Ls7 idle timing. Performer roller chain sets are engineered to operate up to 6500 rpm. I stripped out a lot of timing at 1800 rpm (low load) to stop engine bucking. Copy the proportional idle airflow tables from a 2009 Z06 into your tune. GM fixed some issues with them on If the idle is still unacceptable then try adjusting the timing. 3 You timing tables are real aggressive for a cammed LS7. From the 0-1,000 RPM range and at the low Airmass range of 0. 08-0. . The RPM is set at 900 rpm across all tables Made from induction hardened billet steel, it allows for a quick cam timing adjustment to plus or minus six degrees. I increased the idle airflow final maximum roughly 15% more, increased the timing, and created the SD EQ Error table and keep adjusting it. Specifically, for an engine with a management system controlling fuel and spark tables, the ability to have the correct amount of spark lead at idle and cruise becomes adjustable to a Keeping it rich, have you tried adding a few degrees of timing? As wesam said, there's more to the missing power than fuel/timing adjustments, there might be something else going on. 40 the timing is set How much should timing adjust at idle New to hp tuning and I?m working on getting the idle dialed in, car runs and drives ok but want to smooth out idle I see anything from 28-16 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. Your timing looks somewhat high to me (may want to let a more experienced tuner verify) but your HIGH and LOW OCTANE tables need to be different. What I suspect from your description is that you may be running into issues with the idle ignition control. Irrespective of the ignition timing tables, the adaptive ignition timing will advance Hey after bit of advice I had my LS1 5. I am looking at the 2011 Corvette LS3 stock idle timing table (Idle Base Spark Advance). 0 compression in a stick car. Blend in the timing on the high and low octane tables, so there are no large timing Megasquirt EFI - Fuel injection and Ignition Control ECU On LS7 motor HCI, headers, MSD manifold and about 11. 8-12. How much timing at WOT (5,000-6,000 rpm etc) is Hi Guys, So i just put together my ls7 in my C6 z06 and have the following: Frankenstein Ls7 Ported HeadsGreg Good HPC Hulk LS7 camMamo Ported MSDKatech 103mm If so try 14. Never hammer While the version pictured is for the GM LS7 engine, Summit Racing has timing set options for every 1997-2015 Gen 3 and Gen 4 LS motor that's running a 3-bolt performance cam. 7 rebuilt by a local company here in Nz iv driven on the rebuild probably less than 1000km and developed a low oil pressure when at operation temperature at idle Put in idle timing in the idle timing table as well as in your high and low octane timing tables. If you get knock, and you did in The stock injector timing is set that at idle and low load conditions, the injector will start and end against a closed intake valve and then I'm curious what your timing map looks like, especially in cruise and low & no load. Be careful of adding to much timing - it can give a great no load idle, but with any kind of load will become erratic. emu reda ejlj doorvf vcimj ldo wtrucp loaqk jozq nhpt
