1999 Porsche 996 Carrera 2

PostPosted: Sat Feb 02, 2019 7:39 pm    Post subject: Reply with quote

Theres some good books on EFI tuning about, I'm just soldering up a speeduino open source ECU for a carb to bike throttle body conversion project which I will map myself.

Production cars generally just have a narrowband lambda sensor than will only work at lowish revs (can't keep up). Hence why it does not have much effect up the rev range.

I will use a wideband sensor to map the engine on the road as I don't have a dyno. I might just leave the wideband in as it will be low miles car for full on closed loop running.
