Historically it really hates crawling along in traffic...

 I know several people like that too

[feeutfo]

Tried re calibrating at 1.10 , 1.15 and 1.17. All threw an error LPG injectors open, check lambdas etc.

Set it where it was at 1.20 and no errors. Guess it was set there for a reason.

And yes, it was grumpy in traffic on the way home. Doh. Although not as bad.

Fine this morning. Pulled over to see if it would behave at tickover, after las nights re calibration and tweak the map. No problem.

I also found another reducer temp sensor setting last night that matches the temp gauge perfectly, and changed the gas temp sensor to read similar/slightly higher than the reducer temp.

Faultless on the way in to work. See how it is on the way home.

I'm not suggesting it would supply enough fuel at wide open throttle. It's a step to prove it's overfuelling at idle when cold. 

Just as a test, give it a cal at 1 BAR, then set it to switch to petrol at 5K or something, just to see if it removes the cold start symptoms.

EDIT: assuming it's not fixed, of course.

Yes I was coming round to that way if thinking last night. But ran out if time. Got called in as tea was ready.

I'll have a proper fiddle on the way home in heavy traffic. Thing is the window for playing with settings is only a couple of minutes before it hits 80c and behaves. And I'll have the doors locked in case some smack head try's to hi jack my lap top. Good old slough.

[feeutfo]

Much better. But remembered I'd put the switch over temp up to 50c
.... it only had a slight grump at one set of lights.

Played up like mad this morning. Same codes.

Had to reset eml three times.

[feeutfo]

Temp 0c

[feeutfo]

Re calibrated it, again. But this time in the temperature that is causing the problems. Around zero c.

It seemed better, but that means nothing. See in the morning. But it defo feels better at low rpm, at 1.7 bar, and doesn't throw a warning at wot in first anymore.

However top end is flat and lumpy in power delivery. Gives little surges. Wonder if it has all the petrol map yet. ..? Fuel trims are coming down to zero from +19 and +22.

[feeutfo]

Also there seems to be almost exactly 0.5 milliseconds difference in injector times between both banks. bank 2 being more.

At 1.7 BAR I'm surprised the injectors are managing to open properly! It's only temporary though (I assume) and if it cures it then the nozzles can be made bigger to be able to reduce pressure.

[feeutfo]

Hang on. Do I mean 1.17? ...

[Lazydocker]

Hang on. Do I mean 1.17? ...

I hope so! At 1.7 you'll need to rebuild injectors and replace bump stops very soon!

Spoke to Tilo today. He said its injector related, probably due to bad fuel gumming up the injector seats.

Tried increasing vap,pressure to 1.3, as his advice, and dropping multipliers to give 3.2 - 3.5 ms injector times. He said if that goes tits up, which it did, clean the injectors with carb cleaner, which I have done.

Refitted injectors, fired it up, instantly running at 3.0 - 3.7ms at tick over, where as it was 2.9 up to 4.5 and stalling. Re calibrated, settled down nicely, good strong top end now, where as my last calibration was surging at wot at the top of the rev range.

Fingers crossed.

Isnt the filter in the vap supposed to catch the shite that causes injector problems?
