Smoking On Warm Start Up?

I only smoke when my car is cold.

But, if you have some smoke, how long has it been happening? If you have worked on it recently, it'd be grease or oil burning off as it gets hot. Even a dirty hand on a dump pipe can make a noticeable amount of smoke when the engine is hot.

Is the image supposed to be related in any way?

hi there the image is just of my mate sticking his head in the way as i was fitting my FMIC ,as far as i know its only started to happen about 6 weeks ago ,it doesnt blow any smoke at all and runs good on start up when cold but after running for a while and i stop then hop back into car and start it up it doesnt want to start straight away when it does a puff of smoke comes out of the exhaust and thats it ,you can rev it up and get none ,it idles good and has full boost ,only owned the car for about 5 months if that really happy as its my first r32 but its only an auto but breaks traction in first three gears which i thought was bloody good so im bit concerned about this i dont drive it very hard at all as it has new tyres etc

Ah! Different story! I thought you had smoke in the engine bay or something... so that pic is completely unrelated in every way to the question. =-p

Ditto to Green s13... I wouldn't worry about that. You'd get plenty of that if you back off at high revs. Exhaust soot, basically.

what colour is the smoke, you say it doesn't start straight away if the smoke is black then it is just unburnt fuel from trying to kick over

smoke colour is bluey white only comes out ater its been run then turned off for a while then started then puff out it comes thats why i thought it mite be valve seals like oil getting into engine when warm then it gets burnt when started also in the last week or two ive notice black bits like soot on my back bar after given it a gut full on the way home from work

      If you take the top half of the intake off you can unbolt the flap off the shaft and leave the shaft in there blocking the hole. Then you can remove the little vacuum canister off from under the manifold and get a spare vacuum line to run to the ECU. I can take some photos of it later. Probably best to get the vacuum source to the ECU sorted first though. Mine all worked mint with the base map from the GTT an I've pretty much let the closed loop sort the fueling and took 1 degree out of the whole timing map.

      This IS something you also have to configure in Haltech (or at least I did in the past when going from onboard-to-ECU map sensor and an external MAP sensor in haltech land).

      I'm hoping it's something as simple as the ECU is looking for an external MAP sensor, but he is trying to use the onboard MAP sensor.

      You won't need to do that if your happy to learn to tune it yourself. You 100% do not need to do that. It is not part of the learning process. It's not like driving on track and 'finding the limit by stepping over the limit'. You should not ever accidently blow up an engine and you should have setup the ECU's engine protection to save you from yourself while you are learning anyway. Plenty of us have tuned their own cars, myself included. We still come here for advice/guidance/new ideas etc.  What have you been doing so far to learn how to tune?

      Put the ECU's MAP line in your mouth. Blow as hard as you can. You should be able to see about 10 kPa, maybe 15 kPa positive pressure. Suck on it. You should be able to generate a decent vacuum to about the same level also. Note that this is only ~2 psi either way. If the MAP is reading -5 psi all the time, ignition on, engine running or not, driving around or not, then it is severely f**ked. Also, you SHOULD NOT BE DRIVING IT WITHOUT A LOAD REFERENCE. You will break the engine. Badly.
