Thanks again I suspect this is a "dumb" ECU, and cold temps and atmospheric pressure changes are accounted for by applying a simple factor to the entire map.Scott
Like you say, the ECU has the ability to adjust the fuel/air ratio towards the rich side to accommodate cold weather riding.I'm not sure which sensor it is using but I would guess it is the oil temperature sensor located under the intake valves inlet port. (This is directly into the oil supply to the rocker arms).The sensor should give the following readings:-20* C (-4* F) = 18.8 kilo ohms+40* C (104* F) = 1.136 kilo ohms+100* C (212 *F) = 0.1553 kilo ohms By tweaking the resistance output between the sensor and the CPU, the unit might be fooled into thinking a richer fuel/air ratio was needed thus more power could be obtained.This might even be a switchable addition so when just puttin' around the correct temperature reading would be sent to the ECU and if more power was wanted the unit could be engaged by flipping a switch?
An ECU form Racedynamics was discussed a while back and has now been released, at least the website says so. http://racedynamics.in/products/powertronic
