AF in display not reading wideband correctly

[365motorsports]

what would cause the wide reading in display not to read correctly? its only showing 1 to 2 afr. wideband gauge reads fine. digital wideband input reads what the wideband is displaying. AF under closed loop is not reading correctly in the display

You should try your ECU in a known working vehicle as it should read the MAP sensor without running with the ignition on. There may be a wiring issue in your vehicle.

There isn’t a wiring issue. I have 5v at the plug. With the koeo i can pull vacuum on the map sensor and the tracer moves. To -19 to 22” when cranking the tracer never moves. You have to hold foot on the throttle to get it to idle but it fouls the plugs out bc it’s not registering the map sensor volt. Didn’t have an issue with the other tuning setup in the car. So the wiring harness is good. Same harness different engine. I blew the other engine up

What does it do when you try the ECU in a known working vehicle?

Have you tried using the OEM MAP sensor?

[365motorsports]

I don’t have another car to test it in. Factory map sensor does the something. My other cars are flashpro. On a engine simulator everything test fine in the software. Bought and registered this s300 before xenocron shut down. Never installed it in my car until I started this thread. Not sure what else to do. I don’t tune obd1 cars anymore at the shop. All the rest are Kpro, flashpro, stand-alone ecus or other flash based tuning. All the manual tests show on the ecu with the software shows everything is good. Did you take a look at the datalog?

Try to find someone local to test in their vehicle as this will tell you immediately if it is your vehicle or the ECU.

I found an issue the exhaust cam gear slipped to -4 on the skunk 2 pro 1 exhaust cam. I fixed that yesterday. I tried to start it and now the s300v3 wont connect to smanager. Smanager isn’t recognizing the usb. I tried the other cable from my flashpro same thing. Tried reinstalling smanager. Still won’t connect. Only 2 leds are lit on the board. The red led flickers then goes out never comes back on.

Check grounds in the engine bay then reboot the laptop and try again.

[365motorsports]

Nothing wrong with the ground. Nothing changed with the one on the thermostat housing. Tried a different laptop same issue. My old tuning hardware connects to the old software. Ostrich with hulog.

[365motorsports]

All I did was moved the cam gears to the correct degree

[Spunkster]

That will not change how the s300 connects to the software.
