Some of you may remember the AFR Tuner I fitted a while back.
Well I got an expansion unit for it some time ago that runs 4 wide band sensors and will self tune individual cylinders.
I've had a single sensor in the mid pipe for long enough and I can't imagine the fueling being any better than it is.
BUT... I'm told the difference is night and day by a mate that's done this to a few bikes in Germany.
I was also one of the ones that hassled Tamas (designer and builder of the AFR Tuner) into making it run 4 cylinders individually after seeing some custom tuning on some race bikes with Motec ECUs.
The short story .... You can have excellent A/F Ratio in the mid pipe but it can be any combination of rich/lean cylinders that give you the right average over all.
This expansion will custom map each cylinder while you ride.
Now all I need is a welding guru to weld the fittings on and wire this bad boy up.
I know it's a sickness but I'm really interested to see how much difference there is between cylinders.
Not sure it'll make more peak power (would be cool if it did) but the part throttle and mid range is where I expect to see improvment.
Will try and post some more "installation" photos as it progresses and some results.....
