you need to edit the cfg file to match the com port of your cable. if it doesnt work the cable/program wont work togethor. Yeah I have edited it to suit the comport with a Envyous Customs cable and also purchased one off here and edited it to suit that. It still just has the same error, im doing so...

Bit of a dig, but I have a similar issue currently. P01 has a HPT OS 1273001, and PCMhammer thinks it has a 0kb prom, so won't read or write to it. HPT works with it fine

How intensive it the install? I do basic video game console mods, so I'm not scared of too much, but is it a diy job?

Bit of a dig, but is there a way to swap segments, without sps? Is dps and modded ID files the only way?

I haven't had a chance to test yet, but I'm fairly certain the switch to enable Engine Oil temp sensor on x2-65 on OS 6281 is at 1FEC62.

HP tuners actually lists the driven wheels switch in system tab.
RWD, FWD, 4WD
It then has the option for early or late CAN. Not sure if it works yet.

It also lists pulse changes for VSS

What's the price per each?

I use the cheap set too. I've worn mine out after 10 years, so I'm due for a new set

Most of what you need can be done through techline

Thanks, I'll have to do some diving. I know there is a flex fuel discrete pin on x1-5, and in your 09 CTSv LSA, it's got engine oil temp, so I may have to get some more hpt credits, and have a play around. Would be very nice to add boost control options to factory NA setups
