I dont 'get' the thread in Redlines sig... It does not actually show what to do?

But regarding changes... if its outside the stock systems parameters... nothing will help unless you reduce the intake/ exhaust sizes.

Contacted Yoshumuria RD and was advised a reset of the ECU was not nessary.

Could you post a copy of the e-mail?

I'm anxious to really know what should be done. I ordered the M4 2 days ago and i'm dying to slip it on

 

[Redline]

Slip it on.

Ride around for a week or two.

Then Reset the ECU.

Report back to us the difference.

Talk me thru this resetting the ECU Redline?... all your posts about it are not very clear.... Fuel injection takes about one millisecond to adjust.. unless you have a power commander or similar?

Sorry, my Honda dealer had to do it. Wasn't exactly a short and simple process for them.

They uploaded a tutorial on youtube.

First part is

Personally I'd get the dealer to do it unless you really know what you're doing.

They'll have it in their shop manual, pages 89-93 iirc.

Nice nice, But I wanna see the actual manual as well lol

 

[Redline]

Think there's a downloadable one, well, one that somebody (Saik on cbr250.org) photographed each page and put it together as a PDF. Link to it should be somewhere on this forum too I think.

Yeh I got that one, but it is a little incomplete

after watching the videos Redline posted from his dealer these are what I feel are the steps to go through when resetting your ecu


Step 1: remove ecu by removing righ side fairing.
Step 2: unplug ecu and wait 5 minutes
Step 3: plug ecu back in and turn engine on for 5 minutes. rev engine to redline a few times
step 4: locate wire loom running to tail light
step 5: with a piece of wire jump the connection between the blue and green wires
step 6: with the wires still jumped turn on the ingnition. wait 5 seconds then remove the wire you used to jump the connection.
step 7: your check engine light should nowbe on (solid)
step 8: turn ingnition off
step 9: locate and remove coolant sensor. located above engine under the seat.
step 10: jump the blue/yellow and green/white wire
step 11: with the wires still jumped turn the ignition on for 10 seconds. the check engine light should now be flashing
step 12: with the ignition still on plug the coolant sensor back in
step 13: turn igniton off
step 14: turn ignition back on and start engine. check engine light should come on then go off as it normally does. rev engine to red line a few times.
step 15: turn engine off.
the ecu is now reset.

Hey Guys,

I have a two bros in the mail and will install when it arives.

Do I need to do anything after installation? There seems to be a bit of banter on resetting the ECU but want to know if this is realy required.

Could you post a copy of the e-mail?

Sorry I already deleted it. Dam wish I would have thought of that. Sorry
