That step is not "real". It's the power enrichment routine of the VCM kicking in when Reese applied full throttle. Reese says he needs to figure out why the VCM is taking too long to react.hdflstf said:Jim,
Can you explain the step in the torque curve at 3500 to 3600 rpm. What's with the start points of the curves - why the higher rpm start point on the second set of data?
Aside from that the torque curve really got fattened up. The higher gears must be fun, just roll onto the throttle and you're flying!
Because this is the first SSR he has taken on, he has not yet learned all the tricks he has about the C5s and C6s. He also has to figure out how the torque management works on the SSR program, as we believe it is set VERY conservative.
When I read the descriptions of what the commerical prepackaged microtuners are doing, I am pretty certain that they are tightening shift times, increasing shift pressure, increasing WOT shift rpm, and altering the torque management limits, all sometimes rather aggressively - more aggressively than either Reese or I want to go. BUt, Reese has already tightened the shifting somewhat, and raised the shift rpm, but not as high as the microtuners. The torque management needs more study.
The shifting, the torque management, and the high rpm performance need more work. The low rpm and mid range rpm response is now pretty strong and very satisfying. It's almost like a slot car changing lanes at 60 to 75 mph without a downshift (2200 to 2750 rpm with my 4.56 gearing!).
The sound is a BIG improvement. Had another incident yesterday. A driver in the next lane was gesturing persistently for me to roll down my window. When I did so, he simply said "THAT's what a V-8 is supposed to sound like."
