Hi,

I've just seen that there is two new PC III maps available on the Dynojet site for R III European models.

M510-001 - Completely stock bike with Dynojet O2 Sensor Controller

M510-002 - Stock exhaust with catalytic converter removed and Dynojet O2 Sensor Controller

M510-003 - Triumph performance exhaust, Stock air filter and Dynojet O2 Sensor Controller

M510-004 - Jardine full exhaust, Stock air filter and Dynojet O2 Sensor Controller

M510-501 - European Model Stock exhaust Stock air filter Dynojet O2 Controller Fitted

M510-502 - European Model Triumph Performance Slip-on Exhausts and Catalytic Converter Replacment Pipe Stock air filter Dynojet O2 controller Fitted

It seems that there is some differences about the O² sensor.
On the U.S maps "Dynojet O² sensor controller"
On the Europe maps "dynojet O² controller fitted"

Do you have some informations about that ?

Thanks...

Hey Trackerjack..

I think that the " O2 sensor controller" and the "dynojet O2 controller" are they same thing, ie the device that you plug into the O2 sensor harness. This is a curious deal. I hooked an OBD II scanner up to my bike with the PC III installed and the O2 sensor controller fitted (which bypasses the O2 sensor) and I was able to pull up a reading for the O2 sensor and it fluctuated back and forth between rich and lean just as if there was an O2 sensor hooked up. This controller must mimic the actual O2 sensor but it probably changes the info the ECM recieves to fool it into what the PC III wants it to do...

This, however, makes no sense. From what I understand the PC III keeps the ECM in open loop... therefore the ECM doesn't even look at O2 sensor readings, but runs off of a predetermined fuel map curve. If the bike were to go into closed loop it would then start reading the O2 sensor.

I can only guess what difference, if any, there is between the Euro maps and the USA maps. I could understand if they were for France and Germany specifically as they have power restricting tunes....

You may have to email the PC III people to get answers.

Thanks Tomo,

I've sent an E-mail to dynojet and I'm waiting for the answer.

why don't you just download the euro map and use the map compare function and look at the differences? BTW, there is quite a bit of difference in the maps but I have no idea why

I have already downloaded the two maps for cat by-pass + TORS.
There are some noticeable differences and I think it's with low emission in mind.
I would like to know if there some differences with the 0² sensor reading.
