So i am trying to figure out a calibration table to use to get my AIM MXL Pista to talk to the ICM sensor...does anyone have a calibration table that i could start with to see if this thing is even in the ballpark ? I am getting some strange mV readings looking Online at dashboard configuration...Pulling the last of my hair out here....

Here is some more info from an older thread

I just sold my last Iron Canyon yesterday. You can buy direct from them. I believe we set the resistance (adjustable inside Iron Canyon unit) to 320 ohms for 996 Cups, but you should probably measure your sender resistance with a full tank. Then you adjust the IC unit to 20 or so more ohms. Once installed, you build a custom sensor measuring the mV readings as you add measured amounts of fuel. It works pretty well. I'll be happy to assist if you purchase one.

Got it fixed, turns out the ground that was connected to the brown wire coming out of the top of the tank was not "grounding"...Moved the wire to a dedicated chassis ground and everything started working properly ! Thanks all for the PM's and email suggestions, RL is a wealth of knowledge !

For context, I know you guys already know this... but the Iron Canyon fuel level sender is a device that works with AiM or other dashes to show fuel level when using a stock type fuel level sender. Its a circuit that translates resistance into a 0-5v signal for input into the dash. It's low cost, good tech service and ease of install make it awesome.

If you have MoTeC you dont need it.
