FoxRacer600RR

wtf i have an opinion on the process of buying the AP i beleive that i should be able to buy something from a company and it atleast work....and as far as cobb tuning the AP so the engine wont blow up until i get it professionally tuned...u should hear see feel what it does with the stage 1 tune AND IF U DID U WOULD UNDERSTAND MY FRUSTRATION

***but i am listening and heading the warnings

FoxRacer600RR

yes

FoxRacer600RR

he had it for years and heavily modified it himself , thats the only reason i trust him ...he works at a shop he owns

rodjonathan

iTrader: (6)

hmmm i see ... well since you paid less for it then you can get the mm tune and it would end up being a similar price of what he offers to start with so that would be your best bet IMO

FoxRacer600RR

thank you and i will take that advice and run with it

Just what I was thinking too.


RX-7s are drastically different to tune than RX-8s. MAP based vs MAF based. Don't know the difference? Go research.


You bought a COBB expecting a generic off-the-shelf-tune-designed-to-work-on-'any'-RX-8-without-causing-a-liability-issue-for-COBB-by-blowing-engines to work perfectly the first time. Shame on you. They won't get it better than the Mazda factory tune. Point blank TRUTH, not opinion.

Remember, the COBB is a TOOL, not a SOLUTION.

If you want to get full use out of the TOOL, you have to get a tune very specific to your 8. Every 8 is different, and they are very touchy about tiny adjustments in the maps. A tune good for 1 8 is usually terrible for just about any other 8. And to get a tune, you either have to go through MM, or find a shop that has experience in both MAF based tuning AND rotary tuning. Generally, this will mean that they are experienced in tuning the RX-8, but you might get lucky on another rare option. RX-7s are not MAF based, so the knowledge there won't carry over. Only basic rotary principles and math, but none of the details needed. Other than that, you can either learn to tune yourself or pay a shop to learn to tune your car. Your car is at risk either way, only one of them you will be without your car for a while and you will be paying alot of money as well.



And don't think I am trying to pump up the COBB. I haven't gone to a tuning tool yet, and I doubt it will be the COBB for other reasons. That doesn't mean that it isn't still an excellent tool.

I am just trying to reduce the stupidity quotient.

No no no no no! I am NOT degrading your shop guy, but you must understand this : Knowing how to tune the RX-7 does not inherently make you able to tune the RX-8

Remember the word "inherent"! If your RX-7 guy has worked on the RX-8 before, and produced good results, then by all means. Otherwise, let him know to be careful. There are several horror stories from people in this forum that went to their local RX-7 guy to get the car tuned, and ended up with crap.

And regarding your Stage 1 issue - a lot of people say the Stage 1 is the same as stock, or shittier. Cobb really didn't know what they were doing when they made that map.

Lol , you know every time i get on here somebody is arguing with somebody ,....or with me but i always end up signing off feeling like i got a good answer...thanks again guys

FoxRacer600RR

i completely understand what ur saying, i have not had to rebuild my engine yet , i run the **** out of it and it has 83000 on it.....so if he tunes it and screws it up thats just a good excuse to take a shitload of money out of the good ol' savings account and build a strong motor and (taking my lesson learned) find a well qualified shop to install and tune it

And fox, I don't hate your wheels, they LOOK great. But they're not functional, especially on a car with low torque. I have a 4-banger Mazda6 now, I popped RX8 18" 5-spoke stockers with 235/35 tires and noticed a slowdown in get-up-and-go. Stock size is 215/50 on a 17" Miata guys did physics calculations that determined for every inch in diameter you increase you need to drop 3 pounds in weight to have rotational mass stay the same. So if you get an 18" wheel of the same weight you still come out ahead.

If you want speed, the cheapest mod is to take all the audio stuff off and put stock wheels back on.

After that, a custom tune- just like the guys with a MS6 or MS3 have to do. They have more base maps because of their community and ECU, but you're in the same boat.

If that's the case, no problem! You understand the risks, and have backup plans with it. If your tuner is good, or willing to use your motor to learn, that's even better.

Just as long as you understand what RWWIP said - the Accessport is a tool. How you use the tool is up to you. This particular tool is excellent - for now, it is the best tool you can get for tuning the RX-8 (unless you have extenuating circumstances). The AP does NOT suck, the Cobb maps suck

You need to view the Cobb AP as tool. It requires input which you have not provided any.

FoxRacer600RR

agreed, disregard the tittle, COBB acessport (maps!) SUCKS

The maps MUST largely be ineffective due to federal regulations. When you hire the proper person to tune your engine for "off-road/track-only" use, that is when you will glean the best performance from your RX-8.

Since MazdaManiac has provided something around 800 tunes/maps I am pretty sure you won't find anyone who has as much experience with tuning such a wide array of RX-8s around the country and around the world.

dynamho

Not sure if this was mentioned, but you sport an AEM CAI. I don't think Cobb's stock tuning works with it.

My recommendation is to either tune for your CAI or take it off when using your Cobb.

ronx8

i don't have a cobb ap, but I could've told you the stock maps blow.
shoulda done research and got it from MM

What is a Mazda Maniac?

Red Devil

Why don't you just download the Race software and do it yourself? Tuning the Accessport is pretty easy once you get the hang of it. And if your buddy can tune RX-7s competently then tuning a naturally aspirated Renesis should be no big deal.

freaklinkmusic

you can do tuning out of the box if you have experience and LEARN just like you did everything else. Dont play around with engine tuning until you learn, or you'll be selling those wheels for a new engine.

Here's a shot at what might be causing your issue. From the mods listed in your sig, you have the following: On Cobb's forum as well as on here, I've seen it stated numerous times that the stage 1 map should only be used on cars with the stock intake (panel filter in stock airbox is ok) and a catback exhaust.

Running an aftermarket intake (like the AEM/Mazdaspeed) requires a custom tune. Cobb states this clearly in their Map Notes.
