I think it would look pretty bad of the President of the M'sters Miata club showed up in his 8 for the dyno day. Maybe I could have the wifey drive the 8 over.

Anyways, what is involved with dynoing the 8? I have heard that without the front wheels spinning the car can go into limp mode. Anyone have any idea on how to properly dyno the 8?

my10ae,

Check your e-mail.

Wow! A lot of info in this thread. Unfortunately I can't look at the last posts for conclusions and have to follow from the beginning posts.

In order to help me digest this info, I am copying the posts into MS Word. The posts were written in a casual conversational style, so I'm editing for clarity, eliminating extraneous words, combining sentences, explaining abbreviations, etc. I'll re-read the results and see if it makes sense to me.

I have an AT, and if I can understand how to tune it, I'll make the leap to the Canzoomer unit. This seems to be the most efficient, least invasive way to increase horsepower, allowing you to return the car to stock condition easily.

Thank you guys for your hard, pioneering work. If you could, how about a summary of your work on how to tune Canzoomer for the AT, for us dummies. We are not worthy, but we'd sure appreciate it. :D

After the MS Word edit, I got a better understanding, but lost it half way through the thread. Don't know. Don't know if I should jump in an buy a canzoomer unit.

Speed Racer

When you get a chance, post up your MS Word file. I'll review it for content and add more detail where it is needed along with some photos and/or screen shots.

I'll let you know shortly. I purchased a used system and should receive it soon. Speed Racer has offered help and I hope he does not live to regreat it

Phil:

SR is a good guy. If he had the patience of me asking dumb questions over and over about tuning the CZ unit, you should be fine

rodmeister

Darn, my MS file was wiped out when I transferred it from my work computer to my home computer. It will be some time before I do it again. Sorry, but I give up easily.

Phil@desertboilers.com:


Did you get your CZ unit yet and have you started tuning? Just curious..

I was away for a few days of R&R and just returned home. Got the CZ unit - I just forgot I need a lap top. The lap top that I will be using belongs to the company and will be in use for the next week or so (also a little intimidated).

There was a note in the box with the CZ:

"I don't have the stock map installed. I tried to install another map. Be sure you get the stock map from someone. I never saved it You will need to reinstall the stock map before running your car. Enjoy"

Am I in trouble??

Speed Racer

No, this is not a problem because we are going to make a custom map. I'll send you the last map I worked on with my10ae. That should give us a good starting point.

MDRX8

Does anyone have a good stage1 or waterd downed stage 2 map? Last I have are from sept 04....

Spr Grn8:

How are you making out with tuning your 8? I haven't heard any updates from you in quite sometime. Hopefully you are enjoying the added power that the CZ unit offers. Please let us know.

Speed Racer

my10ae,

So how is the CZ doing with the warmer weather? Do we need to make any minor adjustments?

my10ae

SR:

Things have been running pretty good so far. I do get a "slight" hesitation when in 3rd gear around 4600RPM. I think the warmer weather has changed a few settings with the A/F ratio. Maybe I should do a few runs and log this incident and then you could review and let me know what you think?

Other than that, the CZ runs great, even in the warmer weather.

Speed Racer

Yes, try to catch the behavior in a data log and we'll get it sorted out.

I copied the thread on install and got the pictures. So I don't embarass myself I will try to hook it up as shown. I can just turn the switch to off so the unit should not effect me untill I am ready. If I have any hair left and my nerves are under control I am thinking that the first trial will be Friday evening - Saturday Morning. My grandkids are all over me to take them water skying on Sunday so nothing will get done then. Unless something prevents me, you should hear from me on Friday at the agreed upon time. I do not have the internet at home so if I need anything before I call let me know now. I get on line at 4am (my time) Monday thru Friday

Sorry it took so long to get back to you. Speed Racer and I have been talking and we drug Morice into it also - had a problem. I'll be trying again in a coupe of days. I'll let you know how it goes.

Speed Racer

Did Maurice help you out with the getting the cable to show up on a lower COM port?

If not, you should ask your guys what items have been plugged into the computer (i.e. printer, keyboard, mouse, camera...). If you can get your hands on any of those items we can then plug them into the laptop and see how they show up in the device manager (i.e. COM 4). The trick is to find something with a low COM number. Then we can uninstall that item and use that COM number with the progamming cable.

I know this is a pain but it is only thing I can think of to free up a lower COM port and allow your laptop to communicate with the CZ unit. Maybe some of our resident computer gurus can offer up some other suggestions.

my10ae

DOH! the dreaded com port issue and IRQ interrupts. Don't cha love pc's? :D

Speed Racer:

Well, Maurice got a com port to work (com 4). Talked to my Techs and they have Com 1 and 2 configured for a pug(s) into a boiler controls system and have asked me not to uninstall 1 & 2. They tell me that the program they are using requires those ports.(?) If this becomes a problem then I'll just get another lap top.

My 8 is headed for the shop today and as soon as Mazda repairs my a/c, I'll start again.

Speed Racer

COM 4 should work fine for the Greddy Support Tool. We also need the CANscan to show up some where between COM 1 and 8. Then we should be good to go.

Another problem poped up. My radiator cooling fan seems to have a mind of its own all of a sudden. I havent driven the 8 since it came back from the a/c repair. Was hooking up everything and when I turn on the ignition to power the tuning computer and it also powers my cooling fan (car had not been driven - cold). I think it's going back to the dealer. I searched the posts and have not seen any problems with this fan.

If what I need to do does not take long I am willing to go ahead but do not want to draw down the wimpy battery to much or cause another problem. Suggestions??

We got moved - This may encourage others to tune their a/t 8s

Speed Racer

I'd hold off until the fan is fixed. Let me explain why. The fan turns on when the ECU sees that the coolant is above 190 degrees. It can also cut back on the ignition timing and richen the air/fuel ratio in attempt to protect the engine when it is hot.

Seeing that the problem just showed up I'd be inclined to think that this is probably caused by a loose connection. Before you take the car in to the dealership double check the connection to the coolant resevoir. If that doesn't work I'd remove the CZ unit to see if the problem goes away. If not, make an appointment with the dealership and let them track it down.
