Product Description
No comments are necessary this summer about the cost of gas! At 4 bucks or more you have to make sure your vehicle is in tip-top shape for the most economical performance. Did you know old spark plugs can reduce fuel economy by 30%? It gets worse... a bad oxygen sensor cuts it by 40%! And that relates to a lot of extra gas and money! With the CarChip Pro you'll have complete access to all your vehicles diagnostic data at your fingertips! Sort miles by type, business or personal miles, set thresholds for alarms, calculate gas mileage, log extreme acceleration and braking, speed, engine parameters, and a whole lot more! And as you know, extreme acceleration does not equal fuel economy! Find out whos driving your vehicle like a race car...and deal with it! If you have a new driver in the family, monitor their performance and let them gain additional privileges with a good driving record! You have the proof! No more taking your car in to see why your check engine light is on. The CarChip Pro will automatically provide the trouble codes and allow you to reset it! CarChip Pro includes storage for up to 300 hours of driving data! If you're unfortunate enough to be involved in an accident, it even records the last critical 20 seconds of operation! Includes USB cable, software and complete instructions.

 Carchip data logger. July 2, 2008
Roger W. Brown Jr. (San Diego, Ca United States)
My purpose was to collect LTFT, STFT, and Upstream HO2 Voltage periodic test runs. DTC and emission readiness is Ok but not primary. br /User choice data are limited to 5 selected sensors, one of which is assigned to mph. Leaves 4 and needs two more fields. V6 has two banks each LTFT,STFT, Upstream HO2 = 3 each bank. Limits choices and data. I collect LTFT, Upstream HO2, copy and paste in excel for analysis. Adequate but would be much better with STFT. Sensor will not record Wideband Air Fuel Ratio sensors and that's what my 05 Accord V6 has. I use LTFT and STFT. (Am I over 13? Better ask my wife)
 An excellent unit for improving driving habits April 28, 2008

First, the unit has been replaced with a newer version called the CarChip Pro (which is what I got). While the first unit I got was faulty, they shipped a replacement immediately - an A+ for their customer service. br / br /I got it for a series of uses. I am considering switching over to an electric vehicle for our commuting use (best alternative with high gas prices, oil wars, climate change, etc), so I first wanted to really dig down into our typical driving so that I can figure out the right choice for us. br / br /It is a "plug and play" unit and the software is extremely easy to use. Literally, just plug it into the OBD-II port. Pull it out and plug it to your computer and press a button to download the data into the CarChip software. Then plug it back into the vehicle. br / br /Saving the trip data to a CSV file is relatively easy for a single trip. But to do it for several isn't - one has to keep repeating this for every trip. Bummer. br / br /I created an Excel file with some formulas for deeper analysis. I found that on our city commute trips we use engine power for only 40-50% of our trip duration (the rest is either idling or coasting) - we are excellent candidates for commuting using electric mode only (either an electric vehicle or electric mode only in a plugin hybrid)!! To put in another way, we are wasting gas for at least half of our trips. br / br /My area is hilly with plenty of slopes - some steep but most are mild. So I now tried "saving gas" driving techniques in our compact manual shift car (2002 VW Golf). Been doing that for about 4 weeks now since my last fill up. And no, I am not driving like a "little old lady" - just preserving momentum well and using gas judiciously. I've logged my driving over the last month (Apr 2008) and got 37 MPG!! That is significantly over the 23-24 MPG I got before I changed my driving style - a 50% gain. So I expect to recover my cost in just a couple of months. br / br /So after a few months my need for the CarChip is almost nil, right? Well, not really. While one can continue to use it to monitor car usage, mileage, etc, it can also be used to get an insight into the computer error codes and take action before it becomes too bad. br / br /The unit retains the last 20 seconds of speed data in case of an accident. So it can be used to advantage. However, I am not aware of the validity of the data from a legal perspective, a good lawyer should be able to use it to "win the case". br / br /The unit also captures hard/extreme braking and acceleration. While hard/extreme braking is required in certain circumstances, it should be minimal/none for a good driver. Both are not good for gas mileage as well. This information can be used to improve driving style. Since my older one will be of legal driving age in a couple of years, I plan to have this unit in his vehicle for the first few years to help him improve his driving habits. br / br /While it is a no-brainer for fleets, it is good for the average family too.
Great little gadget! March 16, 2008

I got this thing on a lark and frankly I am very impressed. It allows me to easily track business mileage, time on jobs, driving behavior and a lot more. It also lets me clear "check engine" lights and has user programmable alarms for engine issues, temperatures, excessive speed, excessive acceleration and excessive braking. These beeping reminders are helping me to drive less aggressively and to save gas. And I can change or turn off the alarms any time I choose. And the data logging capability is rather impressive! br / br /And of course it painlessly captures all car computer diagnostic error codes and allows you to display them on hour PC in English. br /
 Great Item! February 25, 2008

I had seen this product that a friend of mine had for a long time. I was excited to get one when I got a car that would meet the qualifications. I just bought this this last month. I have traveled over 1000 miles already with it and is works beautifully. It has a LOT of potential for car up-keeping, but it also already does more than I thought it could. It is great for keeping up mileage, MPG usage, self-troubleshooting, breaking bad driving habits, and much more. I highly recommend this product and will get another one for the rest of the cars that I get.

The first one only lasted 6 trips before it "fried". Called tech support and they said they'd send out another one right away. That's good! I'll write more when that one gets here, for now, it didn't work.
