Actually, it is probably better to discuss here, for future reference that someone else may use.

By "programmable output" I was using MCU speak. Using MS speak, it would be called "spare port settings".

Look for "spare port settings" in the MegaManual URL I provided above. It shows how to use some ...

The bike idles around 2kRPM. With the lightened flywheel and 13.5:1 compression, it is pretty rough below that. The 1300 number is to get it started. The starter is not strong enough to keep the RPM stable, and the startup is also pretty variable.

I am running the V3 board, and it is theoretically ...

I have a 2001 KTM 520 (540) in my racebike running on MSII, which is pretty close to MicroS for this purpose.

This bike only has one reluctor on the rotor, pretty wide, about 30deg.

After watching the vacuum traces on the oscilliscope, I did not bother with trying speed-density and went straight ...

...
I also tuned the VE tables with a wide band O2 sensor. I also had heard that a wide band sensor would not work in a 2 stroke. But it does. At least it's lasted long enough to tune it. I'll report when/if it dies.

This bike is running. I mean, like it was fuel injected from the factory! It's ...

The versatility is there, no doubt! Thanks for not sticking with "ass-umptions" like so many systems do.

I was just wondering if my thought process is correct (or close) on how to use it, since A-N is not discussed much.

I take it that pw calculated from the VE table should be reduced by 7.52% since at higher altitudes less fuel is to be supplied?

Philip,

No. The MAP sensor output compensates for the lowered intake pressure (unless you are running alpha-N...).

The baro correction compensates for the lowered ...

Been racing it for 3-4 years now.

Stock was 63hp
All work done with 41mm FCR carbs was 82hp
Replacing FCRs with 46mm TBs and MSI gives 94hp

It goes like stink, too bad the rider stinks too.

Sorry, too many valves...

It is a Suzuki SV650.

mrbell:

Have you been out of the loop with motorcycles for a while?

Many built in the last 5-10 years have quite a bit of alternator output, I don't think anybody builds with Lucas components anymore.

Many motorcycles don't even have petcocks anymore, or they are very difficult to get to and ...

Saw this when you were kind enough to post the URL before.

Unfortunately it will not fit down a deeply recessed spark plug hole. Not a problem on a 125/250, but most modern 4T bikes have tall heads and very deep plugs.
