Hey im currently running the innovate wideband which is apparently the most accurate one out there, but i know most tune off the dyno exhaust wideband. how many points off is the innovate compared to the dyno method, im looking rich on the innovate and was wondering if the tuner just added more fuel for safety(sure he added some since it was tuned in the heat of summer) or if the innovates off a little. thanks.

 

Is your Utec Temp Compensation set right? The hotter it get the richer your wideband reading and that is why you need Utec to compensate for the temp which by the way Utec is marginal at best when compensating for temps. Utec temp range is from <1C - 50C so intake temp above 60C then Utec cant compensate anymore...

People say dyno wideband is accurate but most of them uses a tail sniffer which is way in the back. My Local tuner basically just deduct 1 off that reading to compensate. So who do you trust, the one that is 8feet away or the one 1 foot away?

 

subtracting one is bout right if the sniffer is in the exhaust
