Thread: Remote Tuning

    I've searched & searched online, but can't find a factory LS3 timing graph (vs load & RPM). The engine is basically a factory LS3 with a cam, sold as a crate motor. Literally thousands of these motors out there, but I can't find the timing info that I need anywhere. If I could find the info I could just enter in the Holley EFI software and be close at least.

    Well you connect to a remote tuner from any place that has a WiFi connection, even the dyno cell. I've been on a few remote tunes where we helped an engine builder with an engine on the dyno. You just need a WiFi connection and the ability to see the laptop and to communicate. A headset for the phone helps a lot if you're going to be talking and twisting wrenches at the same time.

    If you just want help with startup and idle, then connect for a remote tune from your garage. A lot of issues can be resolved by having an expert look over the tune before firing the car. Then you fire the car and start to go through the checklist to see if it starts, idles by itself, correct idle speed, IAC acting correct, AFR correct, idle quality, etc. There are a lot things a remote tuner can look at and help with before the car even leaves the driveway.
