Fuel-It Flex Fuel Kit for the MT Supra

[Vicbespoolin]

I bought the Fuel It kit for my supra which came with the CANbus ECA option. I'm using MHD and wanted to read the ethanol content there plus activate flex fuel. My question is there a diagram that shows how to connect everything to the ecu with posi-taps since its a manual and there is no TCU connector. Thanks in advance

Yikes not looking forward to this. Didn’t know that was an issue.

I emailed BimmerECU solutions about this and said they send instructions with their open wire MHD kit.

Nice! My flex fuel kit if from Fuel-it and not the MHD flex fuel kit.

Could email them and see if they'll send instructions?

I recently purchased the MHD flex fuel open wire kit. Using MDH+. I’ll be doing the installation this weekend. Not 100% how to do it myself?

See below for wiring diagram. Instructions came in box.

Talking with burger motorsports since they installed one on their MT Supra. Hopefully it’s resolved.

Nice I went with the Fuel-It flex fuel kit which is the problem for MT Supra since there is no TCU connector

Looks straight forward. Let us know how it goes. I wanted to grab one during BF but no one answered my questions in time for the correct kit or if it came with instructions.

Did you see my link? Tap the twisted pair in the passenger footwell.

Just saw this! I will look into this option, they told me its the same way as installing a flex fuel kit for BM3. The video still shows tapping into the TCU connector which i dont have, so i might have to tap into the passenger footwell like you mentioned.

Do you have a Manual Supra? If so, was it just tapped into the DME?

Yes mine is an mt . It's tapped in into the main harness to the dme .. I followed the pinout provided with my mhd flex to see which wires to tap in.
