Spare urq ECU I can borrow?




Does anyone have a spare MAC02B (is the 'F' interchangeable with the 'B'?)
that I can borrow for a short time to test in my car?

I suspect that the boost pressure sensor in my ECU is failing and causing
the car to idle incorrectly, cycling up and down ~200 rpms continuously.
If I connect a vacuum gauge to the ECU instead of the intake manifold
pressure and pull 15 InHG, the engine idle beautifully.  If I reduce the
pressure to ~14 InHG, the engine suddenly revs up a couple hundred rpms.
I suspect that the ECU thinks it is at the 7 InHG mark listed in the
code that changes the index into the timing table.  I know that this
pressure sensor is non-stock, and it never did seem to read correctly.
I would like to plug in a good ECU to see if it solves the problem.

Also, would the pressure sensor from another ECU (e.g. MAC07) work in
the MAC02?

Thanks,
Eric
