ok some findings here i used the last editor to test down button and works well but when on 2nd gear the solenoid stays closed on 3rd pulses like it should on 4th pulses again don't know why as i set it 100% on 5th and 6th stays on as it should be.

based on your screen shot, it should pulse in 4th as you have a 2 second ramp rate.


So it should start at 70% duty cycle (previous gear's setting) , then 2 seconds later be at 100%.

Now 5th and 6th gear should come on and stay on

This sounds similar to what Butch is saying, perhaps something got messed up in the latest nitrous code, not sure hopefully Petrik see's it, or if someone else could confirm this is happening to them.  I know for sure when nitrous code first came out 100% would come on and stay on, no cycling.

Send me the .bin to ecuhack@tikkari.net and will look into with the desktop ecu.

The gear based nitrousmodules 1-6 are the same so this is not necessarily gear 4 related issue.

got it, thanks - will look into it. may take some days as i am middle of a building project.

already took some time and with rampup = 0ms it should work fine, but rampup is not tested on real bike so therefore will appreciate all information and feedback on this.

i just reflashed it with all settings the same but turned pair on and it still pulses but now pulsing every gear. another thing i notice is my gear position indicator changes while i hit the button. like if i'm in 6th and hit it, my gear indicator shows 3rd while its pulsing.

Pair should show pulsing all the time when pair is on. Pair needs to be off for proper operation - this was just for validation.

Tested all the gears and everything seems to be operating as per .bin. E.g. 4th gear pulses for around 2sec and then turns fully on. I Think that this is again one of those things where there is more into finding whats going on...

ok i tested with many different set ups i found out that when you set ramp up times it doesn't work and the 2nd gear doesn't do anything.
if you set ramp times to zero everything works fine all gears.

matador, if you set your ramp times to 0 and your nitrous duty to 100, does it pulse or just turn on and off? thats the problem i'm having it always pulses.

So to me it seems everything is fine with no ramps selected anywhere.

As soon as you add ramp features is when things start acting funny.

Everything below was tested using 2.2.0.12 downloaded this morning.  Just using a relay and LED wired into PAIR, I have a gps sensor I connect to the bike so i can just rotate it and not have to actually shift gears with the trans.  All done with engine off,key on, holding throttle wide open, then clicking up or down button (last couple I did with up button activation)

Test #1:
Gears 1-5 Pulse always (4-5th gear shouldn't pulse always)
Gear 6 stays on solid


Test #4:
Gears 1-5 remain off like they should
Gear 6 does nothing, should come on 100%


Test #6:
Gear 1 off like it should be
Gear 2 doesn't do anything (should pulse)
Gear 3 pulses
Gear 4 pulses always (shouldn't always pulse)
Gear 5-6 stays on solid like it should


Test #7:
Loaded nitrous basemap with no ramps, all works correctly


Test #8:
Gear 1 off like it should be
Gear 2 doesn't do anything (should pulse)
Gear 3 pulses
Gear 4 pulses always (shouldn't always pulse)
Gear 5-6 stays on solid like it should

Two things to get feedback...

1) If you guys are testing with engine at 0 RPM that is not putting rampup function on as it should. Thats was intended more like purge function. To be able to test using rpm=0 setting I would need to redo some of the programming logic. Maybe anyhow worth while just to be able for the users to understand how rampup works.

2) If there is rampup from 60% (gear 4) to 100% (gear 5) that should pulse and then move to 100%.

yep - I need to integrate the rpm=0 and real rampup stuff together. Never thought it being used for testing this way.

The ram up activation currently is the following:

if (((DSMbuttonpressed) || (buttonactive != 0xFF)) && (ECU_RPM > minrpm) && (ECU_RPM < maxrpm) && (ECU_TPS > mintps))

In case this condition is not continously met then the rampup will be reinitiated. Now if for testing purposes there is a need to activate the rampup at RPM=0 then I can change this to:

if (((DSMbuttonpressed) || (buttonactive != 0xFF)) && (((ECU_RPM > minrpm) && (ECU_RPM < maxrpm)) || (ECU_RPM == 0))  && (ECU_TPS > mintps))

I think this could work for testing for you guys ?

petrik if you would like it tested besides on the bench i will certainly test for you if you want to spend the time with the code, if you feel its fine I am good with that too.  Looks like our current test method is flawed LOL.

ok it is working i did some real drive testing and it felt like it is working on the road.
so i guess it is time for me to go again next week on the dyno with this set up to confirm it.

anyone else did any testing?

