  • 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 The previous version was outdated and no longer supported.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 Remap feels wrong

Hello all! New here, hope you don't mind if I just dive right in.

Took my new 350s with 7 hrs on it to my LBS to have them "flash" it. It felt like a vast improve on the parking lot ride. I got home and the first thing I did was install the BDSB exhaust cap. Now it's surging and popping terribly. My understanding was the EU map was richer and designed for a more open exhaust.

Would a re-flash measure and fix the problem? I'm just looking for a little more off-the-bottom pull for trail riding. (I've change to 13/48 and that helped a lot)

Haven't been able to reach the service tech yet.
 
Service tech had another go at it and it's all good now. Lots of bottom, snappy throttle and almost zero popping.

I am about two steps behind you... just got my ECU back with Euro FE map on the table and BDSB cap in a box. I installed springs front and rear and 13-49 sprockets installed last night. woot woot.

One thing I learned about the Euro FE map is that it is semi closed loop* and the ECU is more advanced than I thought. It uses the MAP and IAT sensors in lieu of O2 sensor feedback to make global changes to fueling during an idle reset so you are supposed to let it idle for 5min and then blip the throttle to the stop for any change you make. Try that to see if it self corrects. Sounds like it pulled a bunch of fuel to match the restrictive stock exhaust and now it is still running in that trim even though you changed the endcap.

*- it is not going to be as accurate as closed loop with wideband O2 sensors, or probably even standard ones like your car, but it is better than nothing.
 
I thought I read somewhere that the S models ECU's were unlockable and a add on tuner was the only choice or replace the ECU with the non S. Maybe I mis read that?

Believe only half of what you see, and none of what you read on Cafe Husky. ;)
 
Just did the LBL 200 and the bike was perfect! Throttle blips over mud holes and logs were child's play. I can't believe how much better this bike handles on rough single track than the old DRZ.

Yeah the tech told me up front that he doubted he could change the mapping. He said Husky told him it would just reset back to stock. He was able to plug in the FE map, so far so good.
