Building a motor around ECM for Turbo.

[bigsteviejoe]

Knowing that skewing the MAF signal via a large MAF sensor and a piggyback, will make the ECM select more advanced timing, and reduce the margin for error that was programmed in at a given speed or load (knock retard).

The piggyback can also delay the crank signal a number of degrees programmed.

But this doesn't solve for the timing issue if it pings.

How about all the above plus lower compression?

Would dropping to 7.5 - 8.0:1 cr be enough, or make things so close that the adjustments for timing that the piggyback would have to make be minimal?

Is it possible that Buick used lower compression on their prototype and did nothing to the computer except use a large MAF, large injectors, crank delay, and skew?

Any reason why going to 7.5:1 although I'm biased to 7.8-8.0, would make the car horrible on gas or not pass emissions?
