SGII shows best acceleration load

[SentraSE-R]

christofoo, my motivation was to determine whether the SGII performance data logging could determine best acceleration load. You're correct that I haven't found BFSC graphs for my 1NZ-FE engine. The SGII does that job.

Videotaping a pulse cycle is remarkably crude, imprecise, and laborious compared to the SGII's ability to log fuel consumption, speed, and distance every 0.4 sec.

Xist, trying to hypermile without a gauge is like trying to learn to drive while blindfolded.

I accept your challenge!

I wish you well, but you are seriously handicapping yourself without instant feedback.

I was referring to driving blindfolded, but purchasing a Scangage is a priority after I find employment.

My comment was applicable to either situation .

My mom used to meet elderly couples where the wife had never obtained a license and the husband had since gone blind--he still drove. Apparently, she told him him when to turn.

"Turn left--now!"

I do not think that my dad would have remarried my mother if she acted the same way that she does when I drive, and his driving scares me sometimes.

I would think that driving blind would be too much stress for someone that old!

Well, I can drive without my glasses, but that is very unpopular with my passengers!

I've never been able to get "instant" feedabck on my diesel--at least not instantaneous mpg becuase of instrumentation issues (there is no fueling info broadcast through the OBD port). I do have the factory installed trip mpg display which I've learned to use. I reset the trip meter before every trip and pay attention to the way it's changing. I also tried various techniques and compared my trip mpg over certain distances. For example, I tried A technique yesterday on my way to work and had 32 mpg by the time I got to that bridge--today I tried B technique and got 34 mpg over the same distance.

So, I'll say that instantaneous mpg is not a necessity per se, but I absolutely agree that you need some kind of feedback.

this should help


seems biggest concentration of optimum efficiency points are at ~1600rpm around 90% load. although not exactly your engine it is very close.

Where do you read what the load is on that chart?
