Large gain Nitrous oxide systems without a progressive controller can cause considerable stress on the engine and drivetrain of your vehicle and valuable power can be lost due to excessive wheelspin. Progressive systems are used to build up power gradually and are preset by the user, this unit allows you to adjust your system to suit different road/track and weather conditions and also gives the the control needed to increase your bhp gain. Pulsing led's inside the unit will flash in sync with your solenoids giving a visual indication of the units output. The unit is modular and has a fitted plug to allow removal and prevent theft, also handy if you run more than one vehicle with a system fitted.This unit is the latest and safest most advanced digital controller on the market.
When fitted correctly nitrous oxide can give excellent power for money but in the event of a drop in fuel pressure or similar engine fault can and will destroy your engine. This unit has been designed with excellent engine protection facilities included as standard ,utilising the sensors fitted to most modern vehicles this unit can be programmed to kill the nitrous supply in the event of a low reading on either fuel pressure, oil pressure or fuel /air ratio. Will monitor fuel mix and vehicle battery condition as well as giving the ultimate in power control, and as we make them ourselves we offer a 24hr replacement service in the event of component failure.

Parameters and Uses of each Function
- DELAY - provides up to 5 seconds of initial delay from first WOT, this can be used to prevent wheelspin when first moving off, or to allow the revs to build up before the nitrous is injected into the engine.
- NITROUS DELAY LINE - this is a delay in turning on the nitrous solenoid to compensate for the fact that the nitrous moves along the pipes faster than the fuel as its pressure is greater than the fuel. If the solenoid to injector lines are long this effect is more noticable, or if the power level is set very high. In many cases this is not needed, it is always safer to overfuel the engine rather than running lean, even for a very short time
- START POWER - sets the level at which the percentage of nitrous injected will start at, the lower the RPM the system is activated at, the lower this figure should be. Also the wider the start/end range is the better the progressive flow will be, if you find you need to set the start at very high levels it could be worth considering an increase in jet size.
- END POWER - this sets the final power in the progressive curve. In a well sorted system this should be at or very near 100%. The adjustability is mainly to allow for reducing the power in unfavourable conditions, like wet or poor road surfaces. When selecting this function the lowest power will automatically be changed to ensur eit is not lower than the start power- even if you have previously set it lower.
- BUILD TIME - this sets the time taken for the progressive curve to go from start to end power settings. This should be set to coincide with the engine accelerating from the starting RPM to just below maximum revs. If the engine can handle the power its OK to reach the end power before maximum revs, but to set it longer will just loose potential performance. There is a minimum time allowed of 1.5 seconds, this is the minimum time that thefull progressive output can be achieved in. Setting lower times will cause the unit to become innefective on a street car and therefore is not advised. For high level racing applications this limit can be overridden- pleas consult our technical dept.
- FREQUENCY - this is to match the different solenoids to the unit for optimum performance. The bigger the solenoid and heavier the internal plunger, the slower the frequency needs to be. For small solenoids(up to 150BHP) set to high, for 200-250BHP ones-set to med, for over 250BHP set to low. This is just a starting guide, trial and error will determine the correct setting. If this is too low, the power delivery may seem jerky or pulsing, if too high the power delivery may seem very sudden with very little progressive action.
- REV LIMITS - before using this function, select test mode, step through to rev test and check reading on the screen against tacho. If it doesnt read anything then an adapter is required- see your dealer or consult our tech dept. If it reads x2 or 1/2, got the no. of cylinders setting menu and change this setting, even if ti appears correct to your engine due to the design of some ignitions "double triggering" or "half triggering" are common occurances. If this does NOT work, be sure to select OFF in the min revs setting, If it does work go back to the function menu and set:-
- MIN REVS- this si the lowest RPM the unit will work atregardless of throttle or other inputs.
- MAX REVS- this is the highest point the unit will work at regardless of any other inputs
- No. OF CYLINDERS - sets ths pulses per RPM counted by the unit, it should, but not necessarily- be set to equal the cylinder count on the engine
- TPS/MICRO - this selects the input trigger type, for most modern fuel injection cars a sensor is fitted to the throttle to indicate its position, tapping into this simplifies the WOT detection, if you have carbs, then the microswitch will need to be fitted so it trips at WOT
WARNING; THE CORRECT SELECTION MUST BE MADE IN THIS MENU, if TPS is selected for micro use, the unit will never turn on. If MICRO is selected for for tps use theunit will activate either continuously or too early and the input fromthe sensor to the ECU on the vehicle will be affected causing erratic running of the engine
- MIXTURE MONITOR - this checks the oxygen level in the exhaust via the vehicles aftermarket Lambda Sensor. If the mixture goes lean either a warning is shown on the screen, or the output is turned off, or just the nitrous is cut- then returned when the oxygen level corrects itself. The latter function will effectively richen the mixture to enable continuous use of the system without engine damage. This is primarily intended for race situations and should not be continuosly relied upon if there is a fault with your nitrous system.
- FUEL PRESSURE - if activated this monitors the fuel pressure and will cause the system to cut if it drops below a safe level
- OIL PRESSURE - if activate d this monitors the oil pressure an d will cause the system to cut if it drops below a safe level
- CALIBRATION-TPS - this function will automaticaly calibrate the unit to match the TPS sensor on the vehicle. It only needs to be done once when first fitted. Ensure the throttle is closed then when prompted press the button, open the throttle to full then press the button again. Confirmation of complete will be shown
- CALIBRATION-02 - this calibrates the lambda sensor, again this should only need setting once. With engine running at normal temperature press button and the 02 level will be logged. Ideally this should be done with an 02 meter connected to check the level is correct to start with, some cars will run very different levels at idle and full revs
- MEMORIES-SAVE - to save a setting that you have entered, select a file number( 1 to 3 ) and press OK
- MEMORIES-LOAD - to retrieve a setting that you have previously saved- or the origional factory setting, select the file number ( 1 to 3 ) and press OK
PLEASE READ – SOLENOIDS
Do not pulse solenoids without gas-the gas flowing through your solenoid will cool the coil, if you pulse with no gas the coil may burn out and damage the driver box for the controller, we have tested these units for use with Twisted Sanity, Nitrous Express, Ny-Trex and Cold Fusion solenoids. If in doubt about the suitability of your solenoids for progressive use please contact your manufacturer, with ANY make or type of nitrous system we recommend the fitting of a purge valve, solenoids have moving parts and are therefore subject to wear-turning off your cylinder at night and purging the gas from the line will guard against the possibility of a leak- Older style solenoids have rubberised seals and are not suitable for pulsing, solenoids should be serviced at manufacturers recommended intervals to check for signs of wear. Most of all Enjoy your new product and wipe the floor with the competition.
