spyder is at Dynojet for power commander testing

[aka1004]

i just dropped it off and learned a couple of things besides getting free PC and autotune.

most of air to fuel ratio is done by a programable o2 sensor up to a set throttle position, lets say 60% and rpm, say 6000. tweaking by PC is done above that pre-determined range.

evoluzione's and juicebox o2 sensor does not do much(according to dynojet)

SE5 CAN be dyno-ed.
he explained to me how but most of it went right thru my head but dynojet have the right dyno equipment to do it and they have a way to get around se5 downshifting.

will post my impression after they are done. it should be a day or two.

Thanks for update and if you could find out are they using O2 sensors (auto tune kits) for each cylinder, so if I'm guessing right you'll end up with
1. Power Commander V qty of 1
2. Auto tune kits with O2 sensors qty of 2
is this the set up they are testing?:chat:

this is the answer from dynojet.


We are not monitoring both cylinders with the Auto although you could if you wanted to. We have checked both banks and they are very similar so there really is no need to monitor both.

Thanks alot which bank are they monitoring fron or rear, or are the sensing at the collector?

Thanks Jim:thumbup:

from what i saw while i was there, it looked like it plugs directly into factory o2 sensor plug. not at the mid pipe but the harness underneath the seat.
autotune will need additional bung to be welded on midpipe. i was gonna have them weld on the bung there is a chance i may be getting a new RS so i asked them not to.

Very good thanks for all the answers :thumbup:

I would love to know how they can dyno the SE5. As that would be some very valuable information for me to have. Keep us posted on the progress, as I have not placed my order for the JB Pro yet.

this is the answer i got from dynojet.

(Not sure if other dyno centers are familiar with this model. It has to be an ATV dyno that is either in the ground or someone would have had to fabricate a way to support the front wheel.

All you do with the SE5 is get it into 3rd or 4th gear and while the rear wheel is moving at speed you must remove the rear speed sensors. Once they are removed you can't let the engine go lower than 2000rpm or the unit will downshift and not let you upshift.)

i think he said while i was there, in order to upshift again you have to reconnect speed sensor.

Thanks for checking into this with them. The only part that sounds a little scary is removing the rear speed sensor while the wheel is moving at speed. Sounds like great potential for losing a digit or something.

picked up my spyder from dynojet:yes::yes::yes:
over all throttle response is much better, especially on low gears but i think i need to open up a little more on top end, especially on higher gears.
it accelerates like hell on 1st and 2nd, slows down a just little on 3rd and more on higher gears. guy at dynojet was talking about finding a compromise between mpg and performance and i think i need to squeeze over to performance little bit more. i will go back tomorrow and tweak a little more. i don't think i can put all the new found power on the pavement without better rear suspension anyway but most of my fun is in 1st thru 3rd gear so it will nice to get little more on 3rd and rest of gears will be fine. i sprung for the optional lcd to what's going on while i ryde.

compared to the gadget i had before that fed more fuel but same amount all the time, PC performed better on lower gears but not quite as good on high gears but i am sure it can be tweaked.

oh oh and two bros muffler sounds really really good without the tip but it's little too loud... not for me but for my neighbors and cops. the tip should be here on saturday so... and it looks better than i expected.

The Power Commander should tune for throttle position and rpm,(at least the ones that I've worked with), shouldn't matter what gear you are in. The map would be the same as it crosses the same points in each gear. It would make a bit of difference what gear you tune in, as the sampling sweeps take longer in higher gears. Are the tuning in 4th gear? Are they tuning manually, or using computer generated 'DirectLink" maps?

Another thing to remember, is that without ignition timing adjustment(and sometimes even with), you may not gain much peak horsepower numbers. The nice thing about a well tuned machine is that getting there is usually noticeably quicker.:thumbup: Most of the noticeble change in a properly tuned system, is in the smoothness and acceleration at middle RPM and throttle positions, where most of your riding time is spent anyway.......

i will have to talk to them but i know that autotune allows you to tune gears individually in manual mode. i think problem could be that it has such a wide pre-set perimeter that's not adjustable...

 

[jedd]

Very cool aka Thanks for all info is PC ready to ship yet or are they still testing?:thumbup:

 

[chascarpenter1]

Very cool looks promising.

:congrats:

That did not take long at all. Glad you are enjoying the new level of performance all ready.

Now, the question is, what all did you get? I see the Autotune box, and am assuming that is the PC box strapped behind it. Then there is the LED display unit. Do you have any plans for ditching the air box in the future? What air filter are you currently running in there?

 

[aka1004]

yes i have pc,autotune and sprung for the lcd. it's pretty good to see the air to fuel ratio according to throttle position but i don't think i wanna pay 300 bucks for it. he gave me a good deal on lcd. the other advantage of having lcd is you can load numbers of different maps loaded on it and change maps on the fly.
he was saying most people will do fine with just pc. most of work is done by o2 controller anyway. it has pretty set value until 35% throttle and 6000 rpm. now that range is not adjustable as it set by the ecu. what you can change is air to fuel ratio but it's not done at the pc but with o2 controller itself. outside of that 35%,6000rpm range or closed loop, you can adjust however you want.
one thing missing from autotune for spyder and few other bikes will be adjustability for individual gears. they can not get a accurate reading off of speed sensor on spyder.:dontknow:

i am using evoluzione's race air flow. he was saying on the dyno, it did not make too much difference from stock airbox and he was surprised by that also. i don't know may be its because spyder is standing still :dontknow:

pic 1 is a proof you CAN fix anything with duct tape.
i've been waiting for windshield from F1 so i can mold the speaker pods into those little wings on the side of shield.
i got some headlight covers too. i like the way RT headlight looks so i thought i would try to mimic them. may be paint a small area silver around the headlight and/or paint the cover itself black leaving a circle about the size of headlight clear.

Did they tell you the HP?

Did the dyno run tell you the HP? I looked in your post but didn't see it... but sometimes I can't see for looking. Thanks, ken

 

[aka1004]

i asked him for dyno chart of before and after. he said he will email it to me later.

 

[krb1945]

Please let us know...

the results. Thanks for all the great information above./Ken

dynojet was telling me that you really don't need to dyno your spyder. just use one of the map, dual two bros or single and if you feel you need little bit more or less, up the air to fuel ratio bit more or down depending on how you feel.
