The really tough part to get for them was the rear steer position sensor, but it's been...

I have a subscription to this thread, as I have an '03 GMC 1500HD with QS. So thanks for updating -- I can promise you that *someone* is reading your updates!

My build is much like yours, and I...

Posting this because I just got through installing e-fans in my '03 Sierra a few weeks ago. I did *not* encounter the listed issues as described by the OP. Although I will say that if A/C is...

OP; I have this exact same truck (except mine is a GMC), including the Quadrasteer. Mine is a 2WD w/ 4.10, corrected for 31" tires.

You might try looking up a Lingenfelter TRG-002. It's a box that allows running a 58x / Gen IV engine with a Gen III controller. Basically, it spoofs the crank / cam signals.

Also, if I...

Can't help with the 3 bar, but as far as the sw version -- you should be able to d/l the 4.x beta, install it on your machine alongside of the 3.x version if you want, and then use 4.x for evaluating...

Subscribing, as I have a TBSS and TB sitting on the shelf waiting for an X-Link (or better yet, whatever this forum comes up with to duplicate it's function)

Appreciate the reply. Just some follow-up clarifications / info, while I finish the pump.
