DO1023 Posted March 16, 2021 Report Share Posted March 16, 2021 Hi all. I'm looking for some ideas on how to wire in a fuel level gauge for the G4+ Xtreme on the SW20 chassis. I'll be running a powertune dash and would very much like to send fuel level info via CAN do the dash. I assume I need to tap into the stock sender wiring. Anyone have any ideas how to accomplish this? Much appreciated. Quote Link to comment Share on other sites More sharing options...
Adamw Posted March 16, 2021 Report Share Posted March 16, 2021 The power tune dash doesnt have configurable CAN does it? You will have to get them to add a fuel level channel to the CAN for it to work if it doesnt have user configurable CAN.

DO1023 Posted March 16, 2021 Author Report Share Posted March 16, 2021 Adam, Thanks for the response. I actually reached out to Powertune and they linked the same post. They said it's possible to read fuel level via CAN and display it on the dash - which is great. I'm concerned about the above post because it doesn't seem that it's MR2 specific? I believe the SW20 chassis has some nuance with it's fuel level gauge. Maybe that it's reversed from the standard? I'm not 100% sure and unfortunately can't find the post where I originally saw that information xD Quote Link to comment Share on other sites More sharing options...
Adamw Posted March 16, 2021 Report Share Posted March 16, 2021 If it is a variable resistance sensor like 99% of road cars it will work fine with the info above. Quote Link to comment Share on other sites More sharing options...
DO1023 Posted March 16, 2021 Author Report Share Posted March 16, 2021 Great - thanks much. Curious question while I have you that came up from reading the above post. I'm actually looking to migrate from the 3sgte to the 2grfe. I have most of the wiring stuff sorted by combing this forum so thats good to go. I'd planned to continue to use my link 4 bar map sensor ( converting the 2gr to VE ) - is that possible? Eventually I will give it boost but for a bit it will stay NA. Is there any reason a 4bar map would be inappropriate for this setup? Quote Link to comment Share on other sites More sharing options...
Adamw Posted March 16, 2021 Report Share Posted March 16, 2021 Yes 4bar is fine with an NA engine with G4+. Quote Link to comment Share on other sites More sharing options...

koracing Posted March 16, 2021 Report Share Posted March 16, 2021 SW20 fuel level sensor has 3 wires - ground, varialbe level resistance, and a wire for the low level light. Quote Link to comment Share on other sites More sharing options...
DO1023 Posted March 16, 2021 Author Report Share Posted March 16, 2021 KO Racing! Thanks abunch for that. That low level light I don't need I can see. So ground and the variable resistance. So I just need to scale the table properly and wire in like Adam mentioned above? I'll get right on it! Quote Link to comment Share on other sites More sharing options...
koracing Posted March 18, 2021 Report Share Posted March 18, 2021 Page two shows the resistance empty and full so you can use that as a guide for setting it up in the software I would think. Quote Link to comment Share on other sites More sharing options...
DO1023 Posted March 18, 2021 Author Report Share Posted March 18, 2021 Thanks abunch - really appreciate that. Going to provision it this weekend Quote Link to comment Share on other sites More sharing options...
