View Full Version : Outside temp sensor trick

01-04-2006, 08:50
I live in a over 40C degree tarmac heat and would basically try anything to improve the clio's performance. Well, last night round about 11.50pm, I tried out something a bit unusual.

As some of you may know, the outside temperature sensor is linked to the ECU to tell it to switch mixture according to temperature. Hence, the drop in performance during summer heat. So, this is what I did, I simply taped an ice-cube to the sensor under the passenger wing mirror.

After about 11 minutes of fiddling with it, I test drove the car. And man! it blew me away! :shock: The throttle response was razor sharp and the torque was everywhere! :shock: I reckon my 0-60mph time must have dropped by over 1 second!!

You guys have to give this a try. Now, obviously, with the colder weather you guys would have to use more ice cubes. Maybe start with 1 cube, then 4 cubes and perhaps 06 cubes. Or even hang a whole bag of ice cubes under the mirror. I'll bet you will be surprised at the final outcome.

Cheers. 8)

I thought that little sensor in the pasenger side wing mirror had nothing to do with the mixture the engine uses? Just simply as a sensor that displays the temp on the dashboard.

I also thought the fact the car runs slower in warmer weather is because the air is less dense meaning a less powerful combustion?

Holy **** he aint wrong,

Just tried it on my car, weather is getting a little warmer around here too just popped out and tied a bag of ice underneath the wing mirror.

Car fooking flies now, cheers mate awsome tip :twisted:

Yeah, I am certain I have seen the outside temp sensor pin-outs on the ECU in the dialogy software. Will re-install the dialogy software again tonight and let you know the specifics tomorrow.

Hope everyone had a good 1st of April and that my little yarn has added a bit of merriment to your day.

And apologies if I had gotten your hopes up on improving your quarter mile time. You big fat doofus! :D
