TPS setting?

TJR · 01-24-2002, 10:57 PM

What's the best TPS setting? Everything I've ever read has said to put it at .98v. Also, what would happen if it was set too high (ex: 1.01v)?

.98 is good. 1.01 is part throtal

The safest setting is .95vdc. For MAF 5.0 Mustangs, at 1vdc, the ECM thinks you're driving, rather than idling, and the end result will be a "hunting" idle. This happens at 1.1vdc with Speed Density 5.0 Mustang engines. SD engines have a slightly wider range, and are safe to adjust right up to 1vdc, but it's still a good idea not to go past .95vdc. Make sure the engine is warmed up before you test it because the readings are often different cold than they are hot.

Take care,
-Chris
