STV Removal

[D'Ecosse]

I found a schematic on SVDownUnder for a simulator (acknowledgement GrahamB) for the two wire (dc motor) type Secondary Valve Actuator/Position Sensor - I actually used this circuit as part of my GSXR gauge conversion.

I made some minor changes to original circuit design and designed a proper pcb layout, had it printed and sourced connectors.
Result is plug n play simulator that allows complete removal of the STV components - motor, position sensor, linkage, fast idle linkage, spindles & of course butterfly plates with no error reported to the ECM.

This is the result:

See short video of it in operation here

(truthfully not much to 'see' except evidence of no ECM error with the OEM STV motor drive & STPS disconnected.



Particularly effective if going with overbore throttle bodies.

Does it do the GSXR's too, could be a big market for you out there

Only the early ones - the stepper motor ones would require something a bit more complex!
Not sure where to even start with that one .....
