Re: E67 virtual eeprom repair

It should take 30 min to make a Jtag connection with the proper tools. Roughneck is spot on. If you have a diagram, and use something like PCbites for the connection, it takes 10-15min to take off a cover, 5minutes to place the probes… 2minutes to read then write a replacement.. then a few minutes ...

Re: OBDX Development - Developer Tools and Suggestions

No more techline disconnect being down would be fantastic, now if your software could spit out the warranty programming codes that would be even better!!! It was down yet again this morning for hours. We even started a bingo board with all the disconnect errors on the gm forum, guessing Chris wasn’...

Re: OBDX Development - Developer Tools and Suggestions

I have done a great deal of learning with SD cards recently, so much so I'd like to say Iv become a bit of a pro with understanding the nitty gritty of them. The easier connection to them is using SPI, this does not get you crazy fast speeds like you see with dedicated SDCard readers, but with the c...

Re: OBDX Development - Developer Tools and Suggestions

Yah. E67 and T43. For the T43 I'm hoping to read about 30 ram addresses between 0x300000 and 0x30ffff. Looking at torque converter state machine registers primarily. Haven't got to my e67 yet so nothing on that for now. Ooh that reminds me. I'm looking at moving away from my Tatrix to buy one of yo...

Its not something that would go into a public OBDX app since its not really something people need or use.

But could be put into just a very basic program to prob a modules memory, or loop through memory addreses?

Re: Ford programming Explained

The issue with OBDLinks is speed and packet size. The available ram inside of each OBDLink varies between the tool and firmwares. Its the 99% reason of problems in pcmhammer also for supporting them. Some will support packets of a few hundred bytes.. others will support just over 100bytes. So when a...

Re: How to properly define a byte in code with tvrfan's SAD?

Typically you would use a variable that is stored in ram, or flash to be able to turn a feature on and off. I do not recall what the ram addressing is for the EECV ecus, but for example: Ram address range is: 0x80000000-0x80010000 You could then save a variable in some unused ram area (you’d need to...
