Help with fuel controller decision

[ttsupra97]

Hi all,

 

Need some help making a decision on what fuel controller to go with (i have the 550cc injectors and us turbos now on my jap spec and am running 10:1 a/f). Choices are: a) Greddy emanage (piggyback, around $900 AUS including tuning software etc), or b) Haltech ECU (piggybacked with main ECU, but taking complete control of fuel and ignition timing, around $1700 AUS).

 

I don't fully trust a piggyback fuel controller, but I DO trust the main ECU to retard timing etc in case anything goes wobbly. Installing the Haltech will of course be a lot more hassle though (plus I need to pay $$$ for a tuner to tune it).

 

What are people's experiences with piggyback interceptors? Anyone had one on the street with a WB O2 sensor to see what the real deal is with those things??

 

Cheers,

Tony.
