Suitable piggyback for campro cps...

Can't seems to find a suitable piggyback ecu for campro cps, for E-Manage you can't tune your ignition properly and some tuner told me that he can't tune air-fuel with Unichip. I will do some research and hope to find a suitable piggyback for campro(heard that GT auto can tune ignition with E-Manage). I will update on this asap. Cheers!
