Chip Claims to "turn off EGR"

You will need the module from an '05-up liberty. The hardware changed @ the 05MY from the EDC15 to the EDC16C2.x.

The chip inside the Bosch controller is encrypted very heavily so I'm not sure how they plan to actually copy your software code. I suppose they could just copy the hex but then you'd need some form of compiler for the chip.

When you get the new controller, you will most likely need to have your VIN flashed into it as well as the codes for the injectors for the quantity adjustment. These values are stored in a portion of the controller that gets overwritten when a dealer does a flash, for example, so I'm not sure if the company doing the chip will recognize which values inside the chip contain these values.

So are you saying that a module from ANY 05 and up liberty will work? Not just one from a diesel. If so are the same modules used in any other vehicles?

No, it will have to come from a CRD KJ - they're the only ones using the Bosch controller. All gas KJs use the NGC-IV unit.

Really appreciate the info....they never make it easy for us do they. Why in the hell don't they just use the same ECU in all Jeep products and just change the programming. I guess I'm just spoiled using A/B SLC's.....same hardware differant program or that is too simplistic..... :evil:

Now I have to find a CRD ECU and that will be more difficult.......maybe overseas??? I'll bet all the years use the same ECU???

Yeah...it becomes an absolute cluster in the vehicle with all the modules. For gas vehicles, the trans and engine controller are in the same ECU which is convenient. However, with the CRD, the entire engine fuel and electrical system along with the software in the ECU are from Bosch, so you then end up with having a gazillion ECUs all over the car.

Do the overseas models use the Bosch????? There a lot of WK's and Liberty's over there which would enhance our abiltiy to find a compatable ECU.

Overseas KJs for sure use the same Bosch controller that the US KJs have. It's a Bosch EDC16C2.x . There were different HW levels at different points...I know for sure that the 05 and 06MY vehicles would be compatible.

From what I can find so far, it appears as though the WK uses a different variation of the EDC16 (EDC16-U31). I am not sure if they're compatible without being able to examine the powerstages internal to the ECU and the processors to make sure that everything is compatible.

For the time being, I'd just stick to finding KJs that no longer have a use for their controller...

Another question concerning cloning our existing CRD Bosch EDC-16's. If you have the security package, does the SKIM programming complicate the cloning efforts?

MrMopar64 · **Posted:** Tue Nov 14, 2006 11:16 pm

The SKIM should communicate with the EDC16 over the vehicle's communication bus to release the engine to run. However, if the VIN in the EDC doesn't match the VIN in the SKIM module, then it'll shut the vehicle down after +/- 2 seconds at which point all the codes will need to be cleared with a scan tool before it will run again - thus why it's important that the VIN be programmed into the vehicle before starting. If memory serves me correctly, only a Chrysler Scan Tool (StarScan, etc.) will be able to program the VIN.

Bumped this hoping to hear from crdmike about results.

Sent that previous post while driving back from Thanksgiving vacation.

I've been 1000 miles since getting the tune. Sent it off to GH on Monday and needed it back no later than Thursday which is when it returned. I did worry a bit just cause it's risky being without the "wifes" car!

Reinstalled the ECU and heres the results:

Went with the Stage 2, mileage is about the same 20-24 but I've been puttin my foot into it.

Raised rev limiter: I can hear it spool up with a little fuel in park.

Power is touchy, studder/shudder is prominent with increased torque, just have to feather the fuel a bit until I replace this POS torque converter with a real one.

Very happy with the results.

If you have 2 ECU's seems like the perfect answer, Switching back and forth is not big deal, but doesn't the ECU contain data on the last X cycles?

So switching back to a stock ECU before taking to the dealer might be as big a tip off as leaving a tuner box installed. If there is date info or time since last cycle info. I'm concerned that bringing in my KJ to the dealer because it threw a code, and then have them notice that the KJ's ECU says that it has been sitting on blocks for the last 6 months? :oops:

But... If the tuning is undetectable, no reason to have a second ECU except to have a spare one when I send mine in for a new tweak to the programming.

Thoughts?

No one but CRD owners know what Common Rail is and I got tired of people reminding me I wasn't at the gasoline pump

<<-- No, THAT's a big @$#% diesel badge.

(Okay, its a tire cover, not a badge) Looking out the window to the parking lot, I can read it from my desk.

Nobody had tried to help me find the gas pumps before I got the tire cover. I have had a couple people filling up other diesel vehicles (and a few pump attendants) ask me how I liked the CRD.

"then have them notice that the KJ's ECU says that it has been sitting on blocks for the last 6 months?"

I'd like to see that P code :-)

Wouldn't mind it just to see the tech's reaction. But you raise an interesting question. Does the odometer reading stay in the ECU or elsewhere? Might be a bit of a problem if you come in with 20K fewer miles than the last visit, on the same VIN...

As for messing with the dealer - one could fabricate a bracket for the 2nd ECU, and put both ECU's in next to each other - but the 2nd one would only have a dummy connector on it. Install a big red handled copper A-B thow switch and label the ECU's "Primary and Backup".

If only one could videotape this setup at the dealership when getting the TSB de jour. You could always tell them you throw the ECU switch to Backup when the jumping/bucking/shuddering starts and that stops it. Then tell them an out of town dealer installed the 2nd ECU as part of the latest TSB flash update :-)
