Hi,
Just bought an 08 zx14 with muzzy full exhaust and power commander III. Bike starts and revs in nuetral, but when going above 6K rpm, she dies down. This cant be normal?
Any suggestions are appreciated,
Karl

First,

Second, why in the hell would you want to rev past 6k in nuetral???

If your bike revs past 6k in gear, what is the problem?

This is interesting?Hmmmm.....I'm with Dogo on this...WHY would you want to rev er like that in "N"?But not hitting past(or around) 6K is strange...maybe some sort of "safety" deal built in to the ECU?IDK.Will she hit 6K and above in gear?

Unplug your Powercommander and see if she still acts this way...that'd be my first check.

I know my '06 would redline in nuetral... don't ask.

Not gonna go check if my '08 will.

Hmmmm...hey Dogo.....didn't your first baby throw a rod or somethin?Hmmmm...just how many times DID you redline er in "N"?

Don't mind me...I'm suffering from a case of friggin cabin fever again....C'mon Spring....I needs ta ride baby!

Once... first time I'd set TPS on a PC3. That was 13k miles before she blew.

No worries... I know how you feel.

just because it is fun once on a while...a definite must for bike night.

Sure it will.

Couldn't find the vid where a couple kids sat and redlined a gixxer for like 2 minutes. This will do though. I wouldn't make a habit of revving with 0 load at the wheel but all sportbike engines are extraordinarily tough. I hear engines have been run for hours with NO oil before they finally gave in and blew.

If your 14 won't rev above 6K in N or in any gear there is something wrong. Sorry - can't be of much help beyond that. Hope it is something non-mechanical like a sensor is screwed up??????? I wouldn't be riding the bike until the problem is diagnosed/fixed.

Thanks for all your input,

I got my bike used 2 weeks ago and getting familiar with it. Called power commander support. The tech advised me on uploading a map (I had to do some cutting and pasting in order to dump the correct map -- long story) After installing a new map, everything worked great. There must have been an improper setting which acted like a kill switch above 6K. Thanks again!

This is way WAYY beyond me but sounds like you must have had some major Forked up A/F ratios. Probably superduper rich over 6K rpm would be my guess. Lean might have been a lot worse. Glad you got it figured out. Reminds me that I better be extremely careful if I play with my maps manually. Have to tuck that one away for future ref..

So problem is fixed?

What part # PC do you have?
If you had to cut and paste the map, then it sounds like you have an '06-'07 PC on your '08 bike. That works, but you gotta cut and paste the maps. Wonder if the map installed on your bike was for an '06-'07 zx14?

BTW, if you contact Muzzy, they will give you the best, non custom, map you can get for their system.

'06-'07 pc3 is part # 224-411

'08 pc3 is part # 234-411

Hi again,

More clarification: I have a PCIII on an 08 14 - just how I bought it. Got on my bike, and ran it in 1st gear after installing new map from PC. Thought the problem was licked but.. Ran up to 7000rpm and it's as if something kills the engine. The RPM's drop, then come back on but only to 7000rpm, then same thing happens. Can the map I installed (per PC recommendations) be causing such an abrupt loss in power??
BTW will PCIII work with 08 14??

Take the PC outta the equation... disconnect it... the main harness. Plug factory connectors back together. Fix the problem?
Yes, then the problem is with your PC. If the PC is grounded at the overflow, run a jumper to the neg battery terminal. Fix the problem? If not, get a new PC.

PC3 part # for '08 zx14 is 234-411

Keep us posted.

I grounded mine here. The screw where my thumb points. This is for the bracket for that bundle of wiring that goes up the left side of the bike.

Just used a little file to make suer there was some contact but the threads alone probably would have been adequate.

Thanks for the advice!

Disconnected the PC and plugged factory harness up. However, the heat level gauge kept fluctuating and there was constant fuel injection noise and the bike would not start. Thinking I made a bad connection, I tried again, spraying some electronics cleaner into the connectors, and the same problem persisted. Must be a faulty connection, but I tried to squeeze factory connectors as hard as possible under restricted confines. Same deal, then I reconnected my PC back as it was.

Another issue noticed was the gear indicator displays a higher gear than what is actually the case (shows 2 when it is in 1st gear) Got it on the road in 1st and everything works well up 'till 7000rpm, then engine sputters and will not get to higher rpm. I then squeezed the clutch and revved it freely and it kicked out around 9000 rpm.

Could this be a safety feature like a rev limiter?? Maybe the incorrect gear display has something to do with it. Or possibly 25F weather?? Or maybe all of the above contribute to the dilemma. Any thoughts??

Like I stated earlier, I purchased the bike used, and the guy had little technical info for me other than it had a PC. Would a wrong gear indicator be a culprit of a PC or some other 'add on' gizmo??
Thanks in advance..

some other 'add on' gizmo??

Does the bike have a TRE installed on it?
Ivans TRE installation instuctions
If so, maybe it's on the fritz.

If it is a PC3, I do not believe that maps for separate gears. The PC5 does I am told and the stock mapping definitely does.

Not w/o one of THESE.also.

Just curious, but is WOT set on the TPS in the PowerCommder setup program ? Cause it sure sounds like it isn't.

Maybe he said he reset it, and I didn't read it.

Didn't say, and good call, but that's ruled out since the bike still had the same problem with the PC disconnected.

The WOT set on the TPS is making sense. Maybe the bike thinks it is at a higher RPM and hits the rev limiter while at 7000rpm. I'll check into making adjustments to TPS and see if it solves my dilemma. Also, will look for TRE unit. From what I gathered it should be somewhere above the front sprocket cover.
Thanks,
Karl

"pulled the clutch in,revs to 9k"....The gear indicator could read off...using an aftermarket speedohealer.Or your speed/gear sensor MAY be dirty?

Makes really good sense... but if you disconnected the PC, and it still did the same thing, then that can be rulled out.

Factory mapping...factory TPS settings.It should work without the PC.It's something else.UNLESS...someone DID try to adjust the factory TPS.The contacts are both plugged in completely aren't they Knov?(at the right side throttlebodies)?I've another question here...may be nothing at all...but...how's the throttle free-play?When she went to 9K...was that wide open?Or just started sputtering at 9K?

Use a laptop and the dynajet software for
PC3 to a) upload a new map and b) set TPS according to instructions. Pay attention to part about hooking a 9 volt battery to it so you can set WOT with engine off.
