i think we are all looking to find 40 hp from a tuner. we all will take whatever time nesessary to learn to tune for 40 hp at the wheels...... kid get a flash. if you can put in the money get the CZ kit and get it PROFFESIONALLY tuned. do not ever mess around with your ecu or trick it if you dont know what your doing. so many thing effect everything else. you will adjust fuel ratio then will have to go back fix timing and every other setting again... and again.... and again.

 

Where did you find that info? I cant find anything about that on the RB site or in here. Any idea on how much it will cost? By the way I am new here and I want to know what "FI & N/A" mean in here. I keep seeing them all over the site but a search on them tells nothing.

 

Financially Invested and Not Available

 

Forced Induction (turbo, supercharge, nitrous)

Naturally Aspirated (not FI)

 

Did you try reading the FAQ (the one that is REQUIRED reading) before you started posting?

https://www.rx8club.com/rx-8-faq-9/faq-update-63747/

 

Check here for the RB flash: http://www.racingbeat.com/FRmazda4.htm

FI is forced induction (eg. turbocharged or supercharged)
N/A is naturally asperated

 

yea i guess the RB flash is what im looking for, but 3 more question...with the CZ kit i would have to worry about LIFT, so what i would have to go get it tuned over and over again? with the RB flash would i still have to worry about the LIFT? and why do they call it LIFT?

 

LIFT? I don't know why they would call it that. Maybe it gets you high.

 

I think you mean LTFT. I have no experience in tuning. MM should be able to help once you get your terms correct.

 

oh ****!...ive been misreading it the whole time, my fault. What does LTFT mean?

 

long term fuel trim

 

c&p from the web:

Fuel Trim refers to feedback adjustments to the base fuel schedule.

Short Term Fuel Trim refers to dynamic or instantaneous adjustments (i.e., during braking/accelerating).

Long Term Fuel Trim refers to much more gradual adjustments to the fuel calibration schedule than short-term trim adjustments. Long term adjustments compensate for vehicle differences and gradual changes that occur over time.

 

Add this one onto the list of possibilities -

basically Lee Bunnyz STFT (short term fuel trim) is just the a/f mixture that the computer is readin at any given time at any given second............however LTFT(long term fuel trim) is basically what the computer compenstates for, whether ur 8 is runnin good or bad(LEAN OR RICH, or ignition or mechanical problem) dependin on if u have a problem with say a bad spark plug, leakin fuel injector, intake leak etc.............bascially the computer compensates for it, so ur car will still run right but buy usin a good oscilloscope or somethin along those lines, even a scanner, will tell u ur LTFT............n based on that u will know if u have a problem.

 

so whats the point of buyig the CZ kit if the LTFT learns wats about and takes the power away? or would the i have to tune it at a higher RPM such as 6k so this LTFT doesnt learn about the CZ's tuning?

 

I don't have a CZ and know very little about tuning, but since no one has answered yet here we go. The ECU will adjust for changes the CZ makes, then the CZ will have to be tuned again. But, this is only the case in closed loop mode. In open loop mode the ECU doesn't make those changes. Open Loop Mode is when you are running WOT (Wide Open Thottle) or above a certain rpm (I think that is 4500 rpm).

 

You don't have to re-tune a CZ once you have it dialed in for your car. You have to reset the PCM periodically to compensate for the LTFT adjustments.

 

oh so you dont have to retune it, how do you reset it?

 

Remove the battery cable for a while will accomplish that quite well.

 

or get a racing beat flash and dont worry about LTFT at all i dont

 

you have the RB FLash? how is it?

 

showoff

 

Zoom44 ?

 

I think Zoom was a tester for RB on that project.
