My Autometer and Brenspeed's Dynojet wideband were right on each other when I dynoed there last.
Also, Any tailpipe sniffer will be much leaner than an O2 sensor right near the header collector or manifold.
Huh?
Do you mean leaner? Rich a/f wont blow a motor, maybe wash fuel on cylinder walls a little. Lean will blow a motor because it causes pre-detonation of the fuel mixture.
I dont think you can guess what the a/f ratio is and assuming it is going to be way rich (or lean) would be a mistake...
