I have just read the tech article on here about installing a
switch to lock the torque convertor manually.
Claims it helps performance, but.....

on so called performance chips, they change the programming
to delay convertor lock up, which kinda goes against what
the switch will do for you.

So.. what is best for performance, delaying lock up like
on the chips, or
using a manual switch (like in article)to lock it up earlier?

Bit confused here, so could you enlighten me into
whats best?

 

I think the main reason they delay the lockup is for driveability. The way mine was set up factory, at about 40mph the converter would lock and unlock constantly which was annoying. Most chips are programmed to a little faster speed to avoid that.

I've heard locking up the converter in second gear can be good, because you don't have the power loss through fluid coupling. My friend locks the conv. on his Turbo Buick in second and usually picks up a few mph in the 1/4. I think though if its a stock converter it may eventually damage the lockup clutch. Aftermarket converters usually have a heavier duty clutch in there.

 

Yea, it would probably wear the thing out, but do you think i
would get away with it, if it was just used occasionally, like
the odd time its taken to the track.
