Happy Knob
 

Just wondering what rheostat to use and the best one to buy.
thanks

Failsafe thermo, 180 degrees.

no, we are talking potentiometers here

DIY? You know it'll only get you 2-3 degrees of timing (6hp at MOST), and probably isn't worth your time? I'm the only one I know of on this Forum to do a DIY happy knob, and that's exactly what I gained.

Frankly, if you don't know what pot or rheo to get, you don't have a manual, haven't done your homework, and probably shouldn't be doing it.

Mine is wired back to my PCM and is selectable.

actually im an electritian for the largest non-union shops in the midwest, so i think i can handle reading a schematic and would appriciate not being talked down to, i am 100% capable buiding it, i just wanted some pointers on were to get started

The factory service manual is where you should start. I'm hesitant to help you with it considering the negative reaction you've had to our well-advised changes to the setup you have in your car.

I simply used the FSM to determine where to wire in my Estat, Happy knob, and fan override. That's posted in a topic already.

I'm not about to help you advance your timing on that setup, simply because it would make me partially responsible for you blowing your motor. Even 2-3 degrees of timing with your setup could spell disaster, and we've had people pop pistons with less extreme goofs.

ya because i was going to crank my timing up 10 degrees, not scan it and step on it
thanks for the pointers :knob:

Hey, Knob. Look in the mirror. Is there some written rule that says I have to help you blow your motor up? Nope.

Another clue........I don't like being called a knob.

Attitude will get you nowhere here. And he's had a history of it since he walked in the door.

Anyway, for the S1, the happy knob isn't really worth it for the work, considering the little gain you can achieve. I did it to prove it. Since I have it, I use it, but I honestly can BARELY feel the gain if I'm under load in overdrive with the cruise on (climbing a slight grade) and turn the knob back and forth.

I get more use out of the estat part of the happy box. Cold starts with the 160 thermostat are far too rich for far too long. The estat tricks the PCM into thinking it's warmer by 20 degrees or so, cutting the time that I'm in fuel enrichment mode.

6hp is still 6hp right?

Not when you're running the wrong PCM with the wrong engine and the wrong injectors, and have no scantool.

What exactly is a "happy knob"? This is the first I've heard of one on this forum.

yeah im hella confused

do a search fellas

true but i think we have all the resources on this forum to provide to somebody in making a strong car
so will its up to him and anybody on this forum to take into consideration what BC has to offer if not then let them blow there motor right? thats my views so if he wants to know tell him all you can say is i told you so in the end

For someone that types in all lower case and with no punctuation its hard to believe your an electrician.. :roll: :roll: :roll:

Considering the number of people that have butchered car parts and not followed my advice in the past, due to trying to copy things I do, I think I'm in a position to be the judge on that one. Particularly when the modification requires tapping directly into the PCM wiring harness.

Besides, it won't work for your car. If you read the topic linked, you'll know that. You have a MAP sensor tied to the PCM. My MAP sensor is not. It only provides a boost indication.

i could careless if it would work for my car but your somewhat right in away
the experienced and knowledgable stick together and all the rest gander in the distance

Have you ever noticed how many people here try to tackle a complicated problem or project without a FSM? That's part of the problem here. Nobody should even CONSIDER this mod without already owning a FSM. If you have it, and don't understand how to do the happy knob, it's an indication that you shouldn't.

For those that understand, it's safe to say they have the skills to pursue it. This is one of those unique things that you shouldn't attempt unless you PERSONALLY fully understand it, how it works, why it works, and how to do it, not to mention already owning a scantool and FSM.

indeed FSM Is very helpful i still need a set for the 99 if i keep it
you need the right tools then knowledge
ok back on topic
