So back to the topic at hand...does anyone want to share the settings they've used? Looks like initially we are to set the sensor type to Hot-wire, IN/OUT to 01 & 01, cylinders set to 4, throttle sensor type to the upward arrow, and I used knock sensor 1 (the grey wire). By the way this is for the GS4. Now beyond the initial setup, I don't have much to offer as I haven't gotten a chance to get tuned yet. I'll probably pull off the SRT ECU, plug in the SAFCII and run on the wideband sometime this week. Any tips or advise is appreciated.

 

I've checked out the online S-AFCII manualand I believe the sensor sentting for the GS400 is 13IN/13OUT. it shows the sensor type as HW-13 for the GS400. May be someone that has installed the s-AFCII can confirm that .

Has anyone put one on the GS430 yet? I've searched and it seems that they are all on the GS300/400.
The ECU wiring is different than the GS400. I've been trying to figure out the ECU wiring with the wiring sevice manual but I've almost have it worked out.

 

I wish someone could confirm this. The documentation (online vs. printed) has discrepancies. My printed manual says MOST vehicles use 1IN/1OUT. It also says to set the cylinders to 4 (not sure if this is correct). Another bummer is that there doesn't seem to be a diagram of the US 1UZ-FE ECU ( I used someone else’s diagram on the forums and it appears to be correct). I have a 400.

 

13 in/out is correct. you se cylinders to 4. I already posted directions for the safc ii on a gs400. Might want to do a search.

 

Did a search, I didn't find too much info, actually NOTHING specific in your install posts. Maybe I'm not finding the correct posts, these have no useful info:

This where I posted some directions.

Use HW13 in and out and set cylinders to 4.
E-mail me and I can get you the wiring diagram. I moved servers so the link the pic is dead right now. I'd update it but it's on my work computer, not my laptop.

 

will installing the SAFC II on a stock car do anything? besides looking cool...? lolz

 

I have it installed on my car right now. It isn't set to modify anything, just monitor...yes it looks cool. So yes, install it first then go to the dyno and tune it.

 

It'll help a little on top. It's a little rich up there but perfect everywhere else so it will ONLy help top end a bit is all.
