IAT Relocation?

[-=Jeff=-]

So I have all the pieces to do this..

BUT

where is the BEST place to relocate it to? when it is relocated what am I changing in the Calibration?

There is a hole in the air dam/intake for the radiator.....sensor fits well in that location

Approximately where is the hole? is it in the lower air dam that runs across the front? (if so mine is not stock)

or is it on the side of the air box?

Its in this area, Mr Haibeck has a bracket he makes I believe

I think Dom did this mod as well. Also -=Jeff=- he can answer your cal questions on what table changes

Yeah I figured he would when he sees this.. Dom moved his sensor into the airbox I believe.. I have the pieces may as well do it, but it in the right place once

Unless you modify the cal to reflect using an IAT rather than an MAT, not sure what the point of the relo is. With no change the ECM will use the values it has for cooler MAT, essentially what happens during warmup. Once you do that, you'll want to check the VE tables.

So a waste of time to do?

No I didn't say that. But I think it was one of those things, like the TPS switch, people did because they didn't have access to the cal for richening things up.
Having said that, you need to change the cal so that it works with an IAT not an MAT just like other mods. The table needs to reflect that. My sense is that the advantage is for a more consistent fueling based on Intake Air rather than using a sensor which could get heat soaked and so introduces a false reading. Just playing around it seemed to me that I was getting a more consistent AFR w less variation. BUT, the cal needs to be modded to accommodate that.

SO which table will I be changing if I move the sensor? (prior to playing with VE)

It's the SD MAT Compensation. We probably need to coordinate getting that into the $8EA def. Not sure I've done it yet.

No rush..
