Power Comander + DynoJet Auto Tune

Hey there 2 questions. I have the opportunity to buy a power commander 19-003 and a Auto tune AT-300. What im wondering is will the power commander work with a 2013 Rzr 800s? Is it worth putting them onto a stock rzr? Will it benefit me in anyway? I can get the pair for $300.

Looney Tuned Programmer

I installed LT dual exhaust and the LT programmer. I haven’t touched the settings, so they remain on factory. Only been out a couple of rides since the install and pulled my dip stick for a check. My oil is full of fuel. Is the programmer not set up correctly? Or am I doing something wrong? I am guessing the programmer is dumping too much fuel in and it is passing the rings and valves, cause I also pulled my air filter, and smell gas. Any suggestions?

Power commander5 auto tuner need help

Hi
I have 2013 Rzr 900xp
I install the autotuner and change the target from 0 to 13 AFR.
I drove the vehicle for awhile then I find a new value in the trim table, then I accept the value according to the manual.

Do I need to accept the trim data everytime I find new value in trim table because it resets the value to zero? If I do another drive I find new values in the trim data.
Do I have to accept again or does it automatically go to the fuel table?

I have found that after I have accepted the trim data after a third drive it doesn’t always show the new values in the table. It still reflects the data from the previous drive. Is this normal or do I have to change the values in the fuel data manually?

What is the fuel ratio for 2,600 above sea level? Is there a table available that shows the various fuel ratios and altitude?

Does fuel type make a difference in inputting values. I’m using premium gas 91?
