Are you looking for an affordable way to be able to select the amount of timing retard, thus avoiding knock and detonation? Then the Bipes Automotive ACU (Axiliary Control Unit) for 1990 - 1997 Mazda Miatas is what you're looking for.

Here are just a few of the features:

3-input timing map: RPM, airflow (boost), and air temperature.
Retards up to 20 degrees of timing.
User programmable.
Easy to program.
Self-contained - no PC, keypad, or other additional device required to program.
Integrated diagnostic display.
Precision tachometer display mode which can be configured to display any one of four functions via switches at the back of the ACU.
Software upgradeable by replacing a chip.
Best value (most features, low cost).

Normally Aspirated:

Probably the easiest and most inexpensive power modification to the Miata engine is to advance the base timing. This technique is well known and documented. A problem can arise if you advance the timing more than a few degrees: detonation. The ACU allows you to enjoy the power gains that advanced timing offers while protecting your engine from detonation or knock.

Turbocharged or Supercharged:

If you followed supercharger installation instructions and set the base ignition timing back, you helped protect your engine from detonation but you robbed it of power. Changing the base timing affects timing under all conditions, not just the conditions at which your engine is susceptible to knock. The ACU retards timing only when needed.

Nitrous Oxide:

To protect your engine, you may need to retard timing when you switch on your nitrous oxide. The ACU can be configured to automatically add a user-selectable amount of retard when the nitrous is engaged.
