Engine/PCM swap, no VIN, how to program?
I'm thinking about getting programming software even though my computer was reflashed by a 3rd party already. But I may have a problem. I dont have the VIN from the car the engine/computer came from.
It looks like HPtuners wont be able to run without that.
Is that true, if so how about EFIlive?
I've helped customers with this issue countless times and its usually as simple as that. However you WILL want to have the vin actually flashed to the pcm and the proper vin change procedure followed so if someone ever needs to read the pcm again they don't run into the issue again, but writing to it won't be an issue in most cases from my experience.
I thought that would throw up red flags for liscensing issues.
I am not endorsing this but people have been known to go to the trader sites or ebay and use a known good VIN for a similar vehicle that you are using the OS from. The VIN will probably already be in your PCM anyways since whoever programmed it had to have one.
Back when I first did mine I just used a full tune from the HP Tuners repository and then made it my own. My PCM thinks I am a 1999 Trans Am.
I thought the VIN info was needed to liscense the software to a particular vehicle PCM. If I dont have the VIN up front, can the HPtuners get all the necessary info off the PCM?
