OR...you could just install the EBL Flash II with a stock 82/84 tune that runs perfect. If you decide to mod your 84 down the road, you can change the tune. 100% laptop tunable.

Buc,
How does that EBL work? Does someone send a 84 ECM to the shop to get tuned then plug-n-play on return?

I'm not in the know but wonder if bobR does the EBL modifications to the 1226026 ECM. If he does, it's like turning the remove, erase, write and replace PROM into a flash tune ECM. If bobR doesn't, then you would probably need to use a '7747 ECM EBL modded with the mentioned ^^^home made adapter harness. Not sure if they're available but I remember someone mentioning a ham board that would make the '7747 plug and play. Anyhoo...yeah it would be as simple as flashing the stock tune to EBL. Below sample of 1226026 card connector end followed by 1227747 pin connector...

Bob installs a ham board into one of his modded ECMs. At least that's what was done to mine. Not sure if Buccaneer orders and has someone else install or if Bob does it then sends it to him. Either way it is a 7747 or similar with bobs modification. For a non stock application its a great piece and easier to work with than the burn replace or an emulator...

Yes, I send my newest Rev (D) HAM boards directly to Dynamic EFI for installation into the EBL. I exclusively use Dynamic EFI to install the HAM boards into their ECM. It is the best thing going for the CFI crowd unless you want to move to something more exotic like a HalTech for a lot more money and harness plug conversions needed. The EBL is 100% plug-n-play for CFI and comes with a stock 82/84 CF tune preinstalled from me by Dynamic EFI which I think is better than the GM stock tune and is not on the hairy edge, but not as conservative as GM tune. I even had a Chevrolet dealership in MO install the EBL in a customers 82 and they called me and said they were impressed with the tune, it fired right up, idled fine and ran like a dream. What else can you ask for in a stock tune for a 40 year old car? I do get a lot of after the EBL sales calls from satisfied customers.
In a time when a stock 82/84 GM ECM is harder to find a working ECM than hens teeth, the EBL is hands down a great product. Why would you want a stock ECM anyway? Since it is 100% laptop tunable, you can make any modification down the road to your motor that you want and the EBL will handle it to include spray. We do not lock the stock tune in any way and is a great base tune for mods. I wish this was available back when I bought my 82, 30 years ago. I hope this helps a bit.

Is the original harness ECM plug for the CFI altered in anyway? So, basically, can the system be converted back to original, if desired?
YES, 100% plug-n-play, NO MODS required. Even have a bib for stock 4+3.
Cool. I am considering this upgrade for my 37K miles 82CE. While it is running great right now on an 84 ECM, this could tweak it. Website to get pricing, etc?
Curious to see someone take this to the next level after converting to '7747, repin to a truck PCM '7427 and perhaps have it control a 4L60E...but that's not the only benefit. '7747 spits out data point once every 2 seconds but going to a '7427, spits it out 50x faster and tuning gets done hella faster!!!
@stew86MCSS396 I have done this. My 84 has been running a '8625 truck PCM since 2004 and last month I finally swapped the old 700r4 for a 4L60e. It's soooo much nicer than the clunky old 27 spline 700r4 with no aux valve body etc etc..
To address the original poster's question, as other have suggested - EBL all the way!

Nice!!! I already saw you posting on another site that you've already done it. You running $E6 mask with that PCM? Was helping a friend on his truck and the ADX for $E6 was very glitchy. Was only able to drive around the block for a few minutes and it would freeze up. Changed it up to $0D.ADX and no glitchy datalogs. Oh did you also add the fan hack since our C4s do use electric fan(s)???
It would seem anyone that made the leap from '7747 to '7427, has said the engine seemed to run a whole better without jumping into the tune. I wonder if it's just the mere fact that the faster 160 baud vs. 8192 baud rate helps smooths things out a lot quicker. My understanding is that with EBL, it does put out data at the higher rate meaning it does speed things up like the faster ECM/PCMs.
Yeah I've been running $E6 since ~2004 without any problems.
I think I was one of the first to do this and I had to make my own definition files for TunerPro etc.
Once it became more popular everyone was using $0D but because I already had so many hours into my $E6 definition and tune I couldn't see any reason to start all over again for very little gain.
I haven't done the fan hack, but I do have WBo2 0-5v coming in on the EGR Pintle Position input and rescaled via a lookup table for datalogging.
I have an occasional datalogging dropout. It used to be terrible, but a more expensive properly shielded USB cable fixed that and it's barely an issue now.
