Hi, I've been checking data on my new mt2500.
Closed Loop after less than 1 minute on cold start.
O2 volts switch back and forth quickly.
CTS reads 180* when IAT reads 120-130*
But LT fuel trim is at 89 and ST fuel trim never gets above 100
Are these values a concern?
The Renix Fuel Injection Manual says they should read around 128 optimal but atleast 115-120.
Any insight is appreciated.
