Re: dsp best econ tune bad
The 91/93 tunes have problems with knock retard. Can't tune it out with the handheld, either.
The canned tunes, much like the stock tune, has a nasty WOT Delay that delays the triggering of WOT fueling. On most trucks I or David either tuned or watched logs for don't get true WOT fuel until after they hit 2nd gear, which, between running a ton of timing advance, targeting 14.7:1 AFR in closed loop in WOT, and the load of a 4800 lb surging forward after banging the 1-2 upshift, trigger KR that is off the charts.Even when WOT fueling is finally brought on, the KR takes time to be pulled out (for timing to be ramped back in).
In CMR we have control of this delay- and do so by removing it entirely.
Due to my workload, please do not PM me as I do not regularly check my PMs. Thank you :)
