I think I forgot to mention that in addition to converting the Miata fuel level sender to the GTO sender, the Miata cluster fuel gauge needed to continue to function. So basically we needed to splice the GTO PCM wire into the wire going from the Miata sender to Miata gauge. This presented...
We're still working on this and the vendor is helping us. It wasn't as simple as plug and play. We're going to modify the unit a little, per the vendor's instructions, and see if that works. Will update more...
Yes, time is money. Combined with the additional benefits of an OTS item as...
I ended up ordering a conversion box that I found for $45. yes, the other parts could have cost less, but I would have also needed to sort the correct parts, build a waterproof/shockproof box, and figured out how to program/setup the parts. So I went the easy route. Of course I have yet to see...
Cool! I now have a couple of variables to work with: offset and mx. I don't know where those are used at this moment, but I'll research the above widgets and hopefully figure it out. Thanks!
The expert video is hilarious!
Thanks, IRStuff. So something from here: https://www.arduino.cc/en/Products/Compare

That's getting a little beyond my skillset, but I can give it a try.
Constraints: it's an auto application, so 12 volts...
Thanks, TurboEng. The full mark is most critical because of the evap purge valve. If it runs with a full tank, it will suck fluid into the evap system. No bueno. But yeah, most of the time the tank is empty, especially the way I drive.
Thanks, Greg. I'll go that route if I can't find an inexpensive solution for the entire range, and assuming the ECU is happy. If it continues to throw a code, I may need to find a complete solution. What about an adjustable potentiometer?

I have already searched for solutions. I found this one, but it's expensive:

Hi,
I need to increase the resistance of the signal coming from the fuel level sender in a Miata going into the ECU of an LS2 engine. The Miata ranges from ~5 ohms (full) to ~115 ohms (empty). The LS ECU expects a range from 40 ohms (full) to 250 ohms (empty). Reading the full point is most...
