boost lag and fuel economy question

[hunker7]

I can't remember whether you are reading boost from a OE digital boost gauge or an aftermarket analogue gauge. If OE digital and stock chips, etc. 2.2 Bar is max. If your ECU is chipped with a 300 kPa (3 Bar) MAP sensor, the digital boost gauge isn't calibrated for a 3Bar MAP (just a 2.5 Bar MAP) so the readings will be wonky and meaningless.

Mine is 250kPa map with stage 1 chip.

I might have found issue in regards to my boosting problem, I mean I found out the hard way, currently sitting and waiting for my brother to tow me back home.

R.I.P. Fuel Pump

Stick a new fliter in too

Cos it might have bits from broken pump?

Also, I had a massive cloud of blue smoke behind me when it wasn't running on all 5?

It's not the fuel pump after all, sparkplugs are all wet so it isn't getting spark, I got TFSI coils. Can't connect laptop as it says Port Status OK interface not found

Check wirig of coils, especially the ground which is bolted to the motor.

Wiring is good, and all the earth cables are attached and connections cleaned.

What could cause the blue smoke coming from the exhaust, looked like someone was pouring oil in the exhaust. Oil level hasn't dropped.

Ecu dumping in fuel for some reason? possibly boost hose split?

Have you had the plugs out on the cam cover? see if it's sparking?

I started car in the morning it started and stalled straight away, then I tried starting again and revved it, and it came to life, and then blue smoke was coming out of exhaust, I left it to tick over for a while and it was all fine.

Then I was going home and it was all good, when I felt that car looses power slightly every now and then, and then felt that some cylinders were not working, 2 by the feel of it, and smoke was pouring out then. After I stopped car was running on 3, then I turned it off and couldn't start back up again.

I will check the spark in a minute.

Hate to say it but I think you should check the timing again. At the flywheel, make sure iut hasn't moved.

Could you have a loose chip in the ecu or the ecu connector not seated properly?

[hunker7]

Spark is there, but 2nd cylinder is full of fuel.

[newsh]

Injector failed?

[newsh]

I dont have experience of this, post a new thread.. "Car broke down - cylinder 2 full of fuel" or something like that

[hunker7]

Injector failed?

Yeah, that's what I'm thinking. Dad is sending me a replacement.

Would that cause car not to start though?

I guess it's flooded
