I got the springs for K1 / K2 installed and what a difference! It shifts relatively normal if you just cruise, but get on it and it shifts FIRM, not harsh, but nice and firm. I have not tested with max fuel yet, but it should make a difference their too.
It is too bad that I had to buy an entire kit for $55.00 and I only needed two springs. If any one wants to firm up their trans and needs some springs, I am willing to sell for a few bucks each.
I have also been working on a solution to my bypass valve operation. I was having an issue with the bypass valves fluttering because of the pressure dropping and the valves closing and the cycle repeating - the boost gauge would bounce and you could hear the S/C making a "woo woo woo" sound... as the valve opened and closed.
I designed a new circuit that is working really nice, it is the best it has run since the S/C was installed. It uses two micro switches, one pressure switch, two relays and a solenoid valve to control the vacuum signal. Below is the schematic:
I know what some are saying, you can do that with vacuum valves, you don't need to use all those electrics...well I prefer to use electrcial controls, that is what I do for a living and it is very easy to work with.
As I drive and the boost gets to the set point, CR1 energizes and is held by an aux. set of contacts. SW1 is a reset that is activated when the throttle linkage is at rest - idle. There is an additional switch for WOT that closes the bypass valves and allows for the S/C to pump some air to the turbo. I have also incorporated a switch to bypass the system when I drag race.
Before this the car would cruise on the freeway at 65 and the boost would be at whatever I had the pressure switch set to. Now it will be at 3 psi and when I add fuel the turbo starts to spool and we have boost, If I floor it, the boost comes on instantly from the S/C.
