    i still think your gonna be better off with a serial INPA interface and the 20 pin adaptor and ADS mode INPA, your guarenteed then to connect to at least the engine DME on both of your cars..

    Are you running a lambda emulator?

    All 328's or the 1995's?

    I could connect to my 1998 E36 328 using my vagcom lead.

    My problem is I have a memory like a sieve!

    That's the trick, ODB2 is a standard. Earlier 328s use the same ECU series as the later ones, ok the late ones are flash and the earlier are EEPROM or burnt.

    So because the earler ones use the same series of ECU, where the hardware can be ODB2 people say things like "they are ODB2 but with the OBD2 stuff turned off" which does, of course, mean it's not OBD2 as the one thing you have to do to be ODB2 is communicate in a certain way, not be a specific hardware.

    I would have to check to see, but yours may well have been OBD2, don't kep up with the model year evolutions lol

    Lol, well bits of it follows the obd2 standard. The E36 got a facelift around that time as well. Even that was staggered, talk about confusing.

    You are right it was the Siemens ECU that was making me doubt myself. My gut feeling is to forget it on a pre 1996 car. It's more clear cut on the other E36's e.g the introduction of the evos or the M44 in the 318is.

    Absolutely is confusing you have "the other thread" with this in the first post

    But nothing before 1997 on the "tested list"

    And things like this........

    Which is contradictory too

    Not opposed to buying one of those £70 intefaces if I must

    your making this way too complicated for yaself..your early E36 is an ADS car you need to talk to your car in ADS mode in INPA,USB interfaces "DO NOT" work in ADS mode..

    if you want to talk to some of the modules on your car like the engine DME etc you need a serial interface kit like the one shown in this thread and the basic ADS mode only INPA software..

    if you want to talk to everything on your car you need an ADS switchbox like the one shown in this thread and the basic ADS mode only INPA software..

    thats the way i see it....

    Actually I'm asking specific questions and people just repeat the same stuff making it complicated.

    All the recent questions are about identifying the how to buy a £6 cable to talk to the DME

    The default answers are buy ADS to get everything, I don't need everything.

    Personally, I'd take the chance. Worse case scenario you've lost £10. You'd probably sell it on easily enough. I've used a vagcom lead on a few later E36 328's. The main thing I couldn't talk to was the IC.

    The earliest car I've done with a vagcom lead is a 1996.
