TBI WBO2 Tuning- Dyno Results

[dave w]

I think the tread would wander off-topic if I provided the engine specs. I'd like the tread to focus more about WBO2 tuning. Tuning the chip for the correct AFR at WOT is essential for optimal performance. WBO2 tuning the chip for daily driving AFR's is a good plan too.

Understood, just curious...

Finally just got around to installing some new parts.new acdelco 4 wire heated o2.new knock sensor.new aem wideband o2 wired to read in tunerpro.I can say this.in 10 logs I've gotten a lot closer to feeling right than I ever got with out the o2.it's also left me thinking the tic I hear might be exhaust leak.great tool for tuning and finding other issues.feeling the difference between 14-15 afr at above 60-70kpa to 12.5-13.5afr at same kpa makes u really see what to do to get the response u think your adjustments make.once I get some more time I may try open loop afr tuning to see how far off that is.really wish I'd put thw wbo2 in sooner.

Daily driving tune results. Several data logs combined (with the same chip) showing over 179,000 lines of data in the screen shots.

The screen shots above are "Closed Loop" averages.

It looks like you're tuning with PE/AE disabled? I assume you tuned with WOT too?

The WBO2 Excel Spreadsheet is using Average IF formulas.
Average IF AE = Inactive
Average IF PE = Inactive
Average IF PE = Active (for WOT)
Average IF Closed Loop = Yes
Average IF Near Idle Flag = Yes (for Near Idle)
Average If Near Idle Flag = No (for Off Idle)
