How does it effect engine breaking?
If the RPM drop fast isn't that helps in engine breaking?

Losing top speed is not a prob for me as well, barely run more than 130km/h.
RPM fast drop actually affect everyday driving as well such as when we release the accelerator pedal and glide forward to slow down. Faster rpm drop means it will be a shorter glide. In a start stop traffic, LCP lower end torque (faster rpm rise) helps but it will also be negated by the faster rpm drop coz it cuts our gliding forward time (no accelerator press). Of course for pedal happy guys, accelerate and press brake to stop harder, repeat, RPM drop will not matter. For FC conscious guys like me, rarely hard brake, just glide forward and slow to a stop, it does affect.
My City with CVT drive actually drop its RPM quite slowly (due to CVT mah), thus it allows maximum gliding time (no accelerator press) while car moving forward to a slow stop. This save FC. After driving City for 5 years, sort of brought this technique to PE as well, tho PE rpm drop quite fast comparitively.
Engine braking of course still require actual braking especially for downhill. Engine braking only supplements our braking power that helps in pulling back the engine to help increase braking power. I also don't know how LCP changes will affect this (thats why I asked abt it) but it was based on comments by fellow City members that have experienced this with Myth LCP.
I'm totally noob in engine mod except for a couple of very minor mod that I've personally used. ie VS, grounding, PC cable.
because the LCP make the enging pulling less inertial force,:
Pick up: engine -->gearbox--> wheel
engine breaking: wheel-->gearbox-->engine
exp: a manual car speeding at 80km/h@2krpm 3rd gear, to slow the car with enging breaking without break, lower the gear to 2nd but due to the gear ratio is higer than 3rd gear so the rpm rise up because the wheel spin the gear and the force will then pass to engin and this is so call engine breaking.
in the simple way to siad accelerate is we inject the petrol to force engin to spin the wheel through gear box, engine breaking is we use the gear ratio to counter the wheel spin by using engine force.
So from other member that has LCP telling us the LCP make the rpm rise faster then we can expect the wheel spin will also make our engine rpm rise up faster during the engine breaking, but in theorically it does not cause lesser engine breaking force, maybe just the fist rev-match bring lesser car chocking feels so some one said it cause less engine breaking.
