utec+reflash > reflash?

WReXd · 09-20-2008, 02:33 PM

I keep hearing people say the utec+reflash combo is the best engine management setup ever (next to a standalone), but I've never heard anyone explain why. What can this combo do that just a reflash can't (besides SD)? And is there any reason to go SD other than maxing out the maf?

Speed density is much easier to tune than a maf based map. Reflashes tend to yeild smoother results when tuning for larger injectors. Romraider can change parameters that a utec can't (i.e. tuning for e85, idle speed, etc.) Using a utec on top of a reflash gives you the ability to switch maps on the fly, have launch control and flat foot shifting, and knocklight.

Thanks for the reply. That makes a lot of sense. Is there anything else the utec can do that will compliment a reflash?

I would put it like this. What can a reflash do to compliment the utec? You can get a utec tuned car to run just as well as reflash depending on what your mods are. You have a 207 right? A reflash can adjust the avcs and utec can't. The utec can control meth injection/nitrous with spare solenoid control. Just depends on what you have and what you're trying to do.
