Tried reloading ms3pu firmware and fresh main controller ini. All I’ve gotten so far for afr readings on tunerstudio gauges is a 25.5 afr right after powering down the Spartan. while the gauge wired into the analog outputs reads 14.2 for 5 seconds them 17.4 for 5 seconds then flutters around 22.3 till I power it down. Again only on the external gauge hooked to the Spartan 3 analog 0-5v output
