Does anyone know what the latest software is for Motronic 4.4 for the b5254t manual? Have there been any changes? According to the gtp chat, I have the oldest version. Apparently, the newer versions have better idle control, STFT control, and no longer have sporadic misfires.

B5254t. What does blue smoke from the exhaust mean? It only smokes when the engine is warm, when it runs for several dozen seconds at idle speed and after increasing the speed.

An update on my 10-year battle to find the cause of "misfiring". I recently changed the LPG computer to a newer model from another company. I was surprised when the LPG program showed the error "gas injector fully open" from time to time. It was firing on various cylinders. I tho...

Does anyone know at what air flow the wastegate starts to work? B5254T 142kW

The lowest value in the photo is 17.9 kg / h, which is almost 5 g / s. I have checked out of 5 used flow meters and none showed more than 3.6 g / s. The inlet is tight, I checked it under pressure. It only hisses in the hole on the underside of an intelcooler that appears to be factory.

Or similar engines.

What is the correct air flow values g/s in B5254t?

Unfortunately, it is impossible to convert the original regulator so that it charges more. Adding a diode t...

I was finally able to improve the charging on the S70 / V70 / 850. The original Untitled7_20220402210811.png regulator charged max 14.1V on the battery, but on average below 14V. I used a regulator from BMW, which looks similar to the factory Volvo. Untitled6_20220402203836.png It differs in the con...

You can't compare two practically different cars. V70 p2 have different engine management,catalytic converters,sensors....and much more. Plus....when engine runs on LPG....it runs a bit hotter than engine on petrol. That said....temperature in combustion chamber is higher when engine runs on LPG. V...
