Idle Setup (Cable Driven Throttle Body) No aftermarket throttle body should be expected to work out of the box. Also, if you have a large cam and/or more displacement changes may be required of the stock throttle body. All GM vehicles with cable driven throttle bodies (not fly by wire) use what is called an IAC motor. This motor controls
Curious about how our send in mail order tuning program works? Check out our infographic below! The process is simple and straightforward. Mail in your ECM/TCM, we’ll program it and ship it back. No relearns needed!
It is common for folks to make the mistake of crossing oxygen sensors when reinstalling during a build. We notice this a lot while reviewing datalogs our customers send in from remote tuning – in the datalog it becomes obvious to us that the oxygen sensors are not plugged in correctly. If we note this in your file, please use
Check out our handy chart below for identifying GM MAP Sensors (listed here), along with linear/offset data. If you need assistance deciding on which one to use, shoot us an email at sales@pcmofnc.com! Click on the chart to enlarge.
For common remote tuning questions, click HERE. Otherwise, check out our video and graphic below on setting up and obtaining a datalog during our remote tuning process. Datalogs must be 15-20 minutes long, and encompass all states (cold start up, part throttle, WOT if safe). Note: We do not accept wideband feedback through external ports/PIDS (i.e. 5v AC). You must
How does remote (email) tuning work? We offer remote tuning with HP Tuners. All files/datalogs are submitted via email, and uploaded/recorded by the end user. This is basically mail order tuning except you have the ability to send us datalogs so that we can fine tune your set up. This is an excellent route for someone who wants to take

Displacement on Demand/Active Fuel Management (DOD/AFM) and Variable Valve Timing (VVT) DOD (also referred to as AFM) and VVT became options starting with Gen 4 LS motors (5.3L, 6.0L, and 6.2L). DOD/AFM disables four cylinders (1,4,6 and 7) at cruise. VVT is Variable Valve Timing. Some motors had both, some had one or the other, and some had none. This
Piston to Valve Clearance Calculator Click HERE – and then download “Piston to Valve Clearance Calculator.xls” Whenever installing a new camshaft, a set of heads, or a fresh build entirely, it is critical to check piston to valve clearance. At top dead center, at the end of the exhaust stroke and beginning of the intake stroke, the exhaust valve
Idle Setup (93 & Older) No aftermarket throttle body should be expected to work out of the box. Also, if you have a large cam and/or more displacement you should pay close attention. All GM vehicles in our focus use what is called a IAC motor. This motor controls a air bypass in the throttle body which basically controls your
