I know it is old... but check AutoTune box Power supply. I unplugged power connector for my my chain oiler on another bike to turn it off - the PCV went into limp mode and AFR was 99.9. I didnt know what was going on! finally sourced issue my Autotune was getting power from same connector as chain oiler.becoyote said:***** edit
It was the power supply. I wired it into a fuse block which apparently wasn't clean. Ground is now right to the battery and the power is tapped of the rear light back under the cowling. All is good. ::013::
Installed today and I am only seeing 9.99 as an afr which means something is wrong.
Instructions say either a bad sensor or I have it wired wrong. I double checked my colors on the terminations and they are good. Anybody have a bad sensor out of the box?
I disconnect and reconnect my terminations tomorrow.
Anything else to check?
AT200- is a single O2 sensor setup.Defekticon said:I've read through this thread and it was alluded to that using the AT-300 vice the AT-200 maybe more beneficial with Arrow headers and an aftermarket can. Can anyone confirm?
Do you just unplug the stock 02 sensors and run the two from the AT-300? Do you need some sort of sensor eliminators do trick the ECU?Gigitt said:AT200- is a single O2 sensor setup.
AT-300 is a dual O2 sensor setup.
S10 runs dual O2 sensors... best to run AT-300 as the Arrows also allows for Dual O2 sensors.
This is also due to the sensors position before the 2 pipes merge.
Generally if you are removing the factory O2 sesnor and putting in an aftermarket computer you do need to plug something into the harness.Defekticon said:Do you just unplug the stock 02 sensors and run the two from the AT-300? Do you need some sort of sensor eliminators do trick the ECU?
I'm somewhat confused. The power commander installation guide indicates that you should retain the stock 02 Sensors for closed loop areas even if using the autotune as the autotune will not control the closed loop areas. This seems pretty crappy, unless those table areas are being populated based on dyno tuning?Gigitt said:Generally if you are removing the factory O2 sesnor and putting in an aftermarket computer you do need to plug something into the harness.
Mostly it is an O2 sensor eliminator. But S10 uses the Included dual channel O2 Optimizer
S10 2010-2016+ model PVC is model: 22-041
NOTE Includes dual channel O2 Optimizer
http://www.powercommander.com/powercommander/powercommander.aspx?mk=28&mdl=118&yr=2649
The O2 Optimizer for this model controls the stock closed loop area. This area
is represented by the highlighted cells shown in Figure H. The O2 Optimizer
is designed to achieve a target AFR of 13.6:1. To use this O2 Optimizer you
must retain your stock O2 sensors (even if using Auto-tune).
It is not necessary to alter the values in the highlighted area of your fuel table.
If using the Auto-tune system do NOT input values in this area of your Target
AFR table.
bonjour a tous,
j'ai installé un PCV avec l'O² optimiseur sur mon S10 génération 1 EUROPE équipé d'un AKRA et d'un filtre UNIFILTER.
La carte proposée par DYNOJET ne me convient pas. je trouve la moto "brusque" maintenant.
J'aimerais que ma moto soit souple et que la puissance soit disponible des les bas régime!
Pouvez vous m'aider?
merci
