Need some help with Calc VET

[Supercharged111]

Here's my illustrious tune. Not perfect, as I recall I either lost time or interest when tweaking the timing table last.

B3608 is supposed to be the delay before PE "becomes active",
B3609 is supposed to be how fast PE "become active".

My understanding is B3609 is how fast PE kicks in once it has enabled.

I have not noticed B3609 adding any delay, but I like to not chance it.

Thanks for the intel

Click the +.00 button to increase the decimal digits (precision).

Found it. Thanks

Wow those numbers are higher than what ive been able to run so far with 93 Octain.

Maybe im miss interpriting the retard and its not acutally due to knock but due to the extrapolation between the 2 tables?

Check me and see if im horrably wrong.

The KR PID is different than the interpolation between hi/lo PID. Can you post a screenshot of your timing table? My old EFILive didn't open the .ctz.

So what are you saying that if i see .2 or .3 on that table that i shouldnt pull timing?

[Supercharged111]

Well it depends. How many samples did you get on that frame? And do you check the peak value in addition to the average value? Sometimes I get a rogue KR spike of a degree or 2 that averages out to a couple of tenths on a frame that maybe got a dozen samples. I personally don't worry much about an isolated incident like that but then again I'm not a professional so I welcome feedback on my methods. Your timing table is much too slow to bring in total timing, you'll gain a lot under 2000 locked in OD by bringing it in sooner. The other reason you think my table looks so aggressive is because I zeroed out the PE timing adder B5908. The conditions that add that timing involve PE fueling anyway, so I just incorporate it all in the high timing table. I haven't noticed any KR at atmospheric closed loop so for me it seems to work nicely.

So now Im Just confused.

So am i wrong for dropping the timing on those cells that have a value other than 0 and blending...

Im open to trying to run your timing tables and see what happens.

Just kind of lost now.

I can't believe you're getting KR where you are with 93 octane compared to mine. I realize every motor is different but damn, premium fuel and headers should make a motor want a lot of timing. Again though, are we viewing peak KR or average KR and how many samples per frame?

[HellKnightHicks]

On the left is average values on the right is the number of samples.



Am i doing something wrong?

Should I disable PE?

; a correctly timed engine produces the most horsepower. An engine with timing too late (retarded) will have a low idle vacuum, have slow throttle response, feel like a turd at low RPMs and will run hotter than normal. An engine with the timing too soon (advanced) will have a high and erratic vacuum signal. It might have a snappy throttle response but it won't pull very well under a load, and it will have pre-ignition (detonation) problems, sometimes called "pinging", which will certainly lead to either a blown head gasket and/or serious piston damage. It will also idle rough, like it has a bigger cam than it actually does.

I guess im all alone here now... Ive chased everyone off....

Im still tweaking the table some for spark very happy with the results thus far.... Wondering if a lean cruse isnt possible since ive ditched the EGR. Tempted to put the EGR back on honeslty.... Mileage dropped this last time by 3 mpg.
