    Hello,

    I'm looking for a diagnostics set Magneti Marelli Unitest TMF 5000 for 1988 Maserati Biturbo Spyder.

    Does anybody have one for sale, please?

    Thank you

    A BiTurbo owner in France developed a more modern ignition diagnostic tool which should give you more precise information than the Marelli Unitest. It will work with any fuel injected BiTurbo with a distributor.

    You essentially replace the EPROM inside the ignition ECU with that which the developer supplies. The EPROM is a plug in module and is very easy to replace. The new EPROM has the software needed to run the diagnostic tool.
    I received the tool three days ago and I am still in the learning process but already discovered some issues in my car that need correcting.
    This is a video of the tool's display taken during engine startup and idle. The car is a 1989 Spyder 2.8L (USA version)


    Send me a PM if you are interested in contacting the developer. I have no financial interest in this product.

    I don't think it will be of much use on the 81. But that must be a typo. First FI cars were in 87.
