  1. #1

    Default Fs: Bipes Acu

    Bipes ACU with v1.5 chip. Gently used for about 1 year. In original box with original instruction manual. $185. OBO.
    What's left of a '96 Miata with stock clutch.
    My car exceeds my driving ability. That's the only possible explanation.

    The BIPES ACU is just for timing control. You would still need something else to control the fuel.

    Gonna put ITBs into the Element?

    I sometime have trouble keeping up. I was thinking ITB - Improved Touring B. But, I think I've got it now, individual throttle bodys.
    On the track, I am fearless.
    If you were as slow as me, you wouldn't be afraid either.

    Yes, the Bipes ACU is a nifty little black box that is wired in between the engine and the stock ecu. It enables you to pull (reduce ) the timing advance based on rpm, temperature, etc. In my naturally aspirated installation, I set my static timing on the engine at 18-20 degrees and then used the Bipes to reduce the advance at the upper rpm ranges. This allowed increase in low-end torque without the fear of high-end detonation. I think the FI boys use it in a similar manner, but since I don't have FI knowledge, I'll let sombody else explain that.
