I am not going to copy the countless other threads on the countless other forums, however I do want to review the options....
On the 1125R and CR there is a solenoid, which when activated, closes the throttle butterflies a tad, to make the bike compliant with noise regulations.
During my brief flirt with an 1125R, I never had this happen to me... However, there are plenty or people that have had this as an issue.
There are two options to disable the controller:
1. Disconnect the solenoid
2. Disable it in the ECMDisconnecting the solenoid
The solenoid can be electrically disconnected by removing the driver's seat to gain access to the connector. It can also be physically disconnected by removing the airbox and disconnecting the cable from the throttle body...
The issue is, that when you disconnect, the ECM knows by two ways:
i. It sees that the solenoid is now open circuit
ii. When the controller should be working, it checks to see if the TPS has changed
In both cases (I know for a fact that i is true, but ii may be a myth), it will set the Check Engine Light.
You have two options to turn the CEL off.
a. Use a resistor (as shown in all the de-noid guides)
b. Turn the ECM error checking offUsing a Resistor
Check our very own Plumpton's How To - Here
Rhumor has it that the CEL will still come on if the ECM tries to activate the solenoid and the TPS doesn't change...Turn the ECM error checking off
You can gain access to the ECM with a handful of tools now. I am brand loyal to ECMSpy, and the PCSpy version 1.12.x will do the job just fine.
The data you are most interested in is that contained in "Error Mask Bytes" 4 and 5, check the ECMSpy website for it's location for your ECM type.
Error Mask Byte 4 looks after the physical disconnection (TPS) check
Error Mask Byte 5 looks after the electrical disconnection check
The Error bytes are organised as shown in the picture below.
So depending on firmware, you need to set the following bytes to the following values:
BUEZD 0x05ED 224 (decimal)
0x05EE 23 (decimal)
BUE2D 0x072D 224 (decimal)
0x072E 23 (decimal)Disabling the solenoid
The solenoid can be disabled in the ECM, just like the white wire mod, using the Active Intake Configuration byte.
So depending on the firmware, you need to set the following byte to the following value:
BUEZD 0x0287 3 (decimal)
BUE2D 0x035F 3 (decimal)
The question is, what would I
Answer is, disconnect the solenoid and set the Error Masks...
Why cant you just say what the resistance is so i can bust up an old tv set for the resistor,or can i just measure the solenoid and then bust up my tv. Also wont this get hot when it powers up.
If you take off your LH pod cover, you will see the same resistor terminating the CAN bus connector. You can measure the resistance of this one.
