Its a shame that the alky controllers out there are so expensive.

I got a standard PWM controller capable of 25amps for freakin pennies. I used a TPS switch to activate the system and I'm thinking about adding a 0-22psi map sensor (~$5 from digikey) to give it some progressive control.


I've also got a simple darlington switch i plan on using it to control a nitrous soleniod that will get a signal from the stock injector driver..

That way the whole system is progressive with boost, has controllable pressure, and is linear with the stock fuel system.

I'm not even familiar with what a PWM controller is LOL!! want to enlighten me?

Instead of cutting voltage to the pump it runs it in a duty cycle way..

You get alot better control.

Well now you've got us interested so spill the beans, HOW did you build it, where did you get the parts, etc......

I told you what it is, Just do a search for a schematic for a PWM controller.. anything about 20 amps is fine.
