Re:Are you guys interested in cheap AFCs?
Blundar you are the man, thanks.
BTW what do u think about me using an injector to control boost? Hey i still have timing questions, I posted them up at PGMFI.org in the general section. Any help is greatly appreciated. Regards, Alan To |
Re:Are you guys interested in cheap AFCs?
much simpler: use a simple bleed solenoid. I raped a couple from my emissions box. Who needs that garbage anyways?
Turbo =====T=====Wastegate | bleeder | don't know if my ASCII art will work, but hopefully you get the idea. Use a normally-closed electronic valve. (AC, emissions, etc.) and T-it into the line between pressure and wastegate. When you want to raise boost, open the solenoid. In order to avoid overboosting, you're going to have to do some kind of velocity calculations ... figure out the rate at which boost is rising, and start feeding the solenoid a PWM signal with a duty cycle from some kind of lookup table trying to decrease the velocity of boost increase and get it to stabilize at the target without overshooting it significantly. After you hit the target, a closed-loop-like feedback system could regulate the PWM duty cycle and oscilate between slightly above and slightly below the target. |

Some thing that could act as an AFC and read/convert/display a wideband O2 would sell very easily for $150...
The timing retard thing would just put it over the top !!! |
Re:Are you guys interested in cheap AFCs?
yeah, patent it before you sell it. that would make a killing.
ill buy one. |
Re:Are you guys interested in cheap AFCs?
i would buy one to ;D
|
Re:Are you guys interested in cheap AFCs?
dude u r the man! i wish i could do all that computer ----. and i would definately buy one too.

Re:Are you guys interested in cheap AFCs?
keeping it to the top
and you keep us updated. |
Re:Are you guys interested in cheap AFCs?
Sounds pretty cool Alan. Good luck. :)

Re:Are you guys interested in cheap AFCs?
I'm going to be doing the same thing in the future. Its good to have competition. I also will be using a PIC microconroller.
