Hi guys, can someone where to find the pin outs for the 2003+ 1mb (with the green plug).
Cheers Mike

PM me your email address
LS1_1MB.zip
I can't remember where I got this or if it is vehicle specific.
512k RoadRunner Firmware 12.14R
FlashScan V2 Bootblock V2.07.04 Firmware V2.07.22 EFILive V7.5.7 (Build 191) V8.2.1 (Build 181)

Thanks guys, email sent as well in case there are differences.
I am trying to get the 1mb PCM to work with cable throttle body but am having trouble with the TPS registering, When I hook up the 512 PCM it reads but not when the 1mb PCM is connected, so I was wondering if the pin location was the same???
I dont see it on the diag from mr.prick

Comparing a 516k & 1mb they seem to have close to the same pins.
C1 (blue 516k) 46 TPS 5V Reference
C1 (green 1mb) 46 5V Reference
C1 (blue 516k) 60 TPS Low Reference
C1 (green 1mb) 60 Not Used
C1 (blue 516k) 14 Throttle Actuator Control Serial Data
C1 (green 1mb) 14 UART Serial Data
C1 (blue 516k) 15 Throttle Actuator Control Serial Data
C1 (green 1mb) 15 UART Serial Data
C2 (red 516k) 24 TPS Sensor Signal Pin "C"
C2 (red 1mb) 24 Not Used

Yeh thats what I got....so how does the 1mb read tps as it has a sensor in the throttle body
I imagine thru one of the UART Serial Data pins.
Maybe C2 (red) 24 can be used like the 516k
I think another question is how will the PCM react without ETC,
aren't all 1mb PCMs ETC only.
