The interface should switch to x4 mode once it see mode a1 request. If you have avt cable there is a script that can do it.

lmao, that's a little too cryptic, especially for me.. care to explain? pm is fine if you want to keep everyone else guessing as well??

kur40, my logger won't switch over.. I don't know if I could look for the 4x request to the ecm and then disconnect and reconnect at 4x speed?? op, can you post up the last message you see with my program?? Or does anyone else know the 4x command request for the pcm?? my 1 bench vpw ecu is at work until monday..

the flashing tool will send

xx fe yy a1 example[6c fe f0 a1]
xx=priority can vary
yy=tool id can vary

and all modules will switch immediately over to x4 mode.

Thanks kur4o, I ended up hooking up my plow truck for a little experimenting.. Uses the same example you gave for 4 x switching.. as long as sps does the same for the op then the code below should work for him..
Same usage but select vpw and it should switch back and forth between 1x and 4x as requested.. Might have to change how I look at 4x and 1x request but hopefully this works out of the box, easier than I thought it would be.
<<< This version looks for speed change with Contains.. searches whole line of data, not good as it could catch search string inside kernel by accident?
<<< this version uses Startswith when looking for speed change request. Should work fine and not accidently see request in the middle of a kernel.. Have not tested this version yet.. please give me feedback..

Does it work with a VCX Nano? Those are $130ish and I believe they support J2534.

I can't make promises but it should.. The read buffer is tiny on the nano but I read it line by line..

I do have a really old MDI clone that identifies as a nano, I'll try and get some logging testing done with that..

Joukoy's UP Logger probably does and it works awesome.
