when the bike starts cold the module does not bring the rpm up as i read it should.
When cold, there is no evidence of the ETC mod being installed. Once up to running temperature, the increase in idle speed is noticed. The ETC mod effectively tricks the bike into thinking it's always colder than it really is when it is dialed up.
I chose to modify and looking back I think I would seek out a LINEAR 10K pot and not an AUDIO taper type. The Audio type will increase resistance logarithmically. Mine was of poor quality at radio shack. It made it very touchy.
I removed the resistor and tied both "wings" together. This will give me 0 Ohms at the ends and 2.5k in the middle. I measured with a meter and set my knob indicator for CENTER at this highest resistance. I'm going to go take a test ride now, so I'll let you know how she does!
The setup on the Shop Talk page, using a 3.9k across one "wing" and the center gives you an increasing value from 0 to 2.8k. I don't have a linear 10k pot here or I would try that as well.
The nice thing about the adjustable, is that when you are "trapped" in traffic you can dial it down and lower the rpm without having to shift to neutral. I decided against the clutch mod for two reasons.
1) More splices and wiring / diode ( i have many diodes - but a failed diode would be confusing to troubleshoot if not familiar with the circuit )
2) The I don't mind the increase. If I'm at a long light, i pop it in neutral. If I'm in traffic, I dial it down.
The mod shines because it doesn't effect high end performance. ( above 3.5k RPM ) That means you get the grunt when pulling around corners and jacking up hills. I live in TN and love the performance! A friend that normally rides a Eltra-Glide got stuck and because he wanted to ride so badly here, he rode the Valk, while i rode the FJR. He was completely blown away that he didn't have to shift going around the corners and up and down the hills. Now any Valk - mod'ed or not will do that in comparison to most any V-twin, but I likes to think the extra low-end kick got his attention!
