I have a Power Commander II on my Hayabusa turbo buggy. The previous owner replaced the muffler on the buggy with a straight pipe. It sputters a bit at low revs. Could this be tuned using the buttons on the unit, as I don't have the software or the cable. If so, how is it done? Thanks for any replies.
-
Sounds like a question for masterfabr
-
Yes, Masterfabber, I steered him in your direction, Welcome Rodndeb...
-
Well I wish I could yes but most likely not.The buttons only enrich/lean the map across the entire map.You need to get a cable and software and some means of logging the A/F ratio.I use an O2 logger from Innovate and a DL-32 logger. I only use PC3 USB or I'd give you a copy.Maybe someone else can help you out on that.

www.innovatemotorsports.com (http://www.innovatemotorsports.com) . You'll likely only need/want a cheaper logger from them to just log A/F. You will definitely need the LC-1 wideband o2 sensor for measuring the A/F. Their website has tons of info. When it gets confusing just ask us for help or whatever.

If I'd get all my thoughts together I'd do this in one post.LOL!!! The stumble is likely from too rich.
-
Welcome new guy.
Is it possible to have it reset to a "factory" or default setting? Anyway to reset it manually as a starting point? Or send it off and reflash? BTY, I know nothing about them, just a general electronic device starting point....
PLEASE IGNORE ANYTHING I JUST SAID AND REFER TO THE NO NO NO below.

NO,no,no,no do not set it up with any map available and run it .There's really no such thing as a "universal map" for a turbo busa.He has the starting point already.It just needs tweaked.If he doesn't want to do it himself he needs to go to a good tuner/dyno and have it done right. GREAT info can be had here

It reminds me of my old vw buggy loading up and all you have to do is blip the throttle and clean it out. Will the spark plugs tell me if it too rich or lean? I'm new to fuel injection. ???

I sent my commander out to be programed. I told them what intake and exhaust i had and they programed it for me for $40. I cant remember what shop did it, I will try to find my recept and let you know. I think you can also go on the website and they can set up a fuel map for you and you can download it if you get the cable from them
-
It looks like Enemy is giving some excellent advice, I only wish he'd do it here... ;D
-
Punkur he's turboed.DJ doesn't have maps for that.Too many variables.

You can't read the plugs and decide if the stumble is from too rich or lean.
-
OH shit.I must have dreamed the turbo bit.I thought I read that it was.Maybe that was at the other place. Oh well!
-
It does have a turbo. I'm thinking of getting the new version of the power Commander and starting from there, so at least I'm up to date as far as hardware goes. Does the air/fuel meter just stick in the exhaust pipe? Or do I need to install a bung in the exhaust tract for the sensor?
-
-
That's better!

Weld in a bung and make SURE the exhaust system is free from ANY leaks.Otherwise the O2 readings will be useless.
-
Can the A/F bung be after the turbo or before it? BTW, it has a dump pipe type exhaust after the turbo. On a side note, I found out how to adjust the PCII using the buttons on the faceplate. I richened up all of the settings, low, med , and high. Runs much better/cooler now.
-
I'd like to see a followup report on this....

Always after and close to the turbo..
-
Whatever happened, any info????
-
Well, I found out that the settings on the Power Commander don't make
as much of a difference in the way the car runs as much as the adjustment setting on the Fuel Management Unit. I have the Begi FMU, and with the settings on low, med, and high on the PCII right in the middle of it's adjustment, the bleed screw needs to be 2 turns out on the FMU. This is the best setting I have found yet for there to be no off idle stumble. It runs nice and crisp all the way through the rev range. It makes me wonder if I should just take the PCII off and then try it, but I'm afraid to mess with it, don't want to lose my settings as they are.
-
The PC WILL make huge diffs! You DO need to get the finicky FMU just right AND KEEP IT AT THE SAME ADJUSTMENT. If it changes so will your A/F ratio and make it necessary to start all over again with the PC altering the map.
-
Quick question...
I'm using a PCII on my buggy and it has the same map that was on the bike with the M4 exhaust and airbox mod for the TL1000R map. My exhaust is roughly 2mm larger in ID and very close to the same length, but I have enormous K&N air filters on the it. So my question is do you think at the spring DTS meet you could give me a hand with the O2 logger from Innovate and a DL-32 logger you were talking about Fabr? I would get you good and drunk for something like that. ;D ;D
-
Still running PC II? now added O2 reader and DL-32 logger? I would ass-u-me rofl you can get the PC software from their website.
While I never used and PC software there is tons of software support, I ended up buying the Bazzaz unit and O2 auto tune. Very slick, simple, just have to remember to turn on log before some good running.

You don't need a DL-32 just to log A/F. I fiorget right now the name of it but there is a cheaper Innovate logger you can use. Matter of fact I think I have a new unused one if you're interested.

Btw,bribing me with alky won't work. I drink very little. You show up @LS and we'll talk tho!!!!!
-
you talk we'll drink or atleast i'll watch carl and transman drink the tank dry! rofl

LMAO kick kick LMAO
Fabr or Enemy will hook you up.

YEP! ;D ;D ;D rofl rofl rofl rofl rofl rofl rofl rofl rofl rofl
