Automatic Sport Button Question

[CB7Nub]

Is it possible to swap the sport mode from the 90-91 automatic cars to a 92-93 car? Like if it's just the ECU or something than yeah why not. But it's something in the transmission forget about it.

TCU plus wiring and switch.

Here are a few pics of a relocated sport button I did years ago.

What the hell is the purpose of that button anyhow?

I have only driven my brothers auto CB7 and never noticed a real difference....Maybe his is broken....thankfully mine is a 5 speed

It allows the engine to rev higher while under partial throttle. It's good in hilly areas, but otherwise it's fairly useless. That's why they discontinued it in the first place.

To properly use it, you will need the ECU, gauge cluster (TCU error codes will come through the S light, found only on 90-91 models), and whatever wiring/shifter/console components are on the 90-91 models. Plus, the harness may not have all the right plugs, so replacing the harness and/or adding custom wiring may be necessary. Not worth it for a fairly useless function, IMO.

Thanks Deev, probably not worth it if wiring is involved.

That sounds like a headache

Nice job on that relocated switch.

I barely use the Sport mode in mine. I usually leave it off, especially since I never really race my car hard off the line to ever warrant the use of it.

I might pop it into sport if I'm overtaking, but then I think it only works for the first 2 gears anyways, doesnt it?

what exactly does the sport button does?
