The following circuit could be used to switch between OEM and the TFI-1025.... a dual mapped TDM900, if you like... this might be handy if you need the TDM to be stock for a moment.







When the switch is in the up position, the TFI is powered on and the O2 sensor is out of circuit... The TDM900 will run modified, with the TFI-1025 setting A/F.



When the switch is in the down position, the TFI is not powered and the O2 sensor is in circuit... The TDM900 should run as OEM, using the O2 sensor to set A/F.



The switch could be waterproofed and mounted under the fairing, where it can be reached but not seen. Handy for EPA or MOT inspections.



I strongly suggest: Turn the ignition and key off before changing modes with the switch.

This is exactly what I have decided to do with mine, I've fitted it as per your instructions (velcro'd to the ECU and tapped the usual wires however I have left the power (red) disconnected for now until I fit my changeover switch). I'll set it up once the switch is fitted so that I can quickly go from standard to modified to compare how the bike is responding to the changes I'm making.



This is the switch I'm going to be fitting:





With this to keep the water out:





Should be all finished this weekend and I'll report back my findings...
