please correct me if I have this wrong, but all MPi's from 96 onwards have OBD2 ports??

if they do, do they monitor speed - ie how fast you are actually going - and if this is the case, how is that information / data collected?


I need to find a way to integrate OBD2 to a non mpi engine, purely to gather info / data for:

# Vehicle Speed
# RPM
# Fuel Consumption
# Engine Coolant Temp
# Fuel Pressure
# Calculated Engine Load
# Throttle Position
# Intake Manifold Pressure
# Air Intake Temp
# Timing Advance
# Mass Air Flow
# Fuel Level
# Barometric Pressure
# EVAP System Vapor Pressure
# Fuel Trim

this is the weird bit - I dont want the ecu to actually run the engine - just monitor the above so i can create a digital dashboard of a fairly unique nature.
its a long shot but worth a go.

cheers

have you tried a performance meter....

such as www.race-technology.com AX22 or similar as these will down load to a pc

Ps. Do you know how to get the links to work..... as it appears to be a little dead ??

I didn't think any Mems was OBD compliant? Simple enough though if it hasn't got an electronic speedo/sensor it can't do speed obd or not.

And as I sell MPI speedo cables that appears to conclude that speed will not be possible via an MPI ECU...................

On the other hand a performance meter uses an accelerometer or a GPS sensor, can you perform electronic "wizardry" and couple up an accelerometer to a Laptop or some other computer type device.....

good stuff thankyou martin, i'll call them tomorrow to see if their kit will give me the signals i need, and just how their PC interface works. clever stuff though.

on the atatched PDF is does begin to suggest that the majority of later lucas ecu's are OBDII compliant, but I thought that meant it had to have speed signals?? to meet the requirements of OBDII compatability????

Not sure about the OBDII linking with Speed sensor, its a few years since I have seen the regs on OBDII, however I do know that the performance meter can use a USB cable... there are books about to explain how to get it to link up and read etc..... look on the Bay...

Not something I really know about but it could be possible that the MPI ecu is compatible with a speed transducer but just doesn't use one on a Mini? It could be a major can of worms fitting one and sorting the firmware though.

The MPi is NOT!!!! OBDII complient. It may have the same 16way socket, but it is NOT!!! OBDII.

I guess that is why Techbooks go for so much Money

OBDII is from about 2001 onwards, the 16pin socket has been used for years since about 1995, VW's & Fords used them i think there are some other manufacturers as well.

So do you just want to use the ECU to moniter the outputs? and does it have to be OBDII?
