fuel pressure regulator , static pressure or indexed to manifold?

[smiley]

If joe fitted the tmap, the old sensor wiring should be gone from the pipe between air filter and throttlebody.

Can you check?

 

[pete-r]

Peter can you send me a copy of your base map And also chrisP duck to I will compare the cold start setting within the software to the setting I had with my stage 2

I just sent you two maps and log files. Cheers.

FPR connected to boost on mine and map set up for this configuration.

[vocky]

so could it be the walbro replacement fuel pumps not priming quick enough causing the starting issues 

[siztenboots]

its trying to explain why its okay with standard ecu firmware

[Chris P Duck]

Possibly, does Bargi have a Walbro? Strange how it works with the CS map and not OBD though 😖

I'm going to look at the cold start setting on peter map now And compare it to my old stage two settings which I had no issue with Give 10 mins

[vocky]

simple test - turn ignition on and whilst pump is priming push start button, so only one second delay between ignition on and starter button press

Peter R setup is setup for tmap 2.5 bar was this installed?

[Chris P Duck]

At idle all other cars sit about 10% open while the problematic ones sit at 17%

Balls, this will teach me to assume mine was the same and not check.

Peter said my TB is actually more closed than normal. Looking at my logs my TB is around 6% open at idle. (Assuming pos throttle valve is the position of the TB butterfly?)




PS logs sent Chill.

The map deltas are different between mine and peter-r

 

will have a look at chris P ducks now

 

 

 

mine is at top

lsj is not listed and not supported by dutch software 

 

what bar is it 

[Bargi]

Its a weird one. Problem with std CS stg 2 setup with MAP sensor I was getting the problem. TMAP months later and still the same. I wont get a chance till early next month to try swapping the TB.

[CHILL Gone DUTCH]

These are the listed  map sensors

Just tried (finger ready on starter and hit the moment the fuel pump finished priming, 8 seconds of cranking then spluttered to life.

[pete-r]

I've had a look at the pipe work, the fpr pipe comes off the end of the rail, back and into the inlet manifold. Also I can see the sensor on the manifold the part number is 0261230042. Not sure if you can tell what bar rating it is from there? Also I send Peter my data and he came back with this which could be relevant? "I did see you have a P1512 (Throttle Position Minimum Learning not completed) at one point in time. This is the ECU complaining it did not complete the throttle position learning which could have a negative influence on the starting behavior." This is all completely over my head so I'm hoping you boffins can help...
