Minimum needed to run S5 engine on stock ecu
What sensors need to be connected for the S5 ecu to function and not go into limp mode? Theres a reference in this thread https://www.rx7club.com/forum/showth...ht=minimum+ecu
that S5s need more than an S4, but it doesnt say what they are...

I need this since I'm using the stock ecu as a stop gap until I get my stand-alone ecu sorted, and I'll be using a custom wiring harness.

Thanks, that was just what I was looking for.

I assume the pressure sensor is necessary also (this is a TII)?
