I need some help in modifying my throttle linkage. Now my car is a 99 TA 6 speed with cruise control and traction control (TCS). It uses 3 cables, one from the pedal to the cruise control (by the air pump). A second from there to the TCS motor (by the battery). Then from there to the throttle body.
Now the problem is that the first 25% of pedal travel does 80% of the engine control. For instance, a typical up shift requires me to lift the pedal about 2 or 3mm. which is very dificult to do. If you are slightly distracted or under stress (think racing) the adrenaline can make you lift a bit too much and cause the gear to not want to engage. Trying to control such small increments in the pedal is darn near impossible. What I'm trying to figure out is a way make the throttle more sensitive at the early opening stages and then make it open quickly from 1/2 to full throttle.

Now I've noticed that GM reshaped the throttle body cams on the later style TB's. They made the top a bit longer to give more control. Unfortunately, they didn't compensate on the bottom, which means it uses a longer cable. The cable pull from closed to full open (90*) is slightly longer than the 98/99 throttle bodies.

My first thought was just swapping to a later throttle body, but the TCS motor seems to prevent a longer cable pull so I would not be able to open the throttle all the way. A TCS motor swap is out as they are extremely expensive. I believe my only choices are to modify the pedal assembly (not much could be done) or to mod the 98/99 TB cam. I need to maintain the stock cable pull length. Here is my idea:


Does this seem feasible or is there a simpler solution that I am overlooking?
