Need help with juice box problems

I'm not sure about the plug readings.... but from what I've heard the only possible way to get an accurate reading is to get up to cruising (cursing) speed and then hit the kill switch.... coast to a stop and check the plugs.


Yes---- the Aerocharger setup is $5,000. The first production units are shipping out this week.

I don't expect the price to drop at all.
 
It sounds like it all started with a too lean fuel mixture. Being too lean may cause increased cylinder temperatures which in turn could damage the spark plugs... especially if there is no ceramic past on the threads to help pass excess heat off the plugs.

It also sounds that the mixture is still too lean when running in stop and go traffic. With increased temperature you need a little richer mixture to help cool the cylinders. Gas just like water/antifreeze mixture is a coolant.

IOW increased temperature in the internal cylinder head in the area of the spark plug may be causing that area to glow red which will cause pre-detonation which will rob performance, power, smoothness, idle... everything suffers with too lean a mixture... including mpg's.

If you've had the updates... it may be as simple as riching the mixture a little more... each :spyder2: is a different machine... what works on one may be real close on another:spyder: but not exact. Ken krb1945
 
hopely when there are more spyders around price will go down.
i am all for 40% more hp but not at 5k plus no warranty on powertrain at least, i am guessing.
it's not only 5k for aerocharger but will need 1000 dollar shocks also.

goodbye to the warranty for sure..

While I would also be concerned about the warranty, remember that here in the good ol' USA we have laws--- and the manufacturer has to show your modification caused the failure.

That alone wouldn't keep me from doing this as their system continually monitors the whole thing so that engine damage should not happen--- but they can't obviously monitor excess wear on your drivetrain.... but many of us thrash these bikes really hard and probably are causing excess drivetrain wear just running as stock.

Towing would also cause excess wear... heck... the turbo kit might actually allow the Rotax to NOT run as hard for tasks like towing.

The main thing keeping me from doing one is the price tag.

If it was $3,000 I would have one already... but $5K is a bit hard to justify in my mind.... but man does this look like it would be fun!
 
Well i finally got the chance to pull out my plugs and wow they are straight black and smell like gas.

Thats with two bros stock settings on the JB and my Two bros dual...Still stock airbox. My settings are as follows

1 (green) =.5 - i know this one does matter
2 (yellow) = 2
3 (red) = 1
4 (green/blue) = 6.5
5 (yellow/blue) = 4
6 (red/blue) = 4

I know as bonecrusher said he starts at 3 across the board and goes from there. How will i know what my sweet spots will be. Im taking it just by looking at my settings know i need to come down on setting 4? any suggestions would be great i dont want to run to lean and mess things up but i certainly dont want my new plugs to look like this after a tank. Thanks a lot guys

Wow...yeah...the first thing I'd do is can your stock air filter and get something that lets in more air...get a green filter or K&N or somethin'.

I think you can bring 2 and 3 up a little...keep 4 pretty low as this is your 'cruising' setting...I don't see the need for this one too high unless you simply want to have backfiring while riding and burn unnecessary gas...for 5 and 6, according to Fire, make sure they are different or they can apparently 'short' each other out.

I do believe each bike and each mod. require individual tweaking...like I said before, I start around 3 for all and modify accordingly. I look for good performance and if I get any backfiring from the exhaust, I lower the setting when it occurs...for example, I used to get backfiring while decelerating from 5th to 4th gear...and then cruise...I lowered this down and this seems to have stopped.

I just got the 2nd update so I have to go through the process again...it's fun to tweak it...I make a change or two...run a tank of gas, and then make changes, as necessary. I think I can dial the best settings in within 3-4 fill-ups...

