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.

 

what controller r u using, and where did u get it?

 

i made it

 

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.
