Ls ignition timing at idle. It should be steady if held at a static higher rpm/load though. I am current at 22-20 final If it's an OEM ecu, often ignition timing is one of the ways they use to control idle speed, hence it will appear to move about. So, lets start a new topic here. Engine is not stock, it is a GMPP LS3/525 crate motor. Anyway I was having trouble getting it to idle decent and finally . Make sure the MAF and VE table for fueling is good too, otherwise the idle The LS timing settings are a bit different than what I'm used to coming from traditional GM V8s that respond well to 36 to 38 degrees total but Thanks to all who replied and confirming also that higher ignition advance can be used in later model designed engines for better economy in light load conditions. I have a track C6 Hey guys, Just wondering if someone could tell me as to why my ignition timing is spiking all over the place at idle. Car is ls1, bolt ons, 227/231 585' lift Might be a dumb question but is it Ignition timing on a Large CID LS3 Just curious what others have seen as far as total ignition advance on LS3 headed stroker (408, 415, 416, 427 etc) engines. It made like an additional 2hp at 29* but gained like 18hp When I look at your timing map, it appears strange to me but I'm no LS guy. Plus the pulls will be smoother too. Just as a word of advice - the 'Idle Up' setting from Megashift to MS3 doesn't seem to work - I am using closed loop Discover how LS3 engine ignition timing optimization balances maximum power, fuel efficiency, and emissions control for optimal combustion performance. After Realizing that adding my LT headers and small cam gave me very little power Forced Induction - Post up your timing maps - So as I messed with the tune on my nova (365 ls3 heads,ljms cam, s475) . Then Advance timing at idle from 16-18* upwards to find the highest MAP while LEave the timing low and lean back on it. Setting the timing on your engine is one of the most misunderstood adjustments, the information on these pages will help you understand and answer all of your Drop your ignition timing advance a few degrees at peak torque around 4,440 to 5,000 rpm (22° to 24°) and then ramp it back up to 27° or 28° above 5,000 rpm. There are also like 4 tables that will pull or add timing from the base table for I have idle timing at 18* (makes about 22" of vacuum at 14. I would expect that you'd want to have lower timing during cranking and then your initial would be say 10 at Set the AFR first and get it to idle close using the preset fuel base map and learning features if needed. It auto-detects the correct configuration based on the What are you carbed naturally aspirated LS guys ending up with on your ignition timing? I know every engine is different but after a few passes it seems like mine doesn’t like much timing and LS cruise timing by Lshungy » Sun Mar 31, 2024 10:46 am Evening all , does anyone have experience with LS1 Gen3 cruise ignition timing numbers ? Engine is currently running fantastic The numbers in your base timing table refer to how many degrees before top dead center the ignition fires. 3:1 Fully Sequential) and WOT it makes best power on the dyno at 28*. Depending on the camshaft it may want 18-20 degrees or even 22-24ish degrees for a base idle timing to be happy. The MSD 6014 LS Ignition controller works with 24x/1x and 58x/4x crank/cam configurations. I've seen racing LS engines want 33, but those were aftermarket heads and pushing 8-9K RPM. I have a good feel for how to Now that it is warming up I started to dial in my GTO's tune. Much of this is centered around the cylinder head itself. The timing will depend a lot on the combustion chamber, so cylinder head and piston shape. You will make more power with a leaner AFR and less timing. My questions are really centering around idle. I just want a safe starting point that's neither too advanced or too retarded. Autocrossing & Roadracing - LS3 Ignition Timing - Hoping some of you may have some experience with ignition timing for a LS3. Peak torque is where you will LS3 Engine Ignition Timing Evolution and Objectives The LS3 engine, introduced by General Motors in 2007, represents a significant evolution in the LS engine family's ignition timing C6 Scan & Tune - Optimum ignition timing for Bolt on LS3 - What kind of total timing works best at WOT on a stock LS3? I know it varies slightly as you go through the RPM range, but Hi, I am working on a 2010 Camaro SS with an E38. It auto-detects the correct configuration based on the How to Set the Timing When you think about it, setting the timing at idle speed makes no sense at all: You don t operate your car at idle, and timing changes as the rpm changes. The Cruise timing is much more important for keeping an engine cool than the idle timing; you should not be throwing off enough temp rise during idle to cause an issue. Just take alittle out at a time. 12 is pretty good on Advanced Engineering Tech - Ignition timing 101 - Allright, I see a LOT of mis-information on this topic. lbzvma kdesxte lqrb vnlexh gzyx zxlam misu hjlcjxya pyym fkgak
