Yup, 2.3 60' isn't anything to brag about. I did not drop the tire pressure when I did those runs. My experience so far with the 8 is that it is hard to get a good 60'. Yes, a drop of .3 on the 60' should equal about the same on ET but not always.

i put mine in today, install went smoothly and no CELs or anything. Haven't had much time to drive it yet, but so far no problems.

e-manage software came in today. I will upload the K flash tomorrow and I have yet another dyno scheduled for Friday AM.

regarding the 2.3 60', the light flywheel might help with that. car certainly seems to spin up slow in 1st.

lower gearing might help to get into the power band quicker- smaller diameter wheels/tires are my idea here.

drag racing is for the birds...

Velocity-8

Why do you say that? I agree using the RX8 for a drag racer is a waste but timing your car to see the improvement of mods is valuable.

So, everything was fine with the CZ for 3 days. On Tuesday, I was on my way to the shop to get my springs/shocks installed and my Check Engine light came on.

When I picked my car up later that day (8 hours later) the light was off because the battery was disconnected for hours.
2 days later and the light is on again.

I reset my PCM this morning before work (by doing the 20 brake stomp) and confirmed the oil needle swept.

Light is still on.

I am going to work on my car tomorrow. I will pull the CZ and see if the light goes out.
If it does then I will install my stock airbox back in...put the CZ back in and see if I trip the light again.
Does anyone else have any other suggestions?

1stRX8

Totally.

A 1 1/2 hour enduro road race in a GT2 car is racing. Side stepping the cluth at 9,000 rpms for 14 seconds is so boring.

SMigneco, i got one too. Installed my CZ on Sun. got a cel last nite. ran my new canscan obdII scanner ( i love it!) and got the error code. I got the P0300 engine misfire error message.....I turned off the CZ last nite and the light was off this morning when i went to work. Gonna take it to mazda tomorrow for them to check it out and clear the code.

Velocity-8

Can I borrow your GT2 for a few hours?

Like I said - 1/4 mile times are good to see the difference the mods make. I'm interested to see how much real world power the CZ1 makes on my car. For $12 and 45 minutes I'll have real data. Plus the track is only 10 minutes from my house.

1stRX8

Correct. It does give you a quick indication of the effectiveness of engine mods.

I have the fortune of a dyno shop 100ft from my office.

epitrochoid

intake + stage 1 is a well documented bad idea....pull that intake and reset, I'll bet you'll be fine.

but would it cause a misfire? i dunno...make a post in the CZ forum about it. because i could swear mine was missing too

Genom

Ya'll are running 89 octane or higher right?

1stRX8

I'm running Mr Fusion, trying to stay under 88mph though.

Shooter: Did you bring your car to the dealer? What did they say?

Shooter

Yeah, i took it to the dealer. But i uninstalled the CZ prior to going, just in case they decided to crack open the ecu....Well unistalling the CZ erased the stored code I had. It had a new stored code, a DSC error, obviously because I disconned the CZ and reconnected the ECU. They ran a full diagnostic and found everything was fine.

My brother was in town for the weekend and he is alot more of an engine expert than me. We did some Gtech runs stock, then I reinstalled the CZ. Did a run with CZ and there was a difference from stock however the idle is still awful. He said it sounded like misfiring to him and he advised me to turn it off until i hear back from CanZoomer. I ran my OBDII scanner and it didnt throw any CEL's in the 30 mins or so I had it installed and on.

Just waiting to hear from CZ now on what the next step is.....

2001F4S

Well I was all excited to put in the CZ ECU once received. Now I have alot of concerns.

Am I correct that you guys are saying that it does not work well with the L flash or newer?

Thanks

h0rde

"does not work well" is debatable I guess. The majority of us notice more power but we also notice that the car doesn't idle well with the unit installed, but we're not sure if that's a bad thing necessarily. I made a thread about the rough idle so you can see what you'll probably be in for at least...

I gteched my 8 with the cz 1.1 on and with it off. THe cz only gained 1/2 hpw from stock.

My car also was horrible while ideling.

Took the damn thing off all together. I would highly recommend waiting for another solution as now instead of a plug and play they are saying all cars are different and need to be independently tuned.

1stRX8

The hesitation on my CZ has all but completely gone away, except from the subtle lag you feel with the port openings. I think the PCM had a bit of learning to do. The car idles really well, starts well, and feels strong. My butt dyno isn't worth anyting so I am going back to the dyno for the 3rd time. I will post those results when I can.

I am also working on a heavy-duty cooling solution for the PCM box, it needs one.

adrian-1

How much of a difference did it show on the gtech?

SMigneco

OK. Here is what I did...

When I first installed the CZ, I received the CEL after 3 days. I received the CEL on the way to get my springs/shocks installed (which, by the way is the best mod so far). Anyway, after getting my car back the light was off for 2 days (maybe 1 day) and then it came back on.

I did not want to pull my K&N (very difficult for me) so I pulled the CZ because it is much easier. CEL went off. Then I though about it for a few days and decided to try something. I put the CZ back in. After it was in I waited an hour with the battery disconnected. Started the car and cleared the DSC. Turned off the car. Turned the key to ACC and reset the PCM by doing the 20 brake tap and confirmed my oil needle swept. Since doing this I have not received the CEL and it has been a couple of days.

My idle is fine as long as the car is cold. Once the car is run hard for 10 to 15 minutes then the idle is horrible. I really didn't notice it at first because I honestly did not run the car hard for very long. My commute to work is less than 10 minutes.

I fear burnt coils because of what happened to Genom and we are both in FL. I also really hope that there is some way CZ can fix the idle issue. It has not stalled yet but it sounds like it right on the verge of stalling.

Do you guys notice the rough idle when the car is cold? I thought the CZ did not kick in until 2,000 rpm. Am I correct? If so, then there is obviously something wrong because the CZ should not affect the idle. Perhaps everyone's idle is fine until the first time the CZ kicks in. Say you start your car and let it warm up for 10 minutes without going over 2,000 rpm. Is the idle ok? If so, then is it possible that the CZ is kicking in (for the first time) and, for lack of a better term: not turning itself off? I am just speculating here, but obviously something is not right.

I have decided to keep the unit in the hopes that CZ can get these issues straightened out. Maybe we all should invest in the software/cable. Perhaps CZ should start including those as part the of Stage 1 purchase because it seems that there are so many issues now that getting the cable is almost a must. He can then setup his ftp site with different maps for different climates and sea levels. That to me seems like the only way he can continue selling the stage 1's without getting them all returned after people see the rough idle and minimum hp gains. I have put my trust in CZ by not returning the unit and I really hope I do not get let down.

Lightweight flywheel here I come...
