The Link G4X Storm engine management unit delivers performance that rivals any engine management system on the market. This ECU is more than capable of running sequential injection, ignition and variable valve timing on most of today's engines. The black Storm offers all of the advanced G4X ECU tuning features at an extremely competitive price. 8 x injection & ignition, 8 x analog & digital inputs.

Requires "A" & "B" Looms

Need Traction control or e-throttle? Consider the Xtreme or Fury

Direct Injection? You need the Force GDI
