Re: HotCat's Citroen ZX TU5JP/K engine is running (18th)

This is cool as hell. Is this the first diy hardware that could pass for a commercial product?


Edit: and your desk lamp is pretty cool too.

Re: Idle Control Algorithms - Brainstorming

I concur. :)

Edit: the 2 value deal was more about a minimum workable solution. A 2d curve would be a much cleaner and transparent solution

Re: Idle Control Algorithms - Brainstorming

Phone post again. Re:dashpots. Again I was unclear. If you're familiar with carbed cars they hold the throttle open to physically damp throttle closing Re:deltaT (Torque) jerkiness. Pretty much, except the positive torque at tip-in is constant and there's too much negative torque with the idle valve...

Personally, I think the terminology fits since the main purpose is t hold the rpms high when returning to idle to prevent stalls, but i can see the lack of clarity is an issue. I'll cleanup my post tonight (3-6hrs) when I can get on something with a re...

Re: Idle Control Algorithms - Brainstorming

Here's what I'd want: (X is any user settable value) PID activated on TPS <= X.damn_near_zero Check if engine braking or returning to idle. Not sure on this implementation (RPMdot and Map?). Can use i/o on clutch switch and neutral switch, but I'd make it optional. If engine braking, set idle valve ...
