Help....!!!
 

Today i remove my 8 catalystic converter replace it with normal mid pipes with no cat converter but the sensor still inplace, i think i can get more HP out of it well im wrong an hour ago i run my 8 0-100 Km/h drag and my time drop 2 sec from 5 to 7 sec and below 6000rpm the responce also drop, after that i install "lamda folder" and the check engine light turn on even so i scan it dont work, remove battery for 3 menit so it can reboot also dont work and still power is lost.
i runs out off ideas, i hope my fellow 8 lovers can help me out. thanks...
"lamda folder" = device for manipulating ecu so it still think the co level is right, i install it after the cat converter sensor

Why did you bother re-installing the sensor with no converter?

:confused: :confused: :confused:

I re-installed my sensor with no cat because I needed it to plug the hole. Probably the same with speedaholic, here. He should also realize that the CEL is passive.

Lamda folder no workee.....
 

Sounds like you connected the "lamda folder" (O2 fooler) wrong, upsetting the ECU.

Check you have the two right wires, sensor and sensor ground, not the heater power & ground wires.

any suggestion..??

hope u no drive in my state.

Ignore the light or put your cat back on... Those are your choices it seems.

In Indonesia is legal for a car without Cat converter, so what the hell as along it gives me more power.
and I intend to fix that engine light problem then if next saturday the dyno said I lossing WHP I will put back the CAT.
Thanks.

speedholic,
u sure that ur 8 cant run 0-100kmh in 5 sec? :rolleyes: and which old airfield? As i know there is only 1 PRJ

!!!!
 

Oooohhh...!! you've been to PRJ Stasis1? nice long open road wright!
where exactly do you live?? except between countries!
My 8 clocked 5.6 sec exactly in the verricom device!!
I got 220 WHP in butt dyno, that before I removed the CAT!!
and I got good news, Charles R. Hill says that engine light on because CAT removed is not a problem and not lowered WHP!! I can wait to see the dyno result! "all finger crossed"
Thanks to all of you, you guys have been much helpful to me!!
Thanks a lot

:)) ;))) Rx-8 Rules....!!!
 

One more thing!!
Guess what??
I smoked Nissan 350Z this day !!
I'm so Happy this day, cause I hate 350z a lot!! many people said that 350z faster than RX-8, well they are wrong! I proved.
I love RX-8 so much, even I have to chose my 8 or my girlfriend! I chose my 8. ha..ha..ha...!!!
Hat off to MAZDA, thanks for building this fantastic machine!!

i assuming that you smoke a Stock 350Z :), but well done :)

What exhaust did you put on your 8? we are hoping to get Fujitsubo on.

Can you give me the detail of your Headers? Where you make it in Indo.

Cheers

Can we combine these threads..?

I want to see how this turns out..

!!!
 

Yes, stock 350Z but it still feels good!!
my exhaust is RB, and I make my header in "KARYA JAYA" muffler shop located in Jl. Palmerah ( direction : if you came from MPR building you turn left at the traffic light, after you turn left it placed 20 m in the left )
ypwpat I noticed that you have an 8 in Indonesia, maybe next time you in town we can meet up!!

sure no problem, Where about do you live? We live in JKT-Utara in Sunter. So far the only mod we have in the car is Rotary Extream Intake :P You happy with the Headers Quality Built? How much in Rp if i may know. Where in Indo got the Unichip dealer? and How much?

THanks

!!
 

Hey...are you Indonesian guy?? I lived at Jl. Gunawarman or Jl. Tebet Raya No.52 Jak-Sel!!
I'm not very happy with my header cause my mechanic said that it has poor quality steel and I intend to change it if I got spare money, until then I stick to what i've got after all maybe it's better than stock it have polished inside pipes so is very smooth!!
You've got to go to Sigma Speed !! the owner ( Soleh ) and his son (Boy) are very good mechanic " best in Indonesia"!! Unichip cost me abaut Rp. 3.500.000.- that priced included tuning and dyno testing!!
I intend to go there this saturday maybe you can come along!!

well it would be great but i'm still at Melbourne , but i'm going back soon.
