I have an ls3+6l80e out of a 2013 camaro. It plugs directly into the trans too.
I have one more question though for anyone who can answer. I bought the Speartech cable-x box so I can use my stock speedometer. It needs to plug into the "VSS" (vehicle speed sensor) in the plug into the trans. Does anyone know what pin number that is?

On a side note, I'm using Digital Dakota's STA 1000 to pull speed and tach info from the CAN. You just plug it in to the OBDII port and give it switched power and ground. It can also drive a cruise control unit.
If you need to do diagnostic or tuning, you just unplug.
You can adjust for any wheel / tire size / gearing, and speedo parameters, etc.
It was $100 or so on ebay.

Steve - The Gen IV TCC's are wired opposite of the Gen IIIs and older. On the Gen IV's, they don't receive power until the brake is pushed. Also, I'm running a 2013 Camaro SS LS3/6L80 with some aftermarket ShrifterSix paddle shifters and the Sport mode does work on mine. If you put it in Sport mode, the shifts are different (you can have whoever your programmer is adjust it the way you want). While in sport mode, as soon as you use one of the shifters you are in the TUTD mode. If you want to go back to sport mode, all you have to do is hold the + shifter for about 4 or 5 seconds.
brake switch must be used with a 6L80E/6L90E transmission
has to do with torque converter lock up and the fly by wire throttle body
this information is pertinant Gen IV with the mentioned transmissions.
I may have this wrong but
Like everything else in the world
trust but verify
go to Performance Systems Intergration web site and check out the instruction manuals for your particular application

I saw this on HP Tuners regarding the new 2.5 bar map program. I see that table goes down to 163 degrees.
"The new rescaled fan temperature axis will mean the fans will switch on at lower coolant temperatures than stock. If you wish the fans to operate at the stock on/off temperatures you need to modify this table."
I wonder if only that table could be downloaded into my E38? I will ask my tuner.

from what I have read on PSI, their instructions state that a 2 position

I looked up the PSI direction and it is as you say. Problem is, the directions with my Speartech say the opposite.....who to believe????

Looking at the GM diagram the fused 12v power comes to the open side of the brake switch. The diagram shows the brake switch in the open position. The blue/white wire(s) on the common side of the brake switch going to the proper terminals on the E38 ECM and to the 6L80 TCM.
So if the drawing is correct there would only be 12V on the blue/white wires when the brake is depressed. That is the way I read it. I will say I am leaving the door open on the subject.

More research points out that Gen 4 may be different than the Gen 3 as far as when power is off or on Gen 3 power on when brake not applied
Gen 4 power on when brake so
Hart rod post seems to be correct
Like to see wiring diagrams myself

Thats at least the 3rd schematic I have seen with them all being slightly different. However they all show the brake switch being normally open with fused power to one side and the other side the blue/white wire going to the fuse box. From there they split up to the respective terminal in the E38 ecm and the 6L80 tcm.

The design looks like it should have plenty of potential. Hopefully the dyno numbers are not to far off. Port matching will be a breeze.

No I have not. I can tell you that the 160 degree thermostat does not seem to make any difference driving around town. I will be taking a long trip to the dyno on Tuesday and will see what the termperature is out on the freeway for an extended period of time.
When at speed my IAT was at ambient even with the 195 degree thermostat. So for my purpose a change to the 160 thermostat may not be beneficial. Mainly because 192 is the lowest I can run my fans. I will give it some more time and see what happens.
