Relocate air temp sensor

[nikp]

This may be of interest to people who are fed up of their air temps heat soaking when sat in traffic.

I believe that, even if you have the original plastic elbow, a nut on the inside should hold the temp sensor in place, but it does depend upon how much thread there is in the sensor.

Very nice find nik :Thumbs-up

Worthy of a sticky :)

Never put a nut on the inside!!! If it falls off its in your engine and out through your wallet!!

There is enough plastic. Its a M10 x 1.25 thread.

what do you mean by this? you mean put a tap into the plastic, and screw into that?

[rx7veilside]

buy a greddy elbow much safer tapping into alloy than plastic

Hi Nik. I've tapped a plastic one and a Greddy type elbow. Both have held at 1.1 bar. Use a rubber washer and nip the sensor up.

Cool - nice one. May be brave enough to try that on mine. Still need to sort the wiring on the sensor i got off you!!

I am trying to find the right plug to fit the sensor.

If anyone elso wants one of these high speed sensors I have few left please PM me or ring 07779 11 69 43 and I'll post one to you.

They eliminate the heat soak problem completely.

Regards,

Jonathan

Nik, I'm working on getting you a plug.

Anyone else need a sensor PM me.

They eliminate heat soak.

I could do with a plug too Jon if you find a source.

Jon, you have PM.

Cheers,

is this or a triumph one advisable with a stock ecu?

how does this benifit by seeing colder or realtime temps or to put it the other way what effect does a heat soaked high intake temp have?

cheers

Jonathan F, Can't PM you mate your not a full member???
Anychance of an email with all the prices etc for the new sensor???
My email is: info@d-signstudio.com

it means that the fuel mixture is aulterd more than it need be.... basicaly a quicker reacting sensor will give a better fuel mix ofor the intake air temps!!

Hi Guys,

Sorry, I've been away from the forum beavering away in the garage.

Jono - your right, by reacting more quickly the ECU should be able to fuel the car correctly more of the time. I work for a motorbike company and I've questioned some of the fueling guys. Their supposition is that the slow acting sensor Mazda used is either a throw back to the non-turbo charged engines when changes in inlet temperature would have been due to ambient changes and relatively slow, or, they have used it to smooth out the engine. I imagine that from a heat soak to 20 mph scenario (at the lights after a blast) as the sensor(my fast sensor) cools rapidly you get a change in fueling from rich to correct and the engine response may change - feeling non-linear. This would of been a negative for test drivers etc. Its only a theory. I'm purchasing a logger + wide band AFR so shall be able to log the two sensors later in the year.

In the mean time, e-mail me at Jonathan.f@hotmail.co.uk if you would like a sensor and plug. I can also source a small bolt that blocks the old sensor location if you want to relocate to the elbow (where heat soak is less evident).

Regards,

Jon
