C++ maybe?

Awesome! :evilgrin:

BUT, is it more than is needed to just 'shift' the crank sensor input. The original embedded ECU curve is probably adequate - it just needs to shift to the left (i.e. start more advanced and keep advancing as RPMs climb...) kna' mean?

I am *assuming* the sensor is a inductive pick up sending an amp sine signal _-_-_-_ pulse.
to tell the computer when TDC is. The computer would take the signal but fire the coil/plugs x degrees before TDC.

So. How can we make an *adjustable* sine wave 'shifter' (to shift to the left/advance). Keeping advancing until the car (test mule) pings on premium gas on acceleration.

Determine that 'degree of shift' and patent and produce that unit for the masses (us! ;) ) Sell at an outrageous profit (relatively low production run - unless it can be used for all Mazda (other engines? ;) )

and pick a spiffy name too! i.e PingMaster2000 teehhee.

if it is what i think he is talking about then it only boosts between 1-5k.

It is really hard to advance phase shift a sine wave. You can retard the timing by delaying the signal, but to advance it would be difficult without a microcontroller setup like i listed before. It would take in the current RPM and advance the timing based on RPM...essentially, shift the entire incoming sine wave. I could give a better idea if I had an idea of what the signal from the crank sensor looked like exactly.
