FYI.............
After settling into the thought of me being essentially done refining my tune file, my attention turned to the fuel injector reference setting (this sets the injector timing's EOIT--end of injector timing--modeling point to the cam's intake IVO timing point) in my tune file since I've installed Lunati VooDoo #21270700 cams in place of the stock OEM cams. Using the advertised duration-based cam timing points (better match to the cam's 0* timing that VCT uses to determine any cam timing degree change from crank timing) of the stock cams (IVO @ 15* BTDC off camshaft 0*) I find that the 345* crank setting used for injector reference fits (injectors will fire into the back of the intake valves while still closed but right at the point of opening) to promote fuel atomization\swirl into CC off hot intake valves) thus any VCT retard angles from 0* the PCM will use to offset the injector crank angle reference of 345* to maintain this injection to IVO pattern thruout the RPM range.
None of this was covered in the 05-10 Ford Mod Motors HPTuners training videos.........
When I ran my Lunati's thru this same check, I found that for these cams to be realigned to fit the stock injector timing modeling, the injector reference IVO crank angle needs to be set @ 330* in tune (Lunati's IVO @ 30* BTDC off same camshaft 0*), but I find this to be set in my tune file at 349.5* crank angle (4.5* later than stock but also puts the injectors to be firing into already open intake valves--19.5* past the 330* IVO point--instead of firing into the back of closed intake valves at the point of opening as the stock cams were modeled).
This got me to thinking as to what effect on engine performance this is causing.....especially low end TQ, as from all the research I had done suggests that this has the largest effect on low end TQ output & emissions but hardly any effect on mid\high RPM HP\TQ output due to high engine RPM's.
So, I reached out to Jeffery Evans @ Evans Performance Academy to give me some insight into this. Got reply back from Jeffery explaining the traditional reasoning why OEM's (GM, Ford, etc) typically time the injector EOIT to the cam IVO when using port fuel injection (which in general he validated my reasoning of fuel atomization\mixing as to why Ford timed the injector pulses to the cam IVO point) & that is the general pattern to follow but he also stated that the OEM's use other criteria as well (ECT, CC temps, IAT, etc) in determining the final cam IVO crank reference for injector EOIT so to be aware of this to not think this is a set in stone kind of model. But I also noticed in the injector section of the tune file there is a map that references injector timing vs ECT but the map is zeroed out which disables it (also found to be the same in all bone stock tune files as well so HPTuners doesn't provide any access to any of the Ford back end control (opposed to GM HPTuners which gives a lot of access to all this stuff thru GM PCM's) outside of the injector reference IVO crank angle setting & absolutely no mention of any of this in the Ford specific sections of HPTuners forums until 2016 MY when HPTuners provided access to Ford's OVI (open valve injection) algorithm in the later Ford PCM's......which doesn't do us SO PCM folks any good.
So I'm tempted to reset this in my tune file to match up my Lunati's IVO point to the injector's EOIT point mimicing the stock cams modeling to see what comes out of it. I've also looked at some other folks SO tune files that installed aftermarket cams & haven't found any that made corrections from the stock injector reference IVO crank angle setting so all are firing injectors into already open intake valves (all aftermarket 3V camshafts have GI cam advance greater than stock thus cam IVO points are ahead of the stock cams so this is a common issue in the 3V tuning world).
Maybe there's a good reason for not correcting the injector reference IVO modeling to match the OEM modeling purpose w\ these 3V's but I can't find ANY Ford tuner that has given any info on why not to correct this to match. My car runs good w\ these Lunati VooDoo cams having the intake valves already open when the injectors start injecting fuel into CC's, the cat CE ratio results are looking fantastic & I don't get any raw fuel smell from exhaust due to excess fuel scavenged thru CC into exhaust during OL, so it appears that there isn't any operational issues from it but I'll always be curious as to the effects of low end TQ gain\loss unless I test it.........Ford had a reason why.
I even looked at an OEM tune file from a 2007 Ford Sport Track truck (4.6L 3V iron block w\ VCT) that has this injector EOIT reference IVO crank angle setting set @ 360* or TDC or cam IVO @ 0* (don't have any info on cam profile used) so not all 4.6L 3V engines were set up the same even though all used port fuel injection w\ CMCV's & VCT for EGR as well.
Interesting issue & discussion but in the meantime, I'll leave all this as set until I get my Pro Link & WB controller installed as there doesn't appear to be any issues from an operational standpoint from the injectors injecting fuel into CC's thru open intake valves........
PS edit--Forgot to post this picture of an engine to crankshaft cam timing wheel that helped me in figuring this stuff out...........
