New ELM arrived today, but still having the same issues..

Though I've got it working though by flipping the high and mid wires around and running full speed.

Doing a dump on my FGX dash currently, when its done i'll go pull the GT-F dash out of the car

1D7 does not appear there - I reckon it's a bogus signal when the chip is first configured, especially because it's only 7 bytes, and these things are configured to always generate 8 byte messages. Sorry mate.
Interesting, CAN id 408 are.you sure that's.correct, I get it as 409 in what I've done. Also interesting that ID 313 (cabin temp sensor byte 0) from.the fdim - this can id also contains all the "switches" you can change in the various radio, rds, program types filter options in the FDIM. All the radio, cd, MP3 stuff is in there too, as that can be displayed on the MFD.

How tall a step it is from here to adding stuff here and there, eg display a small engine diagnostics menu like many newer cars have, and successfully flashing that modified firmware back into it successfully?
Steering Wheel Controls could be implemented to control the menu as well.....the list goes on.

Yeah, I know, it's slow, sorry...

For the cool things my software attempts, it doesn't need a great deal of speed... And for the limited use stuff (like getting 'that' part of the firmware) once it's done, we never have to do it again. I know though, it's a bit annoying.

Honestly its fine, though if its going to take awhile I may as well just start again with the GT-F dash.

This first run, was just going to be a test

Ha ha, Jakka... I get it as 406! That's what you get when you're using Window Calculator with a mouse! And the Mk1 firmware is using all of the 256KB of flash it has available, so there's no "adding" to it - only small patches are realistic.

The biggest problem with the Mk1 (other than the ELM not being up to the task, due to the high speed of the data extraction's routine) is that it's not designed to be "updated" while it's in the car. You need to get into the programming mode by powering up the unit (from OFF, totally OFF) while sending in a "denial of service" type attack on it! Your car will not like it, unlike the EEPROM (and RAM) stuff I got working on it.

I am (slowly) piecing together a python script to do it, via socketcan so the ELM won't be a problem. Currently it is not very dynamic, so it will generate the key from an error message if that's what it receives instead of a seed. But have successfully gotten seed and generated key within the script..

After I get a handle on reading the EEPROM with socketcan I will try for the deeper stuff.

From what I understand (latest) EXE is the same in the GTF as it is in the normal FG2.

It's the SIGCFG that's different (5000-10000).

I'll just dump the signal config then for you now, that one doesn't take long.
Just so you know, last time I had it connected to forscan
AR79-14C025-AB was the 2nd boot loader
AR79-14C026-AH was the strategy
BR29-14C318-AA was the signal config

Thank you Superb! That's awesome!

The firmware converted over perfectly - and I can see the magic number (at the end) is correct - so I've uploaded it to github. I'll be checking out the differences soon!

Default Re: FORD technical service bulletin : ICC touch screen display

The question is... Does it work? Well, after fighting Forscan for a few hours (seems it doesn't necessarily like programming firmwares in devices that didn't come out of your car - I had to revert some saved config files to get firmware programming back!)... Yes, it does work:



I stuck a slightly better [glare wise] picture in there. And yeah, that Cluster is made up from spare parts from a Terry SZ, a Mk1 G6E and a Mk1 5.0 FPV... All the really good stuff ended up in my car, but I had enough nice stuff left over to make a spare MKII Cluster

Yeah, I thought of that about 2 minutes after I had posted... And I checked. And I couldn't find any in the extracted firmware with either the real number, or the number multiplied by 4. And I'm not even sure your description of that is true, the cluster is a gateway, so it can transmit (some of) those in that function.

What may also make your head hurt (it does mine) is the FGII signal configuration doesn't contain the CAN IDs that control the dials - unless it's the GTF specific file, which transfers data through the CAN bridge. They are well hidden.
