manufacturing tolerance. Power can vary about a certain percentage (which I forget)... but Hymee's number had fit within that range.

At least this is wht I recall from the discussions about this...

RB got 226 with a cat installed and with it tuned a little bit on the conservative side to keep cat life temperatures down. There was more left in it. It's not to say that the engine actually did what Mazda says it did but RB's number is not all that can be had from the engine. CAN the engine do 238 hp? Yes. Did it from the factory? I think we all know the answer to that.

hymee's 222hp number was after supposedly being tuned to get all they could get... somehow i believe there was more to that story but who knows

and that "best they could get" is less than racing beats number which is 225. while preserving the cat. of course they raised the rev limit too. maybe hymee didnt?

these are both sae corrected engine dynos performed by very experienced operators. they are for all intents and purposes the same . the difference is in the tune.

If you look at where the power peak is, that shouldn't really matter.

So far the best I've seen non ported was 212WHP with a intake, stock manifold, ECU tune and race exhaust. Thats ~249 FW HP assuming a 15% drivetrain loss which seems to be the average.

its a safe bet that you can hit the low 200's with a streetable car, much past that is going to require some internal work.

what cracks me up is that if you go all the way back to the begining and look at the rated power of the Euro spec 6port cars, they were rated at 228BHP. That was when the U.S. rating was suppose to "247"....hmmm, lets see its was 238, now 232, thats pretty close to 228.....funny how that works.

No body seems to notice that.

the difference from hymee's tune & RB's tune could be in the Intake ? Hymee just had an open tube if I recall .
It is only a 3 HP difference though !

well I did stir things up a bit --didn't I. Zoom , I got it--I still dont like it but i got it.
RB did good here--NOT saying they didnt--it is just Mazda -on this issue-- has not been satisfactory. I didnt buy the car for the HP-- it's a great package--I would buy another one.
It's marketing like Mazda has done that makes me appreciate people like RB and Richard Paul.(Many others out there also)
Now back on thread and sorry for the diversion.

and someone dyno the thing with a wideband O2 sensor as it seems RB isn't willing to give you even the general range they tuned to

They lean it out above 5000 rpm to try to hold it near the 13:1 area or so. The stock flash goes very rich up top hitting as rich as 10:1.

u know what all u people that are talkin **** on racing beat.............yes they may be a main source of talk throughout this forum..........but most of u people r talkin crap becuz ur ignorant......if u honestly dont believe racing beat hasnt done there homework think again, if any of u know JDM u know RE amemiya, racing beat is the equivalent over here that RE amemiya is in japan..... n in my opinion, the reason why that $300 flash is only gonna get u 15-20hp(flywheel or wheelhp) is becuz of u ****** bozos who have to ask the most retarded age old question " if i do this mod, will mazda void my warantee?" in my opinion, if ur gonna ask that before u buy somethin, sell ur car n buy a mazda 3 or better yet go buy a kia, then u can put mods on n void ur warantee.........n u people believe that racing beat is cheatin u, look around, theres not many manufacturers that make parts for our vehicles, that are ACTUALLY honest n damn close to the HP u get, n what they claim.......also in my opinion, RB should offer a emission legal flash similar to what they have now, as well as an offroad flash.........which should lean out the mix more for more power but only offer it to those who are runnin offroad mods such as midpipe, etc........who want the little more power, yet have the hookups to get around this CARB bullshit........
im gonna go drink a beer.........i feel better now

Just for your information,"......." is not the same as inserting proper sentence structure and puncutation.

Next time you decide to post, just post "......."

You'll get across exactly the same amout of information, but you'll look a fair amount smarter.

bu tteam thats one of those "run down" european calculation things on a chasis dyno not and actual engine dyno. cant give any credence to that number


but thats not what i came to talk about- finally i get to say this

Ive been running this flash for like 2 months now it seems and its a blast

the extra power is fun, reving until the tach hits 10(no it is not accurate) or just slightlky before that and the fuel cut is just great! hitting 70 in second when before i could only hit 62ish is fantastic. its a really nice improvement. its a bigger improvement obviously thanthe intake. the throttle feels more responsive over 4kish.

and while they say they couldnt find any real mpg improvements i seem to be getting better mileage since it was installed than before. my fill ups have netted me between 17 and 18.89 mpg in my normal running around town where i was getting 15 to 17.

absolutely a great NA mod for the price. Im sure we will eventually see some flash tunes that make more power (not caring about the CAT) but i bet they will cost more as well. anyone that is staying NA for the forseeable future but wants better performance should seriously jump on this.

Thanks zoom44, I take your word, as soon as the S flash comes here and my dealer update my car I'll be sending my (Euro!) ECU overseas for them to play with it and see if they can also enable the cruise control (for some stupid reason, the R flash disabled the cruise control on euro cars that didn't have it stock, while on previous flash it worked perfecly if you bought the cruise control wheel part from japanparts.com.)
