Base tune 99 T/A M6....swapping in an LS3 headed 6.0 with 232/236 .625 .625 112+4 cam, GMPP intake, 90mm Edelbrock TB, 42.5 Lucas injectors...
Any advice on a base tune? I have HP Tuners Pro, but not a ton of experience with it yet....
Thanks!

Here's some base start up info from the hp tuners forum . Take a look over there. You will find a lot of info on the hp forum. There's a lot to it to just get the engine started. http://www.hptuners.com/forum/showth...-%28w-pictures

Hello,
First, you will need to find the injector data for your injectors which will work with HP Tuners. Get the serial number off the injectors and find the data. Then be sure to input it under your Engine>Fuel tab. As for Cam settings, it will vary depending on what ECM you have i.e. E38, E40, etc. Generally speaking, larger cams like about 15 to 19 degrees of idle spark advance and 12 to 14 grams/sec of idle airflow. Also, you there are two general methods of dialing in the idle. You can use spark advance to add or subtract timing to get your idle to match what your commanding, or you can use or IAC function (not a true IAC Valve on ETC cars) PID controller. The spark advance method is preferred, since it's how its done from the factory. Plus, if its an E38, I've found the IAC PID controller method to not be as successful.
Thanks
