Monsoon 2008 - OBD EOBD

Recommended Posts


I like to adjust my propane system (MPI)

Therefor I got a OBD-2 Testkit to read lamda and gas correction data from the motorcontroller

while running gas or propane

also the propane ECU is able to use OBD data for online adjustment.

The test-connector on the motor (next to the electrical motorbox) is not fitting to the OBD-2 connector

is there another connector or any adapter?

Anyone has tried a standard automotive code reader on a 2008 Motor would work ?

I am still have queries on the service connector

The 2008 Monsoon schould have a MEFI 5 controller and a CAN data system.

The connector type is different from a OBD-2

I would like to ask aboud the pinout of the Indmar connector

The pinout for the 16 pin J1962 OBD2 connector are as shown here:


May be anyone can help me to lokate the pinout on the Indmar connector.

I will add a pic of the Indmar connector later on.

I need it to use the signal for a online adjustment of my propane ECU

Thanks a lot for any help.

Thanks for help

Finally I got all detail data direct from Indmar - very good service!

The storry behind:

I converted my 2008 Monsoon with a propane system.

I did this because in Europe we pay around $ 8 / gal for gas and propane is on the half price.

The propane system is a MPI whish is fully electrical controlled (ECU).

Basically the ECU of the propane system using the signals of the gas ignition for timing the propane after adjustment procedure.

For additionally 'online adjustment' the propane ECU is able to use data of the CAN bus.
