Ok,
another electrical post from yours truely. This one is incase someone feels brave.
Disclaimer: I publish this information without any warranties, either expressed or implied. Do not use this post as the final say, use the FACTORY authorized repair manual to get your information! I am not kidding folks! This part if installed incorrectly will, if you are lucky, just crash your car and if you are unlucky, kill you. So you do this at your own RISK if you choose to use this information! This post is to help in gaining knowledge of electrical systems especially for standalone folks that CAN use this! This post is using a MoTeC Mx00 series ECU with the DBW option enabled to illustrate the wiring. Triple check with your EMS manufacture for proper support of DBW!
The point of this thread.
The parts are cheap, even BRAND SPANKING NEW! Especially in North America where GM parts inexpensive new and even cheaper when used. For example. The LS2 Throttle body is about $375 new off of E-bay. The Throttle pedal assembly is $100 at your local GM parts dealer. Probably cheaper elsewhere.
I have searched high and low to finally dig up the electrical schematics of the LS2 DBW system (Electronic Throttle Control, ETC). In short it is complicated but the complication is there to save your life It is a REDUNDANT system which uses two signal channels to control the server motor. If one channel fails you still have the other channel left to control the throttle. I was able to find the electrical schematics for the 2006 Chevrolet Corvette which is where this system is pulled from. All parts are new.
First the Throttle body, (pictures labled LS2-DBW & LS2-DBW2)
The throttle body is 90mm inside bore.
This thing is huge! And it should be as it is feeding 6.0L of engine
Also notice the side. No throttle cable, instead this beast is the latest generation of Electronic Throttle Control based TB. Why are companies doing this? Simple really. They can then govern the power output for the first X miles and then enable full power. All corvettes, BMW and Mercedes-Benz are employing this power strategy. Also it is easy to integrate throttle control into the traction control strategy.
The pinout assignment (MoTeC assignments in paranthases) for the LS2 DBW is as follows:
Pin A = Motor (Aux1, Fucntion 5)
Pin B = Motor (Aux2, Function 6)
Pin C = 0 VDC
Pin D = - Signal (TP2, this signal is inverted from normal ie, 100% - 0% when fully open)
Pin E = +5 VDC
Pin F = Signal (TP, Signal is normal 0% - 100% when fully opened).
The pin out for the ETC pedal (pictures labled 06Vette-ETCPedal & 06Vette-ETCPedal2) is as follows (when reading the connector with the locking tab on top)!
Pin 1 = +5V (TPD2)
Pin 2 = Signal TPD2 (TPD2, is inverserve of TPD, when TPD = 0, TPD2 = 100%)
Pin 3 = 0V (TPD2)
Pin 4 = 0V (TPD)
Pin 5 = Signal TPD
Pin 6 = +5V (TPD)
And you are done!
CAUTION: Be aware that the 2005 pedal LOOKS the same but the pins are not the same! In the 2005 pedal assembly, pins D & F are higher resitance value than pins A & C which is the exact OPPOSITE of the 2006 model Throttle pedal assembly!!
Of course you should always TEST to make sure you did not cross any wires or assigned the wrong output to the wrong pin (on three points, TB, ETC pedal and the MoTeC).
If you have ANY questions! Send me a PM and I will try and answer to the best of my Abilities!!
