I'm patiently awaiting the J2534 support for the OBDXpro I just got! (And the GM D-PDU API for tech2win lol)Tazzi wrote:Gampy wrote:I could definitely supply a shipping address ...
Different J2534 devices are not needed at this time. Some have bigger buffers then others but that can be narrowed down at a later date.
The OBDXPro VT is VPW only, which is not used by this application, future models of OBDX will support canbus which will inturn be able to work with this application once J2534 is completedMudDuck514 wrote: I'm patiently awaiting the J2534 support for the OBDXpro I just got!

I just want to say thank you for giving the e37 attention. I've got an 07 G5 I would love to be able to tune.Yustas wrote:Hi Tazzi,Tazzi wrote:Anyways, all focus is on supporting a couple new ECUs (E40 and E92), along with the T42/T43 TCMs.
I'm interested in e37 support, to clone and tune ECMs for my DF Goblin kit car.
I have spare ECMs, tools (can, jtag) and skills to help you. Here is my progress I want to share.
I've developed gm/e37 support for caringcaribou (opensource python tool): https://github.com/YustasSwamp/caringca ... its/master
It can do correct unlocking and slow fetching of entire image (2MB).
I didn't dig towards kernel/bootloader development. At that point, I found this thread. It was nice to read your progress. It would be pleasure to my to try your kernel if you can share.
From what you've described, e37 seems very similar to e38.
Also I've started to develop e37 simulator. It is based on gdb/sim, as it already has support for given CPU ISA, I've added several peripherals to it. Fetched image can run several thousands instructions in this simulator up to the point where timer interrupt supports required. Adequate peripheral simulation is a biggest part. I can also share/open source it, so we can collaborate.
Thank you for info, will try it with my E38 ecus... hope this will helpIn-Tech wrote:Curiosity got the better of me so I put one of these E38's in the mill. Do I need to keep going or is this the flash? Looks to be a Spansion s29cd016j0mqfm01. So, where's the "reset, boot mode" pin? or is it accessible from the bottom removable cover?I got this somewhere in my travels too, not sure where. Just found this tonight for the Spansion. You guys probably have all this stuff, I'm just perusing for info
