megasquirt
on my mundano lump were 2 air temp sensors,1 in the rubber hose from afm to manifold and 1 in the ally part of the mani,any idea which one i use or
both?

both
intake air temp
and engine temp..
both important factors for generating the mixture..
mhh rereading your post looks like you see a hotwire as temp sensor..

hotwire and air temp
both are on the manifold..
hotwire measurees airmass.
make pics..

its easier for me to fly to the moon with 2 jags on my back than to post a pic on here
1 is in the rubber tube,tween afm and mani,other is bolted into mani,do i need both?

mhhh
as far as i know, the air temp is together with the hotwire assembly..
the srewed piece in the manifald couldn´t be a coldstart injector???
else just unbolt it and measure its resistance..hold it then in your hand and whil emeasureing..
should be easy..ÑD
a pic with the mobile phone??
infared to laptop?? cant be hard to make a pic! and once learnt you leanr more skills.. to! move your limits pall its 2006!

On my Zetec I had 3 water temp senors and one MAT (Mainfold AIr Temp) sensor.
The 3 in the water was:
one on a coolant hose which is for the temp gauge
one on the thermostat house which is for the ECU.
and one on the radiator which is for the radiator fan.
Hope this helps

hey my compo was made in the 60,s and i have tried to post pics but have never sucseeded.
i know one is incoming air temp,prob the one in the rubber hose,its the other one i,m woried about,my megasquirt wiring diagram shows 1 air temp
sensor and no map sensor.
i have the normal water temp sensors under controll as well

Just go get the GM sensor and screw it into the air flow early in the intake air flow assuming no turbo. Hookit up to the correct pin on the db37 and
you are set. What squirt is looking for is simple resistance that changes with an increase in temp. The GM one is pre calibrated and will make your
life simpler.

Use the one in the manifold. MS uses pressure (MAP) and temperature to calculate the density of the air inside the manifold. This can only be
correctly done if the temperature and pressure are measured at approxiamately the same position. There can be temperature differences between the
inlet system and the inlet manifold. These could cause the mixture to be off. A rough guideline is that 10 degrees celsius causes a 3% deviation in
air/fuel ratio.
That said, mine is between the airfilter and throttle because it was easier ;-)
You'll need to recalibrate the MS unit if you want to use the Ford sensor (not that hard to do, do a google for easytherm), or use the G sensor
like suggested.
Good luck!

In a Megasquirt intall if the motor is naturally asperated the location of the IAT sensor is not that critical and can even be in the air filter with
good results. Mounting deep in the intake can have more heat soak issues than the theory is worth.
