Well, I got tired of trying to figure out a way to reprogram the EGS51 at an affordable price($1300 Euro to $2450 dollars is not worth it in my book) and paying that each time I want to change some parameters, shift points, firmness etc and decided to give this programmable TCM a try as it gives you complete control and also offers some upgrades.

I'm going to use this thread to document the process of attempting to make this work with our cars.

I bought this kit new from a fellow who purchased it(never used it) from the dealer supporting the 722.6 trans:

I'm in contact with Russel and he seems to know this controller in and out so hopefully we can get this sorted out and give us Jag guys some more tuning options for our cars.

 

Subscribed; popcorn in hand.

 

I smell a group buy......


Pioneer it Adam!

 

Subscribed.

 

Make it so, number one.

 

subbed,

 

I am interested please keep us posted.

 

Hope it will workout!

Is it also possible for this device to send out custum messages on the CAN bus?

 

J1939 CAN

see this document under the "developers" tab

http://www.powertraincontrolsolution...ges%20v2_1.pdf

There are also a number of other developer documents.

 

The Jaguar ecu is expecting a signal every 40ms iirc from the TCM, so when this unit can send that message in these intervals there is a good chance you can make this work. I'll take it the original gear selector can still be used as that one is also sending gear selector state over the CAN.

 

Well, according to Russel the original shifter(dual linear switch) can be wired to the controller by utilizing the digital inputs. It can be also programmed to utilize a can bus (touch-shift) shifter from an mb or a chrysler to accept the commands through the can bus. According to the manual it can also accept commands through the can bus from other sources through different modes. Ie steering wheel button inputs.

He is currently working on the TCM to ECU communications for MB and Chrysler, which I know utilize the egs52/53.

With the EGS51 I know it uses a different token as if you plug in an egs52 the ECU throws a code.

Russel mentioned that the PCS TCM can be programmed to talk with the ECU but we would need to know what the ECU is looking for. So if anyone as this data it would be that much easier to make this plug and play.

 

Here are 2 older traces I made, 1 with a working TCM and 1 without a working one (a reprogrammed EGS51 that didn;t communicate on the CAN bus). Both from Ignition on, so you can see the differences.

 

How about replacing EGS51 by EGS52 like this guy has done for his MB. transmission blue top solenoid modification for faster firmer shifts - MBWorld.org Forums Post #15

 

Our ECU will not talk with egs52. Mb guys have it easier as they can use Star to change the ECU settings and load up a newer tune to make it work with that setup. I tried to upgrade and now I got an egs52, shifter and a newer spare tranny with the updated valve body sitting on a floor in my garage. Good thing got them cheap. Plus EGS52 is not "that" easy to code. Just easier than egs51.

 

What are you using to sniff the can?

 

A can opener!

 

Standard IDS tool by reading it at 500 Kbaud.

 

The VCM?

Are you using any special software with it?

 

No, all standard.

 

Any news on this one?
