[s-cars] Code 2142 with new MRC chips

[chris chambers]

Tim,

What level of tune do you have in these chips?
I have a set of MRC's RS2 tune that I can loan you for test purposes.

Of course that only works if you are comfortable with opening your ECU.

Oh and one thought, if you installed your own chips you might try
making sure the chips are firmly seated in the sockets and there aren't
any bad solder joints before buying a knock sensor.

Let me know
Chris
