I installed my Stage 1 last night and took a test drive. There seems to be a bit more power but nothing monumental. I guess after waiting 4 months my expectations kept going up.

I'll be taking my 8 to Atco Raceway soon to get documented numbers on the gains.

So how do you guys like your Stage 1??

 

I feel the same way. It seems to pull harder all the way to redline but it would have been pretty hard for it to live up to our expectations considering all the hoops we went through (actually epitrochoid went through) to get it. It seems to have more power throughout the rev range. I only have about 30 minutes driving time on it so far so more time will tell.

The car is definitely more responsive than before and my exhaust seems quieter now.

I can't wait to see your numbers. Are you going to do runs with Stage 1 turned on and then turned off?

 

I ran the car at Atco with the exhaust only and my best was a 14.8. Here's the time slip.


Car #202

 

Sweet. Can't wait to see the improved (*crosses fingers/says hail mary) numbers!

 

v8, what were your times before stage 1.1?

 

do you guys all have the "M" flash or have you just put the unit in regardless? My car is going in for service on tuesday and I'm going to have them reflash it to M (or punch them in the face if it comes to that, whatever) and then i'll put the canzoomer gadget in. Is anyone running their 1.1 without the latest flash?

 

That time slip is before the ECU. I just put it in last night silly! :D

I'll go back in about a week.

 

hey fellas, quick question: What flash are you talking about? I asked the service manager about any mods from Mazda to improve the mileage on the rx8 and he said no. I do plan on getting a CZ stage 1 or 1.1 because my mileage really sucks, literally! Thanks.

 

i installed it with K flash, it idle's rough and the high rpm isn't smooth. its fast though, I beat a z28 after 100mph from a 60mph roll

 

I have the "M". Maybe I should list that in my sig as a mod? :D

 

yah be "coool"

 

Installed mine today...Definitely notice a difference. The rpm's rev alot faster and the engine seems to have a higher pitch whine than it did before. However, the car idles rough as hell with it installed. I thought I had M however after the rough idle I think I may have been given L instead of M. Unfortunately my work order for the recalls, etc didnt list the part number of the pcm reflash. The brake pedal test works but I suspect I got L and thats why it idles rough. Gonna give the dealer a call tomorrow and have them look up what flash I got.

Regardless, I do love the increase in power it has given. The beep comes on before you know it!

 

does your idle start out fine and they get rough the more you drive, regardless of how hard you drive? thats how mine is....I didn't have M either

 

my car does this normally (without stage 1.1)...drive it for a bit, sit in neutral, car sort of shakes and shudders. it has done this since I bought it.

 

I have the M flash and 1.1. Idle is fine. Maurice had stated that the new tune was compatible with all flashes but everyone that puts it in with L flash seems to have minor problems.

 

I have the K flash. My car lost about 5-7hp with CZ1 AND ran roughly. I did about 12 or more pulls on the dyno. CZ on= rough running and about 176ish hp. Turn it off or pull it out=183ish hp smoothly.

Spoke with CZ, I was going to back-date the CZ1 with an earlier program designed for K's, ordered that an month ago. No word.

Not a particularly good performance buy. About $100 per LOST hp. For another $5,000 I could have a Honda Civic.

 

Epitro,

Yeah, when i first turn it on it idles perfectly fine. However once I start driving and then come to a stop it idles rough. I did notice this morning that the tach didnt bounce around as much as it did yesterday. I hope that getting a few more miles on with it will smooth out the idle. ONly time will tell....

 

My idle is noticeably more erratic since the CZ1. I've also noticed more power. :D

 

it has been stated that there's a 50 mile 'learning' period for the PCM too....

1strx8 - i dont know what the story is on your car, but I'd be weary of putting so much stock into anything coming off a dyno with this car. the power was right there, especially after the 2-3 shift. i could understand if it lost several PEAK hp due to mismatched maps and flashes, but I think the total area under the curve is still greater, and that's what counts.

 

I have only put about 40 miles on my car since installation and it does seem to be settling down more each day. The power is definitely there and ready to be unleashed. Get outta my way, I'm coming through!

 

2.3 sec 60' time? isnt that kind of dismal even for street tires? taking .3 off that should take .3 off the total, right?

I can post the dyno data. the AFR after 5.5k goes way lean and the hp plot indicates a major power drop - ACROSS THE BOARD.

Turn the car off, take out or disable the CZ1 and do another pull within 3 minutes. It is way smoother and makes significantly more power.

The data is on my home PC, I will post it from there. FYI I did talk to CZ, he is sending me the software to back date the CZ1 program for K flash. I hope that works.

The dyno may or may not be showing the full power output capacity. IMHO, it is very close. I would be surprised if it is making more than 220hp at the crank. My car indicates about 183ish at the wheels which sounds close at least.

It does, however, indicate changes. The CZ1 is not doing anything good right now, it does not feel faster OR measure faster.

Maurice will get it right - soon I hope.

 

yea...i dont think running an M tune on a K pcm is a good idea. that's why i pulled my unit until I can get flashed or my data cable comes and I can put the K tune back on.

but damn, to loose power being too lean means it's gotta be on the other side of stoich...that's just plain bad!

 

yep.

 

It will be fixed just in time for the Turbo mods.
