rb3 tuning

Rapid bike 3 can run up to 100% duty cycle same as Dobeck which is Purelogic, MPI, and many others are all the same with different programing.
RB3 is like having a stand alone system with real mapping.
A lot of guys are knocking the RB3 that do not have any knowledge about EFI.
If LOAD setup and Voltage is not setup to run in the map properly then the whole system is out of whack.
Add timing in the bottom end for quick throttle response and retard/pull timing with boost for more HP without detonation.
A proper map with also give great fuel mileage.
Even with Tuning Bike you have to know how to use it to make proper maps.
Anyone that has seen what we do with a sled using RB3 knows how much better we make it run.
I have always been a tuner since the late 70's on Motorcycles, snowmobiles etc.
We get a lot of guys running RB3 with a 2 bar map sensor and they need a 3 bar sensor to run over 15 psi boost.
You cannot run more then 15 lbs boost with a 2 bar Map sensor!!
Bring us your Boosted sled with whatever kit you have and we will make it smoke your buddies same setup hands down.

Wanna put money on that? I can show you a a mid mount and a front mount running 18-20 #'s with air/fuels in the low 12's on 50/50 c12 and premium. I've seen a 3 bar Apex that was set up on tune bike, worst running RB3 map I've ever seen.

All the fastest guys sleds run so good because they do all the tuning themselves. ;)
 

ON my t apex using rb3 I finally got some time to tune is properly and throttle response is crisp, punch throttle from idle it get full boost within 10ft.

Only probleme that stil remains... rb3 wont compensate altitute proprely.... that being a piggy back (but the best one.....)that is to be expected.

IF you are close to Daves shop the best way is with the Tuning bike module that Dave has. I just mapped mine this past weekend with his stage 3 injectors and it is silly sick now!!! HUGE difference!! Well worth the time I spent there!!

Powderlites is really on top of the RB3!!

Got the tuning bike on mine while in sicamous... did not work properly with tuning bike... so I reverted to a baseline tune... and rode it that way for reminder of our stay in sicamous.

I don't see the connection between a 'worst running apex' and the 3 bar map sensor.....



Nor would I try running higher than 16 or 17# of boost with a 2 bar... does not make sense.

I'm not saying the 3 bar doesnt work, I'm saying I dont have faith in the Tunebike, I dont think there is a substitute to tuning by seat of the pants using a/f as a reference? (AT ALTITUDE) All I'm saying is you can run the 2 bar above 15 #'s boost, we've done it. All depends on where your voltage settings are. Mitch had it close in the beginning, not sure why he changed? I have yet to see a 3 bar set up that runs well? Everyone I've seen has a blurble? Quantum Velocity has a great baseline 2 bar set up for the Apex that can run 18 +. I wouldn't go over 19-20 with it on 50/50. They need bigger injectors after that, who needs more than 18 anyways?
 
Looking at the maps in the rb3 section of this site... the tuning bike maps are not looking right at all... I would never tune my sled that way.


anyway, I've tuned mine very close to perfection, and timing/efi maps are not anywhere close to the shape powderlites posted.

Look at this video... (now having trouble with rev limiter hitting on standing start... have to back off a little then on again to avoid this)

http://www.youtube.com/watch?v=mNgSRr7z_No


full boost from idle with no launch system well within 10 feets. (with a big 2871...


Boost was 17# on this particular run,


I tested up to 21# but could not hold it off rev limiter (4 ramps only... )

Ok, now build us a perfect map for a nytro and I will gladly pay you for it (within reason lol)

My nytro runs pretty good, but it could be better especially in the bottom end.

let me know if you are interested in putting your talent to work. No hurry as our snow is gone anyway.

I dont have too much time on hand... habe too much projects ongoing from myself :-o

I only wanted to show it ps possible to do it with rb3, just take some time and testing, and not only dyno time.... dytno time will give you hp. but not throttle response and spoolup time
 
not trying to bash anyones product, but myself and my buddy took our rb3's off after several failed programs and the actual rb3 box failing meaning a tow down the mountain. after a couple ruined mountain trips i decided no more of that stuff. mines for sale if anyone wants to try make it work. 500 cdn with 3 bar sensor.
 
you may have a defective rb3?

But I must admit ... the rb3 programming software is buggy... I have had my fair share of problems with ..... that pos software.... so I know what you've been through...
 
i'm not sure what was going on, but the last time i used it in the mountains, i shut the sled off and it wouldnt start again, so i towed it down and had to rent a sled. ended up unplugging the rb3 box at home and it fired up. tried with my buddies software to see what was going on, and couldnt read the box. sent it back to powderlites, and they told me there was no program in the box, not sure how or why it just erased itself. so they sent it back, i hooked it up and the sled was so rich at 1800 feet, it was totally pointless to try it at 7000 feet. i'd rather ride a sled than play with the laptop on top of a mountain for a day, so the rb3 is sitting on the shelf. i'm sure some people have gotten it to work well, but i've been reading mixed reviews lately. imo, its a piece of crap, but thats just me i guess.
 
I understand.... I had to bring laptop on mountain just to keep mine running... Had no time to tune... I just kept it running at idle ant WOT... no midrange... was not as funny riding in mountain as it should have been because I had no trottle response.

Now that I tool some time to tune it... throttle response is crisp, but still won't be the same after na altitude change.... bad for mountain sled.
 
Tuning Bike is okay at best, we used it to get a sled running and improve the drive ability. But to properly tune you need a data logging system. We didn't care for RB3 at first but its not to bad after figuring everything out for yourself. We can have a sled running good in a couple of hours now. Have you guys checked the sensor voltage at low elevation & then again at higher elevation? If so what are you readings?
