1997 Chevy van reprogram engine ecu - starting from scratch
Hey guys, I have a 97 chevy van that I need to reprogram the engine ecu. I have a RAP from Drewtech but they only do 2001 and up I think they said. I have zero domestic programming experience and while I can call a guy to do it for me I would rather figure this one out so the next one I can do easily. I'm assuming I can use an autel passthrough device? Where I'm lost is where do I need to go to program this? Thanks!
acdelcotds.com/subscriptions J2534 pass through device if you have ever done it with a tech 2 it’s exactly the same. once you have paid for the sub one year access per vin number 45$ You’ll need to click the SPS icon and then go through the steps from there if you are using windows 10 or have any issues you will need to right click on your browser and open it in administrator mode.
I personally havent been able to program a GM of this vintage w/ anything but a Tech2 as a J2534 passthru. Cardaq-M wont let it fly (again, as had been my experience)
Anything but a tech2 will probably be too fast for that vintage computer. You will run the risk of having the module failing.
A tech 2 as in the small handheld scanner with a display?
IMO Tech 2 Remote would be your best choice, Requiring the use of a Tech 2.
So this is what I would need along with a subscription to SPS?
Ismael, be careful of where you get a TECH 2. Many companies are selling Chinese Knock Offs. They are very cheap (under $300.00 ) and I would not recommend using them for programming or diagnosing.
Ismael, do you still have the old PCM? If you do, just change the blue/white eprom from the old to the new one. then you may have to do the 3x10 for the security.
The removable eeproms went away when OBDII started in 1996, this one is definitely going to need SPS programming. I agree with using the Tech 2 in remote mode, many of the modern J-2534 boxes are too fast for this vintage ECU.
This is a 1999 Chevy Tahoe, that still has the eprom chip. Programmed today with no issues using SPS
Oscar, That's the knock module, removable eeproms were outlawed when OBDII was implemented in 1996.
Todd. Im not sure what are you talking about, I was referring to the one I showed on the picture, and base on the year that he was asking help (97). You are probably right, but in my time of doing programming, I have not run in to another kind or different than the one in the picture. I am always open to learn more about the other eeprom that you are talking about. I believe I found the one…
Have done a bunch using my snap on pass thru pro 2. Which is a Cardap plus 1. But in order for it to work, I must have 14v constantly on the car and the laptop has to be connected to power source or I would get failure around 10%, 30% or even 90%.
My recommendation is use a tech 2 or call someone with a tech2. The 97 is prone to failure using J2534,
Personally, I've never had an issue doing the PCMs on these older trucks using MDI (gen 1 cabled) and SPS. Use SPS and J2534 pass-through, you'll have to download the wrapper. It'll work without issue. Just did a 97 Express last week, and a 96 Astro the week prior. Both PCMs were salvage units. Some have a knock module under a cover that needs to be transferred (this is NOT an EEPROM, but you…
I just did a PCM on a 96 C1500 yesterday with CarDaqM and Dell with Windows 7 Pro. Breaking all the rules. I have my own Tech 2 and the shop has one but never had issues with J2534.
