    Paul.
    Did you check out the stage 2 version?  It is fully adjustable via
    PDA and
    their software.

    No I did not but that is interesting. I think Perry might be interested
    in that. Can they lean it in an easy manner?

Aren't there multiple generations of factory ECU's?  I'd guess that
different years might have different behaviors.  Especially the gen3 cars..

If my computer had a limp home mode, I'd test it on the ground at least
once..  Figure out a way to reliably cause it - disconnect a sensor, add
a switch, whatever.  Run up to 2000RPM, turn it on and see how it does.
Cool, reset, and increase the power setting for the test point.  Keep
doing that until you are at essentially cruise power.  Assuming that
running the experiments at lower power settings doesn't cause anything
seriously bad to happen..

Is limp-home reset on power-cycling the ECU?


Regards,

Matt-

The 2nd gen is most common and probably by far the cheapest to be had in junkyards
or on ebay. It will work on any generation engine.

It is kind of easy to simulate a 2nd gen mass air flow sensor as all it is
is a spring loaded trap door connected to a pot. One could hook a large pot
in parallel and try twisting it if one suspected the mass air flow sensor
failed. In other words all it does is a supply a zero to 5 volt signal
to the ECU. Same goes for the throttle position sensor.
