The MDI2 I have use of is one of two in the shop, and they're used with SPS daily to reprogram modules roughly 5 to 25 times a day without issue. I'll check on firmware/manager software updates tomorrow.

Attached are both my debug (pcmdebug.txt) and the one from Shortuning's test which looked like the same error that I had.

Hey everyone, To update y'all, I purchased an Obdlink SX to try and maybe rule out the interface. It worked! the used pcm is not bad :punk: but damn the sx is slooooowwwwwww lol. quick little breakdown of what did/didn't work: (0411 w/12208322 os) Pcm Hammer v4/5 w/mdi2 failed to read full contents ...

I thought from what I've heard that the p59s arent supported yet, or can only be read. Ive only tried it once or twice but it failed to unlock. Itll be monday before I can try again for debug logs. I really need to get my own interface :) I was happy to know p59 support in the works because prior to...

Thanks everyone for the help. I believe the MDI2's are oem but I'll have to look deep at any differences come monday. I have a terrible suspicion the pcm is faulty. I didnt personally pull it from a running unmolested vehicle, I grabbed it for 49.95 on ebay. I have 2 P59's from retired work vans fro...

Ill tear down my harness today, and check all solder joints, etc. I had checked continuity on all the wires the day I put it together, but Ill do anything at this point to help rule things out. :) My only interface option is two MDI2's at work, and they work nice and quick for oem stuff. At this poi...

Is it possible that the pcm has been tampered with, yet still accept an oem calibration? Id feel really bad if that's the problem. I dont like wasting other's time

Im using an MDI2 (perk of the job) The starting process of reading happens in literally 2 seconds up to the "requesting data" thats when theres a pause

Wow! You werent kidding about the txt vs pages of code lol so much cleaner!

Okay, so these are the results and debug after wiring in a switch on the ignition power and cycling ignition like I should Also, this is after a successful SPS calibration update. I appreciate everyones insight on this!
