Since the demise of performance enhancers...
Has anybody heard of someone else producing a closed loop ECU?

My dyno guy told me that they actually remove the oxygen filter on some bikes like the VTX when they do a custom map with a PCIII. They can't tune the bike to the best performance because the built in ECU senses a change in O2 levels and tries to compensate. Not good if you make changes to the stock configuration.

Toward the bottom of the description, it reads that a up comming Hyperspeed fuel module will use the O2 sensor and that this particular pipe has the provision for that sensor.

That's all I know about the Warrior and a closed loop system for it.[8D]

That was the so called system being devised with the Hyperspeed name by Perfromance Enhancers

I'm using a sensor on the Road house slip-on with a a/f monitor from K&N.
Computer: I relocate the intake air temp sensor,with a bracket, on a right spot near the tank at the chassis where it was the metal holding the coils(I have Barons relo coils)for fresh air and no heat. The result was black sparkplugs. Return it to his place at the Barons aluminium plate.

Good to know. I was playing with that idea. Thanks for sharing!

Monitor, not ECU. What does this do to enhance performance?

Computerdude explain it perfectly.
If you have a map downloaded from any source for your bike, maybe it run fine but not in all rpm. You could do it better knowing in what rpm and throttle position it is not working perfect. The monitor (not always)can help you when it changes it's a/f ratio. If you have a print reading from a dyno, you could even confirm the ups and down of your run with the maps number and your monitor. If you have a custom map, forget it. This is not the last coke on a desert but it can help you and looks tricky too.