Ok.....Now I know I'm Not going Crazy Here!! Thats why I could NOT duplicate what some of you where saying....thought I was Losing My Mine Here confuse lol

As I do Not use the "Ramp up" Feature(well Not yet anyways) and always test going down the Road, and My Noid was working as it Should(On/Off). Makes Perfect sense Now with what you said above.

Thanks Petrik!

works perfect from what i can tell now ;)

Anyone else feel free to let me know if you see this at all, but seems when i go  between the gears i get a quick blip of the solenoid, like if its turned off in 1st gear, from 1st to second i can get a quick 1 pulse, was originally thinking its seeing 6th gear setting or something, but also tried 6th gear with no nitrous on, then repeated and think i am still seeing a quick blip of nos output between gear changes.  Running out of time to investigate more, maybe someone else can take a peak.

Its possible that you get the bip when the GPS sensor is between gears. If that is the case I will just add control there that when ECU_GPS == 0 Then nitrous is not active.

Name: Hayabusa ECUeditor for K2-K7, K8- and BKing models
Version: 2.2.0.15
- Nitrouscontrol module 2.08, when gear in neutral (e.g. GPS in between gearshifts) nitrous is not active.

This quick blib is interesting. I dont have bike at home to test with real gearbox so need more info on this. Into the latest x.18 (nitrous module 2.09) version I have included that when at neutral there is no nitrouspulse.

Obviously when testing you always need to reactivate the nitrous or any other module, else the old module is used.

After a gear change the duty cycle gradually rises from the setting of previous gear to the setting of the current gear. As a starting point is the previous gear value.

Is it a lot of work to make the nitrous cut off setting a bit finer ?
eg : would like to run nitrous to 11600 Rpm and then rev limiter at 11700.
The current adjustment is in 500rpm increments.
This is for Topend Racing , want to see if I can go faster than 340 km/h with stock motor and a bit of oxide ! biggrin

For i = 5000 To 12500 Step 100 done and published 2.2.0.20. It generates quite a long list. Let me have what you think.

Planning that DSM is going to be fixed and buttons reserved for other purposes than changing maps in the future. It would be too risky to let the users put nitrous or boost on with modeB or modeC.

Most dyno shops dont like the idea that they need to tune 2 x 3 maps (MS0,MS1 x A,B,C) and if not tuned then the B and C will not be correctly tuned.

Rather just focus on putting accel control steering etc. to the DSM buttons than just changing full maps.



Petrik -

I believe this explains mode A only with nitrous control?  On one Gen-2 we are using the pair output  activated by ECU nitrous control on one side of a DPDT switch and on the other side the Bazzaz map switch.  I've got 2.1.0.62 and the nitrous works well with teh Bazzaz providing simple data logging and mapping.  The issue is now we can't use the other modes for index racing.  Is there any way around this?

Thanks for all your work.

Dennis

After setting nitrous module you can set the mode abc to normal.

my personal strategy is to focus on slew rate controlled ignition in a few weeks to give us a kind of "anti slip" feature that slows us down. maybe we can consider having index racing tools for that too.

Just MHO Here, thinking out loud Kinda.......
I would have to agree with what Petrik said in another Post about "ABC" Switch being locked down in Nitrous & Boost Control Modules(Maybe altogether with having ms0/ms1??)do to it would be VERY easy for a "MELT DOWN" or at the very least Poor Running engines, if one isn't Very careful in what their doing! Now I know Most of us are Pretty Knowledgeable on what can Happen and know how to avoid it......also Just like Me, I also think "Most" want the absolute Most tuning Possible, But sometimes discretion is the better Part of Valler. I for one Love the Idea of using abc for additional features, and think with having ms0/ms1, with separate Nitrous and Boost controls is MORE than enough "MAP'S" to Play with. A Dyno tuner is already gonna Pull his Hair out with that..... lol
Again JMHO, and I'm Sure Petrik will do what's Best.....either way! smile

Thanks Petrik, that sounds great. Do I need to update from version 2.1.0.62 to accomplish this? Maybe I'm blind I just don't see the option anywhere. I don't generally update to the latest every time you release another version since what I have is proven.

I understand ToxSick's point.  Making the safe condition the default with a checkbox to bypass would be one way to be safe which is what I already have it seems.  The other uses of ABC modes is very interesting I agree.

 for i=5000 to 12,500
to
 for i=5000 to 12,900
