Tuning my FP Green for 3-port (and 1100cc injectors to come...)

So with some help initially from Golden and then some help from Hollywood to get my AFRs better in check, I was able to come up with the following table. I also even tried re-doing the table from scratch, but this produces the best boost early on in 3rd gear for me.

The only change I plan on making is bringing up the WGDC #'s above 5000 to raise the boost a bit and prevent it from tapering as much to redline.



And then here is my fuel map. I believe it is a bit rich right now - at least it seems so from what Hollywood helped me tune to earlier. So I was thinking about leaning it out a bit, but I was wondering if Merlin's guide is correct in the statement that you want 12.3 - 12 during spool up (which I am not sure when that period is exactly or how to tell), and then 11.7 - 11.9 at peak boost, and then taper to 11.5 by 7000 RPM.



I was also planning on setting my crossover to 75 per Golden's suggestion and then starting to work on 4th and 5th gears by dropping my WGDC there since I am hitting 28-29 PSI of boost in those gears, which feels a bit high.

Here is my virtual dyno right now based on this:



Oh, and my 1100 cc FIC injectors come today, so I plan to install them using Merlin's guide, Method #1, and then tuning the AFRs back in.

Anyway, logs below, wanted to see what people thought of this so far.

I'm curious why you aren't increasing ignition timing in a linear fashion? Looks like you are go from 15* at 6k and then dropping to 13* at 7k.

My guess is to combat the sensitivity gain change induced knock sum's that typically occur at 6,500 and up..... Deff looks like it is neutering the power above 6,500.

In all honesty - the timing map is mostly from a previous tuner and I am trying to figure it out right now. I haven't even touched it yet. Been messing around with MIVEC today.

Here's my current timing table, but I'm not too sure where to start. Should I essentially continue increasing the timing advance until I see knock in a linear fashion as mentioned and then retard it until the knock ceases in the areas I encountered it?
