Performance tuning that deletes the EGR w/o CEL

nursecosmo:

You might give Charlie a call and see what he has to say about turning off the CEL. He's a great guy and helpful on the phone. I have not spoken with him about the CRD. He turned off the CEL for EGR on my TDI, I know that doesn't automatically mean he can do it on the Jeep.

I gave Charlie a call and he was extremely helpful and provided a lot of info on the Bosch FIE. I may be working with him as well to get a tune dialed in for the CRD. He assured me that the EGR can absolutely be disabled without throwing a trouble code. I have also sent him an email explaining about our needs for a reflash to pre F37 programing but he doesn't do a lot of work with TCMs so may not be able to help there.

Excellent! Thank you for moving forward with this.

The first thing one does with the q-loader is download the vehicles current OEM tune and email it to Kerma. He might be able to use the q-loader to download the pre-F37 maps from a volunteer's vehicle that hasn't had the F37 done. He could compare to the downloaded parameters from yours and make the adjustments that way? That would at least let him see what the actual differences are. Just a thought...

Not to jump the gun...

Are ECMs interchangeable? I have the Inmotion tune now. Is this lost money if I move to a Kerma tune, or is there a way I can arrange an ECM swap with another 2006 owner, plus some cash?

I sure wish this tune stuff would have time to settle out before the SEGR group buy moves forward... I wonder if Kerma can play the same game with the FCV to reduce intake restriction, but keep shutdown smooth?

Edit: if this happens, anyone interested in an Inmotion tune?

I don't know the specifics of the CRD, but many ECUs now-a-days have the vehicle's VIN number programmed into it. In those situations you cannot just "swap" ecus. You have to re-write your VIN to the other ecu. Also, at least in the Mitsubish/Subaru ECU tuning world, once you tune an ECU with certain popular tuning software, it's "locked" to that tune. You would need the original tuner to "un-tune" it back to stock, then send the ECU off to another vendor. There were reports that this didn't always work either.

I had Jeff Roberts of Rocket Chip, program a level one tune on my wifes CRD ECU last summer. It was interesting to watch him remove the ECU and set it up on a bench and reprogram it. Jeff is well known at Freds for his TDI tuning capabilities and tours the US attending TDI GTG's on a regular basis. In addition to my wifes CRD he also tuned and or upgraded about a dozen TDI's that day.

He was a bit reluctant to program the CRD since he is well aware of the TC issues and didn't want to be responsible for hastening the demise of anyones transmission. We discussed different levels of tune and he basically can do 3 levels, however, unless you have the Suncoast TC, he probably wouldn't do a level 2 or 3 tune. He regularly turns off the CEL associated with deleting the EGR on TDI's, however he didn't want to attempt to turn off the EGR and associated CEL on the CRD. He indicated without doing further research on the CRD engine and knowing what is all effected by turning off the EGR, he wouldn't consider turning it off.

Anyway, the Rocket Chip tune really made the CRD haul stupid until the TC had to be replaced by the $tealership. It seems like the Stealership reflashed either the ECU or TCU. Guess I'll have to meet up with Jeff when he is out my way again and have him reflash the RC1 tune and maybe calibrate and install a boostvalve.

If anyone lives near Red Lions PA, you may want to look up Jeff Roberts of Rocket Chip and see if he would be interested in using your CRD as a test mule for further research. Pricing for tuning is about the same as Inmotion, maybe a little less if you can catch him at a TDI GTG.

I believe most major ECU tuners purchase their base tunes from the same suppliers in Europe and then depending on their level of skill, further custom tune the basic programs. You have to realize the market size for the CRD doesn't lend itself to extensive development and testing like the VW TDI market does.

IMHO Inmotion Tuning isn't in the same league as Jeff or Charlie when it comes to tuning and Charlie's tuning is going to be expensive. Jeff has been tuning TDI's longer than both, although, Charlie does has some interesting toys. If I had to do it all over again, I wouldn't hesitate to go with Rocket Chip programming again in both my CRD and TDI. Only problem is that Jeff is in such demand that you will likely have to wait for programming, but in my book, its time and $ well spent.

Should be interesting to see what Charlie comes up with to delete the EGR/CEL and the level of tunes he will offer. I'd be interested in hearing what turbo boost pressures he is running with each program and if he will recommend a boost valve ( cheap insurance) for his more aggressive tuning programs. Upgrading to larger Bosio fuel injectors if Charlie can figure out how we can do that and the cost/benefits of doing so would be great.

Just my $.02 for what its worth.

I've already talked to Charlie and when I get my CRD I will have him start testing on it. I plan on putting in a Suncoast TC as soon as I can. I am having a hard time finding a Pre F37 CRD. Everyone has theirs flashed. We have a GTG at Charlie's place on March 22nd and hopefully I have a CRD then and can start tuning.

I see 2005 Sports show up on Craigslist here in Portland regularly. To get an un-f37'd TCM, it might be easier to start scouting junkyards. There is a web site that lets you send out and email to junk yards around the country asking for bids on parts (don't have the address at work).

I have an Edge Tuner box that I am pretty happy with, but for a TCM flash I'd be one of the first in line.

I have a bead on one but the owner doesn't want to split the powertrain yet. I am working on him. I told him I would trade him and give some cash

. Has anyone tried to get a Tranny TCM from europe? I know someone in spain that would probably get me one.

Don't think the European option would work, I recall reading somewhere that only the US got the 545RE transmission in the CRD.

A recent poster from the UK gave his thoughts on his recent F37 flash :lol:

Here's the thread, 3 post down.

Maybe it was the older CRD's with the 2.5 VM engine... I recall reading here somewhere they had a 4 speed auto.

MrMopar64 · **Posted:** Mon Mar 03, 2008 10:04 pm

You need a TCM from a CRD with the 2.8L engine as they should all be 545RFE equipped. For sure '05 and newer all production automatic was the same 545RFE both for US and export.

Can't you purchase a TCM from the $tealership or do they only have the castrated versions available for sale? Personally, if my wife wasn't using it as a daily driver, I would opt for a 5 or 6 speed manual tranny with a performance clutch and $hitcan the slushbox. After the $tealership replaced the TC without upgrading the tranny pump, I told him I'd be back in 15,000 miles so he can put in another TC under the DC warranty.

What we really need is two TCMs. One (Pre F37) to have in the CRD at all times except when it goes to the dealer and then you put in the post F37 TCM. That way the Pre F37 TCM never sees the big bad computer download!!

Or, much better, a real 6 speed manual that matches up to the CRD.

What is the part number for the TCM and how much are they? It might be worth a try to see if they are flashed with a castrated version.

Nah, we just need a Chrysler equivalent of Vag-Com (VW's tuning software), allowing the ECM and TCM to be patched on the fly with a laptop computer.

Can I get a HELLL YEA on that one!

In the beginning before I got involved with the SEGR, I was going to buy another CPU from a junk yard and poke inside it. Found one for $125. I was then informed that it has to be programmed with the VIN number and all the other computer serial numbers.
Now true or false, I have heard that there is some validity to this as even the radio serial number has to be entered.
I can handle that but the part the bothers me is that I’m told that the only place that can enter all that information for me to make a “Clone” computer is the dealer.
That’s that part I don’t like.
Is there an alternative?

Trubo Tim,

Last time I checked Inmotion's web it states that they can clone ECU's.
