IM running a 12a custom turbo project and im using microtech lt8-s i was wondering what air temp sensor i need for this and also placement of it. with this go at down pipe like an o2 sensor would. if so which sensor i need? im running an s5 water pump so i could use the oem coolant temp sensor but i need plug for this one . here is a pic of the engine.

The intake air temp sensor definately doesnt go in the downpipe,you want it in the intake tract to measure the temp of the air entering the engine.
After you figure out what sensor to use(check Microtech's website)....what youll have to determine,is where Microtech recommends taking the reading from,before or after the turbo.
Before will give the ECU the temp of the ambient air.
After will give the ECU the temp of the air after being compressed and acted upon by an intercooler(if used)

Typically,Id say the temp of the air after the turbo and IC would be more important,as that will be the temp of the air the engine is actualy injesting.However,some systems (like the TII) have air temp sensors both before and after the turbo.

sry i ment ic piping not down pipe. i seen them on the plenums but i was looking for best location and wich one to use. as far as going to microtech website or even looking at the manual they have no actual reference as to which one to use. thanks for the help steve.

I put my intake temp gauge sender on the TII TB adaptor before the butterflies.....just like the stock TII EFI intake temp sender is.

Its after the IC piping,but before the throttle body.Itd be best to measure the air before it gets split into the individual runners,reversion will coat the sensor in oil and fuel.
It was easy with the aluminum TB adaptor,I just drilled and tapped it with a 1/8 pipe tap and screwed the sensor in.Many Honda intake systems just use a rubber grommet and a plastic push-in sensor,which makes install into an IC pipe easy since you just drill a hole and pop it in.

The big question is going to be what resistance values the Microtech ECU needs to see from the sensor.That will determine what sensor you use,and what type of mounting system to make (screw-in or push-in).......someone with a Microtech will have to chime in,since I only have experience with the stock ECU.

I'm running all the stock TII sensors with my Microtech.
