If that works, I'll have a working test platform where I can reprogram the FICM flash! Now it's just a matter of desoldering the memory module from the board, tacking down an adapter to the emulator in it's place, reading the ROM image from the memory module with the chip reader, then loading that image on the emulator to test. As an update, I've gotten my hands on a chip reader and a 16bit ROM emulator. :dunno:Ī bit of an update on this - well not much progress, but a request - see below. I think they more recently added a 3rd CAN network on OBD2 using pins 3 & 11? Not sure what that's used for, but all these changes would require different capabilities in the module hardware and might explain some of the part number changes. The idea behind this was to isolate hackers who might be able to get into the infotainment from being able to control the parts that physically control the vehicle. They used pins 1 and 9 to drive a dedicated infotainment CAN network (head unit, satelite radio, gps, gsm networking, etc) in addition to the standard PCM/emissions/diagnostics CAN network on pins 6 and 14. As long as the they are using the same processor and have a similar set of IO ports, I doubt it's a big deal.Īs an aside, around 2006 I know Ford switched to using two CAN bus's, both exposed over the OBD2 port. Their firmware still might be compatible with each other, though. If I get anywhere, i'll can share the results.Ībout the different PCM modules - it's not too surprising that there are different part numbers. As easy as these trucks are to steal, a little goes a long way!Īny chance you could share some of those hex files? Knowing the processor type, I can try to load them up in IDA Pro and get started on the fun part - reversing the software PM me if so.
For example, imaging if the PCM firmware could be reflashed to add an 'unlock code' that's required before allowing enabling ignition - say a 4-button combo entered via the cruise control.
That's my biggest motivation, having had my truck stolen before. that's how those products exist I'm not interested in making a product or going into business tuning trucks - I'm just curious and by the looks of tings, I'm not the only one interested in learning more about this In the Mitsubishi community that I used to do this stuff with, the opensource community was the first to add options like on-the-fly map switching (using just the crusie-control buttons!), launch control, no-lift-to-shift auto rev matching (for manuals), valet mode, etc.īut what I'd REALLY like to see done on the 6.0 is some simple anti-theft mechanism! Spending $500 on a stupid alarm that goes off every time a squirrel jumps on roof, but can be disabled by any half-bit thief is less than ideal. Exactly! All the aftermarket options you have to pay for have done this.
