True and false. True that the 160 thermostat will not keep the computer from entering closed loop. False that closed loop is only time based. It *does* depend on ECT, but it's very low -- about 135 if I remember correctly. And of course it also depends on load, the computer will not enter closed loop in a high load situation. And also, a H/C/I 5.0 will miscalculate load, causing open loop to occur much more often. This can be fixed with a good chip or EEC tuning device.Grn92LX said:Wrong. The 160* stat will NOT effect going into closed loop. Open loop to closed loop is TIME based.
For the guy who suggested measuring with the highway markers -- bad idea, they are very inaccurate in most cases. I've checked using my GPS and found that the markers vary by plus or minus 20%. Use a GPS if you want to verify your speedo reading.
