RE: Nitrouscontrol module for gen2


greg, is there someone you want this p-n-p harness to go to or just send it back to you, btw, it worked great...smile

Hi all, I have been setting my Busa to run nitrous over the last few days and reading and re-reading this thread, I am using one of Nicks (GSXR1300) spray bars and a NX lighting solenoid with a #20 jet (to start with) I was reading some of you were testing with 0 RPM settings....how do I set that up so I can test without riding? I have taken the bike for a ride with it all set up and came away underwelmed......I wasn't even sure that was working? So I would like to test it without having to acuatlly ride the bike.

cheers Nathan

gear on, use activation method yiu have chosen, e.g push button and turn full throttle. Olenoid should open when power on but engine not running

What was bottle pressure at activation ? Bottle mounting position ? Siphon tube in or out ? A/F reading at activation ? confuse Curious as have set up about 5 bikes with spray bars (tarantular type) and worked spot on every time without a prob confuse Caution when testing make sure you don't give engine a gutful of NOS then  hit starter

Bottle presure was at 900psi (zex regulator) AFR's were around 13:1 before nitrous injection, in the end worked out (rather embarressed about it to be honest) what i though was the "on" position for the actvation switch was actually "off" all good now. second test was a little more eventful. now to move onto a 30 jet

Thanks for the responses guys!

OK #30 jet installed, all working very well. 900psi bottle presure 2 degrees timing pulled out in all gears 50/50 injector ballance map, i used 50% duty in 2 nd gear with no ramp rate (yet) with 10% fuel added. 3 rd gear 100% duty with 17% fuel added (thanks Matador for the setup info you posted) bike pulls STRONG. its either lifting the front wheel or spinning up the rear wheel, either way awsome fun, very happy, need to get the bike to a dyno for fine tuning and some power figures!!! forgot to mention AFR's sitting around the 11.4- 11.7

Thank-you Petrik for this awsome tuning tool!!

No probs re "Dyno" more than happy to check your set up for you. smile
Not sure where your located I'm two hours north off Brissy and quite familiar with Busa/ NOS systems  nod.gif

Grizzly you would know of Ross Lemberg then ? Did two of his Gen I Busa's on NOS.
Also sponsoring the Palmyra big drag meeting early next month also.
No probs give me a yell when your ready to roll. Cheers

I know of himm, they have some fast bikes spoke to a rider of one of the Busa's in question at a meeting just after you tuned the bikes they spoke very highly of you. Bikes ran damn hard all night.

I know I'm out of my depth tuning this bike of mine but am enjoying doing little bits at a time, however a visit to you will be inevitable, already got the itch to go bigger on the gas!!! NOT GOOD!

I encountered a strange thing today while playing with the bike, I had about half a bottle left presure was 900psi I had the bike in second gear which was on 50% duty cycle with no ramp in time, I had tested this yesterday with no problems and great results. Now today I had changed nothing and in second gear when the gas came on i could hear the engine pulsing with the solenoid as it went up in the RPM.........has anyone else encountered this?

The solenoid is a NX lightning series (15100L)

Voltage fluctuation ? The solenoid draws around 10A.

Just installed nitrous harness. no issues, and I could send back the NOS progressive controller. Thanks Petrik and Greg.

Set-up a 40 dry shot, did preliminary testing, all went well. We are dynoing it Monday, going to save copies of the graphs and will post.

How was the gauge reading the gear ? Any possibility that the leg was resting against the lever and there is a shifter connected ?

In case the gear is not detected by ecu currently the ecu defaults to gear6 values. That we can easily change if e.g. first gear is felt to be better ?

I am not running a quick shifter or air shifter, and everything seemed to be normal.

Engine pulsing can mean many thing,s e.g. that the 10A current draw from solenoid is disturbing the sensors.

If you have innovate or some another fast WBO and enginelogging to check out the ground differences and injector voltages we could figure out more by reading the datalogs...

Just a suggestion:

now that data logging and auto tune gone so far can we add a safety net feature like stopping spray when the afr turns lean when we use dry systems?

I had that safety based of AFR in earlier version of boostfuel. Not really practical as using shifter caused a lean peak and that cut of the boost pressure causing some pogoing and at minimum FI light being lit up. Also when turning throtte full of caused lean peak and another reason for FI light to be turned off. Of course we could synch the AFR and shifting and try to estimate the time when AFR is not used - but dont know how practical that would be.

is there a way we can set a min and max speed for nos activation to go with tps and rpm? want to activate spray without button and spray in 1st gear

Jason,

You don't have to use a button to activate, the toggle switch on the harness i built for you once flipped does the same thing as pushing the mode up button.  so as long as you program in a duty % for nos in 1st gear, have the switch flipped, and are at wide open throttle and in the programmed engine rpm range she will spray :)

Greg

right, but say i have rpm set at 8500, don't want it to come on that early in first, so if i set it higher say 9800 then i wil probably drop lower then that when shifting, if i had min and max speed with rpm and tps i can adjust first where i want it to come on.

