Stock o2 sensor 2015 XP 1000 w/ECU flash?

Hey guys,

I just sold my 2014 XP 1000 and bought a 2015 XP 1000.

I kept my Dobeck AFR+ and Muzzy exhaust from my ’14.

If I get my ECU reflashed and use the AFR+ will I still need to use the factory o2 sensor?

My Muzzy exhaust does not have the second o2 sensor bung.

I have heard that the reflash eliminates the o2 but not sure.

Rzr won’t start with other maps

I bought a complete 800 packard stage 2 motor with pc5 and autotune from a member on here . It came with 3 maps and I got 3 more from a Packard employe the deal is it will only start and run with the original map that came with the motor that he was using! I have sent the other maps to the pc5 and the motor will not start! What am I doing wrong? The map that runs is set for Kilopascils of pressure ! John

Dobeck gen 4

I have the gen 4 on my rzrs. It stopped working after some wet ridding. It either goes to full rich or full lean and doesn’t move. The lights are working showing the shift points when riding. You guys think the controller got wet? Has anybody ran into this and fixed it?

Vendor Request – ECM Re-Flash

I’m making an open request for any vendor to respond to this thread.

Of the vendor’s that re-flash the ECM — I’m asking for a complete list of all the parameters that you have the ability to change to include both the low and high parameter value and if that parameter can be disabled.

No pm’s — No e-mails — No phone calls .. .. Simply post the list to this thread.

I’ve gone the Bullydog custom tune route — My last option is now for a custom re-flash by someone competent that can perform — I wish to have a different outcome this time around.

If you wish to earn my business — Post the list.

I’ll be in touch.

Thank You .. .. 🙂
