hey people who understand tuning far more than i do....
alright so i have tried to research tuning and such but i just dont have enough time to really go in depth with it. I'm starting to finish up modifications to my 8 and im thinking maybe the last thing i'll do is the cobb AP. As of now i have an AEM intake, RB midpipe and catback as well as BHR ignition and im considering a new lightweight flywheel and underdrive pulley system. At this point im guessing i've added 20-25 hp with all my current mods (if i'm lucky that is) and im wondering how much more i could get with the addition of an AP...any and all info is much appreciated...thanks guys!

You would be lucky if you added 10whp with that list - AP might get you another 10.

man people sure get upity about trying to get answers around here...i did search through older posts and like i said in the title this stuff is over my head so nothing was helping me figure it out...it's tough to get a straight answer out of 57 different pages of back and forth conversations in different posts...i dont have enough time to sit and read all of them and figure out how to tune a rotary engine, otherwise i would. sorry for the new thread post, i hope i havent inconvenienced you.
In the past, MazdaManiac has put on training seminars on how to tune. You may check with him on if/when the next one will be. You could also look up Kane's PPO software that will do the tuning for you after you plug in some numbers.

hey thanks for the info! both suggestions sound like they'd be really helpful.
the search feature on this forum is not very helpful. Googleing the question first helps me get to the best thread pertainig to my question. Then you have to read through many pages to get the info you need.
Maybe their needs to be more stickies?
It's called learning. Sorry that some people find it such a difficult concept. How do you think the other people who have the answers got them? Now they should write a thesis explaining it all on your behalf and then make it a Sticky that nobody ever bother to looks at? If we could all be spoon fed knowledge without any effort then life would be grand. Unfortunately it just doesn't happen that way, or rather perhaps it's what separates those who have it and those who don't.
You don't understand enough to know any better. Without going on the inflated ego defensive, can you grasp what this means? There are people here who will tell you everything you want to hear. They love to have an audience and show their prowess. The only problem is, the prowess generally tends to be more in their head than actual ability or understanding. Misinformation flows through any internet forum like the muddy waters of the flooded Mississippi river. Often even the supposed experts are wrong. Knowledge isn't about what you are told. It's a path that takes a lot of effort to find and stay on.
Your reply is a perfect example of how being told knowledge rarely works against only being accepting of what you want to hear. So I'm sorry that you thought I was getting uppity. You apparently didn't realize that you were being offered a choice between the red pill and the blue pill ... back to the false world with you then ...

just remember that the voluminous pages of crap you don't want to read are a result of threads just like this ...
listen man i dont have time to read all this stuff about tuning a rotary engine. I'm currently in pre-law and have no time for much of anything but school. I dont have enough time to sift through irrelevant information. I joined this site to ask questions and get answers and until lately, it's been extremely helpful. Unlike you, i cant devote most of my time to understanding the needy rotary engine. Many other people on here also just want a simple answer. If it bothers you to give straight answers then dont respond to my question and please dont give me any of your guff because frankly I dont need it. This is supposed to be an open, friendly and helpful forum but you seem to want to make it into a text book with no index or glossary. There's nothing wrong with a quick easy answer when it comes to something as unimportant as cars.

hey man, don't get upset..please understand, there ppl have been in forum for awhile, and they always do searching, and sometimes we all just get tired of answering the same questions that have been answered and discussed...
anyway, those upgrades that you do will not net you alot of WHP...don't know about what AP can produce in WHP when in stock, but you just change the sound of the car and better ignition system. you should know that it is hard to get HP out of NA engine,,especially RX8..
if you are looking for better HP, change the car with higher WHP..if you wanna enjoy the car, then you should change whatever to make it reliable and get the upgrades for the driving wise(suspension wise). thats all..

i understand people dont want to answer the same questions but thats why they just dont answer them and let someone else do it. also thanks for the info...i understand it's hard to get hp NA but until i can afford a supercharger i still wanna get the most out of my car that i can get. suspension upgrades are iffy as my car is my daily driver and i live in nebraska and winters can get dicey. thanks again tho man.
I think you will get some insight on tuning here, but your not going to learn everything. If time is an issue, your better off having someone else do it until there's a point where you do have time. How to tune isn't something that can be summed up in a couple of paragraphs, or else there wouldn't be so many people that have created a business around performing such a service.

The shortest answer is to go ahead and get the Cobb AccessPort form MazdaManiac and let him handle the tune for you. Each car/engine is different and each one seems to respond differently to whichever mods are used on them. In any case, the right combination of mods will improve driveability, reliability, and power output. Not by much, as Mazda did a very good job in the first place, but there is a little bit of room for improvement to be made.

Like me.. thats why I bought an AP with the MMCC. I know when to leave it to the experts. LOL
Calibrate maf between .98 and 3.01v, and fuel tables at loads >.81 and rpm>2500. Bump up OMP rpm/load duty by about 5 everywhere. Change idle and fan settings. Increase throttle duty A table (like a Blitz throttle controller!) Disable a bunch of DTCs, including some that might actually warn you about a problem.

et voila! A MazdaManiac NA calibration.
What else would you expect a NA calibration to need
I've never worked on a lawn mower, but tuning carburetors is harder IME. I hear that once-upon-a-time regular people learned how to do that and they didn't need experts (or lessons.)
some pretty funny commentary from a couple of guys who can't even effectively tune a 1 cylinder lawnmower, let alone a Renesis engine
damn, i wonder what ECu that can be used for lawnmower...it's cool if we can tune it so it can do teh job faster......

it's ok man...i went through a lot with my 8, from NA, to greddy turbo, to T67 turbo, now GT35R...now i fix my car myself, and change the set up. i tuned my own car using INT-X, with t67 turbo upgraded everything. next, needs to tune with GT35R which spools little faster.. it's a tough road if you wanna have a big #s on the wheel..but if it's your DD, i think it's better for you to get Ap adn ask MM to tune it according to Upgrades that you have..and enjoy it..
but good luck with everything that you are trying to do with your car, try to think twice if you are trying to pu FI in it...
