So true...

As aaron says it's a complete package.Supposed to give 150kw atw and dyno proven.Also in regard to reflashes and piggy back ECUs what else is available?I've done a bit of research and there doesn't seem to be anything out there that is 100% compatible.BTW my car is an 06 man.

I mean if the mugen stuff only for show,well it won't get good numbers in anyways .
About the hondata results of fujitsubo exhaust, I won't be taking that as a review as few of these forum members took it to dyno dynamics producing 118kw -120 kw atw depend on the wheels size and weight, my self use FGK catback and comptech airbox get 119.8 kw atw at dyno dynamics at RE custom. As you might aware Dyno dynamics reads 15% lower than dynapack dyno so I might not taking it as reference what hondata produced in dyno graph, I run 1/4 mile a year ago with FGk cat and comptech air box got 15.4 sec with 19 " and wheels hops on start at calder park

I'm not trying to create confusion whatsoever what I'm saying is dyno doesn't prove anything is just a reference since if you ask many tuners they would say there are ways to make the results higher or lower than the actual results if they want. What I'm trying to say is, Jtune is not the only good products out there for euro, there are many good products out there which also provided same features that my opinion since I also view it from pricing and uncertainty release time.

^ i think this is something to keep in mind... we shouldn't be comparing results across dynos and especially not different mods on different dynos. All we can do is looks at the before and after... it's the difference the Jtune products make to a base figure - the peak number is hard to gauge

Yeah, we can't compare readings from different dynos, hence I quoted the other dynapack number (which we don't know if it is valid

). Do you know of anyone with a stock Euro who ran their car on the RE Custom dyno?. Would be good to compare that to your 119.8 kW (which is splendid for only I/E). Unfortunately the 1/4 mile number won't mean much without other Euros to compare to. I hope that I'll be able to run my stockish car at WSID one day.

Only other 1/4 mile I know if is an auto Euro with a K&N pod which pulled 15.5 seconds at WSID.

True, but they are the only one with a reflash that will not be circumvented by the ECU unlike piggyback solutions.

I'm more interested in the fully tuneable one that's been mentioned a couple of times *crossed fingers* if this actually came out the guys in the states would be very jealous

My bad.

probably better just compare it with same dyno as reference.
I had dynod mine once using XTC dynolog which also have been using by autosalon, I pulled 124kw-126 kw atw with air filter and cat back mods and my friend pulley 109-112kw atw if I'm not mistaken and his car is stock. The same mods I dynod at dyno dynamics pulled best of 119.8 kw and it is on cold weather. True 1/4 mile also affect individuals skills, but it was my first time and I even can't get the launch properly since it was wheels hops so with 15,4 sec best time with those mods, I was very happy especially it was with 19"

Probably since the only after market ecu tuning around is hondata reflash for now that have shown the results. Actually Microtech could be used in euro with affordable price but I'm not sure what might be the results. Have you consider using EFI euro ecu, it is comparable with motec in term of the features and might surpass it in term of value and it will be tuned by professionals (competition system)
