Does Crome use the air temperature sensor? I extended the wires for the sensor and plugged it into my Greddy air filter. I would like to just run a filter on the turbo inlet. Is this sensor doing anything?

 

it should. and the incoming air has a different temp than the intake manifold. so you may want to rethink placement.

 

Well Greddy built the temp sensor into the filter so shouldn't it be fine where it is?

 

it should b e ok. but it would be better to actually see what temp the air goin into the engine actually is.

 

place it closer to the throttle body on the piping.

 

If i do that wont pressure in the charge pipe blow it out?

and wont boost leak

 

If the sensor is an OBD-II style, since it is running a chipped OBD-I ECU, you can easily swap to a flanged type sensor and weld a flange on the charge pipe and place the sensor there.

On a few occasions, I just machine a custom adapter with an O-ring and set-screw so I can still place an OBD-II style IAT sensor on the charge pipe with no leaks/popping off under boost.

I try to avoid putting the IAT sensor on the intake manifold, or at the air filter. One will register heatsoaked readings, one will register ambient temps (and not your charged air temps).

 

Why would Greddy install the sensor there? I have always thought of Greddy as a good company?

 

The sensor was placed there due to simplicity, and good enough to get the job done. The IAT sensor is only responsible for up to 10% fuel corrections anyway, and GReddy kits aren't what you call best in terms of a well tuned turbo setup with a blue box they supply with the kit, or a basic E-manage blue.

 

How many SFWD champs you know used a off-the-shelf Greddy Kit for a Civic, let alone a fast Civic using E-manage??

They did it because the electronics they provide aren't exaclty top-notch in terms of precision or accuracy. Placing it in the pipes, on which they'd have to weld on a special machined flange at an overall high price for such a small performance improvement.

Cliffs: Greddy is just like any other company - they'll save a buck (or overcharge!) when ever possible. One only has to look at their replacement BOV diaphragms to understand.

 

So is the sensor being in the filter a bad thing in terms of my basic setup?
