Anyone wideband a Pettit unlimited ecu?
 

Just curious what A/F's a person sees with this ecu. Is it in the 10's, low 11's, etc and what mods? If it's extremely rich, then a S-afc could be used to dial some of the fuel out and make a little more HP and still be safe.

Here's about the only A/F info I've seen for the Pettit so far:

thanks, I must have missed that thread.

My question is if you are running rich enough at 14.7 psi can you turn up the boost another psi and be safe? Also a little off topic; will the pettit ecu and m2 ecu support a single turbo or do you have to go stand alone (power fc etc...). Sorry if its a stupid question.

Another for ya...

This was at 10 psi, dp, cat back, intake, fmic, stock motor, turbos, cat, and fuel. Tail-pipe a/f probe. Disregard green run as probe had come out. Power sucks because previous owner had cut the CRV wire at the ECU. :rolleyes:
