Hi does anyone have a factory oem Eprom available for sale? I'm having trouble locating one. They are discontinued through the dealer. Its for my 92 Ty but pretty sure it would work out of a 93 or a Sy.

Mine has been replaced with an aftermarket chip.. I believe its a KennyBell chip ive done some searching and seems its not a good chip to go with.. at the moment I was wanting to replace it with a stock prom to see if it solves my problem.. Its running insanely rich.

I thought the factory eprom was attached to the kenbell chip/adapter just like all other chips and adapters! like the ultimate and moates

I might be completely wrong than on what I'm trying to replace.. I'm not very familiar with ECUs but I'm trying to get my ecu back to stock. I was told in order to do so I would need to replace my Eprom since I have a KB chip. Does that mean I'm in need of a factor chip? thank you for your assistance!

Re: Looking for Oem Eprom

As far as kennbell chips. I was under the impression that it was just another chip adapter that the factory eprom connects to. If that is so. Remove the kennbell chip with the factory eprom attached to it. remove the factory eprom from the kennbell. Install the factory eprom in your ecu. if you are going to use a factory eprom. make sure you also install a factory map sensor. Most aftermarket chips require a 3bar map. I could be full of shit on this one. maybe someone who is more familiar with the kennbell setup will chime in.

KB did not use an adapter, the were a seperate memcal. ATR chips were single memcal solutions as well. One of the problems with KB was that Memcal that KB used wasn't even a SyTy memcal, so even if you bypass the EPROM portion of the chip with adapter the esc spark retard portion still doesn't work.

Quit spreading misinformation.

Kenne bell chips did use syty memcals just like atr... all syty memcals have the 114xxxx on the esc circuitry




If you don't know for fact don't tell people something you can't prove. Look at the picture above...

Reread what I wrote. I basically wrote what you wrote.

No... you said that the esc circuitry was not the same in the Kenne bell chips. You are 100% wrong.



Here are all 3 a stock an atr and the Kenne bell all have the same esc circuitry...

The 1st 3 bar was the ultimate chip and most of the chips after that that were based off of it.

The Kenne bell and atr chips were all 2 bar.

Brian Geeen told me that 15 years ago. He said you can't use them to piggy back to ultimate for that reason because the esc didn't work properly. I trust his word since he did the tuning portion of the ultimate.

Re: Looking for Oem Eprom

I'm pretty confused now, I just got off the phone with the GM dealership and it was the same guy i spoke with yesterday in person. I explained to him that the Eprom is not what I was actually wanting to replace and that I just need a factory chip and I proceeded to tell him that I was told the Eprom is what the chip goes into. He cut me off and said no the Eprom is the chip. We went back and fourth for min but he held his ground on the fact that the Eprom is the chip.

So ill try my question once more here just so I can further pursue finding the part I need lol. At the moment I have a KenneBell chip and want to replace it back to factory for the time being. Would I need to replace the chip or the Eprom? I know some of you already have tried answering it for me, I just wanted to make sure everyone understood what I'm after.

Thanks

Ok. I hope this makes sense. there are 2 sides to a memcal. one side is your eprom (black). That is what is modified in tunerpro or datamaster to tune your truck (fuel map, timing, boost,ect). by using a memcal adapter. The other side of the memcal (white circut looking thing). we dont mess with that. When people say thay have a chip. they are talking about the eprom. When other people say I need a chip. they are talking about a memcal. The word chip is highly misused and confuses the shit out of people. Here is a video that might help with what I am tring to say.

Re: Looking for Oem Eprom


You have pictured a 40# KB street chip. I have looked at the bins of the stock injector KB street chip which pull 0 degrees and the 40# strip chip (or what they called it) which pulls 4 degrees.

Have you pulled the bin if that chip and does pull any timing when knock is detected?
