AEM EMS Connects but all values go everywhere

[j87w]

Ive got the AEM EMS to connect using a IOGear USB to Serial adapter. The TPS Voltage stays at 2.4-2.5volts with just the ignition on (even at closed throttle and WOT, and with the TPS plug disconnected). It shows 2.2 volts even though I checked the incoming power and its 12.2 volts (I even put a battery charger on to make sure the battery had plenty of juice). It shows the A/F is 4.5:1 with the WB02 unplugged (external AEM WB02 Gauge). It says there is engine load, map pressure, ect (with the engine just in the on position). I have reinstalled the software, reinstalled the USB to Serial adapter software, Checked to make sure the ECU plug was plugged into the EMS all the way, ect. I know this harness used to run a stock ECU just fine. Any ideas? This is on a SR20DET by the way but it almost seems like a software issue or something.Thanks guys

You have to go into the settings, it's set up to show you afr as based on methanol out of the box. Once you get that sorted you'll be showing in the 11-12 range that it actually is.

What do you think about the TPS voltage. I started the car and it idles half a** and seems to run ok. I checked it with a meter and it shows .45V Closed throttle and 4V at WOT. The aem display still shows 2.4-2.7V no matter what throttle.

I checked fuel type and it is set on gasoline.

I got another serial to usb adapter and tried it. Now the TPS voltage reads 4.3-4.6V regardless of throttle position. Coolant temp with the car off reads 45F and IAT reads 55F (which sounds about right, the car hasent been started). Vehicle speed shows 0MPH which is right. Ignition timing is 10 degrees with the key in the on position. Fuel Injector #1 pulse with the ignition in the on position is 9475-9495(moves back and forth rapidly). 02 #1 AFR is 4.45:1 (set on gasoline). Engine load is 93.24 KPA regardless of if the car is on or off. I even tried to reload a new map with the new USB cable.

Finally after going through manuals and doing some thinking I figured it out. Pin 19 Output from UEGO WB02 (stock NB02 input) and Pin 20 (TPS) are right next to each other. They use the same color of wire. Somehow I mixed up the wires. I cut the TPS wire so it was no longer connected and soldered the Output from the UEGO WB02 into pin 20. Thats why the TPS was reading the weird voltages. I no longer had an 02 sensor so pin 19 would just read 0 volts (10.00 A/F Ratio). I swapped thie wires and it works fine. Now I just got to find out why it idles at 10.5:1.

Have you set your throttle range and base ign timing yet?

[j87w]

Yeah, I have set them both. I have my injector size set about 780cc (Tomei 740cc Injectors) and Im still about 10.8-11.2 at idle.
