Keep an eye on the RX-8 Parts For Sale/Wanted forum. It seems like there is normally at least one CZ unit listed for sale at a very reasonable price.

Ive got a question for you guys who have this installed - how easy is it to pop the CZ unit off my car (along w/anything that can be traced to it) and then pop it back on? Im just wondering b/c I know thatmy service rep wouldnt be too thrilled to hear one of his mechanics telling him about some ecu piggyback sitting under my hood the next time I go in for service.

Also once you disconnect all traces of the unit only to reinstall everything hours later - does the ECU easily adapt back to the CZ units tuned settings - or does it act stubborn forcing you to go over everything all over again?

The first install takes the longest because all of the connectors are tight and you are learning your way around the engine bay. So plan on it taking about an hour for the initial install of the CZ unit into the ECU box. Converting it back to stock, before taking the car in for service, takes about 15 minutes and you can do all of the work with just a 10mm socket. Likewise you can reinstall the CZ unit in about 15 minutes. That is one of the perks of this setup.

If the maps are done correctly, you shouldn't have any problems with switching between stock and CZ.

Updates!!!!

Sorry, no updates from me this week.

Let's see if my10ae or spr grn8 have any news.

Hey Guys:

Nothing really new to report regarding the tuning of the CZ unit. Everything seems to be running smoothly for now. Will probably have to adjust the timing when it gets a bit warmer around here.

I did install a Borla last weekend. Gotta love the deep throaty sound it give the car under acceleration. This is how the exhaust on the 8 should have sounded. Along with the added HP from the CZ unit, the Borla just added icing on the cake

Gtech!!!!!

Sounds good my10ae - whats next? Midpipe to top it off and pollute your surroundings? :D

FYI - there is another CZ unit for sale in the RX-8 Parts For Sale/Wanted forum.

Hey, I had the N-Flash done last week and ran a data log with the canscan. I posted in the N-Flash PCM thread in the tech garage about my results. Drivers with the AT RX8 should
read it , it might give some insight about tuning with the new flash. If the data log is consistent, the only tuning I/We may have to do is tweaking AFR's above 5K Rpm. Similar to the adjustments SpeedRacer sent me initially. After the re-flash to N, AFR's are almost perfect below 5k rpm.

Spr grn8:

Glad you are making some headway to tuning our auto 8's. Did you say that since the N flash you don't need to adjust the ARF's below 5K? Where abouts are you tuning it right now? Speed Racer and I have only touched the AFR from 6K to redline. (I have the M flash) I have adjusted timing from 4K to redline and that has seemed to help a lot. I really has a nice kick between 4K and 5K due to the timing advance.

Keep up the good work.

I would like to get the car dyno'd to see what she is pushing at the rear wheels. Anyone have a baseline dyno pull for a stock auto 8?

spr grn8

Yes, i had the N-flash done last week. I will try to get more data logs to verify the AFR's below 5k. My next tuning will be similar to what you have done above 5k (6k). Right now i would focus on AFR's and timing above 5k. Here's my .pdf file log from the other day.

I wish I could follow what you guys are doing

I would buy the unit but I wouldnt know what to do with it

snizzle

yeah anyone written a canzoomer for dummies?

my10ae

I'm a dummy and I learned it (with some help from Speed Racer) :D

Speed Racer

You are not the first person to ask for that. Check out this thread for more info.

snizzle

crap, how did I not see that... it's a sticky

Speed Racer

Hey we all zone out by the end of the week! Well at least that's my story and sticking with it. :p

Speed Racer

FYI - there is another Canzoomer and CANscan for sale.

My10ae,
You may have already posted this and I just overlooked it but how is your fuel consumption now compared to what it use to be before the canzoomer?
Thanks,

I do understand the need for tuning and understand that the 8 needs some but that's where it ends. Most of what you are talking about and doing is WAY over my head. I've read the "dummy" post and it still is confusing. Since no aftermarket manufacturer seems inclined to tap the automatic market, My question is would it be to my advantage to purchase a C1(.1) and find a local tuner?

snizzle

so all the additional power comes after 4,000 rpm, correct?

any estimations or dynos about how much power is really opened up here?

Speed Racer

Phil,

At first tuning the CZ sounds very daunting but honestly it becomes much easier after you do it a couple of times. It is just time consuming. Give me a call and I'll walk you through it. Check you PMs for my phone number.

Speed Racer

Snizzle,

Yes, all of the adjustments were made above 4k RPM.

FYI - my10ae is the President of the M'sters Miata club and he has reserved some dyno time on Saturday for the club. He is obligated to bring the Miata but maybe if you guys give him some encouragement he would find someone to drive his RX-8 over to the shop too.

I'd like to go but my weekend is already booked.

My fuel consumption has actually stayed the same since installing the CZ. Nothing scientific here but on a full tank of gas, I can still go 240+ miles, just like I used to be able to do before installing the CZ unit. I know, I know nothing to back my claiming of a measureable "tank" of gas. All I know is my gas consumption has stayed the same since installing and tuning the CZ unit. :D
