Blanca needs HELP..

[smithabusa]

Its an indicator that something in your fuel injection system is unhappy, get out the manual and find out what code its actually giving you

[Blanca BusaLess]

Smith am I going to need a special tool to get it to give me the code.
Reading manual first time regarding this it seems like I may ?

Special tool (mode select switch) ?

Not sure on this as getting a code form it is new to me ?

[smithabusa]

my ecu flasher would show you on laptop screen, OR you can go to your kitchen and get a special tool "paper clip" and jumper 2 wires in the white sds connector under the seat.

jumper Test mode to ground
(white with red) to (black with white)

should give you an error code on dash, look it up in manual and we will see whats up

[Blanca BusaLess]

Ok I'll try that.
Right now my heart is recovering from the 'break' I just took.
Doing other thread now.
Something I promised my daughter !!!!!!!

Smithabusa can you check this link I found in search here and tell me if this depicts in pics what you describe above ?

Link here said it was a Gsxr but should be same for Busa ?

GSXR 750 K6/K7 Dealer Mode Bypass Guide : Suzuki GSX-R Motorcycle Forums: Gixxer.com

[smithabusa]

like i said couple posts up, white sds connector, 6 pin white connector under the seat

get FI light to come on with the 2 wires jumpered

[smithabusa]

yep, just like in the gixxer thread

[Blanca BusaLess]

Ok thanks .

With bike running or just with key on ?

[smithabusa]

[Blanca BusaLess]

Got the code .
c27

First pic key on , engine off
Second pic, engine running.

Ignition signal to #4 coil pack .
Wondering if somehow I did not get it all back together properly when I checked plugs or if this is the problem I am looking for from beginning ?

[smithabusa]

Running ob 3 cyl?

[Blanca BusaLess]

from left to right sitting on bike which cyl is #4 ?
Is it one all the way to the right of engine ?

Not sure as sometimes cyl #s dont always rhyme with where they are positoned ?

[smithabusa]

Right side

oK .
Let me ask you think this is still a PC prob or a code showing prob relating to coil pack #4which is going to be different from first thoughts of bad PC ?
Do we still suggest removing PC and eliminating it ?
If so how will bike run with PC eliminated ?

[smithabusa]

Fix coil see what happens

A messed up coil/misfire will also give you bad fuel mileage.

Smithabusa and Mr Brown as well as others at this point I just wanna say .

THANKS..

Because with your help and advice I used a 'magic wire' special tool.....to jump harness as you see and save myself $95 bucks in Diagnosis fees which is what the dealer told me it would cost to do.

Below is pic of white harness on right side of bike under driver seat.
Remove cap on it not just the little rubber plugs on one end.
THE WHOLE CAP unclips from it to expose open tabs to contact for jump.
Start bike, FI light came on , then it showed code on dash .

At this point I am going to take airbox off again as I did the other night when I checked plugs. I am going to double check all connections and make sure I did not cause this problem myself . If I find nothing obvious I am still going to investigate the TPS area that os taped to make sure all is well.

Question: 1
As you say Smithabusa fix coil and see. By saying 'fix' I assume you mean get a new one ?
Before I do that to make sure it is the #4 coil could I do a 'laymens' test and swap it to another cyclinder then see if bike throws code for that cyclinder that now has supposed bad coil ?
By doing that would it and should it narrow it down to that part ?
Question: 2
Smithabusa, Mr Brown was of opinion bar in the left of C code was in INCORRECT position for -key on, engine off- in first pic of codes above.
He was a little unsure of this on GENII. I see in manual it talks about this on page 1C-4 , TP sensor adj page.
Can you advise on this ?

[smithabusa]

if u have had airbox off better make sure your vacuum line to map sensor hasn't came off, bike will run awful and super rich if thats the case, make sure its still connected electrically and with vacuum hose, its bolted to airbox

make sure #4 is plugged in and seated on plug, i would bet money against it being bad, but its setting fi light for some reason

[Takeuon]

Gotta love the help you get on the org!

[Blanca BusaLess]

are you refering to IAP sensor and little vacuum hose that goes on airbox right next to it ? Page 1D-6 step 2 in air box removal procedure .
