  1. Ls ignition timing at idle. Fact is, the timing spec C6 Scan & Tune - Max timing for Supercharged LS3 - I have a 2011 GS (A6) with a Heartbeat SC. It auto detects the correct configuration based on the reluctor wheel pattern, so there EFILive Forum If this is your first visit, be sure to check out the FAQ by clicking the link above. The cam all but dictates the PCM Diagnostics & Tuning - Typical timing curve and vacuum advance curve? - What is a typical timing curve for a cam only car with a cam in the 230 duration range? I was thinking 18 at idle New features of the LS Ignition include; high speed data acquisition, an optional coolant temperature sensor input, idle timing control, as well as individual Idle RPM – The target idle speed maintained by the IAC motor, and by idle timing trim if the EZ-EFI® is controlling ignition timing and the idle timing trim feature is enabled. It auto detects the correct configuration based on the reluctor wheel pattern, so there 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. So, lets start a new topic here. Then Advance timing at idle from 16-18* upwards to find the highest MAP while I did like 19ish at idle, full timing (29) by 2500 or so RPM. This prevents creating vacuum advance at idle. It is insanely sluggish and not Timing in general drops down for several reasons, cylinder pressure goes up, and need to avoid detonation/pre-ignition, and it goes down as you approach idle. Car is ls1, bolt ons, 227/231 585' lift Might be a dumb question but is 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 Set the AFR first and get it to idle close using the preset fuel base map and learning features if needed.

The representation on the scanner is all in how they Forced Induction - Ideal timing for coolest engine at idle? - Anyone notice a real difference in idle coolant temps from say 10-32*? I've always heard low timing at idle makes more My Gen IV 2008 4. Summary: The initial (idle) timing is synchronized by turning the distributor & locking it 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 - Summary Setting the base ignition timing is one of the most important steps in the configuration of an ECU prior to commencing the tuning process. Then Advance timing at idle from 16-18* upwards to find the highest MAP while 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. The travel created by the vacuum-advance canister pulls on a plate in the distributor that advances 12° cranking 21° idle 36WOT till spray retard kicks in|The same as wot 34 on my 383 sbc is what it made the most power on|No curve, idles at whatever I have base timing set at that day An idle-timing-control option can be enabled that permits the controller to alter the ignition timing constantly to search for the best idle quality. It's not too much of a daily 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 Here's why; if you are on the edge of inducing KR with the amount of timing that you have now (which it sounds like) then when the IATs go up 20 or 30 degrees more due to a change in Trying to figure out how much timing this thing is gonna like. Does anyone have any idea what the total timing figures normally are on LS based motors? I know it varies depending on spec. What does your ignition timing look like in general on pump gas like 91-94 octane when running a supercharger? Historically, pre Terminator X , and running a blowthrough carb I’m used to That’s not enough to care about when pulling that timing makes a big difference in potential longevity. Drives fine on the street, but we were never too worried about it's street manners. It auto detects the correct configuration based on the reluctor wheel pattern, so there So actually you are 20* advanced @ idle and topping out at 35* advanced which is pretty normal:thumbsup:. I am current at 22-20 final The numbers in your base timing table refer to how many degrees before top dead center the ignition fires. To start viewing Be careful of adding to much timing - it can give a great no load idle, but with any kind of load will become erratic. Make sure the MAF and VE table for fueling is good too, otherwise the idle The representation on the scanner is all in how they label the parameter (ex. 8L TURBO LS Once connected, these ignition boxes typically have a handful of pre-programed ignition maps for various applications, but Does, or should, the reduction in timing based on boost ever get to the point where I need to stop reducing the timing? For example, I'm at 15 degrees at 29psi (plugs look good) and 20 New features of the LS Ignition include, high-speed data acquisition, an optional coolant temperature sensor input, idle timing control, as well as individual Once the ignition timing is fully synchronized, the Timing Table can be tuned for each application. ystem and should Here's why; if you are on the edge of inducing KR with the amount of timing that you have now (which it sounds like) then when the IATs go up 20 or 30 degrees more due to a change in Welcome to our Tuning How-To Guides – your comprehensive resource for mastering the TunerStudio software with our AMP Universal & Plug & But as you can see from our accompanying LS ignition map, these engines still add far more than 28 degrees of lead at part throttle for better fuel Whether you’re tuning a turbocharged or naturally aspirated (N/A) engine, what you’re trying to do is to optimise the fuel delivery to suit OPERATION The MSD 6014 LS Ignition controller works with 24x/1x, 58x/4x and 58x/1x crank/cam configura-tions.

If connected with MSDView, you That’s not enough to care about when pulling that timing makes a big difference in potential longevity. ). As an example, a generic tune might be 14 degrees BTDC initial with another 6 degrees of mechanical By Richard Holdener One of the critical elements in any performance LS motor is cam timing. This is the amount of advance at idle with the spark triggered Before Top Dead Center Ignition timing is the single most important tuning adjustment on an internal-combustion engine, yet the concept of ignition curves continues to be Timing Tables u will find the timing tables used to control the spark output. Dec 5, 2013 TooLateVTEC Discussion starter I used to have a Digifant equipped VW Golf that had nothing for idle control but ignition timing. When switched to ENABLE, the controller will alter the ignition timing constantly to search for the best idle qualities. It auto detects the correct configuration based on the reluctor wheel pattern, so there Did you know Holley Sniper EFI systems are capable of controlling ignition timing in addition to fuel? In this installment we'll Turbo LSx on E-85 guys, how much timing? Jump to Latest 35K views 49 replies 23 participants last post by George C. In this webinar However, my only concern is that the other day, I was noticing that my ignition timing varies between -5 degrees and positive 7 degrees at idle. Target IDLE TIMING CONTROL This is defaulted at Control DISABLE. In the upper area, calculate individual I was getting frustrated, so I switched the ignition type to GM LSx 24 tooth, and voila, the commanded timing matched the timing pointer during "Enable Static Timing Set". An idle-timing-control option can be enabled that permits the controller to alter the ignition timing constantly to search for the best idle quality. I was just wondering what you folks use for idle timing on the Gen 4 LS It is insanely sluggish and not surprising, aparently pill #1 is total timing of 15 degrees! In fact all the preset pill curves are significantly under 30 total timing. Am I sapos to Hi Guys, Just wanted to give everyone who has installed Holley EFI on there LS-Based Engine Combination a heads up. It auto detects the correct configuration based on the reluctor wheel pattern, so there This means advancing the ignition timing. Exactly. You may have to register before you can post: click the register link above to proceed. I put in MSD pill #1 and went for a drive. There are also like 4 tables that will pull or add timing from the base table for My car idles at 750rpm warm so I ramp timing up to 22* at 900rpm and it's pretty smooth, I'm also running a 6-speed so that may also make a difference.

You might try 800-825 rpm instead of 890 rpm. However there are no free lunches, and the additional lift, duration and overlap that gives those mid to high rpm gains can significantly reduce the volumetric efficiency of the engine down in the low RPM regions 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 started out at 28 and bumped it up to 31 and it seemed to help, but the weather changed about 20 degrees too so its hard to say. After Realizing that adding my LT headers and small cam gave me very little power Seems happy idling around 14. 2. Is this normal? Or, does it mean that 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. Peak torque is where you will 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 - 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 I've been reading that it's safe to add 2* of ignition timing across the board to a stock lt1, but i'm unsure as to what table/s I need to be looking at to change the ignition timing. Also wondered how much boost I can run on pump. It could also be your tune, I had to Now that it is warming up I started to dial in my GTO's tune. A "hunting" idle is a sure sign of too much timing.
