problem!  No one programs them anymore.

John, there are used Z parts sources, and they're well worth checking.   ECUs also are available, and it's more practical to replace than to try and re-program.

Thanks Pilgrim.  I've researched several sources (e.g, Jim Wolf, Z Car Source), but my problem is I have a rising rate fuel regulator plus a lot of other upgrades such as Turbonetics T3/T04B Hybrid Turbocharger, Intercooler, Adjustable Boost, Cold Air Induction, Limited Slip Differential, No Catalytic Converter, and Performance Exhaust.  The people I've contacted say their standard ECU's likely won't work with the rising rate fuel regulator as the ECU's only work with 1:1 ratio.  Not sure what I'm going to do except keep researching.  

If you have lots of mods the stock ECU won't work. You will have to move to an aftermarket EFI system

Thanks Patcon.  Do you have an aftermarket recommendation?  

Depends how DIY you want to be.

Mega squirt being the most DIY

Several guys here on the forum are going Haltech

Haven't laid hands on either

 

Thanks for the info
