  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Possible to go from Map 3 to Map 2 - TE310R?

Husqvarna
AA Class
Hello, I just picked up a used TE310R which the owner did not know about any modifications to the bike since his shop buddy took care of it for him and I noticed the intake was plugged, cage was upgraded to the TXC version and that's all I can see.

I have now bored out the Velocity Stack and looking to also remove Cat soon, next step will of course be to go to map 2 or 3.

I'm not sure what Map it's currently on, so worst case is that it's already on MAP 3 and I switch it to MAP 2 with the Map Switch I ordered.

Best case is that its on Map 1, and I switch to Map 2 for a great power increase.

Any harm in going from Map 3 to 2?

When I got some extra moolah I would like to do pro circuit full exhaust + map 3 but this will do for now.
 
The map switch is just a "mud mode" switch to reduce torque in slippery conditions. To change maps from map 2 to race map 3, you need a HST (husqvarna service tool)

The switch is useless in my opinion and a waste of 30 bucks.

Thanks I'll be going with zipty for the 65 dollar reflash...

completely uncorked just need to remove catalyst and hoping map 3 makes a noticeable difference.
 
The catalyst comes out by hand after removing the muffler (it's in the junction of the header pipe & muffler). Often it is rattling around because the outer ring is broken. A 5 minute operation.

When Ty reprogrammed my uncorked '14 TE, it added 5-7 or more hp, I bet. I think the map that he uses is a modified TXC map; and I do not think they're switchable on-the-fly (in spite of the electrical schematic). But I've been unclear on the whole map thing vis-à-vis the 310r for a long time now.

In the past the re-map had to be done on the bike, and they (ZTR) don't have a donor bike hanging around much anymore I think. Maybe they have a TE wiring harness & sensors to fool the ECU nowadays, 'cause they seem to have gotten around this. Call ahead just to be sure.

The nomenclature map1, map2 etc comes from the 449/511 dash display; but WTH- it's a handy designation.

The PCV has switchable maps I believe. Johnrg has developed a few maps if you go that direction.

good luck.
 
The 13/14 bikes hold one map. They need to be reflashed with the HST to change. Map 3 works great but is a hair rich on the low end and why it pops a little and can be hard starting hot at elevation. The 13/14 bikes needed that GET accessory unit to get the Map switch and multiple maps. The PCV does that for me. I have the PCV with 2 maps, map switch and Autotune. The PCV offers a near perfect map after use of Autotune and I created a sea level and above 6500 ft. map.

As far as your bike. One can't assume the map. The bike could run fine on Map 1 as long as it had the TCX filter cage, as I ran it for a bit like that, but with the proper PU and Map 3, it's a dramatic change. Pull the cat, send in your ECU and you should be a happy camper. Make sure your intake manifold has been plugged. Also make sure you don't hear or experience a clicking sound and starter that won't turn the engine over. If so kick the bike or bump start so not to burn out the starter. The decompressor needs to function well and is an issue with these bikes. Just a warning as they may or may not be issues. If so it's a matter of going tighter on one valve shim to allow that decompressor to work and allow the engine to spin up more easily.
 
The electrical schematic in the service manual for the 2013 shows a race/mud switch. Are you sure that the GET accessory unit is necessary? What is the GET accessory? Is there an indicator in the display which map is in use?
