ECU Calibration for Marine & Ramjet Engines

Description

Arizona Speed and Marine offers performance re-calibration of your Electronic Control Unit (MEFI 1, 2, 3, 4, 4A and 4B ECU)

Have you modified your stock Mercury EFI Engine with high performance exhaust, bigger cam or planning to add a supercharger, we have calibrations for most custom applications.

Ramjet 350 and Ramjet 502 engines can also be re-calibrated to correct rich running conditions, high idle, and custom engine requirements.

The ECU precisely controls all engine functions including spark, fuel, detonation control, idle speed, and rev limit. AS&M has dyno tested different engine combinations and has the knowledge of what works best. If you are planning to make any modifications or already have, the ECU re-calibration is necessary.
