new ecu or piggyback?

[jakej400]

wondering if anybody can help just bought a apexi vafc 2 controller for my ek9 and am waiting to get everything remapped and tuned just wondering if theres much point in buying a hondata ecu aswell or is the apexi enough? any help would be great

Piggy-backs have alot of limitations and dont offer full control like what a Hondata does.

afc=controls fuel only.
hondata=controls fuel and ignition among other things.

It would be pointless to have both, hondata is the better option.
