I Just put up the article i wrote for RxTuner on the Zoomer unit in PDF format on www.rxtuner.com , direct any questions you may have for me or about the unit here.

good article.

It’s unfortunate the results were not impressive on your car. Good luck with the tuning if you keep the CZ.

It would be nice to see a detailed article on the tuning aspect of the CZ and/or emanage.

[Edit]
Nevermind...I see you are selling the CZ.

thanks for posting that, a good read, should help people decide if that is a mod they want to buy. It also does a great job describing why it doesn't work for some people.

Really good article. I wonder if Canzoomers just making an aftermarket (less variable) MAF sensor would just be the best idea. It seems the poorly made MAF is the cause for a lot of problems even with stock RX8's (Why some dyno in the 170's and some dyno in the 190's)

You wisdom shows no bounds young grasshopper.

So is this a CAN Bus problem, or a wiring harness problem??? Or do you know yet?
Are you measuring the impedance from the ECU side with the different MAF's

I know they sell aftermarket MAF's, are they of better quality? Is the purpose in getting one to fix this problem? It sounds like we need to get Polak's A/F and volatage specs since he is dynoing in the high 180's and use that as baseline. This sounds to me like a fairly simple fix is its a MAF and MAF to ECU issue, were talking about pretty basic wiring.

In a perfect world...wouldn't the e-manage give us the ability to make the ECU think the MAF is doing what we want it to?? ( custom tune)
Is the impedance problem constant, or variable?...a constant should be easier to deal with
Are the Sensor outputs to the ECU all analog...

Lemme get this straight you measure your MAF voltage input then took out your sensor and replaced with a sensor from another car that measured higher then yours.

Then you measured the Voltage again and it came out to be the same. It may not be something as complicated as interplay between the ECU and the MAF.


Isn't most of the voltage lost in a circuit thought the wires? Could varying degrees of wiring and wire harness quality be to blame?

In this case, the wires are very short. They probably don't contribute greatly to a drop. I would blame the input resistance of the ECU which could greatly effect the measured voltage of the MAF. The ECU may not care about the variation though, It may be focusing on ratios and rate of change. Using other available info like temp, TPS, RPM, etc to determine the correct action.

A software solution to using cheap MAF's and keeping the car under $30k. Also, keeping tuners from easily defeating the built-in protection schemes the ECU has. If that is true - BRILLIANT on Mazdas part.

I've never understood this whole "prevent tuners from coming up with ways to make the car faster"

I don't see why the manufacturer would deliberately make the car harder to tune. People tune the car, which makes it more attractive to buyers (in that market) so they buy more cars.

Heck, Mazda has their own line of performance parts. It's not like they don't want the car to go fast.

I'm just betting it's the auto-software revolution as of late. If it's hard or expensive to do, just write software that does it for us!

It's sort of like F117 syndrome. Due to the odd aerodynamics of the plane (for stealth purposes) it would be impossible for a human to reliably fly it... so they just stuck a computer in it that would automatically adjust the flight controls to smooth it out.

Instead of building a car that ran great by itself, they built a car and then put a computer in it to make it run great.

.. or something...

Polak, it would have been interesting to install the unit in your friend's car to see how it then compared against your own. Otherwise good article.

We did.

I quote: "We pulled into a quaint little neighborhood and decided to give some-thing else a shot by installing the Canzoomer Stage 1 unit into Shawn’s car. Thanks to “Old Man Stewart” for lending us that screwdriver, and the nice ladies next door who gaveme a bandage after cutting myself. Once again 3rd gear pulls up to red-line, my car pulled away just as much ifnot more then the stock to stock com-parison run. The unit was obviously notproducing the power it should and itwas odd that my car was so muchquicker stock. So before I wasted moretime on the dyno I contacted Mauricewith my findings"

Sorry. I read your article friday and forgot about that bit. A track day at Laguna Seca and autocross the next kinda drove that little fact out of my mind.
