CCB's VROOOM V.1.0 PE_RPM_vs_TIME Tables
It is important that we maintain steady O2 levels throughout a WOT run and in this tables, I suggest that if you are N/A, I would ask that you start the first column off at 0 and DECREASE each cell to the right by .1 (ie: 0, -0.1, -0.2, -0.3, all the way to - 1.25, etc...). If you are supercharged or turbocharged, the decreases drop by .2 (ie: 0, 0.2, 0.4, 0.6, all the way to -1.25, etc...). I found that on my car, drops of 0.1 were perfect with a 3.4 pulley, but as soon as I put on the 3.2, the drops of 0.2 were needed to maintain an even O2 at WOT. Of course, these are baseline suggestions and it is possible that you will need to touch up the files to suit the performance characteristics of your car based on your needs. It is also VERY important to note that since we are basically starting out from a 0 instead of a -0.5 or so, to drop your BASE_PE_A/F by at least 0.5... as an example, if you were previously at 11.7, you will have to decrease your BASE_PE_A/F to 11.2 for best results. –Open Tuner Notebook-
PARKER, where did you get that tune BTW?
Just out of curiosity, what is your injector duty cycle at peak RPM?
an engine rotating at 6000 RP(M)inute = 100 RP(S)econd
100 Rotations per second means there is one revolution every 10ms
There are 4 strokes (2 revolutions) per combustion cycle
This gives your injectors a 20ms window at 6000RPM to spray fuel.
If you shift at 6500RPM figure ~18.5ms
Might be worth investigating if your only seeing KR at high R's
-A
Cool I'll try that- my 02 gtp has table starting at a POSITIVE number, like .500, adding (leaning) thge AFR at minimum RPM's...???!!!
Injector duties are mid-teen milliseconds, the injectors are sufficient for this build.Just out of curiosity, what is your injector duty cycle at peak RPM?
Will update soon, just been busy with work and my undergrad convocation.
