Alex, well done enjoyed the indepth class on varriable cams, 2 hours went pretty quick. And i dont even have a variable cam, except for my axle back valve which can effect back pressure. Ive been tuning the heck out of my VVE table for a 2015 Z28 LS7, basically maxing out the injectors, more fuel more power, it likes a rich mixture of below .80 lamba to get the most out of WOT. It would be nice to see a video on tuning the Vve table for a NA motor, not just the error calcs but the scuplting the shape to get the most power out of a stock setup. The PE tuning seems to play a big part, I have it coming on immediately at throttle below 75kpa. I have a manual and first gear loves the fuel , so thats my video request, making a Vve table that performs, not the idea of just tuning for 14.7 or lamba 1 and having a underwhelming motor. Thanks.
Another question. When doing all this is it better to say do the cam timing first then spark or visa versa? I now understand all this for WOT which is the optimum power tabs for spark and cams. Now how about tuning for drivability in low end to help partial throttle stuff? Would the same thing work as in advancing the intake as much as possible in the low end? I remember seeing optimum stability was the mapped point called out at idle. What is called out while just driving?
I followed along with my laptop and tune files from GM 4cylinder vvt and under wot cam timing , there are no negative cam angle number available. Are GM cam angles referenced differently than the coyote ?
Every engine management platform has slightly different parameters. Not every platform will have the same settings. You may not be able to go negative, or it may start out in the negative area.
I have 2017 charger rt cammed dyno tuned on 93 straight pipe no cats I just added high flow cats threw a code p1eoa any ideas if that a tunning issue ??
I have a c7 zo6 corvette. I have spent a bit of time on this and injection timming. My car is obviously superchargerd, just having variable intake makes big power feeling. Im about 10 degrees around 4k to 7k than less in lower rpms. Question, does timming need to be adjusted after changing cam advance? Thanks keep it up!
If a tighter LSA makes more power NA, it will make more power under boost. Can anyone prove with back to back dyno tests that a wide LSA blower cam with the SAME specs makes more power than a tighter LSA NA cam? I know what the results will be. All that wide LSA blower cams do is help idle and give up low end torque and HP. Some say a PD blower needs the wide LSA to reduce the low end tq. What??? The whole point of the PD blower is the instant tq. Thats what i want otherwise id go turbo or centrifugal
Blah blah blah. Stopped playing around 20 minutes in. Couldn't take it any more. I hate it when ego takes over from good teaching and instructors blah blah blah to much and confuse themselves and give false information. For the record and for anyone that was confused. Total valve lift is derived from the cam lobe lift multiplied by the rocker ratio and therefore is not fixsd. Change the rocker ratio and you have now changed the lift Combustion is not a stroke, it is a chemical process and it's effect is the POWER stroke in an internal combustion engine.
@@slopoke22 yes I tune, daily and there is plenty off good info available without sitting through nonsense. I mean if your here to learn about tuning did you really need a lesson on how the 4 stroke otto cycle engine works. If you do then your getting ahead of yourself and should stick to doing an oil and filter change because your not ready to tune. Perhaps he could do a video on oil changes. But you would probably have to sit through the whole refinery process of making oil before he got to jacking up the car and removing the sump plug. Dont forget the oil drain pan or your gonna make a mess. Blah Blah Blah
@James Ross I agree just sayin atleast there is something. He may say a few words someone needs. I agree he basically just being a squirrel and talking but atleast he is tuning it just have to forward through the forward lol
Thank you for such an informative video. Can’t wait for more. Keep up the great work.

Nice Video... Without a Dyno can you measure airflow increase as a measurement?

When testing power gain from intake vvt. Is it possible to advance too much and damage engine?

Good info - appreciated the class.
So On the same car with a centrifugal supercharger setup are you gonna wanna open the intake valve sooner in the higher Rpms or about the same?
Awesome info, thanks for sharing/ teaching.
Great info. Thanks.

all i want to know is how to delete the vvt in hp tuners for 2010 L99 camero
Hptuners dod delete and active fuel can be disabled easily

Do you tune? Atleast there is a something out there to listen to and maybe help with a certain situation you may face.
