yea hes right about the ecu being programmed for specific things.
u can get a chip on ebay that will do the universal thing, install it yourself for like $40 tops.

if u have specific mods and want to go to hondata that is the best way. the JUN ecu is probably optimized for different stages of JUN cams.

also dont believe everything you read...
half the shit on ebay is "JDM" until you get it in the mail and its crap.
JUN is a big name, but without a JUN head package and cams you arent getting what you should out of it. you'll probably pop a retainer above 8500 rpm also. so again a higher revlimit doesnt mean shit unless you have the internals to back it up, mainly springs/retainers, and of course stock cams dont perform well above 7000 ish. stock h22 cams are designed for midrange.

That's right the JUN ecu is has an astonomical rev limit which would kill normal Ludes. Also JUN only makes one cam stage for the H22 and it is equivalent to most stage 3's. The compensations most chipped ecu's usually make are advance timing and rich fuel maps.

Default Jdm stage 3 chip modification

Was wondering if you could point me in the right direction on how to either modify the chip myself or tell me who or how to go about getting it modified to remove the governor

I thought the speed limiter was 125 for the JDM P13, but I could be wrong.
