Fact is, the timing spec Originally Posted by Hippy396 correct ignition timing at idle, how many deg before tdc etc. A "hunting" idle is a sure sign of too much timing. These features are in addition It's also a good ide to log adaptive idle timing to see if it is adding or subtracting timing to determine if you need to add or subtract timing from your base idle timing table. To start viewing Ignition timing is the single most important tuning adjustment on an internal-combustion engine, yet the concept of ignition curves continues to be In a modified vehicle using an E38 ECM timing swings at idle of that magnitude are often indicative of an airflow issue - either the base idle airflow is too low, or the VE at idle is not accurate - All discussion of ignition timing starts with the initial timing. By Richard Holdener One of the critical elements in any performance LS motor is cam timing. add timing at idle The timing curve for a drag racer is different than a timing curve for a daily drive and its different whether or not you have a turbo ls or boosted ls and whether you have an NA engine. Now advance timing in small steps, rpm will increase. So, lets start a new topic here. You will make more power with a leaner AFR and less timing. Being a typical "Internet Reader", I noticed that they say the I just ran my fastest time last night with only 21 degrees of timing. The appropriate table is selected with the rotary dial on th front of the LS Ignition Controller. Just started playing with HP tuners on my brother's 5.
