A brief description of the new approach would be great, if you're willing to type it in. (If nothing else, it would raise the value of this thread by a few orders of magnitude.) What I was describing is the method used by many people with things like DSM-Link on a 4G63. We retard the timing and dump fuel on shifts. Poor-person's ALS. It didn't work well for me, so I stopped using it after a few months.

 

i am not a tuner, so i wouldn't go "details" which i am not certain.
but with these new ecu's they do the opposite, cut a fuel vs the old ones. so that is a reason why the als doesnt make that much damage like they did before. and that is why they a bit quieter.
when you see flames that is either old ecu maybe engine problem or not a proper tune.

the new type of als and launch programs:

 

Hm. Sounds like they're using the heat of going lean, then. But I should not discourage your attitude of not discussing things that aren't fully understood, as that's the attitude the internet needs more of these days. cheers

 

my understanding they do timing and fuel cut vs the fuel dump.

this the time when they didnt had a restriction neither als:
