Hello to all the CFI owners. UPDATE! I was notified a week ago that Dynamic EFI will no longer be installing my interface board in the EBL ECMs for CFI. I think Bob at Dynamic EFI is going to be retiring. This is a HUGE problem for all the 82/84 Corvette owners and the 82/83 Camaro, Firebird and Trans Am owners that will need ECMs. I'm trying to work something out to continue to provide ECMs to the CFI community, but I may fail. If so, there will not be ANY ECMs available of the face on the planet that will be worth a %$^#. Just letting everyone know what's going on in the CFI world before it becomes a crisis. GL all.

 

This is very, very sad news. I have forwarded it to my community to perhaps encourage someone who is undecided to get one of your ECMs. I am happy to already own an EBL ECM and do not regret the purchase in any way, even more so now.

 

This is not good news. Keeping fingers crossed you get something figured out since if it wasn't for you there wouldn't be as many CFI's still working today.

 

please keep all us cfi owners informed i was waiting till next year to get one

 

Thank you to all and hope I can work something out, but a little doubtful at the moment. I can not call Bob anymore since he disconnected his landline due to non-stop junk calls. Now, it's only email which I absolutely hate and makes my life a lot harder. I'm actually thinking about flying out there and doing a face-to-face meeting with Bob. I'll see how that works out. This whole thing affects a lot of other things as well.

 

No news yet.

 

My ECM finally gave out, and I was about to hash out the cash to buy one of the Dynamic ECMs for my 82 only to realize I’m too late..

Are you are the one who makes the HAM interface boards?
Why not just sell the boards with instructions on how to install them on a specific ECM?


Hell I’d be satisfied with a wiring diagram for the specific ECMs that you guys used, to see which pins I have to connect to the OEM harness. Which ECM was the one compatible with the ham board? I could flash it myself and hardwire it if I get desperate.
most likely just splice on another harness on both ends.

 

No, I do not sell my HAM board anymore, too much BS that goes with that type of sale. Also, it doesn't make any sense to install the HAM board without the EBL board installed as well and that's the real problem right now. On top of that and to make matters worse, Bob at Dynamic EFI has been ghosting me for two weeks now with two emails. Something VERY odd is going on over there and I have no clue why. Actually no, you can't flash anything without the EBL installed, it doesn't work that way and I wish it was that easy.

 

Hopefully someone will step up. There are still some good electronics hobby guys out there. Or worst case, if the community came together, maybe there's an industrious Chinese or Indian outfit that can make a whole bunch of boards. Don't want to say that, but if it comes to it. Get them stuffed locally. They can literally do stuff in a few weeks (and a fraction of the cost). But hopefully someone in the community will fill the void. Keep us up to speed.

 

You can always grab a ECM and it's pigtail connectors from any late 80's early 90's 305, 350 TBI Chevy or GMC truck and wire it in. If you don't care about originality, I would look for some other induction system. The Crossfire wasn't exactly GM's finest piece of engineering.

 

I'm working with a local engineering company at the moment and meeting with them next week and their engineering department to see what I can work out. I'm so tired of depending on other companies on certain things. I have a huge backlog of EBL customers right now and it's pissing me off that I'm being ghosted b Dynamic EFI. I guess they aren't interested in making money as a business that provides good product...WOW GO FIGURE! As far as China goes, NO WAY IN HELL I would do anything in or with China. People can say what they want about doing that type of thing to include me having the Renegade made in China. It isn't gonna happen. The tooling will rot before that happens.

 

Yeah i figured this out by going on a “84 corvette trouble finding ECM”, people actually use those TBI truck ECMs to get their 84s running with the only loss being an MPG light that won’t work on the 84s. But that wouldn’t be an issue on the 82 since it doesn’t have an MPG light haha.

They do this by creating a jumper harness or by just cutting off the OEM female harness off, and splicing the old harness connection that fits into the TBI truck ECM.

But i couldn’t do it, I couldn’t butcher her original wiring. Lucky for me my brother had an old 84 he tore down for parts and still had the ECM under a bunch of stuff, I really had to dig for it.

I’m interested in what their wiring is like, shouldn’t be hard to replicate with a diagram of both of the ECM pin-outs.


it wouldn’t be too hard to get some edge card chips printed at home or by a prototyping company (these connect to the OEM ECM harness on the 82-84) and then it’s just a matter of connecting the correct wires to it to whatever harness the donor ECM takes. It can’t be hard if you can read the wiring diagram.

I might actually try this project once I get my 82 to pass smog over here in Cali since I’ve been interested in those EBL FLASH II computers.

Anywho, once I get my baby on the road, I’ll try to see if there is a way of creating some kind of semi-DIY harness that can be used with these ELB chips or even 80s TBI ECMs.

HAM board would have been great since they save clutter, but they probably require soldering directly on the board which a lot of people are uncomfortable with.

An adaptor harness is probably a better solution for most, since there is still an abundance of old 7747 ECMs that can be flashed with EBL2.

or they could just use that adaptor to plug and play the 7747 TBI ECM.(Well, not exactly plug and play, not sure if the PROM has to be switched over, supposedly not for the 84s but not sure if it’s the same for the 82s)


Anyways, i might try making this a reality as soon as I get my car road ready. I’ve been stalling for far too long.

 

I did that conversation a few years ago when I first got my car.

I get about the part not wanting to hack up the wiring. I didn't have a problem with that being these cars aren't that valuable and the edge card connector isn't reliable and source of trouble too, especially when placed right next to a lead acid battery. You're better off hard wiring it.

 

any updates on cfi computers

 

Funny that you should ask. Bob at Dynamic EFI has passed away back in Sept and nobody knew it. That is why I could not get a hold of Bob. I have spoken with his wife who is now terminally ill, but those talks had stopped as you can imagine. Just the other day after me sending a certified letter to them, his daughter has contacted me and we have talked several times recently. Great conversation and I plan on, if it all works out OK to be purchasing the Dynamic EFI business. I have another call scheduled in a couple weeks since they have to get things together on their end. I also will be flying out their to survey the entire business. My site keeps everyone informed.

 

thank you for update and good luck buying it

 

Great news for the CFI Community.
Good Luck with your plans.

 

any news on this, did buy the website

 

Well... I have spoken with Bob's daughter numerous times since all of this bad news started and have sent various emails, screen shots of lines of code and more back and forth to see if anything looked familiar. I was contacted last Thursday by her and she sent me what appears to be the source code for the What's Up Display utility, at least the dates are within a couple days of each other on the code and the update from the website when it was still up, which is awesome. This is a huge plus right now. I fired up my Visual Studio and started coding some things in preparation for the future in case it happens to make some changes that I think are needed. Firmware source code is next.

There are a few more files and folders that are needed and "maybe" they are the ones I need? Now, we discussed coming out there to put eyes on everything to see what is totally involved with inventory, equip etc... I'm thinking and hopefully in June going out there? Everything is moving slowly, but it's on their end not mine, and I'm at their mercy on all this. There is NO firm update other than this which is only a few days old now. I wish I had better news, but at least we are moving forward. My BLOG as always has updated info on this subject and other things. I hope this helps. Have a great weekend.

 

thanks for update glad it is happing for you
