Just try the Power Valve adjustment. 30% first, then 35%.
Note what happens with both settings, in regards to the two biggest issues.
1). Hunting when cold
2). Lack of overall power, and acceleration
30 may be better, 35 may be over the top. Or it may be better than 30 overall. Or it may be totally the wrong direction. Let's see what happens.
That will tell us a lot about the next step.
Hi. I got home from Chicago at like 1am yesterday, so after work I had a few minutes to fiddle around.
Adjusting to either 30 or 35 did nothing noticeable in regard to cold start hunting.
I didn't have the opportunity to let it warm up and drive it yet.
Glad the trip went well.
OK perfect, that is exactly what I was hoping. It means there aren't any major issues we need to worry about.
When you welded up the shaft on the exhaust valve, did you remove the blade?
When you get a chance, run a grade and see what happens with power. You can just do this once at 35% if you don't have the time to mess around.
It's either going to be a noticeable difference or not. We aren't looking for maximum power yet. We just want to know does it make a difference that you can tell. So don't think this one step is going to fix everything. But we need good input to know where to go from here.
Also, if you want to mess around with the adjustments to see what does what, by all means, go ahead. If you get really off whack, just hit the reset.
Take a note pad with you, and write down what difference each change makes.
There is nothing "magic" about this, and you'll learn a lot from the experience.
I usually tune on the road, and then make a tweak here or there over the next few weeks if needed.
