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 The previous version was outdated and no longer supported.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

2013 TE 449 Power Surge Basic setup

Whats up Ladds?? Got a question. Just picked up the power surge for my TE and was wondering a good base line setup for my bike. Im on the East coast and Im running the bike with a slip-on and no other mods. I helped my friend set up his 2012 511 last summer but I didnt know how far off the two bikes would be FI wise.
Thanks!
 
Refer to it as a JD tuner.

Above pick is my r&d on a dyno tuner. Lean the idle to 2 and adjust the air screw to 3 3/4 out for less back pressure. these numbers are on my 12"
 
Thanks tho, guys. I put it on today and revved the bike and my two 3 year old girls screamed and ran away and then yelled at me. Will have to tune it when Im not on their schedule haha

Can you define back pressure? Not sure what you mean by that.
Thanks

When you close the throttle and coast the engine will not slow the bike down as much. The idle and air screw setings are key to decrease flame outs and the 3 3/4 turn out and 2 on the JD idle worked great last Sunday for idle to bottom end transition.
 
The stock maps are too lean from idle to 1900 rpm. To compensate for this, we adjust the idle screw to add more fuel. Ultimately, changing the map would solve this issue and allow you to idle at a normal speed and still have a tuned system. So far, the only way to do this is to replace the ecu with a powercommander 5.
 
Tip.... When you tune you idle only do this when bike is fully warmed. I like to put the bike on a center stand and run fans at the radiator and exhaust so you can tune as long as you want without over heating the engine. Very slowly open the throttle and listen to the exhaust note. You can hear the bike start to increase exhaust note and "sence" if it's struggling for air or fuel.... Sometimes too much fuel and not enouph air. I tweaked mine for more air and less fuel at idle and this seemed to make a really smooth idle increase
 
Well I did the air screw adjustment today. 3 3/4 out from all the way in. Bike idles like its "cammed" if that makes any sense. Like a big block Chevy motor. Granted, I had high test gas with no ethanol in the tank because I dont ride the bike much lately with the crap weather. Anyway, its about 25 degrees out and the idle was high at stops and suddenly dropped to normal. No backfiring on decel tho and the power...holy crap what a difference from stock exhaust and "race map".
Pretty much finished with the CRF 450 exhaust too. Turned out nice IMO. image.jpg
 
I have same problem, but only when riding, when on stand I can't replicate it! I've played around with the air screw but haven't found a solution! The 2 your talking about, is that the yellow/blue?
 
Is there a stepper motor in the fuel circuit which keeps the idle up for a short period before droping down to normal idle?
