vanos etc.."
Bro, are you sure for the vvti, because you need another table map for this.
Not vvti this time.....or may be vvt on Toyota Siver top/Black top.
You quote:
"To my experience with MS1, A/C still works fine without any of those controllers, unless with high cam or 4 throttle. Even those branded standalones too have no proper servo controls. What do you expect? You want the manufacturer to design a controller to coup with every type of servo?"
Bro, sorry to inform you, i have to correct this ( A/C ). For air cond loading, you do need a big air valve ( on top have a screw ) like, Toyota Levin 4AGE, Toyota Starlet,even a modern Toyota SEG 4AFE ( on top look like hex ), Toyota Silver Top....Nissan E15T, Nissan SR-20...Honda VTEC ( behind the intake manifore )....
So, when A/C turn on/cut in, the engine rpm will drop at least 500 rpm. In order to maintain idle rpm ( say at 1000 rpm ), the the air valve will swith on and bypass more air to the engine in order to maintain idle ( off couse , fuel have to add also, or you can use map loading ).
Off couse, there are two ways to do. Simple connect the air valve wires on the A/C clutch or connect to the ECU ( which is support )
For Mitsubishi, you have to use stepper motor or servo ( off couse, you can mod and use big air valve )
Nows aday, if you see carefully, modern engine to need a air valve and modern engine like Campro,"drive by wire" ....i mean too advance...we can forget about it...just mod the throttle body with "foot cable"
Ah.....one thing....please do not use the "normal" air valve which the hole too small for the A/C to maintain the idle ( may be it can up to only 50 ~ 100 rpm )
If i am wrong, please do correct me. After all, we just try to help...and you know, thats why eraser always on top of the pencil...he...he...he
Good Luck.
