Yes there is.. I just put on my Supertrapps with 18 mm bungs with reducers for the 12 mm OEM's. Are you thinking I can take out the front O2 sensor and put my wide band Wego in there and take it for a ride and record data that way. If I do, is that going to set a hard fault for the front O2 sensor not reading the AFR of the front cylinder?
And will it change the way it tries to add fuel when in closed loop..?

Another question is, can I put wide band O2 sensors in place of the narrow band sensors and will the OEM ECM read them?

 

Should just throw a code and run off the charts without O2 feedback, does the Wego only use 1 O2 sensor?

To run widebands you would need a Target Tune or one of the old Auto tune Pro modules, which is what I have for my PV

 

Ok gotcha.. I only have a single O2 Wego.. so basically if the ECM doesn't see the front O2 sensor producing any readings it'll basically go into limp in mode and then run directly off the program tune. Which at that point should be open loop.. Am I correct in assuming that?

Yeah I thought I'd have to get a piggyback unit to be able to run wideband...

 

Try it and see what happens, you're no stranger to experimentation

 

We'll I didn't know where to get the signal for the tach connection of my Wego to the bus . Last thing I want to do is blow out one of my computers.. so I brought the bike down to Rosa's for a Dyno tune... Like I posted earlier carbed is not problem, EFI is a totally different ball game.. When I pick it up I'll post the results of my tune..

 

Picked up my bike yesterday and here's the Dyno sheet.. Very surprised at how low the numbers are.. I truly thought with my build they would be higher.. just to note the cam is a TW 5-6..

Is that tuned or just a pull?

How does it compare to others with that cam?

 

It was a full tune and was told it was as lean as 16.:1 very lean up to 2500 rpm.. They did a full tune.. it runs very smooth and feels real good.. By what I've seen is easily 10 low on both sides... It really doesn't matter though.. It feels great.. still pulls the front wheel off the ground grabbing 2nd gear..

What concerns me is that these numbers are of what a cam only upgrade would look like..
I have 1.90/1.61 ported heads, with CCP at 195, Supertrapps, I would've thought higher.. Done chasing, it does go real well..

 

If your happy with how it rides numbers are irrelevant, ride it like you stole it and beat it like it owes you money

Just heads, no pistons?

Have you checked cranking compression?

 

I do get my money's worth out of it.. lol...
Yeah just heads, no pistons..
compression was set to 10.16:1 with 197 CCP.
