$780 shipped for harness and computer no pedal
Would this factory ecu need to have a vin installed for HP tuners?
Can drive by wire be removed / programmed out?

I just ordered the LS7 harness kit from Scoggin Dickey.

I would also like to know why my OBDII scanner did not work. I have a ScanGauge, which is a simple scanner/code reader, and it was not able to communicate with the ECU. My L92/L76 intake with the LS7 cam did fire up immediately using the LS7 harness.

OK guys sorry for the delay. I got some time this weekend and worked on the LS3. I was not able to download the file from the PCM. The HP Tuners gave me an message about the VIN being incorrect.
I did a search on the HP Tuners forum and someone had got the same results when they tried the LS7 Harness. I posted my info and what I had heard from some of my contacts at GMPP. Bill at HP Tuners informed me that at this point in time we cannot tune these PCM's
The OS and the VIN are specific for the intended use on crate engines in pre emission vehicles. There may be a fix in the future but there isn't a time frame for this to get done.
Harness and controller does a very nice job if you want to install an LS3 crate engine in an older chassis.

yes please update.. I would like to use This harness and add the rest of the wires for the o2's , tank pressure and purge solenoids for a catted vehical.
if it can truely be reflashed with the CTs-v vin. and become a Cts-v ecu with emmisions control.

GMPP harness Was wandering if there were any updates on this LS Engine Control Kit From GMPP. Came across an 07 LS7 longblock awhile back for $3000. The block has a few problems, hopefully they can be fixed. Plan to put the motor in a 62 bubbletop if/when I find one.

24x reluctor Possible? This looks like a nice option for those with a 58x reluctor Motor..
Does anyone know what my options are since I have a 05 GTO LS2 motor with a 24x reluctor?
Looks like a pain to swap the reluctor out and I would like to hear some suggestions and costs related to the path chosen...if anyone can speak from experience I would appreciate it.
I know junk yard is one option but I found its not easy to find the harness and other peripherials without havng to buy the motor with it..
and considering Im planing on keeping the ETC function for cruise functionalit...manual throttle control is not an option.
Any input would be appreciated..
Thanks,
Matt

May have found the answer After doing more research it looks like the path of least resistance is to go with a package from Howell Engine developments..
Since I dont have a tool nor experience to remove \ swap the reluctor wheel coupled with the cost and labor of the cam sensor \ timing chain- cover swap needed... it didnt make sense to me.
Grand total for everything... Harness, ECU, Tach module, Pedal..including mass air flow and 02 sensors is 1675.00 not cheap but best I found for the scenario I have ( 24x reluctor LS2 ) since I cant seem to locate one at a junk yard..
Unless someone else has any better ideas.. This will be the route I will take..

Yes that was me. We had to load a VIN from a '06 CTS-V with GM Tech II tool and then we were in business. We used HP Tuners after that to tune it. I was worried that some of the connections in the bulkhead connector would not work after all this, but all of the ones I'm using are still working. The VSS output somehow changed because my speedo was reaing way high after we flashed the ECM over to the new files and I had to recalibrate it. Other than that is was pretty much trouble free.
