Brake torque limit

Hello,

What I understood that this table used for like a start from zero or for burnout it's correct?

Also i have other questions in some gm trucks there are high octane , low , base , coastdown , in gear and p/n -- in advance section

But i cant find base and coastdown in my truck why?

I have 2 trucks for the second truck i found the tables and I played with spark to make some popping in deceleration but still looking for some flames it's possible ?!

Thank you our great instructor :)

Best regards,

The brake torque limit table restricts the engine torque while the brake is pressed. This will limit your ability to do a burnout or to launch with maximum torque if you're into drag racing. If you max out this table it essentially eliminates the function.

If you want flames you will need to disable DFCO.

Thank you I got it

and regarding the flames or backfire .. DFCO already disabled and i have strong popping cause of playing with timing it's -25 to -30 in some area's

but how to get flames ?

and what about the 2 tables for coastdown and base i cant find them ?

There's a lot of factors that add up to whether or not a particular car is going to generate flames on over run. In particular it's more common with straight through exhaust systems and it's also more likely when the entire exhaust system is hot. You'll also need to over fuel the engine which on the GM PCM is difficult because you won't be in power enrich so the ECU will be targeting 14.7:1. You could potentially force the PCM into open loop and with an SD tune falsely increase the VE values in the over run area but that's a lot of work that will probably have an overall negative impact on the engine's performance.

The available tables and options vary from one PCM to another which is probably why you aren't seeing the Coast Down and Base.
