Is it a new TMAP?

[Bargi]

Not hitting the side but looks to be flowing OK. (if it makes a difference only runs when engine is running. Even with key in on if the engine is off it won't run)

 

[fezzasus]

Flow rate looks okay.

 

The relay isn't triggered by the fuel pump then?

Will check, got it off Lee, so it's probably done the rounds

Have you got coolant in your cc water system ?? Looks clear

Yep, I had to raise the brightness and contrast of the pic so it would show it up, so will look washed out

[Steve.i.am]

Sorry to overload with graphs - but kinda interested in this now. Can you post a graph of inlet temp vs vehicle speed?

No I guess not, strange isn't it. Turn the key to On and you can hear the pump prime and other clicky sounds but no flow. 

What could it tap off for power?

Here's my flow

nothing wrong with your prostate

[Bargi]

this is about my car, not a pissing competition!

 

I'm 100% sure the TMAP is the 2.5bar one which is what it's set to in the OBDTuner parameters.

But am I right in assuming the difference between a 2, 2.5, 3 TMAP is just the pressure sensor and the temp sensor is going to be the same?

 

So in the off chance a different TMAP is fitted you'd get get correct temps just wrong boost?

My CC pump relay is driven off the fuel pump supply and mine does the same. When you turn ign on, the fuel pump & CC pump run for a few seconds then stop. When you crank/start the engine they start up again.

the temperature sender is just a variable resistor, if it has been damaged or there is a loose connection then the resistance will change so the displayed temperature will be different.

At least 1 check can be done relatively easy..

 

How hot does the coolant in the CC tank get after a brisk run? Perhaps check with an IR gun or a simple thermometer dunked in the tank.

 

I don't know how the CC circuit is set up, but if the tank on the return from the (pre-)radiator at the front, so should be pretty cool/ambient if the car was traveling at a decent speed and low-ish boost (good airflow through the prerad not too much heat input) right before checking. Perhaps cruise a little motorway and check in a lay-by. Probably heats up reasonably fast when left to ide though.

 

Or if the tank is mounted on the outflow from the laminova's and before the pre-rad: does it get significantly over ambient temperature? Aka, is there sufficient heat transfer happening from the air to the coolant in the laminova's?

 

Should at least give an idea if something is 'up' if the results do not match the expected behaviour.

 

Eg. if the 1st test results in 'hot' coolant in the tank then the pre-rad seems to do little heat-shedding for some reason and the whole CC circuit gets too hot. (prerad touching main rad?).

 

In the second case, if the coolant in the CC circuit coming from the laminova's is not getting much warmer than the intake then there may be an issue with getting the heat from the intake air to the coolant (dirty/oily laminova's?)

 

An additional (hand-held) temperature probe fitted right after/under the SC  before the laminova's would also be nice to get an idea of the pre-cooled temperatures from the SC in case the system is working, but where the charger is for instance  spitting out >90C air to start with.. (There's only so much heat you can get out..)

 

TMAP is fitted after the laminova's, right?

 

Bye, Arno.

[Sutol]

Where exactly is this temp physically measured?

[fezzasus]

Where exactly is this temp physically measured?

 

Same point as the MAP sensor, after the laminovas.

[techieboy]

Where exactly is this temp physically measured?

On your's pre-throttle body. On Ray's post-laminova.

[slindborg]

Could it be that the coolers need a clean out as per the service guide for the yankee cars?

ahh ok, that sounds right

By the time walk around it's stopped
