Rx8 Greddy Turbo from brazil - 255.5whp with 5psi
#27
the hp difference is running at about 35hp (at least on my car)
the dyno does this calculation based on the "weight" of the transmition during the "come back" of the rpm, this i done when you release the gear that you are on after acelerating on to 9500rpm down to 1000rpm
... i think my explanation sucked .... (i am a portuguese speaker:D) if any one care to do it better please help....

the unichip is a 32bit computer that runs with a lot of possible add ons...
the one on the right is to 'see' the pressure that i am getting and pass it on to the main unit to control the extra injector.
the other one is to control the solenoid.... it comunicates with the main unit too... of course

Still very impressive tho.

this is the link for a race group down here in brazil
subscribe to it and ask around for people that were there at the time....
(have to speak portuguese tho

ahhh
there is a CBA (confederacao brasileira de automobilismo = brazilian automotive confederation) director on the group... ask him
also check his credentials on www.cba.org.br
(i am also a member... not givin you my name tho)

last one on this subject....
i am trying to get help for my matters and give help, if i can, to any one who asks...
no one here pays my bills ... so no one should be impressed by impressive numbers
if any one is interested in replicate my experiments they can do so with the info that is posted here
this is my contribution.

This could turn out to be good way to go, and looks like it has worked on your car, but the emanage works great on some rx8's also. In general this will not work on many rx8's for the same reason that the emanage doesn't, the ecu adapts to any change you try to make. For a turbo you run an A/F of about 11.5:1, which is far richer than the stock ecu likes, therefor it decreases the fuel output to the stock injectors. If you add more, whichever way that might be, it will just pull more. Now there is a limit to how much it can pull, but if it reaches that limit it will throw a cel for LTFT out of limits. I would watch your A/F carefully as it will take a few hundred miles for the ecu to completely adapt. You really need to get the stock ecu out of control to properly tune the car.

i used a laptop to program the unichip and to colect data coming from the car, done with hymee's scanalizer (great tool!!!)

I will give you the Mini Cooper as an example; Mini is on REV 42 of the factory ECU meaning that they have re-flashed the factory ECU 42 times since the release of the Mini and we have not had to change the Unichip calibration one time. Even if the Unichip is installed on the Vehicle when they re-flash the stock ECU it will not effect the Unichip or its calibration.

you are right on zoom44!!!!
but since unichip is so independent, it is a bit harder to clean out the map....
the scanalizer has been a very good tool to help me solve my map.
i recomend it to any one who wants to do a serious tuning
it was acctualy scanalizer's data that made us go back in the tunning to more safe numbers and smother, less powerful, power curve.
right now i am trying to trim, what i think to be the very end, of small back fires, during extreemely heavy use. i know that the source of it is extra gas, so my engine is unharmed.
got to be very careful pulling fuel form it douh
if unichip america wants the data that we produced over here, we will be more than happy sending it.
solenoid, maps, injector specifications... basicaly...

I could be mistaken but I believe the unichip has full control over the single new injector. It has no control over the stock injectors. So while it is true that the stock ecu can't pull fuel from the new injector, it will pull it from the 6 stock injectors to compensate and get the O2 sensors back to 14 or so A/F Which will still cause the same problems. Unless I'm wrong and the Unichip is in fact a full stand alone ecu that controls the 6 factory injectors in addition to the added injector. I hope I'm wrong of course, and this fixes the Greddy issues, I would love to have a cheaper solution than the interceptor.

i can oly tell you what Joe Pucciarelli the National Sales Manage for Unichip in the US told me. that the unichip has full control over Fuel and Timing and the stock PCM has none. I can check with Pineapple Racing to see what they say since they are dealers. and soemone ask corksport too . they have some history with it on the RX8.

as far as i know the unichip solution can be a stand alone OR a piggy back.
how ever due to the complexity of implementing stand alone, we dicided to go for the piggy back.
my unit controls the extra injector, and the boost.
so far the ONLY ecu error that i EVER got was related to o2 sensor. but i can see your point. what might be happening then is that i am putting in what ever the original ecu takes out :D.... and from that i am not getting any erros nor i am having dificulties on the power curve, it is as good as it gets.
as far as the o2 sensor errors, i still have a lot to trim there....there are times the the o2 sensor goes out of resolution because it is soo rich. this is on purpose exclusively to protect the engine.
one extra trim that i had to make was to move the rpm cut down to 9000... that was done basicaly to protect the turbo

if you take a look at the le mans series you will see the mazda team explaining that they run realy realy rich....
and man look at the flames ... beautifuly huge back fires...
