Temperature correction
Morning all,
With help from Matt_gsxr I've been tuning my 2.0l zetec silvertop, its on gsxr throttle bodies with megasquirt 1/V3.
I'm using tuner studio but we had a problem with the temperature readings from the standard ford temperature sensors. They're not
calibrated.
Does anyone have the files or advice on what to do next please? any help is fantastic.
Thanks in advance,
Chris

You can either calibrate them with Easytherm (you'll need a thermometer, a multimeter, and cold & hot water), or replace the bias resistor
on the board for the one for Ford sensors (it says what that value is in the documentation, I can't remember what it is though).

The values for the Ford sensors are listed in the Haynes manual for Mondeo. You then need to punch those into Easytherm and it'll generate new
.inc files. Remember these have to go into the megasquirt itself AND into Megatune.

So I need to download megatune too? I've only got tuner studio at the minute. Also, where do I find the megasquirt software? I've bought
the car, so do I have to wirte them to the ecu?
I'm confused.
Cheers,
Chris

I unscrewed the sensor out the thermo housing, plonkled me camping stove on the scuttle and set about boiling some water with the sensor and a
thermometer in it, lappy connected, ignition on, fine tuned all the way and back down. Some ice round the sensor provided the +/- 0 value.

I've got the figures for the standard ford sensors, i managed to find them in a previous thread on here.
I've downloaded easytherm, I'm just not sure what to do next, I understand somewhere along the line that easytherm creates some files for
me???
Cheers,
Chris

There is/was an easytherm guide, but i'd have just replaced the bias resistor.
As its not going to be an uncommon mod, there's bound to be someone with that Ford sensor file (may even be in the download section of the
extraefi site - sure i've seen it somewhere).
Long live RWD...

Hi, i would change the bias resistors and leave the correction values as standard, most ford sensors require a 27K resistor, one for the air temp and
one for the water temp, R5 and R7 on a V3 MS
