To begin I really don't know anything about crome so I am trying to get some more information. I have read Brian and others posting that crome is the same thing when compared to Hondata. I am guessing that is ment that crome has the same tuning abilities as Hondata does. I want something that is reliable and runs/idles like stock. As for the differences, are their any, at all? Does my ECU need to be "socketed" or whatever that means? Can I datalog with crome? Better yet is there anything that Hondata does that crome does not other then making my wallet lighter? I am not sure if I want to do the tuning or if I want someone else to do the tuning. I know that in order for me to do the tuning I need a laptop, a good wideband o2 sensor and quite a bite of dyno time. I was thinking that if I get one of the engine management systems avaible, I would do it at the time when the turbo is put on. But I am also thinking that once the turbo goes on it will only need to be tuned once and thats it. That's why I don't know if I should do it or if I should have a (insert choice) dealer do it for me. And what's deal with the P28 ecu being the best or easiest to tune/work with. I have a p72 with my GSR now but am I going to need a different ECU to use Hondata/crome?
