WOT Acceleration

Has anyone else noticed, but Wide Open Throttle doesn't appear to be as quick as partial throttle? I first noticed this when letting up and the end of some timed runs, the car seems to accelarate as I was lifting. Upon further investigation I was able to confirm that modulating the throttle results in better overall acceleration numbers that just gunning it.

I've had other cars where this effect was perceptible also, but not to this extent. Typically the modern ecu goes "open loop" under WOT conditions which means a rich mixture, but this MAP seems richer than most.

Anyone else confirm?

I noticed it yesterday. At full throttle it seemed to hesitate just a tad bit, and when I backed off a little, it seemed to "catch" and what a launch! :-)

You know the car is very deceiving. Sure it doesn't have the torque for a fast standing start, but if you are in the right gear at the right RPM range, WATCHOUT!

Besides I noticed that the true advantage of a Rotary becomes apparent in a stoplight racing situation when you are shifting once for every two shifts the competition is making, thanks to the 9000 REDLINE!

Is the same phenomenon observed even after a fair amount of miles racked up on the odo?

after 3500 miles, I'm still getting tailpipe carbon deposits after only a few miles from a very thorough cleaning.. ie.. it's still pig rich..

do you think changing exhaust to hks or greddy when they come out will stop the black snot

I think you need an exhaust catch can for the black snot, lol.

I'd be more worried if changing the exhaust stopped the carbon build up.. it'd mean that it's getting plugged up elsewhere in the system.

The only thing that'll stop that 'snot' is leaning out that pig-rich mixture..

Excellent point, and shows what appears to not perform on paper, may in practice, be just what DOES work when dealing with real world situations....
