Re: Pop and bang on LPG

Thank you!
So in theory lpg will be safer for pop and bang as petrol at least for the bores.
Now i need to find someone capable of adding this mod on my petrol ecu map.

Re: Pop and bang on LPG

So you reckon that the lpg gas will be ignited in the hot exhaust and will crackle/pop as the petrol? In theory, lpg or petrol will be gas, not liquid coming from the cylinders?

Re: Pop and bang on LPG

"“Pops and bangs, or burbles as the OEM call it (yes, it’s that common on production cars that even the manufacturers have a name for it!), is simply a calibration feature within the ECU where we set up a specifically targeted, very lean misfire once you lift off the throttle.” Normally on an engine...

Re: Spark plugs

No, for my engine they do only platinum, but they mention reducing the gap. I was afraid of doing that.

Re: Mercedes C class w204

Yes the LTFT reaches 7% during driving, if I switch off the engine and put the key in the ignition I can read the LTFT properly. So if with the engine running LTFT is all over the place with the engine off I can get the exact value. Before converting to LPG the LTFT is was 3.1% on both banks, I am t...

Re: LPG burning temperature vs petrol

I was joking, I did that for the sound. Standard the exhaust is quite so doing that it makes it louder. I start by removing the baffle but it wasn't much louder so I went with cutting the bends in the back boxes and put flex pipe in there. https://imgur.com/a/7qAyb9b Cold start https://www.youtube.c...

Re: Mercedes C class w204

So if the LTFT is -1.6% on bank1 and -0.8% bank2 over 8k miles that means that the tunning on lpg is really good?
On petrol in an ideal world will be 0% ltft both banks.

Re: LPG burning temperature vs petrol

On my slk 350 i did 30k miles on lpg so far. Every year I do a compression test via DAS and I am pleased to say that nothing changed. Also, I have a stage 1 remap, 2nd cat deleted and straight pipe to dissipate the heat =))

Re: Mercedes C class w204

Hi LTFT use to change slowly, but after I update the car ecu the ltft is changing very fast like the stft, have you seen this on any cars? You can play with the program just select demo mode after you install and lunch the program. AGIS M210_P13 ver 1.51 installer https://www.acon.com.pl/pl/produkty...

Re: LPG burning temperature vs petrol

Thank you for taking the time and fully explain it.
Since I convert my cars on LPG I am paranoid not to burn the valves.