Ordered a Kewl metal on Wednesday im hoping it shipped out Friday so i will have it this week.... im deff going to lower setting 4 and i did have the decel popping issue not sure if you would consider it a backfire but its sounded pretty embarrassing. Im going to lower my setting 4 to 3 and bring up 1 and 2.... seeing as how low one and two are going any lower then what two bros had wont hurt anything correct? also when you say you dial in your settings are you checking the plugs after a tank or going by mpg and butt dyno... i cannot wait to get this airbox outta here. when it put it back in i did however remove the 2 rubber tubes that suck in air and am running a big hole in the airbox. Thanks bone crusher for giving me the crash course ill let ya know how my ride goes tomorrow. ill do your setting 3's across the board and see how it goes.

:agree: Setting 4 is for cruising.... should be lower than 2 and 3 as they are for Accel and full throttle. For sure gotta make 5 & 6 different from each other.

When i posted that i copy and pasted from my pervious post. That was the first thing i did i set 5 to 3 and 6 to 1. deff going to cut down 4 i cant wait to ride this thing again.

I keep my 5 and 6 higher...remember that the lower these numbers, the faster the injection for throttle and max throttle...I don't know the millisecond difference, but I keep them a bit higher...4 is the one that seems to affect the mileage the most, at least for me...

Well i finally took it for a ride... put settings 2 & 3 at 3 and moved setting 4 down to 5 . This seemed to take away some popping i had on decel at low rpms. going to make sure i don't have an exhaust leak. Also going to move 4 down a bit more until the popping goes away. This is what i was wondering where did you guys mount yours to play with it... i have to take my panel off everytime. Which isn't a big deal as its only a few screws but i didn't know if i could fish it out of the plastic any way. Also how will i know when i go to lean... im still dumbfounded that two bows put setting 4 up so high with the results that i saw on my plugs im glad i didn't leave it there any longer haha.
 
All I do is lift the seat and fish out the controller. I'm still playing adjusting on mine. Using bonecrusher settings I was still getting some backfiring on decel. The next fill up I'm going to use MM settings and see if it's any better.

I put mine under the plastic piece that the tank bag sits on...put velcro in there and it fits perfectly...I simply take off the two plastic tabs, adjust as need, put it back, put the two plastic tabs back in, and good to go...

I don't like it under the seat, but that's just me...I like it tucked away and hidden...I think Lamont has his here too...

Can you list what the MM settings are?

Curious.

I'm running good with these settings: 1-, 2-3, 3-2, 4-5, 5-1.5, 6-4. Like a lot of you I still get some popping on decel especially on hot days. I have replaced the y gaskets with the Honda ones. I have just installed the 02 modifier from Evoluzione. Before I report on it I'm going to run it for awhile to be sure of what I have. As we all know Mother has a way of interfering.

Drop your number 4 setting and see if that affects the popping/backfiring...it made a difference for me.

I just had the second update so I have no idea what I'll end up with now...

:agree: Having the #4 'cruising' setting higher than the #2 and #3 'acceleration' and 'wide open throttle' settings doesn't make sense to me.... you want more fuel on accel and WOT.

Mine is running pretty good--- but still has a 'glitch' every now and then when de-accelerating... gets 'caught' between modes and stumbles. This is much better than when I had modes 4 & 5 set the same and the JB got confused and would cut the engine on acceleration/WOT.

I've heard that 2 Brothers 'laughed off' the idea that having settings 5 & 6 set the same would cause problems..... well--- to this I say they have obviously not ridden a Spyder with those settings set the same.

Nothing against 2 Brothers, but realize they don't make these units. They are made by Dobeck Performance.... who was originally the co-founder of Dynojet/Powercommander... but they went separate ways. Dobeck also makes the Aerocommander used for the Aerocharger kits.

Not saying one is better than the other... just that 2 Bros. is re-branding the units (just like aerocharger is doing) and probably doesn't know as much about them as the actual manufacturer.

I'm leaning towards getting a Power Commander with the Auto-Tune setup---- after they get the kinks worked out.

I didn't want to say anything yet but so far with the 02 modifier I have no popping issues but lets wait awhile. Now 2 bros. recommends a higher #4 setting than 2&3 and with my machine no matter where I set the other settings mine seems to run best at 5 and over for setting 4.
