I see hurricane has now added a 1 year engine warranty to their 175 - 195 and 205 tunes . With Dave using the tunes on the race track he must feel pretty confident

Whalen got back, they are giving whoever paid 599 a in store credit for the difference which works fine for me.

Considering the PV3 is 399 without whalens tune, and all the capabilities of the PV3 without additional expenses, it's a pretty sweet deal.

The only thing that sucks is having to pay a $200 tune license for each additional vehicle you want to tune with the PV3. But dynojets canned tunes are really nice and come with the license for free. If you used the Gap flasher, you will have to pay hurricane or TD their tune license fee, which is two times or more the cost of the pv3 license.

So, if I read that all correctly. If I go with the whalen system for $599 I get their flashes along with the tool to flash it back to stock, or reflash with a new update if one comes along. Comparing to the hurricane, which is $485, but I send it to them to flash. Then if they come out with a new update or if I want to go back to stock, I have to send it back to the hurricane dealer again to reflash. But Hurricane has 175-190-205 tunes, and it looks like whalens are less than that. Does that mean that the whalen tunes aren't as fast or is it not quite that simple. It also looks like I have to do some clutch work regardless of which tune I go with.


The information is out there, but it didn't look like anyone answered you.

When it comes to stock component tunes, basically ignore the HP claims. It's just a name pretty much. The real information is how much boost it's running. If whalen calls his the 185 tune and it's running 16psi, and TD or someone else calls theirs a 205 tune but they are also making 16psi, then they are both making about the same exact hp. They can play with things like timing and tables, but you likely won't notice much of a difference between them outside of throttle mapping.

Help me out here fellas. The boost amount is only part of the equation. 16 psi doesn’t mean everyone running 16 psi equals the same hp. I understand that there are variances in Dyno readings but just because boost level is the equal doesn’t mean output is the same. I am open to input on this. One simple example....we dynoed a procharged stroker engine. We were able to make very close to the same hp at 12 psi of boost as 15 psi of boost.

fuel is the difference...

using pump fuel you cant do much with timing

"stock component tunes" same same.

Change components to get less heat = yes, less boost same or more hp

Pretty simple really.
Tune 1 You can have a 16lb tune running stock timing that was ran on a dyno in a controlled environment with 93 octane and maybe a bit of actane boost to keep knock away. Engine makes good power. Run that same tune out on the trail and it’s pulling 3-4* possibly even more timing. I have logs of this somewhere. Power will be down when ridden in real conditions. I have picked up almost 4mph in 1500’ by adding a bit of race fuel to a “16lb” flash.
Tune 2. Is also 16lbs but has been tested in the field and data logged for miles and miles running fuel from different stations with proper timing for available fuel quality. This sled would dyno lower than tune 1 but also outruns it in the field because it isn’t pulling any timing and not relying on the knock sensors to protect the engine.

Re video below: I had assumed all 4s sleds used wide band 02, I think I understand complexity of trying to write a safe tune especially if ECU is difficult to Crack as I hear the 900 Bosch unit is.

TD has wide band now for 998

Yes narrow band O2 sensors cannot monitor or adjust fuel trim at all throttle positions especially wide open. It relies on the mapping(tune) to adjust fuel and is extremely limited. This is a primitive design in the automotive industry. Obviously to do with manufacturing cost is why they are not on snowmobiles.

As the video shows, having a active wide band O2 sensor has so many benefits.

TD needs to use the brake Dyno to slow the run down over the sled brake but I think he had to remove it to add the additional weight..lol

This goes back to my previous post. Same boost level doesn’t mean same hp level. Once everyone runs a wide band then I’m more inclined to agree on the same boost levels equal same hp levels...somewhat as there is still many variables.

Back when wide bands were not a option in the aftermarket world I built maps for boosted automotive engines from scratch. Tons of things to consider doing it this way. The wide band 02 sensor has took tuning to another level as well as knock sensors.

wide band tuning is easy and cheap using pv3
the oem o2 sensor is basically for idle
