Just a quick post. The Dynamic EFI products use a stock GM ECM. However, there is better firmware, data logging, and analysis features. If you want or need OEM capability to pass smog, or just want a great upgrade to a factory ECM check out the EBL Flash and EBL Flash P4 systems.
No chip buring or swapping, flash in a new calibration (within seconds) via the same data cable as is used to log and view the engine data.

Huge fan, sure is easy to use :thumbsup:

Ditto :D I'm running it on a 9.5:1 383 with Vortec heads, 454 throttle body and Comp 08-412-8 cam. 13,000 or so miles and no issues :)
I've recently upgraded to PCM 16197427 (TBI) and have installed a 4L80E. The next project is to install a supercharger with TBI. Which system; EBL Flash or EBL Flash P4 is recommended to that allows PCM 16197427 to operate boost and the 4L80E?Quote:

To do this another set of ECM harness connectors get added to the stock harness. Then the engine control wires are moved from the stock PCM harness connectors to the new connectors.
We have the re-pin information along with the additional connectors to do this.

Dang it:mad1: that's not the news / information I was hoping for. I think I might try going with the '0411 PCM (if I can figure out how to run TBI with the '0411), seeing how I'm not liking the idea of two computers.

Doesn't sound that bad Dave! 2 ECM stack easy and RBob has it dialed in!
RBob I had read a rumor of a new EBL with trans controls for this type situation. Any truth to that becoming a reality?
It is what we want to do next.Quote:

I will simply state, I would be customer of a '427 based product that allows full functionally of either the 4L60E / 4L80E and full functionally of EBL Flash / EBL Flash P4 in one computer! I'm really liking the idea that I could use jumpers to operate TBI / Dual TBI / TPI / MPFI with or without Boost with the factory knock filter! I know, I'm asking for tooooooooo much in one product?:homer:Quote:

I don't even need the TIS input with $0d_maf for tranny VSS (MAF needs that VSS pin), I just patched the bin to use the regular VSS input in the tranny code (it works fine).
I should probably consolidate all my 7427 patches onto this site and maybe delcohacking... one of these days =).
Now, where it's really at is CNP support. You could put eDist out of business by doing proper dwell calculations. Doing this on the stock 7427 hardware is no small hack, but it is "possible" if you re-purpose the tranny pins and write the code. I've looked into it, there is an available interrupt with unused pin for 1x cam signal (certain 4cylinder applications). But, then I'd also want to support LSx motors and a 24x CKP signal is probably too much for our beloved 2mhz chip to handle.
0411 would need hardware & software hacking to run TBI (injector drivers)...
RBob, are you hiring..? =). I'll email you one of these days..
