ACES FUEL INJECTION FAQs

A: Our system is built with a much more robust chip/processor, which utilizes Aces’ 32-bit architecture. This technology allows the Aces ECU to process information and make changes to the calibration quicker than any other EFI system available. Additionally, the ECU is mounted externally from the throttle body so that it does not experience the harmful engine heat and vibration that plague other systems.
A: For Timing Control with the Killshot, you will need one of the following configurations in your ignition system:
1.) A magnetic distributor and the Aces AC2008 coil.
2.) A magnetic distributor and a CDI box.
3.) A hall effects distributor and a CDI box.
A: Out of the box, the Killshot’s self-tuning functionality is designed to work with stock to mild camshafts. The Killshot can be run with a race-style camshaft but will require Aces’ Advanced Tuning software and extensive tuning knowledge to achieve the desired idle quality.
A: You would need a return-style fuel system suitable for EFI applications. Your electric fuel pump should be capable of at least 255 LPH and regulated at 42-48 PSI. Aces is developing its Master Kit, a complete fuel system that will be available soon.
A: It is nearly impossible to establish how much clearance there will be without physically measuring for clearance (due to engine placement, any aftermarket components, and air filters). But the Aces throttle bodies measure approximately 3-5/16-inches from base plate to air cleaner mounting surface.
A: Currently, the Killshot features a basic timing retard for nitrous oxide applications, but it does not have nitrous control capabilities. The Killshot was designed to be compatible with power adders, but much of the functionality is not yet unlocked in the tuning software. Aces engineers have yet to finalize the testing for boost and nitrous applications.
A: The Killshot has four sensors that are inside the throttle body: TPS (Throttle Position Sensor), IAT (Intake Air Temperature), IAC (Idle Air Control Valve), and MAP (Manifold air pressure), as well as two external sensors, Wideband O2 and Coolant Temp.
A: We currently do not recommend the use of big cap HEI distributors with our EFI systems. This is because HEI systems produce very “dirty” electrical signals that back feed to the ECU. The unit will work well with most stock distributors as long as they are coil negative, and of course will work with any of our distributors on our site.
A: Yes, the current Killshot system will work for single throttle body marine applications. The only change is O2 sensor placement in the header collector.
A: The Gambler Series distributor is designed to work with the Wildcard EFI.
A. We do not currently recommend our products be used with single-cylinder engines.
A: If you're interested in a sponsorship, please email us at customerservice@acesefi.com and include pictures of your build, the nature of the request, and any applicable advertising or promotion that you might be able to do for Aces.
A: It is mostly plug-and-play with a few unterminated connections.
