Re: Open source GM OBD2 flash tool using a ELM327 device

I hope so, that guy is an ACE in my book I've read a lot of stuff he's posted. 4x VPW is very good to know :D . I hope your right and I probably just went on a search tangent, also a little frustration is setting in; albeit no response from A1 has rattled my cage. I messed with the IFR and still get...

Re: ELM327 Which one?

I got a obdallinone from http://www.webpg.net/ but id look into scantool http://www.scantool.net/scan-tools/pc-based/ mainly because they offer updates for their interface. That includes extra features that a normal ELM doesn't have through "AT" commands.

Re: Open source GM OBD2 flash tool using a ELM327 device

You dont need 4x to flash. It just takes 4x longer without it! 1. if we could devise a way that "takes 4x longer" to reprogram the PCM I'd be ok with that. 2. According to http://www.akmcables.com/obdii.htm <--(typo here caused the edit sorry) the people who made the cable for LS1edit a &...

Re: Open source GM OBD2 flash tool using a ELM327 device

vn5000 thanks for the follow up on the $AE structure (6C 10 F0). Have been doing a lot of reading/searching and found some interesting things. First according to ELM http://elmelectronics.com/obdtips.html they don't support J2411 single wire CAN or J2534 pass through. Now short of saying i'm getting...

Re: Open source GM OBD2 flash tool using a ELM327 device

Its a PSOP-44 socket, and you'll need good SMD soldering skills. You should be able to find what you need with google. If your not confident of your ability, I recommend finding an electronics store that can do SMD rework and hiring them to do it for you. Haven't picked up the PSOP-44 yet the price...

Re: Open source GM OBD2 flash tool using a ELM327 device

Bricking ($60 + for a new PCM) is a very REAL possibility without the right programming antus, I'd like to get your setup. I'll Pickup the stuff to socket my pcm in-case-of-brick if you don't mind sharing your setup.
