TC88A-EX Maps

[84XRrider]

I am trying to learn a bit and have picked a few things up from the threads, so I had gone ahead and altered a couple of the popular posted maps to load to the EX, one carrying the 16 values down and one with some best guess values based on the factory trends, but H-D was kind enough to send me maps to try so I will test those out. I'll also pull some log data too and reply back with how it goes.

Why use a vacuum gauge, the TC88A can store the last 30 minutes data ????
The map pressure will show on a graphic.

Because that will let you see in real time what manifold pressure (or vacuum) you have in different situations. You then know what's cruise and at what point you transition to wanting to make power and what is deceleration.

Marking your throttle grip and housing so you have a (relative) idea of how much throttle you're using is helpful too. As you optimize your timing and fueling you'll run along using less throttle. It's a way of gauging progress.

Yep I was thinking the same thing, about temporarily putting a small gauge on the bike so I could know the what the vacuum is at the time I had an issue.

Bigger gauges, 5" or 6" in diameter are a helluva lot easier to read. It's temporary. The biggest issue is getting the gauge damped well enough.

I want to check in to say how nice the 1200 runs with the maps from
Highly-Dangerous - thanks again for sharing them.

Thanks for the feedback. Enjoy!
