Polaris Powersports Support Now Available!

[jaz|TUNING]

I just ordered HPT as I am tired of DynoJet's lack of feature and terrible customer service. I'll be using this on a 21 XPT, to start.

And I've been asked if I tune HPT for so long, I figured I should learn it and support it.

SOME 20-22 Pro XP cannot be read via OBD. If you have the Blue 02 sensor cover. Cali edition. it will not work TPROT is active.

Bench read only for full file and EEPROM.

There are 43 Variations of the pro XP OEM calibration I have identified so far.

tune alone I've had these to 194 rwhp with zero other mods 106 mph 20.5 psi. 167 rwhp stock 87 mph

Few more load limiters to address. throttle cuts back to 60% at 200% load once we are past 102 mph

anyone locates that hex address. lemme know. I mod the Hex dump. Here's a stock brand new 2021 OEM pro XP bin file if your curious about what's in the actual unlocked code.

Attachment 118456

The blue O2 sensor is a WBO2, which is on non-CA models as well.

I would like to make just a few small adjustments. 1. stop the annoying false misfire codes. 2. after putting on an K&N filter and aftermarket assassins muffler, it keeps throwing me into limp mode with the same misfire codes. Just a little guidance would be nice, for Christ's sake everyone wants $250+ just to help each other out. motorsports and racing folks used to GIVE each other thousands of dollars worth of parts and knowledge simply for the fun of the sport...boy are those days gone! This forum should be a group of enthusiasts sharing tunes and tricks for FREE! wanna help?

There is a whole misfire tab under engine diagnostics you could check out. I assume engine roughness tables would need to be adjusted. im not sure what the changes need to be

disabling the DTCs under the DTC tab might solve it completely there are 3 there. that might solve it or still go to limp mode with no code displayed. that route might be risky if you develop another issue and the misfire detection is disabled

Do you have a thread started with your stock read? That's what most never do. They come asking for help, but never take the time to post a read of their ECU. Hard to help without it.
