Questions: Power Commander 2

So I bought a 99 VFR last year and it has a PC2 installed. The previous owner said he bought it as is as well and as far as he knows there is a 'suitable' map from Power Commander on there. The previous owner didn't give me any instructions or packaging or a cable, just the unit itself.
(1)So how can I 'see' which map is loaded?
(2)Would it be worth some dyno time to get a custom map done?
(3)Should I upgrade to PC3 and get a custom map done?
(4)What do the Low, Mid, High buttons do on the interface of the PC2?
(5)The PC2 appears to be spliced into the loom wiring so I guess I can't unplug it to see what the bike runs like without it?

Thanks,

Rob

 

Ok I'll see if I can pick up an adapter for it, and I guess if I can do that theres no real need to get a PC3.
So how do you actually map it manually? I though it was 'low' 'mid' 'high' rev cut or something, lol.
pics would be good if you can manage that, thanks

 

To get it programmed without a dyno is going to be tough, at a minimum you need at least one other thing to do it right, that being an EGA or exhaust gas analyzer - that is the only true way to tell how the bike is really running at different RPMs and under varying loads - I'm not going to say that it's impossible without one, but, if you happen to get it right, it would be like hitting the lottery every week for the rest of your life..........

 

The PCII offers a few advantages over the PCIII...the tuner can also adjust the timing with the PCII.

I would take the $300 you were considering spending on the PCIII and let a dyno guy tune the PCII.

Let us know how it turns out for you.

Cool, thanks mate I'll go fiddle...

 

Same situation.I recently bought a '00 VFR with a PCII,D&D pipe.No manual or cable.Ran like crap in the mid-range.It started fouling plugs.My laptop has no 9-pin serial port.I finally found a guy at a speed shop that knew what he was talking about.They've got a dyno and do a lot of custom maps.He said he'd tried the usb to serial cable and couldn't get it to work.He just uses an older computer with a serial port.I finally figured out how to remove the PC.Your right it does look spliced in,but it's not,as the above poster showed.Bike runs great now.

 

Here is a link to the Dynojet Tuning Centers in Australia:

You could check to see if one of these tuning centers is close to where you live and give them a call and see if they can't help you out locally.

 

does the power commnder really work? all I have is aftermarket pipes which made a huge difference in performance, now you say the pc2 is actually better than the pc3? if so that sounds great, don't know if I can find a dyno shop to do the mods, is it possible to make adj. on the fly and save the best settings?

 

that 's what I don't understand, alot of people (not vfrers) are shocked that I have aftermarket pipes and no power commander, they act like I don't know what I'm doing without one.

Of course I have limited funds for one. Once I put new pipes it completely changed the performance of the bike, no surge at 6000, just straight cont. torque.

What I want is a way to electronically change the ecm settings because I am trying to run my bike on alcohol fuel with hydrogen boosting. That requires the timing to be changed, and the more adj. available the better, Not only do I want to have fun on a bike but not pay $3/gal and ruin the envronment.

 

You can definitely increase or enrichen the fuel mixture quite alot with a power commander,I think Dynojet also makes a timing module where you could electronicly adjust the timing.One thing,I was under the impression that alcohol is really hard on an engine,is that so? Also I believe an alcohol burning engine produces additional heat,if so you may have to change your cooling system . eddie

 

I am reading a book on alcahol fuels and ICE conversion. According to the book, the compression ratios for alcahol are in the range of 14-19 to 1, as compared to standard 8.5:1 or up to 12:1 for a race engine. HAving a turbo or supercharger is ideal in order to get the internal pressure higher, they said any proof above I think 180 is high engough that it wont corrode the gaskets, otherswise there are many cheap, and safew additives that can prevent this for lower proof fuel.

They say that the original model T ford had duel fuel cpapability, and had a lever to change the timing from gasoline to alcahol, but I do believe that the oil cartels stateside and abroad have spent millions to keep alternative fuels down for their own profit, alcahol fuel was one of the first fuels looked into to power these engines, not gasoline which we know is destructive. I also have a dvd produced by the guy who started the Amercian hydrogen society, he says as little as 5-7% H2 can be used to boost just about any fuel no matter how low qulaity and octane rating that it can run an engine like gas but better, more complete combustion, less hydrocarbon exhaust, and because the timing can be advanced to almost top dead center the engine lasts longer because the minimal backpressure on the moving parts.

. I am still learning about this so I don't claim to be any kind of expert, I know a good bit of automotive but not what is needed to do the conversion yet. Any suggestions like yours will help, I have assembled a scattered team of guys who want to help with H2 and alcahol research and hopefully make some money on it while helping out the country

 

I have a power commander 2 on a 01 vfr800 can anyone help me find program and a maps for it?really need the help cause bike is stalling out and everyone says take it off but i dont want too lol,I wanna get my bike running at its best so.........please help!!!!!! im desperate

 

i have it the fuel ratio on pc2 do you know where i can find a map for 01 vfr800 interceptor(fi) i would really apreciate it
