Just curious if you guys had any thoughts or experience with this product. Might be useful in logging o2 readings with nitrous on a run.

 

Here's a better look at it

Kay, this is probably the most useless post ever, I was researching the sample rate of this product. It's fastest sample rate is once every 5 seconds. And seeing as the quarter mile is only about 13-14 seconds for us semi stock Zs, this product would only record about 3 times during the run. Not very useful.

I currently use the pocketlogger

www.pocketlogger.com

and it records 6 samples per second per parameter. A lot more useful than than once every 5 seconds. I just thought I had found something better. Oh well.

 

CarChip is really designed as a long term logger. I use mine to log stats over time so I can see what's going on with things like timing, A/F, etc. It's not a good tool for mapping short bursts (e.g. 1/4 mile runs)

So, while the pocket logger is great for getting lots of data over a short period of time, the CarChip takes fewer samples, but can record months (with the E/X model) of daily driving.

The original idea is to keep track of how the car is being driven, (for example, your teenagers.) I use mine to log milage I use for work.

 

Yea, thats what I figured. It sounded real good at first, but like you said, not good for 1/4 logs. I can see how it could be useful though if you let other people drive your car.

 

All these thing are worthless without a wideband O2 sensor. The stock sensors are only good for stochiometry (spelling?) readings.

You need a sensor that can give accurate reading at WOT.
