Programming
2008 Chrysler 300 LX 2.7L (R EER) 4-spd (42RLE)
U1110
U1120

This is an odd situation. Bought a 2008 Chrysler 300 with a locked up 2.7 Engine. Swapped to a 3.5 along with wiring harness and 3.5 Computer. Initially ran off of 2.7 PCM and it ran fine other than running lean. Everything else was fine.

After installation of a 3.5 PCM for better engine management, it threw U1110 & U 1120. Loss of speed sensor. LX model cars were entry level and had optional ABS and 2.7 engine only. Mine does not have ABS. All other models had ABS as standard equipment and 2.7 & 3.5 engines as an option. So, you cant get a 3.5 Engine without ABS. Charger, 300, or Magnum are all the same setup.

I need to remove ABS from the PCM to remove the code and so that I have a speedometer and cruise again. Dodge won't do it because this setup was never an option. All they can do is flash to the VIN, or so they say. Once they do that, I lose the 3.5 programming. Computers for both engines and model types are identical. It's just how they get programmed. 

What tools/options do I have to basically custom tune the computer to the correct settings?

I would try to find a company that tunes vehicles. I am sure they can help you. Factory Chrysler programming does not let you change stuff like that unfortunately. If it was offered as an option then it would be possible. Even then I doubt you could convince a Chrysler dealership to do it, you would have to program it yourself or have a local shop do it.

In 09 they had 3.5's without ABS. Since the hardware is the same, you can simply erase and write the 08 pcm with the 09 programming without ABS. It should solve your problem. If you can't do it yourself or get it done locally, I can send you a PCM which will be ready to go. They are not expensive.

Can you give me a specific model setup that way? That'd be great. A VIN would even be better. Yes, the computers are the same 08-10. I just need a reference # to somehow get one programmed. I have a tuner that did my existing one. At the time I didn't know ABS was and issue. He hasn't messed with the ABS side so he's not sure how to edit it out. Buying a used one, the part numbers are all the…

Hi Jesse I have highlighted the one you need in this picture. I can do it for $100 USD including shipping via UPS Ground. Faster shipping is possible for not much more.

Thanks Jesse. Actually the mileage shown in the cluster is independent of that in the pcm. On your Canadian car, depending on the year, you can very likely swap in a cluster from a US car and not have to suffer with the km. If you don't have a way to reset the mileage to be correct, it will be off, but at least you would have miles.

I vaguely recall changing units in a Chrysler product of that age without cluster change ? Do I recall that correctly ? Or course, many vehicles allow unit change via scan tool if not by simple menu selection accessible by the owner.

Oh yes you can change the units of the odometer, but I assumed he was speaking of the analog speedo being a pain with the larger KM on the outside and small Mi on the inside of the gauge, since the pcm mileage, on the older cars, has no effect on anything.

Gotcha. I never found the 2 sets of markings on the analog gauge portion a problem which is why I was confused. I can't remember a customer complaining about it when they bring USDM cars into Canada. Depends on what you are used to. Getting used to km or miles on a vehicle WITHOUT dual markings is a pain for some. Cluster swap on a vehicle like that makes sense if it is possible.

Jesse, If you have used the Legacy J2534 application and are comfortable with it. you can change the calibration in the PCM. Use the Tech Tools application to download then use files for the J2534 app.

If you have j2534 passthru then do subscription with tech authority ..then go to legacy tech and setup reflash software. Very easy to reflash whatever calibration you choose you just have to get a little creative when downloading them from server you choose by vin or part number and options available like emmisions and with abs or without.. once you have appropriate flash then program in with…

Alexis, thank you for the information. A J2534 is not hard to come by. I think the problem may be the Chrysler Flash Tool. Where do you get that? Is it Chrysler only? I have not used Tech Authority, yet. If it is truly configurable independent of the VIN, then I'm okay. But if it relies in anyway to the VIN, then it's a no go. I am totally open to options and am not afraid to experiment with…

This issue has been resolved thanks to Mike Ismaily that replied to this thread. Couldn't have done it without him. Mike was able to custom tune a PCM without ABS. He found a calibration without ABS, programed it into another PCM, programed my VIN in and made a few other upgrades at a very reasonable price. Car runs and drives great. No check engine light and drivebility is like it left the…
