Petrik, quick question, do we need to turn "Pair" On or Off for the DSM to activate the N2O.....or does it even matter? Thanks

Yes, you need still to do that manually - until its fixed to automatic.

Do you mean Turn it "off" Manually? Little confused by your answer....Sorry.

Thanks Petrik!

1st Harness is built....

Funny, with No LED hooked up in neutral and 1st gear the relay cycles at WOT with DSM button held, but lightly, and not enough to allow even an air solenoid (much smaller current to open than NOS solenoid). 

Just like gen 1 relay goes between ECU and battery, terminal with fuse holder goes to battery +, other terminal goes to battery -


2 pin molex connector just needs 2 pins crimped onto your solenoid, then insert into connector and plug in.


Pair valve just plug into the connector where octopus solenoid was connected.

actually bike is clean as hell, its sweaty as hell, been cold here and today its 45 degrees LOL

yes its leaking some, petrik is seeing same thing, yesterday with a relay and LED hooked to the circuit the led would blink dimly in 1st gear but relay wouldn't click

now relay clicks softly but doesn't actually activate the air solenoid i have connected to it

Here is the harness off the bike.

The first 2 are setup for solenoid under the tank per Stocker and Toxxic's plans, but my generic one once tested to work etc will probably go to hump unless customer specifies differently.

very nice work Petrik unbeailivable!!!

i have a question for us who use the quick shifter module do we have to use only ign cut or there is no problem with ign and fuel cut together?

well ok but imagine what is going to happen when only nitrous goes into the chamber with no fuel.

if u tested Greg then it shouldn't be any problem with that but if there is a problem then we must cut nos too when upshifting

The problem is actually the opposite, If you only cut teh ignition and leave the fuel, both fuel and nitrous will enter the cylinder, and then the exhaust. This sometimes results in a loud exhaust backfire. Cutting the fuel prevents this for the most part.

Looks Great Greg!  Thanks for Jumping all over this Project for us......Says ALOT, when your not really even a N2O Guy! 

 

i like it, just hate filling bottles, on my wifes bike with 2 lb bottle i only wanted to ride about 20 minutes, then bottle was empty and bike wasn't fun anymore LOL

no problem guys, excited to see if this works out perfect first time out for you guys.  You guys have access to dyno and wideband?

I have a Wide Band(Wego3), and I'm going to call my Dyno Guy tomorrow and see if his Dyno is Still Down??? If not I will throw it on there As Well.

Petrik , If you are running high fuel values already (Oxygenated fuel) and you are having a substantial hit of No2 The fuel value will exeed 300. Is this an issue or must one just check duty cycle of Injectors while spraying or fit bigger secondaries ?

Thanx for help Petrik , Pair boost control will be great .
Pure Genius the duty cycle bar.

petrik, i was editing the nitrous control module today, i was not able to edit the individual cells, rather i had to use cntrl + or - and it edited it that way in a % point of view, is this why you wanted % changes for the jet changes...?

Yes, editing is limited to +,-,*,/ last two working only when div/mul with 1.05 (i.e. 5%) is more than an integer.

Fuel row on the nitrous control module is more or less absolute % to fuel pulsewidth, but I have not tested this with gen2 in dyno myself yet so that is one item to be confirmed with testing. With gen1 when adding 10% to fuel you were good for 32-34 jet size etc.

Today received the following info on duty cycles (Thanks tor greg/ryan):
75-100% duty -> 100% flow
50% duty -> 75% flow
40% duty -> 50% flow
etc...
20% or less duty -> 0% flow

The duty cycle is another item to be confirmed over testing. We will get a picture of it when we have a couple of bikes tuned for differen duty%/fuel% settings. The rest we can calculate from jet/bottle pressures.

When we have this kind of basics right we can start to add gear ramping rates and injector delay times etc where the duty cycles are not anymore fixed.

EDIT - The max duty cycle if I remember correctly from scoping the fuel signal earlier was somewhere around 460-500 which is around 85-100% fuel add. This depends on pressure etc. Obviously the fuel pump needs to be already at values around 300 or the flow is not anymore constant. (This is an assumption knowing the pump volume, not exact tested number).

I will add at some point this kind of fuel pulsewidth information to the engine data monitoring screen in a more graphical and informative way than what it is today.

 thanks for joining us nick...maybe we can get ALOT of insight from your expertise with nitrous....AND with busa motors in general......MAYBE we can utilize your spray bar as a common spraybar in which we can test from........

Ok Bro.... Enough patten ya on the back....Now get to work(lol). Start at page 1, and start reading......Let us know whatcha think?

gixx has the ability to "accurately" measure the flow rate on his spray bars....if you have any questions.....he is now a registered member here...or i can provide his pm adresson "both" of the other premier busa sites......
