Calculateur "VEMS Motronic55" moteur R5 2.2L 20VT Audi 80/200/Urquattro Avant/Coupé/Limousine Quattro S2 (89-92, 3B/RR)

VEMS V3.x ECU with Motronic55 connector and internal MAP sensor,

moteur R5 2.2L 20V Turbo pour Audi 80/200/Urquattro

Avant/Coupé/Limousine Quattro S2 (89-92, 3B/RR).

BEFORE purchasing (claimed new or secondhand) VEMS motronic55 controller from third

party, negotiate the serialnumber, and write the serialnumber (VemsTune displays serialnr on the

statusline when connected) in the contract (and insist on void contract if serialnr was specified

wrong). If serialnr: 2595, 2731, 2934, 2904, 3321, Contact us.

The Audi AAN (same pinout as the ABY/ADU) and the Audi 3B/RR were the first applications

(note that the 3B/RR has different pinout with only 1 ignition channel). These use special

"Auditrigger" 3 sensor trigger system with the 135 tooth flywheel teeth VR, crankhome-VR and

cam-HALL sensor.

The Audi factory MAT-sensor (manifold air temperature) is PTC type, so 430 Ohm pullup resistor is

used for better precision. If you replace MAT-sensor with an NTC type sensor, write "weak (2k7)

MAT pullup for NTC MAT" in the order note. (Use this exact wording, please).

By default, the JPT55/pin5 (carbon-canister-valve control pin) is not connected. However, at order

time the following order comment can be useful for AAN/ADU/ABY : "JPT55/pin5 = IGBT

and +1 analog input on SSC6".

When installing the controller, Click here for steps REALLY.

COME BACK TO THIS PAGE WHEN YOU RECEIVE YOUR DEVICE. By following the instructions you

will have an editable page with some DVM measurements (Ohm and Voltages), saved vemslog of

startup attempts. Following the instructions is required for support (if a support request includes

the page URL, support will help, otherwise not until one follows the instructions - some useful data

is really required so support can start review and help - often will request more specific

measurements).

For Audis, VemsTune/QuickStartAudi procedure helps to get an initial starting config (Note : "with

cam-HALL" inverter is standard. Normally similar config is uploaded in factory after hardware

testing if not requested otherwise in the order note).

Bosch made many motronic ECU-s with this connector, but different (incompatible !) pinout for

different carmakers.

Wideband controller (inside ECU) and connector is included.

LSU 4.2/4.9 (wideband O2) sensor is optional, but highly recommended.

Specify the engine code in the order note. Also specify if NTC type (eg. Audi 1.8T) MAT-sensor is

used in an Audi (instead of the factory PTC type sensor).
