Ferrites on throttle pot leads

[darreni]

Had a spare ferrite kicking about & thought i'd try it on the N/S throttle pot lead to see it stops the flickering.
The cerb seems to drive a bit more smoothly, though not connected it to the computer to see if it really has stopped the flickering on that particular pot.
Anyone else tried it?

Nope, but often thought the next time I have the inlets off I'd try to do something like this. My throttle pot tracings look very shaky. I assume its where the wires had been routed. I played with the idea of changing the wires.

Thought I was the only one being that anal.

Don't most people try and lose weight from a car, rather than sticking lumps of iron on

Errrrrrr....... you know how it is, you've got to fettle here & there, thats what i love about the cerb, and given the way they leave the factory, there's always room for improvement.

keep us all informed

My N/S throttle pot reading jumps around a bit too, I would be interested to know what the laptop says. Excuse my ignorance, I know that ferrite is a type of metal, but what exactly are we talking about here?

I assume ferrite toroids -- little circles of metal split into two halves that you clamp round cables. If you look at your monitor lead, you'll probably find you've got one (albeit a moulded one).

Whack a nice low pass filter on the primary input to the ECU.

Did the trick for me. No more D throttles on idle / part throttle.

Just a shame I sold the car

I wonder how much of this is down to the mbe unit too .. on the emerald if you watch the throttle pot readings they're rock steady .. but on the mbe you always get some flickering of the value on the n/s ..

Joolz,

It was interesting to see that the throttle input on channel 2 on the MBE ECU was much more damped than channel 1.


Hope you are keeping well.
