I don't know of a single dyno jet in my area, stm,innovative, efi logics, andprobably more uses.the mustang. It's not just.a.correction factor in a software program, its a local representation of what's commonly available most.cases. just my thoughts. Im gonna POP the cam cover off and scope that out real quick.
Also, "printing out" a dyno chart in both Dynojet and Mustang settings is not hard with VD

I did use the mustang correction at first in a different thread, but I caught flack on how it wasnt accurate. So when I posted my new thread I posted with the 1 factor, again I get thats not right. I give. llol...
Anyways heres my mivec map. I have dialed some of the lower rpm mivec back because i was suspicious of it causing knock, and compressor surge, which was wild at one point with a lot of mivec. i started with a JDM map, and just decreased to a few more reasonable numbers in the low RPM area, seems to work fine, and in my findings of the MIVEC tuning thread I came up with no logical solution for a cammed car. Other than, the cams already flow a lot, and no correllation to mivec for me. Ill keep playing with it, and once I get the WHOLE tune straightened out it might become more clear. I do get some tip in knock 4000 RPM and above, considering where my mivec map looks like it starts to go at max= 4000+, so maybe theres still a link there. other than that, Ive been massaging my timing map in the mid rpms 100+ load.

heres where I left off tonight. 22 psi, no funky boost creep this time(well, a little). I didnt change any thing in the top end timing, just fuel. Im undecided on where I will leave the fuel, @ 11.5, or 11.0 from here. i kinda want to see what 11.5 does across the board.. the dip is coming out, im sure theres more to that dip than timing and fuel (mivec?) lol.. Ill get there!

Off, I was hoping to be able to use it to my advantage when i learn more of how it should be used. Until then, its off 
.
Ill probably do a few more runs tonight, bring the AFR to 11.5ish acrosss the board. need to do a ton of tuning starting at all the various rpms, so that i can have the car safe enough for autocross aswell.

yeah im just stabbing in the dark. been doing HOURS of reading while my evos away for the winter so i can take on the tuning task this spring.
im scared shatless, but your results are wonderful.

fwiw, I have done over 100 revisions to get me where I am, and its still not really that great. There is a few drivability changes that need to be made. Just prepare your self and dont skimp on the tuning tools. get a wideband with a lap top connection, either thru the ECU mod, or serial logging. A lot of things will leave you shooting in the dark, and IMHO that is the worst possible situation to be unsure of something. research and research.. I come across things I dont know, search, read about it, and sometimes the question doesnt get answered to you , even if the answer was there. Its kinda like you have to know some steps ahead to get the ones behind kind of thing. Thats where taking your time and self control to baby it around in the early stages comes into play . Alas, if I can do it, you sure can.

Use more smoothing. Most of the charts you have posted need more smoothing.
Also, take multipule runs and run them so VD so you can make sure the power is consistent and not a one-time fluke.
(not saying your run(s) are flukes. Just giving tips to help you get the best, accurate results from VD)

Smoothing as in map smoothing or results smoothing in vd ? I have been paying heavy attn to the 80- 180 loads so there isn't too drastic of a change. I like the fact that its a rolling log of my gain in power and knowledge lol..
Can you make vd average multiple runs or is it limited to overlaying multiple ?

best I can do right now. I might have smoothed a little too much into the transition between 100-140ish starting to get a little knock there and AFR's look inline. im guessing I took just a smidge too much out. Although it doesnt necessarily reflect too much in these I wouldnt think.
The only thing changed between these two is some of the timing between 80-180 load. I am hitting approx 250ish load with most of these logs max
the timing map is just an idea where Im at in the WOT areas, and what I am about to try in the lower loads/transition area. just got a bunch more lovin

And VD cant average multiple run. You just want to take multi run and make sure the power is consistent.
