Can I just throw in the already tuned power commander??

Seems like it’s just too easy to work but I have to ask the question anyway.

If I buy a track bike with a full exhaust system and power commander 3 with quickshifter and that’s been tuned..(Th bike is probably beat to piss) can I just swap the exhaust and plug in the power commander onto my nicer bike that haven’t been tracked yet that And has stock set up? Or will I need to Dyno the bike?

Does the Dyno tune the Power commander or does it tune the CPU? I’m hoping It’s just plug/bolt on and play. Both same bike same year 06 cbr600rr

Is the motor stock on the donor track bike? If you are 100% certain that the motor is untouched and stock, then you should be able to get away with it. If you're not sure, I would not risk it.

Honestly, the easiest solution is to just download the Dynojet software, save the current custom map so you have it, upload the Dynojet canned map for your bike with full exhaust, and call it a day. You're realistically talking single digit horsepower differences.
 

Scandalous

Hella legit
Power Commander is 100% separate from ECU tuning. You can swap the PC to another bike, but unless they're highly similar, you may end up splicing wires because the PC harnesses are made with bike-specific connectors AFAIK. Like Mechanik said, save the map in the PCIII for reference. FYI the latest PCV has way more options and is better value if buying used vs. older PCIII. As in, if you got one for the other bike too. Also, PCV allows use of Autotune O2 sensor and software to tune for correct air:fuel ratio. Nothing beats a good dyno tune though.

The seller said “he was told but can not confirm that the engine was overhauled to meet AMA standards.” Even if that doesn’t mean mild cams and new pistons that still would be unwise to transfer over the exhaust/power commander huh?

The price of the track bike is less then the worth of exhaust, PC, Dyno tune, Scott’s steering damper Alone and the exhaust on my bike is leaking like a sieve and I can’t seem to fix it. It seems like anything short of welding the mid pipe to the cat just won’t work. If I spend any time at all at 12k rpms whatever fix I use blows out. There are a lot of cool parts on the “doner” bike but if the exhaust won’t work it doesn’t seem worth it

You can just use the PC with the downloadable Dynojet canned map for a full exhaust. It will be fine, but it just won't be as optimized as you could get with a tune for your specific engine. The canned maps have a safety margin baked in for manufacturing variances. Again, you're literally talking a number that you would not even notice except on a piece of paper.

AMA spec doesn't really mean anything. It could be a stock motor, a superstock motor, or even a superbike motor. If the motor is non-stock, you may even be worse off performance-wise running the "custom" map for what is effectively a different motor than the canned map for a stock motor.

You should still see some gains over stock if you decide to run the canned map and exhaust on the donee bike.

Just following up on earlier question, PC doesn't "tune" anything. It plays mind-games with ECU and tricks it into changing fuel & ignition values. Process goes like this:

1. Put bike on dyno and do some "before" runs to gather AFR data

2. Analyse AFR data and determine areas needing fuel adjustment (load X rpm)

3. Make adjustment on PC. What PC does is change load-signal (TPS-position and/or +MAP for alpha-N systems) into something other than actual. So if spot on dyno needs extra fuel, PC "dials in" more throttle and fools ECU into looking at higher-load data cell on 3D map, thus injecting more fuel.

4. Go back to #1 to do "after" dyno run and repeat as many times as necessary.


Since there's limited amount of mods and limited amount of changes to airflow patterns, there's finite number of adjustments that needs to be done. Pre-made map off DynoJet's website should get you in ballpark. Yeah, you're not going to notice +/- 5% here and there.

itll probably be fine. most PC maps fix large issues with the OEM fueling and have tiny adjustments for each engine. thats how PC, Bazzaz, flash tuners, etc can provide safe base maps to anyone without knowledge of their engine.

I wouldn't do it if the track bike had aftermarket cams or a larger displacement. but it seem highly unlikely that someone wouldn't know if their bike had either of those.

I dont think this is right. I think the PC intercepts the injector signal and adjusts the duration, thereby changing how much fuel is injected. thats y it plugs in between the injectors. what you are suggesting is more complicated and more limited.

Agreed, piggybacks simply adjust injector duty cycle afaik. They only have two inputs to go off of, the TPS 0-5v and the RPM pickup.

I think it will be fine to plug in. A dyno run could fine tune it more.

Right on! I was told that I needed a Dyno tune to run a PC. It sucks the canned tune is $200 bucks but that’s much cheaper than a trip to the Dyno.

Thanks for the rundown. I knew it changed my air/fuel ratio but know how it changes it makes a lot of sense and helps a lot.

stangmx13: in regards to your statement about it being unlikely he wouldn’t know if the bike was highly modified: I agree but since it is unknown, I don’t want to risk my bike by taking the chance.

Powercommander maps are free from Dynojet. All you need to do is download the PC3 software and then download the tune map (or at least they have been in the past when I've used them. The last time I had a PC was a PC5 a few years ago).

You may be thinking of some other software package from Dynojet.

If yours is a PC3, it should just be:
Download the PC3 software
https://www.dynojet.com/downloads/power-commander-iiiusb-pciiiusb/
Then enter your 2006 CBR info and find the right exhaust, create a free account, and download

I beg to differ. :p Example? I downloaded a DynoJet map for the Power Commander on my K6 G1K years ago, engine was stock with an Akra slip-on. It ran okay but tended to load up at long stops (lights, i.e. extended traffic lights). Took it over to BRG and KC did a baseline run. The fueling was all over the place and pig-rich overall. After he built a custom map the bike was 100% better. :rboy

Before I downloaded anything, I would try it like it is. If it runs well, I would at least save that map in case the new one wasn't cool.