The nitrous control allows you to program a low duty cycle for first gear. This will allow you to leave with little to no nitrous addition, then increase as you go down track in the higher gears.

I believe you can just put in 40% duty cycle but have a long build time in ms and it shoudl be very soft.

ok, i want to spray 20% with 0 build time at 10k rpm in first as a starting point, it would be easier if software had additional parameters. if not i will figure out how to hook up a switch to the speed sensor that will trigger mode button

This is the 7.9s bike we are talking about ?

My approach to this kind of requets is: If there is a professional racing team with a commitment to test then I am more than happy to work to improve the ET:s - but would like to avoid adding just nice to have features which just adds complexity from a tuners perspective.

On our racing bikes we used or plan to use the following to control the gear based power:
- Gear based STP opening
- Gear based nitrous ignition retard
- Gear based autoshifting with preload

So far the nitrous activation rpm per gear has not been a bottleneck for our tuning or plans - but I am eager to listen the reasoning why and how it should be implemented... ???

no, that bike has a daytona sensors nc-2 controller, this is my first gen 2, it is a street bike for now, run a spray bar with 4 #22 jets, using my tuning experiance from nc-2 it has a min and max mph to go with tps and rpm.so i can look at speed and as long as i am in my tps and rpm window i can control nos activation. ie- rpm 8000-11000, tps 95%, 60mph. then i could activate initial shot at a higher rpm then 8K. not trying to waste time, i personally like this feature, does anybody else? i can post any info about bike, hp, et, etc.

Sorry - of course its gen2. Your the first to ask this if my memory serves me right.

Have never thought of tps activation as a result of speed which effectively the rpm/gear is. To make this kind of enhancement for next season I would need to better understand how the rider benefits from the feature and how the tuner uses it to make the bike faster. I still think I have not fully captured the full perspective for using rpm/gear activation - so if you dont mind, more ellaboration would be appreciated.

This would be fairly easy to ad, but certainly adds complexity to the nitrouscontrol module. The complexity is what I want to avoid as we are dealing with a freeware community project and therefore need to have a very useable product from a tuners perspective. Its so easy to get distracted by adding features and forget the whole key point (at least to me): "Make our bikes go faster with an easy to use products from a tuner perspective."

the sooner i can add power the faster i go, i can't add 30hp @ 8K in first gear but i can at 9800 in first i will go faster then not spraying untill second. i have a hard time finding mode button. thanks,

jason

Our experience says that direct power add will cause wheelspin, therefore rampup time was designed.

Hows the gearing on this bike, does it really get below 9800 after a gear change on other gears ?

Sorry for basic questions and comments, but really would like to add why this method is the best.

I like the way the ecu editor nitrous control works, and it does for me every time.
I use a launch limiter set at 6k rpm nos is activated at 6500 with a low duty cycle and ramp time in first ( it takes a little time to get jet size and duty cycle right) no ramp in rest of the gears just keep building duty cycle thru each gear.


Well done Petrik !

So reading al this I have a 40 shot spyder sys. on my bike, I can set up the ecu to only shot say 10-20 in 2nd gear and 30shot in 3rd and 4th.

Yes. It may not be quite as linear as that, but you can certainly bring the power in smoothly. Then, in teh fall when you get tired of that little shot, you can pull the engine, mod it, and use this to control a 100 shot

ok dynoed the bike and got 178hp and 105torq turned nos on with a 40 shot spyder system at 50% duty and 16% fuel and got 205hp and 125torq now I think I just need to tweek it, have my buddies with dyno thinking about tuning with ecueditor now.

airshifter can be a pain to setup, unless there is a pressure switch on the rod. the nitrous should be pretty straight forward push and go as long as it has been properly set up in dyno.

Hi all, I have been experencing a problem after updating to the latest version 2.5.5.26 , after i flash a tune that has the nitrous control active the bikes runs very lean at idle and runs rough. You deactivate the nitrous control from the tune file and re-flash and it runs fine, everything back to normal. Any idea's??

To my knowledge nothing has changed with the nitrous control for some time. Could you try creating a new stock bin file and copy over the settings including nitrous control and see if the problem is still there?

no ideas really. like justins says only things changed lately is with shifter and dsm display settings.

please send the problematic file to info@ecueditor.com to do a quick compare of the programming code parts of the file.
