Hey, no cold start injector?? Awesome idea! I'd LOVE to see this turned into a "kit" as well. For those of us with practically zero car computer experience.

Ryan, have you got any experience with flex fuel ECM's? I'm wondering what automakers are using these days. I know GM uses a fuel composition sensor too.

I say post away on the wiring pin out and instructions. Also post what parts are used and from what cars...

I would consider purchasing a kit for my 1986 2.8 with 4-speed that has the updated ECM , EGR bracket, pins and connectors with a project instruction manual with exact part numbers for the EGR and knock sensor.
Sure like the idea of improved performance from the cold idle stand point. This sounds like once you have it all installed that you would never have to fuss with again. 
Ryan, has your customers gas mileage and or emissions improved? Any comments from your customer that you can pass along to us please?
Outstanding post!

The owner picked up the car and drove it straight home to Michigan and put it into storage until spring. He did call and tell me that, according to his digital fuel gauge and mileage calculations, he got 35 mpg on the trip. Remember, that's using the 4-speed auto OD trans making the engine only turn about 2200rpm @ 70mph. So it's hard to say whether or not the ECM swap contributed to increased fuel economy or not. I can tell you that the 7730 running the $88 code mask DOES have highway mode fuel (lean cruise).

The one I had made looks similar to that but I don't think they are the same. The one you have pictured appears to be meant for use only on 3100 and 3400 engines and doesn't mention anything about using a stock Fiero Y-pipe. The adapter I designed and had made bolts tot he stock Fiero EGR block/y-pipe and allows a digital EGR to be bolted onto it.

I see. Just thought I'd ask in case it would work for someone looking to do this right away.

Forget it, dude. You even look at the emissions system on an California car wrong and you'll fail smog. Much as this upgrade would probably help emissions, it'll never fly in this state.

I was wondering. What would be a cost estimate of this upgrade. Even better would be a parts/supplies list with estimated prices off to the side. Also, Darth, would you be willing to modify a 7730 with the necessary wires & connectors (with extra long wiring to cut to fit) if I sent one to you and how much would you charge. Also, each time I upgrade my engine, how do I modify the ECM software or do I need to send it back to you. If I do need to send it back to you for reprogramming, what info would you need to properly tune it. Oh yeah...how much besides shipping would you charge for reprogramming each time?
