Kpro 4. MAP sensor not reading

[nomdatyper]

Having a serious problem with my k swap. So I've checked for continuity from the map sensor plug to the ecu plug for the signal wire, no short in the wire. Tested ground and 5v reference on the map sensor plug it's getting 5v. Tried to test the map sensor by sucking the inlet to cause a vacuum reads voltage change on the multimeter but k manager shows no change. Why is this even possible I've even tried another MAP sensor.

Have you tried this ECU on a known working vehicle?

Haven't tried another car yet. Just got the ECU and KPro pre installed from Tegiwa. I've been told I should keep the standard o2 sensor as upstream and the downstream use the AEM Wideband because it's just flooding it every time I crank it.
