This page is about how to control an evaporator canister - sometimes called as charcoal purge canister
The evaporator canister is ment as a temporary storage for gases from the fuel tank, instead of releasing them to atmosphere.
A simple valve controlled by GenBoard releases the gases to the intake given some conditions are met.
- low RPM
- low MAP
- warm engine
- closed-loop operation
- ... ?
Maybe with WBO2 closed loop control the condition becomes very simple.
Since we haven't seen much research/feedback on this (anyone want to contribute links or experience?) ...
I plan to install a solenoid to suck out the evaporator canister from time to time, using the same condition as for the variable intake with MembersPage/MarcellGal/EngineSwap/AirFeed : 1500..3000 RPM, 80..101kPa MAP. Actually planning to use same ECM output (a FET), but different solenoid (the 2 solenoid connected in parallel electronically).

Fero (or someone else), can you collect info about valve control that I believe was collected before but misplaced?
