Weird cruise control / mpg issue.

And there's no lights on on the dash nothing. Very strange

 

That could be but I would think just adjusting the TPS the little bit that you can The computers would make up for the rest of it or show the cruise what it needs to see so I guess you use the cruise a lot I don't much. I'll have to try this tomorrow

 

Interesting, I didn't think the TPS was supposed to be adjusted in the field.

And, why did you have to adjust it?

 

I use CC a lot. It really helps on mpg. I don’t drive in mountains though.

One thing I’ve noticed is that if I’m in CC mode and the engine is on with power also coming from battery, and the battery is pretty full, if I momentarily that is for a second or two, disengage the CC with the lever then restart the CC, the engine turns off and the car goes full EV mode and the engine stays off. Seems like a software glitch.

 

Any chance you have the car in "B" instead of "D"?

 

That's really good call actually

 

CC is supposed to work only in D. B cancels CC.

Though when I'm using CC downhill, the ICE generally doesn't stop either, but spins up in engine braking mode. But this strongly depends on slopes and speeds.

 

Bad vacuum noise could cause a whole lot of nonsense you need to definitely find out why that is A lot of sucking noises is not good and supposed to be sucking on something and you're not really supposed to hear it so that could make idle go up etc and then the computer's trying to compensate for that and oh God it sounds like a real circus.

 

In my early celiacs I think we had adjustment on TPS very small scale. Played with it once put it right back.

 

That is probably way overkill. You only really need to remove the filter housing and the MAF sensor then clean the throttle body throat and throttle plate with some throttle body cleaner and a soft brush followed by a wipe with a cotton cloth. No need to disassemble more than that.

It is for getting the TPS adjusted at the factory. It is not supposed to be messed with after that.

If by that you mean the 50 (0r so seconds of warm up (stage 1) then yeah the timing is set so the engine runs hot (and very inefficient) to warm the engine quickly. While that is happening the car, if driven, will predominantly use the electric motors for propulsion.

 

It's just for a very short time and then whenever the timing gets back normal the plug self clean and all this and that kind of nonsense in a normal internal combustion engine anyway I would hope in the one N z still. Not sure about the Gen 3 and it's Atkinson cycle business it seems to run on its own puke regurgitating that puke and still running.

 

Drag increases exponentially for each mile-per-hour increase.

Redo the experiment at 55 MPH for a more impressive MPG. The sweet spot for the Gen 2 is somewhere around there.
