I think what you mean is that it never gets into closed loop. But, it does go into closed loop with a 160 t-stat, but not when it should, and the result is a poor running engine thanks to a very confused ECM.

However, when you install an ECM chip, you MUST follow the directions that come with it. The chip alters the ECM, and it's parameters. Therefore, if you were to install a t-stat other than what the chip calls for, you then would be confusing the ECM.

Take care,
