It is not very fast, definetly not a data logger for fast runs but more of a diagnostic or play tool.

 

I played with mine today.

It seems that the speedo on the OBD II runs about 1-2 MPH slower than my digital speedo on the car. Also seems like my Tach on the OBD is lower than what I see on my dash tach.

I did some quarter mile runs as well and all I can say is I SUCK at launching! I had it down really well before the blower but now I spin tire something fierce!!!

My 0-60 time was a crappy 5.4 sec.
My quarter mile was a crappy 13.62 sec.
My Trap was a pretty good 112 MPH.

I may have to sell my G-Tech. This thing does all that the G-tech does and more and you don't have to stick it to the windshield.

 

curious as to how the results compared. oddly spinning wont hurt you with that system, actually may help...

it doesnt know your spinning, it assumes perfect traction.

unlike the Gtech, which measures Gforces.

 

It starts the clock when it detects movement. When I am spinning I am DEFINITELY moving.

 

OK here is first data, I let the car idle for 10 minutes and final readings were (average of last two):

RPM = 675
Coolant temp = 197
Timing = 18
Intake temp = 109
MAF = 3.08

Rnage of readings during 10 minutes:
RPM 650-700
Timing 16-18
Intake Temp 104-109
MAF 3-3.41

I had the car half way in the garage with the front inside.

 

what was the temp outside? Im guessing hot.

during short idle periods on my ride home intake temp climbed to 119degrees and during movement came down to 101.

dash board temp read 83degrees.

side note, I ordered a USB flash drive so I can get the data to my desktop, but itll be a week.

 

I knew I forgot to take a parameter down, but it was warm down here in the 80's, it was in the mid afternoon and it was in the garage so no breeze.

 

I logged about 25min of my commute home today. 84degree sunny day.

in traffic intake temp got up to 140degrees open highway down to 102ish.

MAF varied from 4.8 at idle to in the 60's at WOT at about 5000RPM.

coolant temp was a very stead 189ish

tried to play with the dyno, but its amazing how difficult it is to get caught as the first car at a red light. first time, I got 180hp; clearly didnt quite do it right, next time I didnt know to hit reset, just hit start, after I reset it started, but I was already doing 60, but I tipped the scales at 5000hp. I was pretty satisifed with that run, so I think Ill keep it.

I also pulled off a 38sec quarter mile in traffic, I think I can shave a few 10ths off that though.

 

Could someone please send me some of their log files when idle and normal driving conditions? I want to compare my O2 sensor and voltage readings for banks 1 & 2. I'm having poor performance issues, and I really need help comparing my car to others.

Thanks.
