and I sall it has flat shifting (they call it zero lift shifting) ability. pretty cool, ive never seen a factory car with that feature.

what the **** is zero lift/flat shifting

the car lifts for you because of its electronic throttle? whats the difference?

wasn't that fire-breather shifting without the clutch?

SamS

Yeah the announcer said he only uses the clutch when moving the shifter across the gate, so he's slamming it from 1-2 and 3-4.

flat shifting = shifting while haveing the gas pedal floored. The car keeps the engine at a certian rpm when you do this to keep the turbo spooled.

its really flat shifting with anti lag on the HHR SS.

Doesnt the engine just cut ignition? thats how it usually works for the drag guys.

i assume theyd cut fuel not spark....

Niklas

Wouldnt this be quite dangerous in case of any lingering gas?

edit: looked around a little, at least the UTEC standalone uses ignition cut, not fuel cut.

THeres no gas if they cut fuel.

Niklas

thanks for clarifying
I suppose i was thinking in terms of nitrous, extra injectors, manifold mounted injectors.. that sort of thing

Not every car has the injectors mounted in the head.

Either are ours

Has anyone here implemented flat shifting with their megasquirt?

pumas FTW

Well, anyway, there is a strong possibility that there is going to be some fuel in between the injector and the inlet valve.

knock knock.. whos detonating?

Thats why fuel cutting rev limiters are bad mmmkay.

remind me of my replicats, but i would love to have them in that color

I always thought cutting spark would be safer than fuel in case the fuel cut comes during and injector's cycle only adding a dash of the required fuel

Yeah, its fun but the tranny does not like it too much, but then again my 5spd has been abused for 100k miles.

would you rather cut fuel, cylinder sparks and nothing happens

or

cut spark, injectors fill camber with fuel, then when you ignite again you backfire and blow flames out the tailpipe like an *******?
