I got my scanguage for various reasons but one of the nifty features is that it gives you some temperature guages. I have mine set up displaying intake temp and water temp.

Now when I'm stuck in traffic I can watch the intake temps going up and up....

It would be good if we could collect similar data for a range of different intake setups in different ambient temps.

I know that Shopman has done a bit of a study of his intake temps

How good is the intake temp guage? I would hope its supplying good data to the ECU, I wonder what the refresh rate is for the sensor

What I'm noticing is that on a cold morning the intake temp is a couple of degrees higher than the external ambient air temp read from inside the bumper.
As the car warms up so does the intake temp and it keeps going up. I see the intake temp rising quit high when in traffic. No shocks there then but what does surprise me is how long it takes for temps to drop when moving.

I do a journey of at least 30 minutes where the car is always moving, I see typical temps of external 6c, intake 14c and Water 86c. If in similar conditions and duration I'm stuck in a lot of traffic I'm seeing intake temps in the mid 30s but when I get moving it takes ages if ever for the temps to go down. That makes me wonder if the guage is accurately mesuring the temp of the intake air at the point of intake (about 6" infront of the TB) or just measuring the heat of the plastic intake. I've only had the Scanguage itted since Christmas so I've yet to do many miles, any motorway driving, a meet or drive in ambient temperatures above 10c.

In terms of fuel / air combustion what is considered cool or hot?

Could it be that we are wasting money on CAIs, cooling plates or snorkels to suck in cool air because the intake warms the air in the pipe?

I know this is nothing new in terms CAIs that many have and other mods such as the Hondata intake gaskets etc. but the scanguage is an interesting tool to measure this and there must be twenty of us here with them.

 

Dont remind me. lol

 

i've seen water go up to over 100 when in heavy traffic - 105 at one point, however, after less than a mile's gentle driving it dropped fast to 88.

intake generally around 30deg once the car's up to temp after 15 mins of driving ish, but again, in traffic i've seen it hit nearly 70!

I run with the air box lid off by the way.

 

My water temp average out 84. Since the installation of Spoon Fan Switch & Thermostat, my average is now 72. So a drop of 10 degrees.

Intake temp however I dont believe its 100% correct. The temp sensor sits on top of the throttle body of which HOT coolant pass through to prevent the butterfly from sticking, surely that affect the temp readings.

I have got a Spoon snorkel and sometime it reads quite high numbers on a cold day after a bit of driving. When I pop the bonnet, the snorkel feels cold to touch. Now I am no expert in thermodynamics, but surely the air cant get that much hotter (no more than 5 degrees imo) at the point of entering the thottlebody of which temperature is measured by the sensor.

 

Is the temp guauge that the ECU uses to monitor air temp on th TB or the intake ducting. I had assumed it is the temp sensor located in the plastic ducting at about the point of the bend.

There are differences in models. I remember when I fitted the K&N intake I had to drill a hole for a temp sensor and the instructions indicated it was not necessary on all cars, was it relocated?

 

On mine the sensor is on the manifold and it picks up the temp
Of the manifold as much as the incoming air, that's one reason
to fit the Hondata gasket as it stops the manifold from getting
hot and fooling the sensor
I ran a seperate sensor inside the airbox for a while and the
two readings were very different

 

The low fuel light came on with 55 miles left according to the scangauge, I done 35 miles and chickened out at 20 miles to go.....

 

Interestingly, the IA has no correlation to kangarooing.
I noticed it at many different temperatures so am still suspicious as to the cause!

 

Has anyone or can you fit the scanguage into the steering wheel, i have no idea of the dimensions just an idea...but it would be seriously cool and F1 like

 

Depends on if you want an airbag.
Or you would look REAL cool with a scanguage buried in your forehead.

Very ' Matrix' dude!
