Re: Got My Torque Converter ... and a New Problem...
Check out this link on how torque convertors work.

If you are in to drag racing, an auto with a torque convertor is SICK compared to a MT.

ZEX remote opener, bottle heater
Denso iridium 2 steps
Z tube, Amsoil filter
Spec Stage 2 clutch
JIC-Magic traction rods

autos also don't make mistakes, that is their biggest advantage people, MT's miss gears, shift inconsistently, and have various launch times (60').
you can bracket race and win all day in an auto tranny. Only the best can do it with a MT car.

Re: Got My Torque Converter ... and a New Problem...
hey guys this is a repost of what I posted in gene's T/C thread.... with a few additions at the end
I will still be working on optimizing this mod....
My pingingis a symtom of a tripped up ECu, as it now sees more load due to better coupling in the T/C (about 3% loss instead of what I can estimate to be 6-10% loss). Now, our car behaves mre like an MT with respect to being "connected" to the wheels more...
I, however, can break my Kumho ECSTA KH-11 (which are extremely sticky according to objective testing ans Survey results on TireRack.com) very very easily when I break torque and sometimes even if I don't!
This mod is just more complicated then we thought. Just another reminder that our cars are very ECU - centric, which makes sense. The ECU is just a must once you get into major modding.... as we run out of fuel map whenever we add more air or more load... Rememeber, we have 3 fuel maps in the ECU, 'optimum', 'normal', and 'safe'. The MAF, by detecting so much air, switches between these maps, but only between these maps... ad tunes the timing accordingly... There is no "continuous" adjustment of air/fuel mixtures depending on how much air is coming in.... it just switches b/w these sets of parameters to accomodate the prevailing conditions.
The reason that I mention this is that these settings (A/F ratios and timings) are all a function of LOAD, which has now changed on our cars.... The engine sees a "heavier car" now b/c of less slippage....
DaveO has also done this mod on his Sedan, albeit with a 2600rpm stall. And he experiences NO knocking... This leads me to believe that the variable that is not the sae betwee us is the Crawford plenum (which he does not have), as we both have a respective ECU flash with identical A/F mixture and timings. Just a little more tinckering required here for me....
Will keep everyone posted...
