Thanks mate. I used to do stop watch and gtec for last 6 years on civic and ITR, what counts is the "consistency" of the outcome rather than accuracy as compared to drag racing results. G tec tends to read 0.3-0.2 sec slower than my stop watch. At least, I know, its the same driver, same manner, same road and same style. I was able to hit 110 in between the two speed bumps that I used to do with ITR and ..at least that tells me, corolla is doing well. I think its to do with new car and 6 speed with low diff(4.6) and a very good traction at launch as compared to my other cars 215/17/35. also, less power is lost thru trasmission and engine. So despite either its accurate to you or not, at leat at my "system" its working quite consistent. I will do two more runs this week, to further confrim my findings. as a scientist, consteitency counts more than any thing else. Thanks Consitently inaccurate? LOL. Consistency doesn't equal accuracy, though. If you're from Sydney, take your car to WSID and post your quater mile times. Your E.T and your trap speed is a much more meaningful figure for comparison.
