Tune ECU. Laptop or Ap

I know this. It's just easier for me and the tuner to already have a bung available for his wideband. That way you wouldn't have to remove your current o2 sensor. Allowing the bike to correct part throttle A/F on it's own. This would also allow the tuner to see the changes the bike is making and possibly change the demand settings in the ecu.

I would never run an auto tune btw. A proper tune with the ecu itself should be achievable. I personally don't like piggyback fuel tuners if I can avoid them.

And I will mention my thought that, if the ECU is expecting only the fuzzy not too accurate narrow band signal, it will not know what to do with a wideband signal, if one is sent up. It will only likely respond to the signals that correspond to the expected range and will give totally inappropriate adjustments.

Who said anything about hooking up the wideband to the ecu? It would need to be hooked up to a wideband controller so that it could be hooked up to a computer of some type for data logging. Which is only really useful for tuning purposes or racing purposes which would lead to full time use. Pro racers datalog every run. The extra bung would be plugged up for daily use. Only used when adjustments to the tune are necessary.

This is how I have it on my Fox body Mustang. I have a fairly modified engine plus nitrous. So I run a custom tune. Any time I change something, it gets strapped to the dyno and a wideband installed for tuning.

It sounds like you have it all figured out.

Finding someone to tune with TuneECU in PA could be a problem.

Juice what software and hardware do you use to log? I have a wideband sensor, and have been considering doing the same thing.

I don't have anything yet. But the dyno software has built in datalog tools.
