When you get a chipped ECU will you see a difference in performance? Would it rev up a little faster or you won't really notice a difference?

 

rev will be the same, but it will rev up higher. It will make a difference depending on what ecu it is. Do no chip your ECU go somewhere like hondata and they will make a nice improvement

 

I'm running a Skunk2 ECU (not the chipped ebay crap either) and I definitely notice a difference between my stock ecu and the Skunk2.

 

a generic spoon, mugen, skunk2, etc. chip was tuned on a certain engine with certain mods, then mass copied and sold as a one size fits all chip. which is not the case. most times, they just dump in a lot of fuel, advance the timing, remove the rev and speed limiters, and sometimes disable CEL's. avoid these if you actually want performance.

a better solution is a programmable engine management system. there are many to choose from. hondata, aem ems, uberdata, crome, etc. which one to choose depends on what capabilities you want/need and what your tuner is most familiar with.
