The use of rods in conjunction with the IIDTool or EASControl will allow for a greater range than software changes alone. The EAS ECU allows only a limited range of adjustments for safety reasons. We do think an otherwise stock suspension and stock vehicle would be at the limits of what is sensible and what is actually an improvement even in extreme circumstances. Therefore, we do not recommend the use of rods in conjunction with the IIDTool or EASControl
