STILL boggin-kinda long- please help!! lol

ullose272 · Dec 23, 2012

so ive got a 2010 m8, it bogs between about 4000 to 4900, seems to be worse when coming off continuous throttle, like cruising down a trail, let off to go around corner and get back on it it will bog/almost die, but it will bog at random somtimes. it started doing this begining of last year after i installed slp pipe set, power comander v, and mds weights and speewerx spring, bdx oil injection delete. before installing this stuff i had bdx intake and slp silencer and there was no bog. this year i installed some boyesen rage cage reeds hoping to help. no luck. so here is my list of mods.
-slp pipe set
-pcv
-bdx intake
-mds weights/speedwerx spring/shift assist
-boyesen rage cage reeds
-oil delete

so ive got this bog, i had a racin station map loaded last year and told him my problem, he revised it and it was a little better, but still some bog, so i posted on here and got some ideas of what to look for. i removed tss, installed new grip heaters and wiring and switches, adjusted the exhaust valves. all with no luck.

last weekend first ride of the year- still bogs seems worse than i remember last year, rememeber i installed rage cage reeds over summer. so i say what the heck and load up an slp map for giggles. bog is terrible after riding today with slp map. so im going to load the racin station map back up but it was bogging last week just not as bad.

what am i missing? seems fuel related but the racin station map isnt adding much fuel? any ideas

and i dont know if it matters but my key has been replaced with a tether. could the tether be acting up?

ullose272 · Dec 23, 2012

the best way i can describe it is, like an accellerator pump that isnt working,

Unplug power commander and with caution see how it runs. I know alot of guys at elevation running this setup with no programmer.

ullose272 · Dec 23, 2012

i ride 5000ft and up what elevation are you guys riding?

adjust your belt deflection, its extremely critical to prevent engagement or just after engagement bogs....and make sure you have correct throttle sdjustment for proper free play on your flipper..approx 1/8

ullose272 · Dec 23, 2012

is the throttle adjustment for the tss because it is removed

that safety in the throttle block that you hear the faint click when ya play with the throttle that shuts the engine down if the throttle freezes..is that removed or bypassed..??

ullose272 · Dec 23, 2012

its removed,

m8magicandmystery · Dec 23, 2012

then how is your deflection

ullose272 · Dec 23, 2012

ill have to check and adjust when i get back to the cabin. i do know its probly been 300 miles or so since i messed with it, but im pretty sure the bog was there when the belt was new and adjusted.

My buddy put on the Slp set up on his 2010 M8 last year and we spent the entire year trying to figure out his bog was really bad around the same rpms that your describing. Try all sorts of things to fix it. The only thing we found was putting on a 2011 m8 ecu on and cured the entire issue. Luckily the dealer we work with was cool and able to pull some strings to get his ecu flashed to the 2011.

I was reading this hoping for the cure as I have the slp pipe and can and the ktx weights and have the same bog. Mine also will die sometimes after shutting it off and then restarting, it just dies like you turned the key off , then will restart. Problem is mine is a 2011. I have cut the TSS wire so I run a tether but was wondering if the computer is thinking the throttle is stuck so it shuts it down for a moment..????

ullose272 · Dec 24, 2012

anyone else have an issue with 2010 ecu?

ullose272 · Dec 25, 2012

any other ideas?

kidrman · Dec 25, 2012

Have you tried taking the SLP pipe off? You can the see if it is the PC and/or the pipe and go from there..

ullose272 · Dec 25, 2012

i dont have the stock pipe anymore.

WyoBoy1000 · Dec 25, 2012

I'm pretty sure its a mapping issue, if there is some way get the '11 mapping.

Is it a bog that throws you over the bars(hollow sound) or a slow gurgle then go. Whats the difference in the slp vs racinstation map, did he add or remove fuel.

One thing to do sometimes is relocate where the baro tube runs, (not likely but may help a little)

Check fuel pressure, if you wanted to you could put on a regulator and prob tune it out that way.

Sometimes wrapping the pipe will do it or restrict it a little more, (try stock can)

Just need to know if its dieing from being lean or rich more than anything. Maybe a little less octane depending on what rich or lean.

What oil are you running, if your running amzoil start there

m8magicandmystery · Dec 25, 2012

could your smart valves be acting up after storage..??...??..moisture issues that restricting the screens...just throwing it out there..

here is an interesting thread on smart valve issues on the 2012...

WyoBoy1000 · Dec 25, 2012

I would be tempted to add a large bolt to the end of the stinger or muffler to increase back pressure, I heard of quite a few '10's doing this with a can..
So either increase heat(wrap) or restrict it will increase pressure.

STILL boggin-kinda long- please help!! lol
