LPG Discussion Forum

Hi, i have fixed the issue!

As always, thank you so much for the answer! You are always super kind and helpful.
Problems were happening and first switchover even if engine was hot.

Solution:
Firstly i checked the new AT09 reducer, (i took it apart to seek for problems) and i saw the internals were ...

tried with another ecu i had (same model), no luck

ran a bit with this map, had the obd2 map out some yellow and red corrections (screenshot) and so i adjusted the map and we'll see tomorrow.
Also during driving it switched to petrol and back to gas... no error detected. im also uploading a screenshot with the conditions for switchover

Update: new screenshots + new test

Today's test: i used the car on petrol around 15 minutes, i didnt switch it on LPG, until later than usual, and switched with no issues!!! .. Map with small values was obviously too lean so i manualy adjusted to the values back to around 140 beacuse thats the car ...

yes. reducer pressure screw adjustor was checked and adjusted to 1.27 - 1.28 bar so the gas pressure centering bar was matching and green in color. (when engine is on, the software requests 1.28bar)

"MAP pressure" i havent checked... i think i cannot adjust that being the pressure inside the hoses ...

im back with a few screenshots where my settings are visible. engine was off so no live data (but the live data is visible in the first map screenshot above ( the one with with the bigger values).

Reducer appears not to be leaking. i also took it appart and made sure its clean.. its also almost ...

Ill be right back will all the screenshots. Yes, this map is unusual... first time seeing values so low. dont know what triggered them being so low... actually very likely because i autocalibrated it when it was running very rich due to whatever is causing this extremely rich problem.... im sure if ...

Promised pics below. I wonder how will fuel trims react now... look at the difference...

Beacuse the problem got worse yesterday and thus decided to write the topic, Today and went back and did the following tests:

Hi everyone, need some help with an issue that ive been encountering lately, on a very rare kit, but i have the diagnosis cable and software and i know how to work them.

Car: Dodge Avenger 2008 2.0 gasoline (4b11 engine like on the new lancer mitsubishi, like evo x but not turbo), very good car ...

hi, been a lot of time, just wanted to update:
First of all car still works excelent after 150000km on lpg with the fuel return and stag 300 isa/ q box basic (same plug, first ecu burned up and so i changed to qbox basic, its newer) Stag always helped me with suggestions, so if you are to install a ...

Update for the dodge case:
Very smart cars, they dont forget their fuel trims, not even if you remove your battery, so diagnosis playd tricks on me, as i was expecting a reset but actually the car was stalling and running bad on gasoline because the LPG wasnt mapped correctly and completley messing ...

Hi! Sorry to reopen this topic, but i have the same issue on a dodge avenger 2008 2.0i l4 (same engine as the 2.4i) with a Fratelli LPG kit. (I will return with pictures and injectors+ reducer+ecu names)
Problem is engine stalls in the aforementioned conditions, coasting or braking or pushing the ...

Mesaage #3

Pinj modifications are visible. They confirm the obd2 readings. All 3 injectors on bank 2 are being equally enhanced.

If bank 1 is actually reducing injection due to bad timing/clogged exhaust etc, wouldnt that mean negative corrections on bank 1?
Or bank 1 runnging too rich errors ...

Hi Simon, as always, many thanks for the quick and generous reply.

If i reset the ecu by unplugging the battery and elaving it for a while, and then strating the car so i can have a fresh set of data, LTFT both stay at 0, and the STFT bank 2 is around +2 or 3 at idle, and + 10 at 2500 constant ...

Hi! I will give an update as to what ive tested so far.

its still doing the fuel compensation (STFT +10%) on bank2, on petrol, at 2500-3000rpm, constant engine load (hill climbing for example).

i did a smoke leaks test, and the intake is ok
i will repeat the smoke test in the exhaust too (my smoke ...

Hi!
Sorry i havent been online.
I will post the details in a second when i get home, but i did around 3000km and the situation actually got worse, which is a good thing, as i can see its having the same issues on petrol. I could have sworn petrol was absolutely fine, but i noticed:

bank 2 had a ...
