What should the idle speed be on a Corvette Z06?
What should the idle speed be on a Corvette Z06?
For example, on the ’08 Corvette Z06 with an E38 ECU, this table offers minimum airflow control for each gear as well as Park and Neutral and for engine speeds from 250 RPM through 8,000 RPM. Most E38 and E67 calibration files are similar this way. Since we’re tuning for idle only, don’t worry about anything above 1,200 RPM for now.
How to idle a LS7 corvette Cam properly?
LS7 Corvette CAM CONTINUE TO PAGE 2 STEP 1. If you have the air/fuel ratio set properly and your engine can idle somewhat decently, even if it’s by holding the throttle pedal down off closed-throttle to keep the engine from stalling, you can begin by setting a ball-park ignition advance value.
What should idle speed be for LS big cam?
The stock tables in the OE calibration are mapped for a cam that will produce lots of vacuum at idle speeds of 550-700 RPM. Lots of intake manifold vacuum at idle allows for a greater degree of control over torque output as there’s a lot you can do to control the pressure each cylinder produces during the power stroke.
What’s the best idle speed for a small engine?
If the cam is between 224-236 degrees duration (again, on the intake side) try a target of 900 RPM and for cams bigger than those listed above, set your target engine idle speed to 975 RPM. These will be a good, easy starting point depending on your engine setup.

How many horsepower does a Corvette LS1 have?
The LS1 also changed the firing order to 1-8-7-2-6-5-4-3 which is aligned with more modern V8’s. When the LS1 was introduced in the C5 Corvette, it was rated at 345 hp (257 kW) at 5,600 rpm and 350 lb-ft (475 Nm) at 4,400 rpm.
