6 stage nitrious controller

The Maximiser progressive nitrous controller provides a digital pulse width modulated output to pulse the solenoids to control the flow and hence the power, of a nitrous oxide injection system. It offers direct replacement for any other control system on sale but with the following enhanced features: Simpler to use (on screen operating instructions/guide), More user friendly, Ready to run without the need for initial setting up (Pre-programmed initial set-up), Improved accuracy of timing and power settings, and provision for additional features to be added to the current unit by a simple chip change.

Menu 1

Initial Delay:
The time the nitrous system can be delayed from activating after the throttle switch is operated can be adjusted between 0.1 and 9.9 seconds.

Build Time:
The time it takes the nitrous power to build up from the “start†percentage to the final power, can be adjusted between 0.1 to 9.9 seconds.

Start Power:
The percentage of full power that is delivered when the system is first activated is adjustable from 15% to 100%.

Final Power:
The percentage of full power that is delivered at the end of the build time is adjustable from 100% to 15%.

Run Timer:
The run time that the nitrous system is activated for, can be adjusted to restrict the system operation to a desired length of time after the initial activation. The range of adjustment for this feature is 4 to 20 seconds.

Burn - Out:**
1) The Burn-Out feature provides an adjustable, pre-settable fixed amount of power to be used during a burn-out. It can be set to a number of operations to allow the user to hold the same power level throughout a static burnout and / or a rolling burnout and / or a dummy launch prior to automatically switching to Race Ready. This feature also has a manual override feature by pressing any of the panel buttons.
2) This feature can also be used to prevent system activation for a single or a number of gears by setting the power level to 0% and adjusting the number of operations, so nitrous activation can be avoided in early gears where traction may be a problem.

Reset Options:
The reset feature provides a number of options that can be adjusted so that every time you back off the throttle and go back on it again (e.g. as you go up the gear box), you can pick what power setting or option suits your vehicle best.
1) Build up power level Hold.
2) Reset to the Start power percentage.
3) Reset to a specific percentage power level.**
4) Reset to Start power percentage plus or minus an adjustable percentage.
5) Reset Build time plus or minus an adjustable amount of time.

Nitrous Pressure Offset: **
Activation of a nitrous system (over the period of a run on the drag strip for example) can result in a drop in bottle pressure and this is worse when a relatively small bottle is used with a relatively large jet. This drop in pressure can become a problem and cause the NF ratio to become too rich, resulting in a serious drop in power. This feature allows the Maximiser to take away a percentage of fuel over a set period of time after a chosen delay, so the correct NF ratio can be maintained during the whole run.

Frequency Adjustment:
Different makes of solenoids pulse better at different frequencies. To allow the Maximiser to be used with all makes of solenoids the frequency can be adjusted to the best frequency for optimum results. The range of adjustment for this feature is 8 to 50hz.

Nitrous Delay:
The activation time of the nitrous solenoid can be delayed relative to the fuel, to eliminate the initial lean-out that systems with pipe lengths longer than 3†will suffer from (to some degree – the longer the pipes the worse the problem). The range of adjustment for this feature is 0.01 to 1 second.

Fuel Delay: **
The activation time of the fuel solenoid can be delayed relative to the nitrous, to eliminate initial rich running, which some systems can suffer from if the nitrous and fuel solenoids / injectors are mounted in different locations (eg. on some bikes the nitrous injector may be mounted at the front of the airbox and the fuel injectors fitted in the inlet ports). The range of adjustment for this feature is 0.01 to 1 second.

Ignition Retard Output:
This is an adjustable switched output that can be set to activate at any percentage power level and needs to be connected to an aftermarket ignition system with an externally switched retard feature. The range of adjustment for this feature is 20 and 100%.

Max N2O Flow:
Fuel solenoids will work over a wider range of percentage power than nitrous solenoids will, because they work at much lower pressures than nitrous solenoids have to do. For example a fuel solenoid (working at 30 psi) may pulse from as low as 10% and up to as high as 95% but the nitrous solenoid (working at 950 psi) may only pulse over a narrower range of 30% to 60% (for a bad design). This means that when the nitrous has stopped pulsing at 61% and stays full on the fuel solenoid is still pulsing all the way up to 95%. This can result in a very lean mixture and terminal engine failure. This feature allows the operator to match the fuel solenoid full on percentage to that of the nitrous solenoid.

Nitrous Contents Indicator:****
The nitrous contents indicator can be adjusted to your systems jet size and nitrous bottle capacity. Once reset it will display the contents in seconds on the ready screen. As your nitrous contents diminish the time will reduce to represent this. The contents indicator uses quite a complex flow table to calculate the remaining ‘nitrous’ time available and even takes into account ‘progressive power.

Saved Settings:
This is a data store in which the operator can store up to 10 sets of parameters (programs) which they may want to use at another time after making some adjustments, without having to make notes of each individual setting and reload individually when required. With this unique feature you can save all the settings that have been chosen, in an individual numbered log for reloading at a later date, all at the touch of a couple of buttons.

Test Features: The Maximiser can be run in ‘Test mode’ to carry out tests on the unit and the system for basic testing or fault finding. Test features include the ability to individual test the solenoids / outputs, the retard output, test the throttle input and even carry out the ‘static test’ all at a simple touch of a button.

Your Maximiser unit can easily be upgraded to Race and/or bottle contents indicator by simply entering a code on the relevant screen. No need to remove it and send it back to us!

General Features:
• Pre-programmed ready to useCool Blue backlit LCD screen Power Bar display (shows fuel and nitrous percentage delivery rate).
• Touch panel button adjustment rather than breakable knobs.
• Rugged extruded alloy case (anodised black).
• Laser cut and polished stainless steel mounting brackets.
• Integral wiring loom, no plugs for greater reliability.
• Shower proof.

Electrical Specifications:

• Operating voltage: 8 – 24 V DC.
• Max current draw (without solenoids): 0.2 amps.
• Max current outputs: Fuel – 60 amps (for up to 10 seconds continuous), Nitrous – 60 amps (For up to 10 seconds continuous). In English this means up to 4 sets of std pulsoids can be run from one Maximiser, 3 sets of large solenoids of other brands and up to 8 sets of the smaller solenoids of other brands.
• A remote power Mosfet pack can also be supplied to run systems which will draw more than the maximum current.
• Retard circuit – 10 amps (for up to 10 seconds continuous)

1) When using any solenoids other than our Pulsoids it is likely that a 2nd solenoid will be required as a safety back-up unit. Pulsoids are the only solenoids that will not wear, suffer from seat seal damage or seize open due to pulsing.
2) Solenoids other than Pulsoids will not pulse accurately over the full percentage range of the Maximisers output and may only have an effective range of 40-70%. Pulsoids have an effective range of 10-95% depending on how the seat lift is adjusted.
3) Ordinary fuel solenoids (as supplied by all other nitrous companies) will respond at a different rate to the nitrous solenoid, which can cause engine damage. The Maximiser has features to minimise the above problems but to get the best results from your Maximiser it is advisable to replace your stock solenoids with our Pulsoids for improved vehicle performance.
