Default Can't believe I'm doing this... I have a question about AFC Hack. SEARCHED

I've searched... and searched. There are approximately 12,183,123,890 threads about the SAFC, but it seems that every single one deals with boost. I'm interested in the sans boost tuning capabilities of the SAFC.

Let me start by saying that I'm not a fan of the SAFC. I've never liked them, and everytime I hear about turbod Honda's with "the Hack" I cringe... But as much as I distrust these devices, I find myself in a bit of a pickle.

Before I continue this babble, let me post my setup- (Not actually in the car yet, but will be in a couple of weeks... got the parts, but don't have the time. )

1990 CRX Si

D16A6
Freshly rebuilt (all bearings, gaskets, rings, etc.)
P29 Slugs
Z6 head gasket
0.01" milled off the head

Aggressive cam (Haven't been able to make a choice on this yet. I've heard good things about the Delta 272, Exospeed's stg. 3, and Crane's 251-0012 and 251-0016. I've got some more research to do.)

62mm TB portmatched to Z6 IM
I/H/E
FPR
AEM Cam gear

This setup will have a Compression Ratio of 11.38:1. I will be running 93 Octane.

Though I don't consider this build to be extreme, it is definitely above and beyond what would be considered mild, and I feel that it's probably going to be necessary to get it properly tuned once it's in. I guess what I'm attempting to do is find out if I can rid myself of the expense and time of doing the OBD1 conversion and getting Hondata and blah, blah, blah... I don't wan't Uberdata or Crome or any other free program. I've used Uberdata in the past, and though it's a great program, I don't have tuning capabilities, and all it was good for was a boost basemap. I plan on taking this new build to a professional to get it tuned, so I need something he can tune with. And this is where the SAFC comes into play...

Is the SAFC capable of tuning a moderate all motor setup such as this. I'm talking full dyno tune, for good A/F ratios and a few extra ponies, not retarded guesswork assdyno tuning.

Wow... that was rather longwinded. Sorry. If anyone has any input, or better yet, firsthand experience with this, I'd appreciate the help.

Oh, and excuse any errors. I've been up all night researching this mess... it's now 5:03 a.m. and I think I'm actually asleep right now...

I would like to know more info on this matter aswell.
I am in the prosses of building almost the same engine.
One question though. What is the benefit of using the Z6 intake over the stock A6?

Well, I haven't actually been able to confirm this, but supposedly the Z6 mani has a little more volume in its plenum and runners. To me, they look the same, but who knows what they are like on the inside. Honestly, the only reason I went through the trouble is I happened to have a spare Z6 mani just layin around. I know a lot of people like to use this mani swap to get rid of thier firewall mounted MAP sensor, but this didn't really apply to me because I was planning on using a B-Series throttle body regardless.
