New 383 SBC GEN I engine build. When to switch out ECM.
I have a '86 IROC stock 305TPI and own the Moates' APU1 AutoProm which has the ability to change the values in the tables with the engine running in realtime.
Second, I'm slowly building up a 383 EFI engine build where I wanted to use the original 1227165 ECM. It's almost complete, but I need to save for cylinder heads... Anyway, around this same time I started looking at the EBL P4. I recently read that it doesn't do realtime PROM Emulation? Which is sorta discouraging me from the EBL. Anyway, that was one issue, but not why I posted but feel free to comment on that.
To me it would seem logical to do the 1227730 ECM conversion first and get the 1986 OEM 305TPI working with the MAP sensor, lose the MAF and do the work for the changeover to the 350 90-92 camaro knock sensors.
Am I on the right track?

Eh its up to you. How wild is the new 383? Stock maf gutted screens will support decent hp. It will max out early but the 165 has pe mode vs rpm to handle the fuel
Ebl is nice for not having to burn chips which can be pita. Dont need real time emulation to tune but it kinda would be easier to change things on the fly.

Regarding EBL vs. Moates AutoProm: I would've thought the Moates' unit would be superior since you can change settings in real-time, till you find optimum engine running conditions, then burn a prom as a last step.

I have the EBL and can tell you that its awesome. I have never tried tuning on the fly. I drive the car. Pull over on the side of the road, make my adjustments (assuming its something quick and simple I'm changing)..reflash the pcm (takes about 3 seconds) and I'm off again. No chips to burn... at all.... ever....
Hoever, I did ask RBob if tuning can be done with the car running and he said it could. I don't remember the details and have never done it, but I do remember that it can be done. You might PM him to get the details.

Thanks for your input guys, but I sorta went off on a tangent talking about the programmer options. Honestly, I would've gone with the EBL P4 if I didn't already own the Moates Autoprom. The EBL seems to have great support here! I may still get it based on some special 'added' features like reaching up into the 6K RPM range. But I'm new in this arena, so that's why I'm posting here, in order to plan for the future.
In the original post I mentioned why I really started this thread. I think I need to loose the original MAF based ECU (1227165) and get a 3-bar MAP sensor and a PCM (1227730 from 90-92 Camaro) that can handle that.

You can tune EBL with the motor running but it will go into limp mode for a couple of seconds while you load it. But what works really well is you can load eight bin files into it and switch between them instantly. I had an off idle stumble so i loaded files with -1, -2, -3, +1, +2, +3 degrees timing at that point and switched back and forth till I found the best one.

If I can sell my Autoprom, I'll be getting the EBL installed on a 730 ecm. Thanks for the info.
