No, I never did get a chance to try it, but if you have the oppertunity to, by all means do it!! I (along with many others I'm sure) would love to hear the results!! Do it up, and Comp, if you can get one of those switch pods for me, I'd be willing to buy one and pay for the shipping it it works.

Later!

How will this improved shifting affect every day normal driving?

Probably wouldnt effect normal daily driving muhc, but being able to use the performance function and change the shift points could help when blasting rice or others on the street.

In every day driving you will use more gas.

Ihave a 1993 SE and am wondering if any one knows if the wires are ran Since i cant check since it is too cold and im geting my master cylinder replaced. BY the way I do not have the console in my car

True.. If you left it in performance mode, in every day driving you would probably use more gas. In that case youd be best to put it in "normal shift mode" which is more like the normal shifting points of the SE and SSE'*. Just my .02

Ok, but this is the LAST time! Funny. Third time in 10 minutes, but I'll go into more detail here.

Performance shift in my car works like NORMAL shifting in a car without the option. Normal mode LIMITS my shifts. It works the opposite of what everyone was thinking.

Performance should be called normal, and normal should be called economy.

Running in Performance mode all the time doesn't affect my efficiency unless I use heavy throttle. Both settings shift at the same point unless under WOT. Keep in mind my shift points have been adjusted now due to the Jet, and it still works the same, just at higher rpm'* than before.

In short, the switch will LIMIT your shift points in normal mode, and act the same as you have without the switches in 'performance' mode.

Ok, Josh'* 93 SSE has none of the 5 magic switches on the console, including shift options. His car shifted at WOT at the same RPM'* as my 93 SSEi in Performance shift mode. When I switch to 'Normal' shift, my car shifts 5-700 rpms LOWER than his car at WOT. This was, of course BEFORE my Jet chip changed my shift points. We can't duplicate this now without me getting into my PCM again.

Now to qualify this.....our torque and hp curvers are different between the L27 and L67. The PCM may take this into account, so this might be normal. What we really need is 2 cars of identical powertrain, one with the option, and one without. Compare shift points in both modes to the car without the option.

Did anyone ever try adding the buttons on their car and did it work?

My 97 SSE has only the traction control, but I was in the console and found another connector in the wiring harness hooked up to the traction control, and that connector was not hooked up. So I know the wiring is there. Will it work if hooked up?

I talked to Deathrat about this a while back, he thought the code was not in the non-supercharged PCMs. I am leary about splicing into PCM wires, and I think I'd rather get a chip which will probably do the same thing. But good luck on finding out any more info on this.
actually only the 97'* with the L67 had the 4T65-E, the L36'* had the 4T60-E, and yes i can confirm from my mom'* 97 Y40 that it has the 60
