Folks,
PLEASE READ THE FAQ THAT DOC KEEPS REFERRING TO!
You guys are making this seem like its the hardest thing in the world to use. It really is not! If you have used any of the many other units out there, than you are more than likely going to be very comfortable with this unit. I have tuned with a bunch of the other devices that make up the "alphabet soup" in the world of piggybacks. If there is one common thread with all of them, it is that you have to know/understand what it is that you are trying to alter/correct, before you start making changes.
The MaftPro has a great advantage over many of these other device in that it allows you the flexability to monitor all of the vital signals from the various sensors right on the unit itself. It comes with very easy to follow instructions, which will put you at probably 90% of your tune. You don't have to worry about this thing making radical changes to your system because you will control all that. You can set this thing on "auto pilot" via the AFR tracking feature and allow it tune the WOT map to your desired a/f ratio (provided that you have a wideband 02 sensor). You can datalog your run, and then set your own settings to mimic those that the "auto pilot" made. Again, you have to start with small changes so that you can trace back the effects.
YOU DON'T JUST INSTALL THIS (or any other device) and RUN 25 PSI RIGHT AWAY!!!!!!
You should take the same approach to tuning with this unit that you would take with any other. First and foremost, make sure that your car is set to handle the added power, and that all sensors and parts are in good working order. Many of the problems that are often reported are the result of people trying to tune their car with old or defective parts. Old sensors, cracked hoses etc.. will send false readings to whatever unit you are using. That will make it impossible to tune any car with any device! So just make sure that your base is in good working condition before you start to build on top of it.
Aside from reducing the cost of having to buy the multiple devices (VPC,GCC, AFC, Lexus AFM etc..) by having all these features in one unit, you also get to reduce the chances of multiple units not working in sync with each other. This will also reduce the amount of time that you spend diagnosing issues and trying to figure out which unit it is that is messed up. All of your tuning will be done with one compact unit! you will only need to refer to the Maftpro if something is not working. you can datalog from it and see if maybe a sensor is not giving the correct signal.
An unfortunate reality with the MKIII community is the number of "window shoppers" in it!
Take this particular thread for example:
23 pages, 230 posts, and a grand total of 3 buyers!!!
How will we ever know how well this or any other product works if noone buys it???
If you want to know how well this unit works, go over the Fullthrottlespeed.com website and read about the many cars running 11 and 10 seconds ET with the Maftpro.
While there, you will also notice the number of other devices and support provided to these other cars. Why is that???? Because they actually buy the units and run them, which allows for the makers to develop better programs and units based on the feedback they receive from these customers. How can we expect perfection when no one wants to step up, buy the unit and give feedback?! Ask any of the guys making big power, what it takes? They will all tell you that "you have to pay to play"!
