several months ago i took alda off my 87 sdl,car runs great without it,except i get a flare at 1-2 upshifts.anyway to correct this.would putting alda back on with screw turned almost all the way ccw-still give performance without flare?

Yup.....

You'll need to re-adjust the VCV to give a harder shift...

For the same throttle-seeting (peddle-position) the engine is developing more torque--Which will need accounting for by adjusting the VCV...

what is the vcv,are you speaking of vacum modulator

i began reading about the vcv valve-most of the threads are about vac leaks or boost pressure issues ,how do i adjust for different throttle response after alda removal ?remeber this is a 603 engine

okaty after rereading alda removal thread i will try to adjust bowden cable first.where exactly is it anyone have pic on a 603 ?

The picture is here what are symptoms of b2 piston failure

The green circle is the adjuster. The red circle shows the accordion bellows around the cable; inside it is a small "pull" cable like a bicycle shifter or brake.

The bowden cable is for shift points, not shift quality. A flare in a tranny is either caused by too much vaccum present or internal slippage.

The VCV in the om617 anyway, is set up to release vacuum more according to how far the accelerator pedal is pushed. WOT means zero vaccum to the tranny resulting is hard shifts.

I do not know the om603 set up. Does it have a throttle position sensor?

thanks for the pics -very helpful.on reading alda thread ,trans shifting issues were mentioned after removal of alda,less throttle is needed after removal thus alteration of shift points ,i will try tightening bowden first then move on to vcv

Blue UFO looking dude on the driver fender by the ABS box is what controls shift firmness. Put a vac gauge on it, as throttle increases vac to it should drop accordingly.

ALDA removal on the 603 w/ intake manifold on is a pain. There is not a huge difference between it off and maxed out adjustment wise, just from what I could tell.

Be sure your boost is to spec on it, it is around 13-14psi on the 603, higher than the 617. And it seems usually these cars are always down on boost as the wastegate springs wear.

yes ive been thinking of putting it back on screw maxed out,but wouldnt it still affect shift points.i will check vacume a t blue disc

The only reason I can think of to keep it on is for the overboost protection.

Mine never changed WOT shift points/timing. You could have vac leaks in the system under the hood.

check alda removal thread-many mentions of trans shift changes after removal-i dont think its leak-i have no vac leak problems with shutoff,doors etc.but ill start with easiest change first -bowden cable

Leave the Bowden cable alone. It only changes shift points (early or late) according to throttle position, not the quality of the shift. Vacuum is what controls softness (flaring) or firmness of shifting.

i think i may not be useing the right term,my shift points are the problem,shifts too early ,not really sure what flaring may mean.
