Kev's O2 controller or dynojet O2 controller?
 

Hi
I'm fitting a PCV and autotune to my xtx, I already have kev's fuel mod and O2 controller but I will move them over to my wife's MT03.
My question is, which O2 controller is the best or do they do the same thing? Do they have the same AF target?
I surely want to have the best option on my xtx ;)

Best regards

By the way, welded the auto tune O2 sensor bung today, hopfully it will work fine.

My controller runs richer than Dynojets O2 optimizer in the closed loop on a completely standard bike. Same bike same day, one test right after the other, the only thing changed is the O2 optimizer, O2 controller & just the O2 sensor no PCV or map change.

Dyno Jet only claim their O2 Optimizer targets 13.6:1 with a PCV fitted with the open loop mapping in the closed loop area set to +6, testing one device against each other on a completely standard bike with no map the Optimizer is 14:1. Increase the open loop +6 in the closed loop area on the cruise my controller will show a closed loop A/F ratio of 13.2:1 & Dyno Jets O2 Optimizer will show 13.6:1.

Took my xtx to motrac in Ellesmere Port, I had asked Kev which one was best, the dyno man was sceptical and said he would have preferred the dynojet one,
However when I went to pick it up he said he was very impressed with Kev's one and even called me a couple of weeks later to see if he could get hold of one for another customer of his :tongue11:

My Controller has been Dyno tested many times over the years & have a few Dyno centres around the world that buy & use them on quite a few other bikes besides the XT's, I have a big market for the FZ/MT09's, it is not fools gold the controller really works well & makes your XT660 ride so much smoother at part throttles.
