Hi,

I created a trace of the engine CAN bus on my T4 gasoline engine with 85 kW.

The engine is a 2.5-liter 5-cylinder engine with the designation APL and the Simos 3.5 control system. The following systems are connected via CAN bus: engine control unit, mass airflow sensor, and post-catalytic converter oxygen sensor (which I only discovered today).
The speedometer and other control units (central locking, ABS, airbag, window/wiper system) are not connected to the CAN bus.

I was already able to determine the engine speed and engine temperature through the forum, as it seems to be quite similar to that of a Golf 4.

I am mainly interested in the consumption signal.

Okay, I'll throw out a few ideas:

1. Idle speed at standstill.
Code:

00,000 480      8 C0 00 2E 88 00 00 00 00


2. Drive at 30 km/h in 3rd gear.
Code:

06,648 480      8 95 00 44 CD 00 00 00 00


3. Drive at 60 km/h in 4th gear.
Code:

Time   ID     DLC Data                    Comment
59,113 280      8 49 36 D4 23 39 25 2C 1E 4rd@60kmh
59,113 288      8 07 B7 50 2F 2E 46 D4 07
59,113 480      8 95 00 90 AC 00 00 00 00


I asked T4 owners with a similar engine about their instantaneous fuel consumption during both trips. At 30 km/h, the fuel consumption is approximately 8.2 liters per 100 km, and at 60 km/h, it's around 8.9 liters per 100 km.

It would be a dream if I could be helped here. icon_biggrin.gif

Thank you very much!

Hello,

Have you already compared to see if it works the same way as described in the PDF?
