I'm working with the AiM MXL Pista data logger and dash. Pretty sophisticated system. So far things have been working pretty well. I connected it to the Megasquirt ECU, and it seems to communicate well. I haven't fired the engine yet, so I haven't been able to check all functions. But, so far, so good.

Except for one thing - the fuel level sensor.

I installed the sender converter from Iron Canyon Motorsports. I followed the directions (pretty close) and recorded the data as I slowly filled the tank.

But I can't get the dash to display fuel status. Does anyone have a good sensor configuration they could send me?

Did you ever get a good configuration? Im wiring in my ICM converter today.

No, I have not been able to get it to work. But, I havn't messed with it much, either. Should have been a simple process, but....

Well, I'll let you know how mine goes. Mark sent me a file with the mV readings for every half gallon, going to enter those in tomorrow.

If it works, I sure would like to have that file.

As soon as I get confirmation I'll let you know.

Any updates on this?

No luck yet. I entered in the values but didn't get a readout, but that's as far as I went. This winter Im going to dedicate some time to the dash now that I fixed my laptop screen. Not sure if its the values that are incorrect, but I'll probably start with doing my own 1 gal fill readings and see how they compare to the ones Mark gave me.

Its been low on the list but along with figuring this out, I also need to get the speed sensor adjusted to get the speedometer corrected. And get the gear indicator functioning. I've just been having too much fun driving the car!

So I finally put some time into this today. Up until now I have been getting a blank readout for fuel level with everything connected. I had the custom sensor entered into channel 8. This time I moved to channel 1 and now Im getting a numerical value. After transmitting the data to the dash (with about 2 gal in the tank) Im getting a 7 gal reading. Drove to the gas station, filled up and it reads 12 gal, as it should. So it seems the max mV values in the table are correct but the minimum ones need tweaking for an NB. The excel file I was given was for an NA so maybe theres a difference between fuel tanks. Another issue might be that my battery voltage is a bit higher than the guy who made this chart.

ICM Fuel Sender

Yes, thats what Im using with the miata sending unit.
