intake temp measurement

[deaf_rattle]

Looking at measuring the intake temp on my supra (after i/c)
WHat do people use for this?


Cheers

dick smith do cheap temp gauge with two inputs that can read before and after or intake versus ambient

cheers, will check that out.
Would prefer something that can be hooked up to 12v if possible.

there is a couple of online US websites which have nice digital units, I brought one with a few senders for the various applications I use it for.

I had a couple of displays from Jaycar for the celica which were reasonably good, from memory I had to build a little voltage converter to run them. Biggest problem was the lack of a backlight, so I ended up getting some from a UK overclocker website, installed those ones in the MR2, also had to built a voltage converter (they're designed to run off the 5v supply inside a computer). For some reason the displays never worked, only the backlight did. I gave up then but I'll see if I can find the website again...

had a good look through the forum where I found them and I can't find them anymore.

i have found this at jaycar, although more information that i want and i suspect it would be slow to react.

Car Voltage Meter / In-Out Thermometer / Clock

This stylish in-car voltage and temperature meter features an attractive EL-Blue backlit LCD which is constantly illuminated when the car's power is present. The unit plugs into the vehicle's cigarette lighter socket for power but can be hard wired for permanent connection.
Two LR44 button cells keep the clock powered when the car's ignition is switched off.
Two temperature sensors monitor both the inside and outside temperature of the car, with the external sensor attached to a 3m length of cable. Min and max displays are recorded for both the inside and outside temperature sensors for ongoing reference.
A green LED advises you if the car's battery level is good, but it will flash and an audible warning will sound if the battery voltage is critically low. The LCD, however, will indicate a more accurate reading if it's required.
An ice warning is also available if you live in a cold area (based on zero temp, monitored by the outside sensor).
Great for drivers who frequent the snow fields!
A clock and calendar are also featured.
Size 140(W) x 30(H) x 18.5(D)mm.

What are you doing for your ECU anyway?

Surely the standard ECU isnt gonna like having a different sized airflow meter to standard, and different size injectors, and all the rest of it?

Only reason I say, is that if you are most likely going to need to get an aftermarket ECU anyway, why not get something that can do datalogging, and then just monitor intake air temps from there, given that IAT is already an existing sensor.

running stock ecu, with lexus afm and 550cc injector upgrade.
tried and proven set up.
