I'm from Bulgaria and i recently purchased a Jeep Wrangler with a 6.1 Hemi engine from US. When i drove the car to my dealer he put by mistake the VIN of the car instead the engine VIN. After that the car doesnt want to start and when i put it to ignition it shows EGR error. What should i do? Has someone had a problem like this before?
The issue is that i dont know which is the company. Actually, we found a way to start the car by making a button and with which we skip relay. The car is running now but it keeps showing the errors and that its running on less cylinders but its actually running on all. Isn't there a way to swap the computer or something so that the car can be started as it should be with the key and not to see these errors?
what @Nucleophile is correctly informin you is that, without whatever proprietary software programming that the engine swap was performed under ( he listed 3 of the 4 most well-known JK/JKU swap "kit" manufacturing /conversion & installation shops for HEMIs : Dakota Customs, JSS, BOR & I'll add RPM Extreme) , even if you are able to bypass certain limitations that were incurred by the INCREDIBLY STUPID & NEGLIGENT dealership that flashed the firmware on your engine-swapped Jeep's ECU, nothing will permit you to correct that on your own.
The conversion prosess involves - among other things - a tuner and a custom configuration for permitting the very sensitive Jeep JK's "drive-by-wire" system to be hacked into functioning with a completely different engine and transmission . The best ( i.e.- costliest) houses ( shops) that do these type conversions have the software which yields the least amount of system alerts and warnings - permitting OEM functionality with a completely different power plant and transmission...that is the reason there are only a few . They took the time and investment necessary to figure out a way to bypass the factory requirements and make the factory functions work without lighting the dash-up like a Christmas tree with warnings...
The only way to truly circumvent this on your own would be to yank-out ALL of the stock wiring harness ( there are miles of it . Check out one of our fellow members named @KOWBOY build ( the Turd) and youll see a removal of the JK factoy wiring ) and find some HEMI aftermarket control ECU and wiring harness then program it yourself . Other more savvy guys can confirm or deny this but that route essentially configured the Jeep as a totally different vehicle and will cost some serious dollars to have done properly.
If I were in your shoes, I would call each of the aforementioned conversion shops and provide them the VIM number , asking if they can assist you with a bad situation , seeking help , maybe they can reference the Jeeps which they have performed engine swaps upon until you find the right one . Then, hopefully, you can purchase a new programmed ECU from them to swap for the one your dealership destroyed. If you are lawered-up , you could try to get the dealership to pay for this since it was partially their fault.
Whomever you purchased it from should have told you to never allow dealer to flash the computer OR - many converted Jeep JKs have them - there is lots of times a notifying emblem or cap that is covering the data port under dash ( by driver's left knee ) that tells a dealership to NOT flash the computer due to the conversion tune.
I hope that helps. (I have no conversion but have read a boatload on our forum and elsewhere because I plan to have one in the future, fwiw. )
Make sure to refer to your Jeep JK as a Jeep, not a car ; the Jeeps get all sensitive when you do that and if it hears you, it may make it more upset than it presently is.
This is a message from the previous owner...
I have no idea. That drivetrain was built by Burnsville Offroad. When I bought the Jeep and changed out the various parts to get a vin and title I never messed with Frame. In fact never looked at frame for a vin. I just recently found out there is a number on the frame. They may have used a different frame for built. Not sure. In the states it doesn’t matter. The state police inspect every salvage vehicle and I’ve never seen one look for a number on frame. That frame had stuff welded to it for the long arm lift and also had the front frame custom modified to accommodate large tires with very little lift. The new frames you buy have no vin on them. Sometimes guys get a donor frame and grind off number and use it as a new one.
