WANTED: ...... PW2 *expertise*

[Frank Adams]

This may be a question for Mike Belcher(Dyno-Jet)...but help if you can?

I've downloaded the full tutorial from the Power Commander site.

Now, knowing a little more about how to use it and apply Maps....

How would one decide what formulas to enter in any given box(section) on the four tables?

I know this could probably be answer in many ways.....but from the guy's that made thier own Maps; how did you know did you know what to add or subtract from where you did?

Is there another Tutorial on thier web site that explains in more detail what I'm asking; or do I need to run to the airport and take one of Mike Belchers classes?

Any Clues?

Little late. Sorry. I only found this site a couple of days ago. My map making experience has only been a few weeks old, but it's great fun. The map I'm on at the moment was arrived at in three stages. 1) of all the bog std. maps off the PC sites, Richard at TTS did the hard work of finding out which one was the closest match just playing with each map on a dyno. 2) Having arrived at the closest match, we then spent a morning evening out the rough spots on the curve, just tweaking things and running the beast on the dyno. I have to say Richard was doing all the work here too. 3) Armed with a laptop computer and the PC software, I've been fine tuning the bottom end to the point where I feel comfortable, just by riding around and looking carfully at revs, gears and throttle position when I get a feeling that somethings not quite ok. With me it's just been plain old experimentation. What I know about engine tuning, you could write on the back of a small book of matches. I very quickly got used to what too rich or too lean felt like though.

The map you pick is generally dependent on the pipe you are running. Each map has a note attached it to describe what pipe it was made for.

In your case there isn't likely to be a map that even comes close. Dyno the bike using the zero map. Then start adding fuel, run it up, is it better add more, if worse go back. Keep meticulous notes of everything you tried. Change as few values as you can at one time. Good Luck.

Yes there is an extensive tutorial at their website. Look on thee CD that came with your PC2. The tutorial might be there too.

Good Luck.

Ok....I downloaded the tutorial from the pw web site, and as of now, I left my software at my engine builders.(stupid Me!)

When you say to add fuel, how do you know where to add it?

Example:
10% 20% 30% 40% 50% 60% 70% 80% 90% 100%
1000
2000
3000 +15 +11 +3 -2 0
4000 +9 +7 0 +1 3
5000
6000
7000
8000
9000
10,000

On this Map it shows at 4000rpm's at 50% thottle is....+1

My question is...
1st. how do you know that is were you want to raise or lower the formula?

2nd. where do you get the amount from that your going raise or lower it; how do you know to lets say go +5 or +25?

I've got the idea down how to change the numbers on the graph, I'd just like to know how you decide by looking at your Dyno sheets that you want to go a place to anywhere and say....ok, go to 5,000rmp and 40% thottle and richen it up?

Sorry for the confussion!

Its funny frank, I am still very intimidated by the software as well but I can tell you this. You need access to a dynojet 250, anything else aint gonna achieve the perfection you need when developing maps for highly modded bikes. We have 2 in the state of fla and both are dynojet certified tuning centers. Both are 3 hours away from me. When I do my cams etc. I will be taking the bike up there to perfect a map with the mods installed. Is there a 250 nearby? Also Bob (ramair1@flashnet.com) is very familiar with the software and altering fuel delivery.

 

[Frank Adams]

I'll bet he is, but he never seems to jump in and lend a hand anymore?

I must have pee oed him sometime ago?(got me)

Anyway, the closest one to Me is just 4 hrs away.(like everything else)

My engine builder doesn't have the know how with the pw2's, so I guess I'll be headed that way sometime soon?

Doesn't it suc knowing that your stuff is not quite right yet??

Turbo1300 said he'll also be heading to the 250 soon.(Big 1390)(oh yea!)

 

[Guest]

Now I dont feel so bad about the 3 hour trek, like you said its the only way.

 

[Frank Adams]

Hmmm....I guess theres no luck on this one?

Back to the drawing board.....

 

[OB_Dirty Pete]

So Omega who ever felt bad about spending 3 hours on their Hayabusa...6 hours return...especially when the destination is an excellent dyno session?

Things could be a lot, lot worse. Especially now that the heretofore taken-for-granted 1/4 mile invincibility of the ZX12R appears to be crumbling like overheated titanium?

Am I gloating a little? Naaaaaaaaaa...

 

[Guest]

You think thats bad, wait till the handling issues come to light........

I have little bit more info for what its worth. The PC 2 varys the output of three sensors to increase or decrease the fueling/ignition all are linked to RPM.These are:
1.Throttle position sensor(fine fueling adjustments)
2.The external air pressure sensor(coarse fueling adjustments)
3.The crank position sensor(ignition timing)
The ignition timing is in degrees.The fueling is related to the sensor on the bike.So the number 5 may not mean 5% more fuel just more.
