Convert ETC to cable TB

[4wheelin]

here is one from holder crazy, it's for an 04 with a 6.0 but you could try a full flash, the pcm might accept it, if it does then just find a 5.3 of the same os and do a segment swap.

That was the one I tried but it is ETC, it logs TAC comms faults so is a ETC cal.

I found the wiring for the 1mb green plug pcm and it is the same, http://www.chevythunder.com/2004_gto...outs.htmwiring, so I switched in a 512 kb PCM by changing the plug locator things from green to red and lone behold the IAC works, the vehicle won't run as it is a locked PCM I am yet to return but I can see a test IAC motor step out on ignition on. I am using a 2004 GTO Pontiac 12587604 cal as it is the only cable operated 1mb one I have been able to find.
Question being can anything other than a stuffed PCM cause the IAC to not work. I can see the IAC-SUM dropping but the IAC does not move, odly it hasn't logged an idle control fault which makes me wonder if there may be a tune parameter I've missed. It idles at 1800 rpm.
Oh yeah and someone prior to me has TIG welded a mount bracket to the case.

I have to deal with a 4L80E trans as well so if anyone has the van cal that is 4l80e and cable in a 1 mb ls1 PCM that would be lovely.

I looked at the schematics for an 04 van and it shows the ETC and IAC wiring, so it might have been an option. if you want the diagrams PM me your e-mail and I will send them to you.

In looking over the various Calibrations it seems there are those with ETC in them even though they are cable, the diagnostic processes are different for the two, I am going to set up the diagnostic enablers as per a cable car in regards to TAC module communications, throtlle processes and IAC and see what happens.

That didn't work. Oh Well

Had the 512 PCM opened up and there were no IAC drivers. The Calibration went in and ran fine but no idle motor control, there may be 2 512kb PCM part no's?
