---- On turbo engines, carbon canister valve is only operational up to 100pka and not on boost. Therefore on full throttle the valve goes to 0% duty cycle and the valve should be openened on all occasions where the lamda is actually controlling the mixture,in which case it is a narrow band lamda,therefore on closed loop conditions. Unfortunatelly VEMS does not have any misc outputs that can have more options for setting such a valve,which is why im actually using one of the misc settings to open the valve (on/off type unfortunatelly) on deceleration where there are no implications regarding the driveability of the car. I tried on cruising and small TPS values to see if it works,but unfortunatelly the car does not run right. It would be a good idea if this was implemented in future vems firmwares to have: 1) engine temperature 2) duty cycle control of the valve, along with the rest of the misc output settings that are already there. My car is an Audi RS2 which i have tried it on. |
