He's said the major problem is that CA requires the cats to be at operating temperature within 5 minutes of engine start...

For some reason mazda couldn't come up with a timer to give a messed up map during that time, then go back to a full map later...


Sik- If you read the last few pages, he indicates that it's almost done, and that he'll have a webpage/sponsorship here soon

Thanks for the input. Assuming that the CA 5-minute emissions is the only issue, it seems like what everyone else says...it's a no-brainer!

panda

i would like to.....i have read up to around the 15th or so page of the thread, very interesting info in there! lots of interesting stuff! is there any hints to when it will be available, i havnt had time to read all the thread yet! forgive me if this has allready been asked many times!

I baby my 8, with all city driving, I am still only getting 15~16 mpg.

if there is ANYTHING i can do to improve it, and get more than 340km a tank, I would do it.

you think that's possible with a properly reflashed ECU??

Psylence

15-16? Man, I *never* break 13mpg, and my last tank was 12.9mpg!

A fuel map that keeps correct a/f ratios will provide an increase in economy over a map that is excessively rich.

I am usually very conservative and usually would never think of modding a new car. However, I have become so caught up in the car and Canzoomers work and other Mods I think I'm going to bite. I think a good all around setup would be Canzoomers stage one with Racing Beat CIA and Racing Beat front and rear stabilizer bars. Maybe the Racing Beat exhuast if it proves worth while. I don't believe I am actually considering this, although there are probably alot of people that are on the fence that will bite when they get more used to the car and it starts to feel slower to them.

KyngNothing, you need to go work for Mazda! What a simple yet brilliant concept. A different map after the car warms up. It's so easy.

This mod could cost $1500 maybe $2000 and it would still be worth it. Think of how much money in gas you will save. What if you could go from 18 to 25 mpg average. That is alot of money in gas very quickly and the added convienience of not having to stop all the time. On top of this the car is much faster and tunable. Don't count on it being less than $500. That would be foolish on his part. People are willing to pay $500-$600+ just for an intake and catback exhaust that gives only a few horsepower but won't $1500 for something that gives better mileage and way more power?! This is a no brainer and as long as it can be easily removed for service reasons there is no reason why demand shouldn't exceed his ability to build them. When I get my 8 that will be the first thing that I do.

Andrew, I think Canzoomer said something in another thread about building the first batch of these currently, and hoping to have them shipping around Nov 12th.

Lock & Load

Definetely interested canzoomer has been very informative and thorough in his research on the rx8 .
As long as the product gets positive feedback from the forum members i am in , assuming canzoomer supplies the AUSTRALIAN market.

For those of you considering the Stage 1 from CZ, be advised the HP gains are there, but do not plan on much in mileage improvement, and you better not use 87 octane.

Mileage improvement only exists in the upper RPM range, because of leaning out the mixture to more suitable ratios.

Gord96BRG

When Mazda re-flashed the ECUs at port for the first delivery batch, the cat warm-up wasn't the issue being addressed (you don't run at full throttle during initial warm-up, do you?). The main concern is the missing hp at full throttle. The reason that Mazda changed the fuel and timing maps was that with the initial tune, emissions output regulations were being met just fine, but Mazda was concerned that the operating temperatures of the catalytic converter at full throttle, high rpm, were borderline too high for the cat to be able to last the required 100K miles. In order to run the cats cooler so that their expected longevity would be sufficient to ensure that they didn't expire too early in the vehicle life, Mazda had to richen the fuel and reduce the timing. With the last minute change, it seems that Mazda also left the mixture too rich even at part throttle operations.

That's why Mazda left HP and mileage on the table - to ensure that the cats could last 100K miles as required by the US emissions standards. Which also means that they can't easily change the maps back - but they could certainly tune the part-throttle operations for better fuel economy, it seems. Canzoomer has said that his base map should still be emissions compliant - but I'm sure he's not promising that your cat will last as long as with Mazda's fuel map.

This info was all stated by canzoomer over the course of the zillion-page thread.

yea haha that thread's a killer

RX-GR8

like war and peace but worth a read.

Genom

Actually if I remember correctly he mentions that city driving WILL see a improvement since low RPM's are running rich and he is leaning it out a bit with the unit.

regardless, if plugging that puppy in puts me over 210WHP, I will consider it money well spent :D

Count me in!!!

Thank you Gord...keep warm

Sorry, guys, I just stumbled upon this thread and never came across it in the other threads. Where are you gettin this information about Canzoomer's product?

Omicron

Read all about it in this thread https://www.rx8club.com/showthread.p...threadid=11614

It's long (26 pages at current count!) but well worth the read, if you figure 25-50HP is worth it! :D

Crashunit

First off, I must give Canzoomer a lot of credit to go above and beyond what Mazda should have done for us since the beginning. And as far as anything out there right now, his product is the best bang for the buck to regain our loss HP and mileage (I’m really disappointed at Mazda for having us look else where, and pay more just to have our cars run correctly stock). Hopefully, however, other big tuner companies will step up to this and create a stand alone unit, like the Power FC or AEM, that will allow us to self tune our car on the dyno or street with a wide band, and data login if possible. But until then, I’m really interested in what Canzoomer’s final product will allow us to do till then.

Some catalytic converters are built better than others. Too bad Mazda didn't just try to get the toughtest one made for the car that they could instead of hoping a new tuning would allow the cats to run for so long. I am a little confused though. My 2nd gen ran way rich for a while and I killed 2 cats in one year. When I leaned it out after proper tuning became available I never had a problem again. Then again, the 13B exhaust is hotter than the Renesis.

I think that if you run the engine at full throttle for 100K miles, something else may die long before the cats do. Oh well. I have no problem with getting under the car and replacing my cat in 99999 miles.

Thanks for the clarification Gordon. After a couple of dozen pages of reading it all starts to blend together.

Omicron

I think it depends on how much hotter your exhaust is. According to Canzoomer, the RX-8 cat is only designed to last up to about 1750 degrees Farenheit. If your exhaust is hotter than that, it needs to be cooled down (eg, by injecting fuel into it) or it will burn out.

His stage 1 mod is designed to keep the temp below 1600 degrees Farenheit, so the cat will be fine. Stage 2 mod exhaust temps will consistantly exceed 1800 degrees when the car is run up into the higher RPMs, which he says will burn out the stock cat in just a few runs... hence the need for a higher temp cat.

I think canzoomer should accept debit cards

I think he does...
