Bipes ACU for sale. SOLD
Posted: Sat, 08 Jun 2013 6:22 +0000The Bipes ACU (Auxiliary Control Unit) dynamically retards the timing of your engine to protect it from detonation or knock.
The unit works on either normally aspirated or forced air (turbocharged or supercharged) eng
Normally aspirated
Probably the easiest and most inexpensive power modification to the mx5/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.
On my 1.8, I advanced the timing to 18 degrees and had the BIPES Unit set to pull the timing back to 10 at high RPMs to give me good top end and far better mid-range. Its easy to adjust and it does work. On a turbo engine you can leave your timing at 14 degrees and set the unit to pull the timing back under boost to protect the engine giving you far better response off boost and keeping the MPG up!
Turbo/Supercharged.
If you followed the Turbo/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.
ACU 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.
•Software upgradable by replacing a chip.
•Best value (most features, low cost).
Easy to install. Comes with instructions.
