every engine is different and their combination, I have the crower setup in my car right now, and you will see the CEL light flicker pretty fast from 1800-3500 or so... this is not sparkknocking.. however if you did nail it say at 2800 you could hear a bit of sparknock, but not much, but lately my map has much improved.
the map crower has given out has columns 8-9-10 pretty well mapped for the design of the cams (fuel wise) because it's tuned for full power, the lower columms need much rifinement under part throttle in open loop. but it's nothign a couple days of driving can't tune almost perfectly. it takes time to do all the cam angles but it does cure alot of hesitation issues and driving issues.
mostly from openloop to closeloop transitions. because even if you let off the gas, your car will still go in closedloop for a couple seconds and if your map isn't tuned right you could see fluctuations.
for the vtec crossover point, you problably have a rich spot and ti's acting up on ya, try putting it higher until tuned and you'll see it fade in...
tunning these cams over a thread is very hard.
I never had any issues with mine, and your setup is about close to what was done with the basemap, so i'd say it's time to drive around and tune it... for all the flickers you would see with the cel, disriguard it, if you hear knocking in the engine bay, then act upon it.
my vtec cross over is at 5300 but it could be much lower. if your low cams are tuned right you'll notice that the baselobes make great power, and you don't need a early vtec. ti's all about the tuned VTC.
since my map is tuned for a 99mm stroke motor my ignition values would not be good for your setup.
