Well if it is an emergency case you're sure to crash, then slam on brakes, throw to first gear, pull the e-brakes and cross your fingers.... your engine is already a goner but hopefully you might have little better chance of living.

 

this thread is dead. i can see why.

 

I feel ill when I read this stuff, search and take a driving class.

 

lol, that should have a disclamer saying please do not actually dothis. Its to be done by proffesionals only. haha

 

Coasting, braking, or sitting still while the car is not in gear is illegal in most states.

The reason for this is because you don't have control over your car. If you NEED to accelerate to avoid something, you lose time because you have to search for a gear. If you NEED to brake hard, you run the chance of stalling the car since you aren't in a gear. If you get rear ended and knocked unconscious, your foot will come off the brake and you will roll through the intersection, being at greater risk.

In addition to this, if you use engine braking in conjunction with regular braking, your brakes will last longer.

To the OP, you should downshift and speed match your RPMs as you brake. 3rd gear will be the one doing most of the engine braking for you. When your RPM's are below 4000 in 4th, clutch it, blip the throttle to speed match and downshift while continuing to brake.

 

But it all depends on traffic, speed, and need to slow. You can save gas if you let the R's drop to say 2K if you look far enough ahead. There is no need to stop for a light that's going to go green you can coast in gear. It's all about smooth.

On another note it's funny though one of the first things you learn in a high performance driving school is that you don't use the engine for braking it's there just to drive you forward.

 

Huh? When you're off throttle and above 1.5K RPM, you're in fuel cut. You won't save gas by idling versus downshifting and engine breaking.


We're not talking about high performance driving. We're talking about street driving and normal everyday braking.

 

Either heel-toe, or just rev-match as you downshift.... Or don't downshift. Then this won't happen. Either way, you gotta match your revs.

 

Start braking hard, Heel Toe-Rev Match downshift to 2nd gear, then while the whole time uve been braking, use the engine by using the clutch to help slow u also. then clutch back in when ur about 20mph, and rely only on brakes.

 

brake, clutch and neutral...

 

do you have a wide band? if so take a look when your off the gas it's not at 20.9 O2.

 

You're wrong. I used to think the same way you did until about 4 years ago.


The injectors do get shut off during deceleration - check their duty cycle. It's called DFCO (decel fuel cut off) and unless you're running anti-lag almost every EFI manual transmission car has it. The duty cycle doesn't start up again until the RPMs drop down to somewhere between 1200-1800 RPMs depending on engine temps, RPM drop rate, engine size, etc.

The Mitsu service manual for the 3KGT talks about this, and if i look a bit longer, I bet I can find some stuff on here that shows the Evo and DFCO.

 

do you have a wide band?

 

Nope. This Evo is still completely stock. However, just because I don't have a WBO2 doesn't mean that I am wrong. Ask around about DFCO and you'll see what I mean.

Anyway, back on-topic.

 

I f you had a WB like me you could see if you're right or wrong.
