View Full Version : Haibeck chip install...need help.....

04-18-2014, 03:30 PM
Purchased the Haibeck chip for the 94, received it yesterday and went to install today.....some confusion.....BTW, trying to contact Marc, but his regular line is giving me the fax signal.
In his instructions, it shows an adapter module, where the top half of his chip plugs into. I do not have that adapter module. I can install his chip, but all of those pins are exposed, there is nothing to plug them into.
Now my ECM label is worn, so I can't determine any part numbers.
But here is the info on my PROM that is in the ECM:
95 BKKR LT5 Proposed 95 ESC
ESC 0647
93-95 MY
PROD
T. Holand
3.30.94
So can this chip be installed with those pins exposed???
Do I have the wrong ECM in the car, because it doesn't have the adapter module for those pins to plug into???
thanks for any info............Tom

Tom,
Where in pa are you? I don't have a 95 but on my 90 it's fairly simple, remove 4 or 6 screws holding down the cover with gasket, take that off, there's 2 small clips holding the chip in, pull those back, take the old chip out pop the new one in, replace cover. I'm sure that someone with a 95 will be along to help you out.
Now that I think about it I did the same process with a 94 test ecm I used.

Hi Tom!
I have a MY1995.
If you have Marc Haibeck's performance PROM, Kevin is
correct. You straight swap your OEM PROM for your new
PROM.
If its a Haibeck smog PROM, xfirez51 is correct. You have
to piggy back your Haibeck PROM with your original PROM.
Then remove the blue plastic cover on your original PROM
(2 plastic tabs on each side) so the both will fit and maneuver
them inside the window/ECM casing and push it carefully
into the original motherboard slot. The retaining tabs should
flip back into place. Should have come with instructions that
include pictures. Any other questions PM/email me.

There's instructions on PDF posted on Marc's page too at the end of the paper that describes everything the chip alters.

Figure it out with the help of everyone.....thx to all....:cheers:

Yes, finally did it that way, I won't even tell you how I got the original chip into the ECM with the blue cover on and hooked up and then taken apart and out of the ECM, then blue cover removed and hooked up the correct way. No I won't tell you at all how I accomplished that maneuver...:eek:

Ted, I have a 94, but on my PROM it has 95 references......and thanks for the offer to contact you for additional help........
I also did not know that there was a Performance PROM, along with the Smog PROM, unless the Performance PROM is the custom build unit???

Yes, I did see and have the instructions that you mention, just was brain dead the other day and was not used to plugging a chip into the existing PROM as this one required......

Latest update......chip installation successful........took it out tonight, and runs extremely good. Enjoying the fans coming on at lower temps, did not go above 213 degrees at a standstill, so very happy about that.........just have to drive it more and more and more.......feels very strong......glad I made the change....

The Performance PROM I am referring to is the one Marc provides for headers, porting, anti-backfire, etc.
It is a custom PROM where you can also set the fans to come on earlier, set the "key on" to default and/or other items.

That's what I thought. ...I think that this may be one of best mod's I could do for the engine at a reasonable cost.....

Glad you got it popped in ok. Marc does a great job and a lot of guys here are running his program, including myself. He's also a really good guy. I went from the very original tune in my 91 to his, so it got lots of updates, but the big selling point to me was that it's easier to start when hot (nice, since I live in the desert), lower fan temps, no more skip shift, and a generally smoother running motor. I haven't been to the dyno to see about power differences yet, though.
And yes, daisy chaining the chips is a little odd compared to what most of us are used to, so I can understand the confusion.
Enjoy the car!

Thanks Steve, all I need to do sometime in the future, is follow your cleaning procedures that you are doing on the 93....which looks great....and btw, if you ever decide to let that go in years to come, just keep me in mind, I might even consider selling my 74 BB for the Yellow 93....you never know...:)
Talk to you soon......................Tom

A little confused here.Why are you using the interface module in addition to the stock prom?The reason Im asking is I recently had to have -some help- getting the car to pass smog and and I bought the interface that plugged into the stock prom for the sole purpose for passing smog.After it passed I took the interface out and now the car has one prom.

You use a daughter board if you don't want to erase the original cal on the stock prom. The daughter board bypasses the original prom but utilizes the knock sensor on it. You can download the original cal then erase stock prom, burning new cal onto it.

Tom,
That is an interesting chip ID
95 BKKR LT5 Proposed 95 ESC
ESC 0647
93-95 MY
PROD
T. Holand
3.30.94
Tim Holland worked on the LT5 program for Lotus, the car must have been in the "captured test fleet" at some point for it to have this chip in it.

Graham,
Your giving me goose bumps.....:o this is all new to me as I did not follow in depth the development of the ZR-1 at the time.....so if you don't mind, can you tell me more about Tim Holland and the "captured test fleet", it seems like it will be very interesting to say the least. I should have taken some pics of the PROM while it was out.
The following is what is on top of the Blue Cover of the PROM
will take a pic soon.....
on a small sticky.......95
............................ESC
on the White Label directly under the small sticky.
...........................BKKR
.........................."0647"
..........................93-95MY
............................Prod
..........................T. Holland
..........................03.30.94
Now on the sides of the actual PROM in white marker ir reads...
on on side............LT5 Proposed 95 ESC
on the other side...T.Holland
wow, does this mean it may have been a test vehicle for future development at the time???
could it also mean that this was the proposed PROM for the 95 LT5???
Thanks for any additional info................................Tom

Here is a pic of the Blue PROM cover that was on my 94.
Also update on the new chip, working great, really like how the fans come on @ 205 and off @ 200 degrees......
