All other memory locations remain unchanged. When the vehicle 'reads' this location, it uses our module values instead of the original value. When connected to the ECU, the module overrides the specific memory location governing the feature we wish to change. Our module contains several memory slots, each with custom adjustments for a specific ECU memory location. "The adjustments are governed by our 'on the fly' programming. It monitors all incoming engine data and incorporates it into the tune." It can account for race grade fuel as well. "The chip is smart and does detect mods/fuel grade changes and adds them into the tune.

"Each vehicle is different, but typically it takes approx 250 miles/two weeks to deliver full gains." It is programmed for only one vehicle and has over/under voltage protection, power save mode, and intelligent learning.
#OBD2 CHIP TUNING REVIEW CODE#
The ST8PRO is our latest vehicle tuning module, and uses a microprocessor programmed with our custom code to provide improved vehicle performance. "We guarantee that all our products are not scam chips or resistor hacks. This will get me by until an accessible path to a "proper" tune is made available. The chip can (MPG's) pay for itself in as little as a year and has a money back guarantee from Sawyer Tuning. This is a "ground floor" tune that actually works and if you let the MPG's happen, you will get a couple. But I can tell you that this chip worked for me, much to my surprise.
Is this a technical analysis with dyno runs and graphs.no (maybe later). Ill report back again, should any changes occur after an extended period of time. Later.after a reset of the chip and a test of more than 300 miles, im up 2+ full points MPG. This may improve, as eluded to by the time table (a week or two) given for intelligent learning to adjust to personal driving habits over a period of time. At the end of my 1st set of runs (approx 220+ miles), I was up over +1 point MPG (with fairly aggressive driving). I consistently saw higher initial peak numbers on my MPG's. The idle is smoother, even reverse seems "less jumpy."
High-speed engine response is improved and cruising is effortless. It feels as though the "power band" has been expanded by a few 100 RPM's. The "low-end" torque is really there when you ask for it and the engine revs up to speed quicker now. The power increase is noticeable as the engine feels "more free" and responsive. That said, this thing actually works! Throttle response is quicker, smoother, and more even as well. I am going to leave the technical descriptions for Loren, I am just a novice "modder" having fun while getting the most out of our little platform we love so much. The $130 will pay for itself in about a year for me, if i can get a couple MPG's. I figured I had nothing to lose after being assured that the chip would not have any negative effects on the engine. The price is also $130, which is very reasonable.

The chip does detect mods and fuel grade changes and adds them into the tune". However, we are sure you will be impressed with the gains. Yes, all our products come with a lifetime warranty and can be returned if not happy with the results. "Yes, we support the 2014 Mitsubishi Mirage in the ST8PRO chip. I had a good back and forth with the Sawyer Tuning rep and he assured me of his guarantee of viability: Though, the Volo has some "tuning" customization capability that the ST8PRO does not. They essentially do the same thing and seem to share some of the same "hardware architecture". I was going to try the Volo VP15 as well, but decided to try the ST8PRO instead. Performance Chip Reviews has a review on the Sawyer Tuning ST8PRO OBD2 ECU Performance Chip: This could be just the thing to help me get more out of the header and exhaust that I put on my Mirage". Will do a new thread and review at some point.
"I went ahead and pulled the trigger and ordered one. But, for $129, all indications are that it is capable of doing what it claims". Again, not a full "custom tuning" solution. Here is forum member Loren and his initial take: Performance Chip Reviews has a review on the VP15 OBD2 Volo Chip: But there are now a handful of different companies that are using this "new" technique of adjusting air/fuel mix and advancing the ignition timing, via their ODB2 chips.Ī couple of these chips were mentioned and reviewed here: I know, I know ".its a resistor scam chip, it could do harm, its just a set of blinking lights.". I got the information, answers, and opinions I was looking for and was confident enough to have a go at one of these OBD2 chips. After some of the recent forum activity regarding OBD2 chip tuners, I did some research and began to ask some questions.
