Who is running GReddy E-manage Ultimate or HKS Fcon IS?

[rscott22]

Hey guys,

Was wondering who on here is running GReddy EMU or HKS IS or who has used it in the past? Just want to here some feedback on these piggy back systems I have worked with mostly 96 and newer cars so piggybacks are never the best choice being that most OBD2 cars usually overirde the tune piggyback trys to foolins into the stock ECU. Was wondering if anyone has had great progress or great problems with these Piggayback systems? I like Greddy stuff but it has always seemed to me like GReddy was the C student and HKS was the Nerd of the class always getting an A+!!! So if anyone has any exp or heard great or bad things please chime and give as much specific detailes as possible it would be much appreciated!

P.S. I know the HKS IS can only be tunned by an HKS pro dealer or someone who is lucky enough to have a key to unlock the software.....

Thanks,
Ryan J. Scott
