Pinout for side connections

[EricM]

Attached is the pinout for all the connections on the side of the ECU case.

Is there a legend equating the input pins on the side connectors to the input options in the software?

the CAN ADC xx are obvious, but the pins in the 22-pin connector are not, especially the VSS+/- pins.

 

[EricM]

I'll make one, but VSS is "digital frequency in 2", AUX VSS is "digital frequency in 3", the other digital freq input is the MAF input (or flexfuel), which is "digital frequency in 1"

Where do I source the green 22 pin connector? Its it suppose to come in the kit? Keep in mind in making my own harness and that this is not a grand national.

It's in my webstore: https://www.turbotweakstore.com/SearchResults.asp?Cat=30

What are you connecting to it?

 

[1937 Chevy GNX]

Alky and level sensor for alky. I was just curious. Figured it would come with the ECM.

 

[EricM]

Most people don't need that connector, so I don't include it normally. You may not need it either for controlling alky, unless you've used up the other inputs and outputs at other places.

Yeah I am still confused about that too. For example I was trying to make an extra gauge and there is a Canin1-8 or Canout1-8 so it's a bit confusing as to how to add a pressure transducer for oil or fuel. At least for me haha.. I tried looking at the Tunerstudio forums and could really find anything. I'm obviously missing something.

Tell me what transducer(s) you have, what inputs they are going to, and I will walk you thru setting them up.

I agree that it can be a little confusing at first. But once you set up the first one it all starts to make sense (and is very flexible)

That's great Bob, thank-you.
Well the two sensors I really want to understand how to set up are my Fuel pressure transducer on the fuel rail (Caspers 12v), and an Oil pressure Transducer mounted right near the outlet of the block (RIFE 100psi).

The FP Transducer(Caspers 12v) is wired to location B11.
The Oil Pressure Transducer(RIFE 100psi) is wired to location Canadc02

Once I get these figured out, that should help me so I can verify that I have my Alky pressure(Fueltech 300psi), Trans pressure(RIFE 300psi), Trans temp(RIFE), Ambient air temp(Caspers kit GM), etc set up properly.

here's a bad video about the fuel pressure input, forgive the audio

Also, here is pic of the extra inputs and their names in the software. This is already on your USB flashdrive and comes with every ECU, but I'll include it here too. Let me know if something doesn't make sense.
