As in hardware vs software I’m assuming?
generally a tune is changing the fuel map or timing of the engine similar to how the engine's max power increases changing the fuel from regular to premium. engines are regularly tuned to remain in a safe zone, but tuning can gain power, but it also reduces the margin of safety, which may compromise engine longevity.
This. You are the tune. Keep it at the RPMs you want it at...
eco boost is nothing than another way of saying turbo charged... when the engine is running in low stress situations, it is eco---- when it needs to exert power the boost kicks in... (oversimplified explanation)...
Well, yes and no. You are the transmission, but you can’t get around the rev lag without a tune. I miss a mechanical throttle, but it’s nice being able to tune an electronic one to the drivers desires. Getting rid of the rev lag almost makes the electronic throttles perfect.
To be honest, this is way over my head. Once I know a vehicle I learn the shift points and don't need the clutch except for take off and stopping. That's old school mechanical, I know. I thought that if you kept the revs up the turbo would remain wound up to an extent? Please dumb it down for me...
Rev lag is like shifting without ever letting off the gas. Using the clutch softens the blow, but it’s like you never got off the throttle while shifting. A typical smooth shift in my Tacoma takes 2 seconds. A one second shift is pretty harsh and a shift without the clutch is like never letting off while shifting.
That was a well-done video. It is a skill to explain complicated processes like this in simple terms and that guy did it very well. Thanks for posting!
Slightly off topic, does your Tacoma rev hang in all gears or just certain ones? Mine hangs only on 4-5 shift primarily when I'm on it entering freeways and north of 3k rpm wise off the top of my head. It's not noticeable shifting through everything else. I also have a 2nd gen so maybe if you have a 3rd gen with newer emissions that might be it.
