  • 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 The previous version was outdated and no longer supported.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!

FE/FC Ignition map switch

Husqvarna
AA Class
Just a heads up, fitted a trail tech switch today (ktm sxf/xcf switch) and you no longer need to stop the motor to change the ignition map. The trail tech switch does have a separate momentary kill switch which you are supposed to wire up which also makes your OEM stop button no longer used.

will post a video later with the trail tech kill switch not wired up and you can hear the engine change revs as the switch is changed from stock, mild and wild on the fly (need the high idle switch pulled out to hear the changes in engine revs).

this is pretty cool as with the older KTM's you had to stop the engine to make the changes, by doing it on the fly allows even greater usage options.
 
Is there any suggested octane changes with changing the ignition mapping to the "wild" setting?
 
I noticed I can hear a quick burbble in the engine when I switch mine. I like the kill switch built in too. It was very easy to install and seems to work well for me. I've been running mine for 40 hours /1250 miles trouble free so far. While in wild mode my 501 revs out much quicker and the mild setting seems to only be right off idle making the bike seem to bog a bit but once you hammer it she will loft the front wheel and take off so at least on my 501 the mild is only affecting the low RPM range which is cool for tight woods or muddy conditions.
 
Reveille, do you have the trail tech kill switch connected up? do you hit it when changing maps?
cause from what I seen in the shed yesterday you don't need to do either.

I just went to upload my video but it has no sound, will do it again later on the wife's phone
 
I have the trailtech switch with the kill switch combo. Got it from sickass. The only time I touch the kill switch is to shut the engine off. The map switch will work with the engine running.

I've had my trail tech map switch installed for a few months now. I do have the Euro map installed on my ECU. Some times I feel like the Trailtech is working, and other times I'm not sure if I'm just imagining it's working or there is some kind of DELAY between the time you switch it and the next mode becomes enabled. One guy reported you need to let it idle for 10 seconds, then switch it, then wait for 10 seconds...so what is true. Aside from the fast-idle test, I'd like to get precise feedback on what throttle behavior changes you are noticing between MILD & WILD settings to be certain mine is working the same.

I still keep wondering if the switch works "on-the-fly" -OR- if you really do have to shut the bike off and restart it, -OR- do yo really need to let it idle for 10 seconds between switch modes... I've seen conflicting reports, wanna be sure. Thanks in advance for replies from anyone who has one and is certain its working. What do you know for sure? :)

Trailtech 3-way ignition-map switch on FE 501S:

1) MILD to WILD, what changes do you see off-idle to half throttle?

2) MILD to WILD, what changes do you see half-throttle to full throttle, etc?
 
Try doing this to seee if it works.
Pull out your fast idle knob/choke - then switch between modes, you should hear the engine revs/note change .
this works on my 350
 
I still don't have the truck tech ignition switch on my bike, the EC you is still locked on my FE 350, I cannot find a dealership in Oregon that will unlock it for me and install the euro map. I wonder if there's a way I can remove my ECU and send it somewhere to have them unlock it and remount the bike for me like halls are or zip Ty??? The stock ECU mapping works pretty well being on the lean side since I ride at high altitudes, but still want to change it

Zipty does the 501 ECU. It might be worth a phone call.

Just bought a 2015 FE 501 new from "Bills MC Plus" in Salem Oregon. He has the ECU map tool to do this. He just doesn't sell KTMs so had only experimented with it on the smaller cc size new 4 stroke Husky models. He just did my FE 501 to the Euro map and said I was the first one that he had done the Euro map change for on a FE501. Call him and ask for Bryan Or Bill, and take it to him. NO DOWN TIME. Cool.
You didn't mention if its a FE350 "S" model or not so it could be locked for good if it is. I got the 3 position map switch for the handlebars along with the headlights H/L, kill switch with the rear master cylinders basic banjo fitting brake light switch and direct plug in harness for legal lighting as a kit, minus turn signals from Sicass racing. It even has a puny horn. To make my riding buddies get out of my way. LOL.

Tried it. Nope, no change, no discernible "burble" either between standard/mild/wild settings.
 
My factory map switch is change on the fly, just says it won't actually switch until engine hits idle RPM's. I can tell a change more so in throttle response and in the soft setting makes it very smooth.
 
UPDATE:

Spoke to my tech. Bike MUST COME TO IDLE, throttle musts be all they way backed off BEFORE the switch will change modes between Standard/Mild/Wild on the open Euro map. XC-W green sticker map is not open.

And following this up from a issue with customer at the local shop, if you mess with the TPS it doesn't switch at all as it sees the throttle always open!

Interesting point. I never messed with my TPS since new or after the mapping. Then again, I never checked TPS values with the right tool to ensure it was set correctly by the factory to begin with.

May need to splurge for that KTM user setting tool at some point. For now, maybe I'll just have to get the TPS setting checked. Thanks for the tip.
 
I adjusted my TPS and the factory add on switch still works. I'm sure if you really crank the tps it won't work but then the bike will run bad so what's the point. I think stock is like .58??mines at .61 and works just fine.

No need for KTM tool if you want to check/adjust tps just get this http://www.tpstool.com/ that's what I use and works great.

Or save your money and use a couple of pins and stick them into the back of the connectors and use a voltmeter to read the level. Then go buy 2 cases of beer with the $ you saved and thank me later.:cheers:

Can you post pictures....maybe a procedure with pictures? :D
