Engine braking

[Gav]

Hello,
Hope all well.
I would like to increase my engine braking as trying to fine tune.
I have efilive and understand may be the throttle follower cracker tables

When if accelerating and i come off throttle i want to increase that braking a bit more as having to brake harder at the moment but dont want severe engine braking if shifting up through gears, so is this the delay or decay23969?
What exactly should i try?
would like a bit more less cruise control in all speeds but more braking at higher speeds after a delay.
Have attached my latest tune COS3
Tried posting in LS1techbut no replies so far..

Hi Gav,

I’ll spark up my laptop later on and have a look at your tune file, throttle follower affects overrun (so cruise effect), you can also play with DFCO to affect engine braking.

Try retarding the spark table(s) at loads (g/cyl) correspondin to closed throttle.

Also, if you have AT, set the TCC to remain locked on closed throttle coast.

Gav, if you get too close to zero then you’ll pop n bang on overrun (a giggle for a while ;-))

Hi,
How much should I retard the timing? Running around 37 in those overrun areas atm, gonna try 30? Or do I need a lot more?

Er, where did my post go!

10 degrees

Short version!

10 degrees will get you the pops n bangs (sorry, didn’t read the thread as it popped up,on my iPhone!)

Hi,
Reduced to 30 degrees in those areas helped.
No pops yet though....
