These links aren't working atm. Is there an update to them? I am close to installing this in SAFC mode and had a couple noobish questions.

I'll add links and information to this thread when I can.

Anyone have experience with the "boomslangs" for this? The wiring doesn't seem too bad without it but curious of pros and cons.

I bought the standard extension boomslang and soldered it all in for plug-and-play. A lot of money for nearly nothing, but I wanted to keep my harness good for when I sell it.

I feel the same way looking @ it. And, car is already modded way beyond return. Still, will use quick connects for splices with male/female to allow easy removal/return to stock. Save $ for speed density set up.

I used the below link and the quick setup guide to install; Version 4.4, relatively stock, w/ walbro, AEM inline uego (tapped into), no MAP sensor.

I wired it up as reccommended, however, I am only setting it up for AFC at this time using the stock MAS. The above link has a questions and answers, where TurboBob says you can do it, with certain settings:

F-out mode should be set to Zero. Had to choose 1 (DSM 1g) or she stumbled & otherwise ran like crap @ idle. Also, there is no zero option; but a fuel pump control option.

V-Out1 mde set @ 101
V-Out2 mde set @ 100 OK.

Mainscale set to zero - stock 360ccs.
Everything else is set to the quick setup guide.

She seems to idle ok with these settings although slightly rich @ around 13.5.
MP reads 255 when engine is off and on. Everything else (ie TPS) seems to be correct.

Is this okay just to get her running? any glaring issues?

Plan to get the serial to usb adapter and update everything, then start looking into dialing everything in, setting afr tracking etc.

as long as you use the quick disconnects you should be fine. I have had issues repairing harnesses with soldering. The soldering is very stiff and if you pull the ecu harness out a number of times they can break the wires near the joint. Now that I know better I would never cut the stock ecu harness. Unfortunately there has always been someone in there before me...

I removed the front seat to get better access (stock seats are outrageously heavy btw). Had a hard enough time crimping. Can't imagine trying to solder all upside down/sideways..stretched forward etc. Would also probably help if I wasn't such a fat ass!

Got some feedback from TurboBob on Fullthrottle website.

To run AFC mode F In and F Out settings need to match.

Currently she runs, although a tad rich per my SM3 AEM WB readings, as mentioned before mid to low 13s. Cruising is a little richer between mid 12s to mid 13s.

I have been gradually adjusting the main scale to lean AFR and getting some strange results. It seems the NB O2 Sensors are showing a lean condition via the O2 trims. So the fuel trims are compensating for the leaning out of the main scale, so I am still in the rich AFR. I guess I could keep adjusting till she is out of closed loop, is that what is normally done? Should I unplug the NB O2s?.

Not sure if that makes sense to anyone. There are still some sensor/Config/Setting issues I need to work out (WB wiring to MAFTPro not working), so hopefully this will clear things up once it is fixed.

I switched the wire taps for the aem uego & it works on Maftpro now. It's the exact opposite of the quick set up guide(for the aem) .
A quick warm up showed idle close to stoich.
