The Advanced RPM Control (ARC) module helps a race car run consistent pass after pass by controlling engine rpm and driveshaft speed down to the hundredth of a second. Racers can set three different timing retard curves plus a rev limit curve, pulling timing for a split second if tire slip is detected, all programmed through MSD View software.
Specifications:
- Part Type: Engine Ignition RPM Governor
- Product Type: Modules
- Sub Category: Secondary Ignition
- Part Number: 7761
Requires a driveshaft sensor (Racepak Hall Effect Sensor PN 800-SS-MSC-5 and 8-Magnet Split Collar) plus the 4-Connector CAN-Bus Hub.
Compliance: This part is legal for sale and use on Racing Use Only Vehicles — competition vehicles that are not registered and never operated on the street. It is against the law to install this part on an Emissions Controlled Vehicle (1966-and-newer California-certified or 1968-and-newer federally certified vehicles).
FAQ
What does the ARC module (PN 7761) do?
It sets rpm limits based on slew rate (rpm acceleration) or time since launch, helping control the engine's rpm curve and driveshaft speed for consistent, maximum-traction passes.
What sensor is required?
A driveshaft sensor is required — MSD recommends the Racepak Hall Effect Sensor PN 800-SS-MSC-5 with an 8-Magnet Split Collar.
How many timing curves can be programmed?
Three different timing retard curves plus a rev limit curve can be set to control wheelspin.
Is this part legal for street use?
No. It carries MSD Emission Code 4 and is legal for Racing Use Only vehicles, not street-driven emissions-controlled vehicles.
