I came across this page on how to setup the A'pexi safc and I know on the Jdm 2j it uses a map sensor instead of Maf so I have it set to pressure. Now when it comes to TH point, graph scale and NE point are they the same? Just want to confirm this, thanks



A'PEXi S-AFC Installation


First start off by Resetting the AFC. Many have often complained that their AFC does not show full throttle(%100), regardless if it is brand new. Go under [etc.] and press NEXT~>. Confirm "YES" when prompted "Init. All?" and press NEXT again, Now turn the ignition OFF and then back ON, and the unit should now be reset and ready.

Next enter the following basic settings:

-Go to [main] ~>[setting] ~> [3. TH-Point] ~> [Lo-94, Hi-95]
-Go to [main] ~>[etc.] ~> [1. Sensor Type] ~> [1. Hot-Wire] ~> [in-12, Out-12] ~> [in-1, Out-1]
-Go to [main] ~>[etc.] ~> [2. Car Select] ~> [Cyl:6, Thr: UP]
-Go to [main] ~>[etc.] ~> [3. Graph scale] ~> [Ne = 7000rpm]
[Ne-POINT = 3500, 4000, 4500, 5000, 5500, 6000, 6500, 7000]
[Dec. -Air = NOT USED, unless you want to use it to compensate for venting your BOV to atmosphere]

My usual settings:
Sensor=PRS in1/out1
TH point 5%lo 55%hi
NE 1000-7000 if you're comping for bigger injectors. split 4000-5000 or where ever you get peak cyl pressure into two 500 rpm cells.

That little guide looks like its set up for a stock US 2j. I' still dont get the 94/95 th point though.

What size injectors are you using?

Thanks man, yea I was wondering that too about the throttle points. It just didn't make sense so I just somewhat ignored it.

I saw on a post here to use 68/69 for throttle points but yea.

I'm running 550cc off of the USDM 2j supra, and thanks again for confirming that for me..
