Hi Jamie,

As I eagerly anticipate the arrival of the PowerVision, I'm trying to get myself ready for what I am getting myself into.

Therefore, I have a few questions I hope you can answer to help me (and hopefully others) on our way.

I know nothing about tuning.
Is the bike running lean, rich? how do I know? What do I do about it?
Timing? Front and back? etc...

Could you please point us in the right direction?
I would like to know what it is I'm looking at, what it is I'm trying to do, and how to do it.

Thanks in advance,

Lou

This is a very broad question. As for getting started I would first browse the forum and read up on the EFI and tuning threads. There are also some very good books and DVD's on tuning fundamentals, while they are generally geared towards automotive tuning the same principals generally apply. The books by Greg Banish are very good. We will be posting the Power Vision user manual as soon as it is available in PDF format.

Thanks,

I've been reading the other threads on the subject, but there doesn't seem to be a tuning 101 thread, where general questions are answered.

When someone says they are running rich or lean, I would like to know how they know that? Can you tell just by riding, or it becomes obvious once you pull the data? there are the kind of things i would love to know.

Anyway, I hope the user manual helps a little

There are a number of ways to tell. Inspecting your spark plugs is one, if they are black, you're running rich. White, to lean. Good running should be in the brownish greyish area. On a dyno we proble your exhaust with an air fuel sniffer. It tells us what the bike is doing, we proble front and rear cylinders independantly. The new PC vision that will soon be available from FuelMoto will be able to give you real time a/F reading for each cylinder as you are running down the road. Should be a real benefit to thoses that want to self tune. It should take alot of the guess work out of it. Proper tuning isn't something that you are going to get figured out overnight. Dyno tuners have 10's of thousands of dollars in equipment to achieve proper tunes. I would suggest you start with as close a MAP to your build as possible, then maybe try tweaking it a little first off.

You won't do it any harm. just unhook the PC and take it to them. Tell them you want the stock calibration put back on it. Whn they are done hook the PC back up and you should be fine.

Thanks for the info.
Since my question was too broad, I'll ask it a different way...I think this should help.

My bike is currently undergoing some engine mods. Because I'm in Switzerland, and don't know any indies, and can't do a lot of the work myself, I am stuck using the dealer and the parts I will mention below. I'm sure that there are better cheaper etc parts, but these are the ones that I'm getting, and it's too late to change that now

Current setup
2011 48 with
Arlnen Ness Big Sucker
Kess Tech Exhaust
SERT
The SERT seems to be doing the job, but then again, I'm no expert

I'm having these parts installed as we type (all SE parts):
Cyl Heads 16677-07
Pistons 22711-04a
push rods 18424-06
Cams (.551) 25197-04

My question is then, starting from the previous map (stage 1) what changes are needed to take advantage of the new set up? By this I mean
"with the new cams and heads you will now be running rich so you need to xyz"

or something along those lines. I'm pretty sure you can't give me exact numbers, but I'm also pretty sure you know where the lines have shifted and what directions they need to be adjusted in, maybe even a rough estimate as to how much.

Thanks again for the help, it's much appreciated.

Lou

By SERT i'm buessing you mean the SEPST. Black or orange box with a button on it? I'm guessing this beacause they don't make the SERT anymore. You're going to need to find a MAP for your build and smarttune it yourself. Noone will be able to tell you what exactly to change. When you are talking changing your VE tables you are talking about changing hundreds of cells of data. Here is a snapshot of the VE tables. Keep in mind this is just for 1 cylinder, (the front). To get your bike running just about every cell on the page will be adjusted, as well as the same thing on the rear cyclinder. So for anybody to tell you which cells and how much to adjust (up or down) woud be imposible. Anybody that would even try would be full of it. If you don't have any tuning centers over there, you're going to have to learn to Smartune or get a new fuel management system that autotunes.

Gulp

ok, i see what you mean, but I thought you would know from personal experience the effect that changing the cams would have on the bike, ie because the engine is now taking more gas in, it'll be running rich, so you need to start by doing ?????

Jamie did say that the autotune will work on the powervision, but that it's experimental right now, and also, there is a dynojet autorised tuner in zurich (about 3 hrs drive from here) so as long as the map the dealer loads works fine, I might have to pay them a visit.

Thanks for the info, it's greatly appreciated.

Lou
