wizard of NOS and VEMS

[mr_g]

Did anybody use this combination?

Wizard of NOS have ability to pulsate NOS actuators (PWM on 50Hz) to deliver power in percentage...
So VEMS would have to retard ignition as PWM reaches 100%... Also to cutoff PWM when rpm reaches limiter... And limit PWM below like 3.5krpm...

Is this possible? Did those software guy implement it already?

And what about more komplex functions, like VSS (vehicle speed sensor), and limiting PWM when speed is below somethnig, etc...

Theres a multiple map function being developed at this very moment that will provide a different MAP to handle N2O fuelling and ignition, I've not seen it yet so I dont know its function.

VSS is out of scope for our unit because the two VR sensors are occupied with triggering algorithms.

OK. VSS is a must for real idle system... Maybe not so accurate, but is car moving or not... Why do I say this? Because all cars have the system that rises idle rpm when the car is moving by 400rpm, and when it stops, it lower it to origin idle rpm...

Why is this important? Because of possibility that the engine would stall if you press the clutch on lets say 100km/h and rpm falls (forced induction of air in car movement)..

Also VSS is important to launch control, that would automatically turn on and turn off... Well, if the 2 triggering algorithms are problem, we could do this by simple daughter board that have another small AVR (like piggyback) that would inform VEMS of current vehicle speed over serial port or SPI, or something...

What do you think? This daughter board could also act as board computer, measure trip times, average consumption, current consumption, measure acceleration times, etc... I could do this daughter board myself... ;)

BTW, I did NOS controller myself based on AT89C51AC2... ;)

Awesome!

[mr_g]

So, I'd like to get in touch with those developer guys... :D

Use your wiki page.

You could use a clutch switch and neutral position switch instead of a VSS sensor.  OK, so it won't tell you how fast you are going, but it will tell you about movements caused by the engine.

I'm useing it now. But it's a shitty alternative...  ::)
