So I finally got myself a spare ecu for my LNF. I was just looking at how I install it to get the VIN # on the ecu to my car's VIN.

I tried searching but had no luck (one reason because Idk what the hell to type in the search).

I heard some rumors a few months back that if you don't do it right the car will think it's being stolen? Not sure the truth behind that but needless to say I don't want that to happen.

Anyways just hoping to get directions.

 

Really no replies?

All I'm looking to do is to install an ECU with a different VIN # than my car without any problems.

 

I switched mine with no problem. Worked perfect. I think the device that stores your vin is seperate from the ecm

 

So you just plugged it in and everything was fine? How long did it take for it to learn the new ecu?

 

well for whats its worth, i have a Skye ECM in my car from a 2009, and we had to "borrow" a vin from a 2009 Skye for it to accept the HPT file.

 

Make sure you disconnect the battery before you swap out the computers

 

So disconnect the battery swap ECU's and I'll be good to go? Or is there more to it than that. Do I need to let it sit before I connect the battery again or start the car to let it learn?

 

I seem to remember that you have to turn the key to the run position (not trying to start it though) for like 30mins and basically just leave it until the security light on the dash goes out. When the light is out, the ECU has been paired with. That's what I seem to remember hearing from a while back. Somebody may need to add more or correct me on that though, since it's been a while since I read up on that topic.

If you're able to flash the VIN to the ECU first, then you just pop in the ECU after flashing it, turn the key to the run position, back to the off position, and then you can start it like normal after that. For instance, if I reset my ECU, I can just pop it back in, turn to run, turn to off, and then it'll start like normal since it's paired with the ECU already.

Sorry I'm not 100% sure. It's been a while and I've never had to swap ECUs, much less new ones.

 

Where's BYT and Terminator2 when you need them eh? haha... You might try the Hp Tuners' forums, someone there might be able help out.

 

I remember reading that someware as well

 

You were close, Stamina. Here's the key relearn procedure, compliments of the ZZP web site. I do believe the ECM needs to be paired to the VIN; when you order one on ZZP's web site you have to include your VIN with your order...

For the seed key relearn, this is the procedure:

You can open and close the door- It doesn't matter. You will need to get in and out since you need to push in the clutch.

1. Depress the clutch and try to start the car. If it does not turn over, let off, but leave the key in the run position. The security light should be lit up on the dash.
2. Wait 10 minutes(you can open the door and get out). The security light on the dash will turn off after 10 minutes.
3. Turn the key off for 5 seconds, then depress the clutch and try to start the car. If it does not turn over, let off, but leave the key in the run position. The security light should be lit up on the dash.
4. Wait 10 minutes(you can open the door and get out). The security light on the dash will turn off after 10 minutes.
5. Turn the key off for 5 seconds, then depress the clutch and try to start the car. If it does not turn over, let off, but leave the key in the run position. The security light should be lit up on the dash.
6. Wait 10 minutes(you can open the door and get out). The security light on the dash will turn off after 10 minutes.
7. Turn the key off for 5 seconds, then depress the clutch and try to start the car. The car should start on this attempt.
