Exclamation S-AFC Wiring

Ok I'm almost done installing this damn thing. There is one problem....
the Air flow signal(B136 #5) I see where it starts but where does it go? I cannot find it once you pass all the clamps and plastic tapes! I opened the end up on the ecu and see that it ends up being taped up and then seems to connect to something else.
If anyone has info on this help is much appreciated.

your best bet is to take off that tape. it'll make things much easier for you.

Ok I got it working now. I initialized it and turned off the car and turned it back on and now the problem is that my throttle position sensor is reading at 5.115 at all positions. Whenever I press the gas pedal is remains constant.
Did I do something wrong?
Thanks

Double check your wire for the TPS, you might have tapped into something else.

Yeah it works now. I had it spliced into the right wire but I guess they were not making good contact so I changed the location and everything is good...no engine light either.

I borrowed a G-Tech from a friend so I'm gonna try to "tune" it that way. Any one have a better way instead of paying ~$200 on a dyno? I figured the G-Tech can do horsepower rating so I'll find a strip of road and keep testing on that same strip and pull the car the exact same way.

Does anyone know some descent number to put in for a MY99 2.5 RS with only a ScoobySport exhaust? I know every car is different but I just wanna know do you start to rich the car out starting at likr 4K RPM and higher till like 6K? I'm probably gonna need to get a A/F ratio gauge.

Anyways thanks for help!

you'll be better off with an A/F gauge. trying to tune with a G-tech is basically worthless. it won't tell you anything about how your engine is running, which is what you need.
