Thank you Jim. I appreciate you responding.

Your answer brings up another set questions!

Since the "intake software" version was to deal with the self-protection function of the DME, can the "intake software" be used successfully without an aftermarket intake, i.e. stock OE intake? If so, why offer two versions? If not, why not?

Bob ///M3

: So I'll answer..

: First off, anything anyone else is telling you about my "normal" software working fine with
: an intake is BS. The whole reason I developed
: the "intake software" is to deal with a self-
: protection function in the DME in your car.

: Now... what's different between the Intake
: and Normal versions.. JUST this function,
: which is modified to now work with the Intake.

: What happens..

: Actually it's simple.. your intake allows more
: air in that the stock one.. ANY intake does.

: Under certain circumstances (detailed below)
: the car will PASS above a threshold WITH an
: intake, that it would not have WITHOUT the
: intake. When it does this, the DME temporarily
: increases the fuel mixture (rich) anywhere from
: about 12% to 44%. This causes the car to bog
: and is usually detected by the DME as a "misfire"

: The conditions are:

: 1) High ambient air temp
: 2) High coolant temp
: 3) High air mass flow
: 4) Vehicle entering knock retard by some amount.

: When all these factors collide, if the air mass
: is just high enough and the God's are frowining,
: the DME enters Catalyst Protection and FWOOOSH.

: It dumps fuel to "cool down the cat"

: It all has to do with a catalyst temperature model
: inside the DME that never took into effect that
: someone might change the intake.
