No I gotcha. I was just adding some further background/history to the poor performance of the Mack with these guys.

This particular video is very unscientifc but these guys have had the Doo 850's and the Mach up in Cochrane weeks prior in a number of vids and put a lot of km's on them and switched drivers around and the consensus is the same -- the 850's are faster off the line for sure and very close top end.

Attached is the map that was on my used PCV I bought a couple years ago. It's the basemap for a Hurricane 190 Viper kit. User beware. This was likely created in '14 with the kit and ECU upgrades have happened since then with changes to stock ECU mapping. I found it lean in multiple areas...

A good inexpensive set of communicators are the Lexin B4FM from Amazon. Couple hundred bucks for a pair. My son and I use them from sled to sled. Battery lasts all day in all temps. Can leave it in intercom mode the whole time meaning you don't have to push a button -- just talk back and forth.

It's a slippery slope Se7en. It starts with an inexpensive sled that gets you back onto the snow and then you're hooked and are spending 9 months of the year wishing it was snowing and thinking of what the next ride might be. Lol. Been there. Similar story. Grew up on sleds that we spent...

Yup I had the same combo on a turb Viper. PCV, Auto and POD300. Awesome way to tune for safe WFO and add in a little fuel economy in areas. The only problem with the system is that without access to a dyno I could only rely on butt dyno when it came to trying to wring a little extra...

I would find it hard to not ride with a GPS now. I find it so useful knowing time, direction, when a next trail is coming that we have to turn at, how long is this straight stretch, etc.. Having your travel history display as well is super helpful coming back across a lake for example at night...

Autotune starts as a blank slate. Up to end user to set desired AFRs.

I had a used Hurricane 190 kit a couple of years ago. I believe I have the map that came with it. It didn't work well for my '18 because I believe the PCV map was created when the kit was first sold in '14 and didn't compensate for future ECU changes but it was a good starting baseline. I...

I used this kit on my 2018 RTX this year. Didn't need any additonal oil. You should be good.

Hey Se7en. You will be fine with a USA only maps device. When you load the Trakmaps onto the device you will actually be turning off any other maps. Trakmaps runs all by itself and doesn't rely on any other maps. The current Garmin I run is a Nuvi 65 USA LM.

Check out this vid from Sledaddicz. They just put SnowTrackers on their Mach. They feel it transformed the sled.

Glad she's alright Cannon. That's the most important part. Had a few close calls with my son last year. He was try to keep up with the pack and he was too new to the sport to do that. I told him to relax and ride at a pace he:s comfortable with. I stay back with him and we have...

As someone that has been looking around at possibly having a Sidewinder in the garage sometime in the future (not now with these crazy prices) I can attest that I would easily spend $500-1000 more on an equal sled if I knew it had warranty. You never are 100% sure when you buy used and I'd at...

Great to hear there's another convert! I use the SkiDoo Ultimate Trail balaclava. It is long enough to tuck in around your neck to prevent drafts and it leaves your face open but can cover your chin on cold days.

If motor smooth it sounds like belt too tight or primary issue and it's engaging/grabbing.

Wow. As a colourblind guy that chart is a nightmare! lol. Let it snow.

Not a tuner either but played around alot when my '18 RTX was Hurricane turbo'd. Here is a ballpark of what I worked towards with tuning, autotune and datalogging. AFR targets - 1/4 throttle and below --13 - 13.5 - 1/2 throttle 5000rpm 12.5 - 3/4 throttle 7000rpm 12 - WOT 11 I found...

Some maps here. https://ty4stroke.com/forums/rb3-pciii-other-efi-maps.75/ Do you have a base map? If so you should be able to set your desired AFR's in autotune and let it do it's magic and build a personalized map.
