Hi Ken,

If you installed an 007 AMM into a 1990 240, the potentiometer on the 007 had no effect whatsoever on anything; i.e. the performance change you saw was coincidence. There's no electrical connection to it from the LH2.4 ECU.

The 007 will operate in the LH2.4 environment, but the adjustments are made automatically by the computer as it adapts to the new component. I drove a newly purchased 1991 for a month before noticing the seller had installed an LH2.2 (-007) AMM to get it running. It seemed a might peppier once I replaced it with the correct 016 unit, but I'm aware of the subjectivity in that perception.
