Any club members has APEXi S-AFC installed and succeeded with the performance? Every sensors works but having difficulty reading the throttle input for gs400. There were some indicate of throttle voltage but no throttle percentage read. Thanks in advance.

you have to set what type of intake manifold your car has, the GS400 has the HW-13 or Hot-Wire sensor type, and you have to tell if voltage goes up or down in out cars. I dotn know about that one try it either way, but i KNOW its HW-13 dude, good luck

Which wire scheme did you use? I think the T 10a might be correct, I don't know for sure. I'm going to install the S-AFC this weekend and I don't know which diagram to use, which one did you use?

I am putting in a AFC too.

In the booklet it has the Aristo 92-97 as diagram T7-c
Is this going to be the same for my 2000 GS300?
Also what settings have people used with weapon R intakes/exhaust for the most gains? I don't have acsess to a dyno to tune......

v300 told me before that the connectors between US and Japanese Aristos/GSs are different. US models get an extra set of pins somewhere I think. Yes even the JZS-160 and GS300s are different. So harness kits don't plug in. Check with experienced installers before attempting any installaitons. Try XS or A51.

What do you guys mean by "plug" I thought the connections were just "T'd" off the oem wires?

"T" you mean splice?

What I was saying is that, they sell plug-and-play harnesses in Japan where you plug the existing wire harness to this already-spliced wire kit, and the kit plugs into the ECU with no problem. What I'm saying is that you can't use the harness but you can just "T" all the wires.

So does anybody have the correct diagram then for a 98+ GS300???

Or if you have one installed, look at the ECU and post the wire colors that have been taped.

I used the diagram T 10a for Gs400 and also for Gs300 with Hot wire sensor type. Good luck you guys.

What do you mean by "hot wire"?

CSHFLW,
if you look at the Wire Manual again there you will find an ARISTO for 98-* and the Diagram is T10a. Plus this layout is the same layout from Swift-Racing's Air Intake and ECU. There are 2 differences, one the Swift Air Intake uses 2 Sensor while the AFC only uses 1. The other difference is that the AFC uses the Throttle position while the Swift Intake does not. So after investigating the differences between the 2 diagrams I think the T10a is what we want to use. I have a dyno appointment Sept. 19. I'll let you know if that's the correct diagram to use and how much hp/tq I gain. I only gained 11 rwhp from the Swift Intake and ECU.

10A is listed for a 98-* SUPRA.

CSHFLW,
Yes you are correct but so is the ARISTO. Please look at page 7 of the Wire Manual towards the top. Here is a link:

So I should follow the 10a Diagram exactly for my 2000 GS300? Anything else needed?
