Stage 3 also uses the Holley Dominator, and adds Drive by Wire throttle control for the stock or aftermarket throttle bodies. This is only recommended for manual transmissions, or for cars with swapped transmissions. This kit can also control a 4L80E transmission.

Plug and play Holley ECU upgrade for the LSA engines in the 09-14 CTS-V and 12-15 ZL1.
Allows easy installation and integration of the Holley HP or Dominator ECU to these cars without hacking. Plugs directly into the LSA injector and coil harness on the back of the heads and retains stock manifold sub-harness.
Complete with 5-bar map sensor included. MAT, oil psi, fuel psi and Holley NTK wideband sensors also included.
Fully sequential, closed loop fueling. Flex fuel sensor connector and custom calibration included.
5-bar map sensor will allow safe fuel and spark control past what the stock ECM is capable of.
Simple 2-step and timing retard activation.
Just like the rest of our record setting CR-Fueler plug and play kits, the harness is fully labeled, instructions and support are included.
Custom base tunes are pre-loaded based on your setup in the ECU prior to shipping.
Note: Stage 3 with Drive by Wire control will eliminate fatory cruise control function.
