This engine uses a cable-driven throttle body with a 24x crank trigger and a 1x cam sensor at the back of the block. Some VE calculations use the air temp to modify the pulse width as a “background” calculation whereas the user can do this via the air temperature enrichment table. This gives a 6-string guitar I prefer to define single dimensioned tables in a single-column, multi-row (though some people prefer single-row, multi-column). Latest Fairmont Microsquirt 2 V3 tune running fuel and spark reading off the stock crank trigger. The genesis for MAFless tuning of the LS1 in Australia was the HSV GTS version of the Holden Commodore , which was factory fitted with a Callaway-developed C4B version of that engine running in MAFless mode. 9. Well, the thing is I used the VE table from my old tune (346 CID) as a base for my new tune. Generally speaking, the VE changes resulting from a change in cam have a greater dependency upon RPM than MAP. 2003 block, 08 pistons and rods, 243/799 heads, ls1 intake, 80lb siemens deka injectors, 80mm turbo. Under Power Enrichment, click EQ Ratio vs. Then the VE table is tuned to achieve that AFR. I have an L77, you an LS1, so on the face of it we both have Holden V8s but criteria to inform the best tuning approach is completely different between GenIII LS1 and the latest GenIV L77 engines, specifically due to revisions in ECU speed/capability, MAF resolution, and VE as a result of different ci, heads, cam, intake and exhaust. . . 624 lift, 231/239 duration, and 113 LSA.

Save the PID file as SD tuning. The values in this table are Equivalence Ratio's (Fuel/Air multipliers or AFR divisors) ie. Common Tables/Parameters Table Comment Fuel Volumetric Efficiency (VE) Used in fuel calculations to determine how efficient the engine is (and hence how much fuel is required). For the most part, this will work for just about every LS based engine vehicle. Gear. Volumetric efficiency (VE) is the term used to describe the amount of air an engine is ingesting vs. . Rather than calculating the air flow from the VE table and manifold pressure (MAP), you can use a mass air flow (MAF) sensor measure the amount of air directly. Shady business needs to be called out in it. A couple of heat cycles on the springs is all you will need. 0L aluminum-block V8 car engine that first appeared in the 2006 Holden SS Thunder Ute, Statesman/Caprice and VE Commodore. Ideally this setting should be turned on before any tuning and the AFR table set to your target AFRs. . There will be some differences. Spark tuning is also fairly easy for anyone to pick up. MAF (g/s) vs ECT at Idle. So the two aspects are independent of each other, no extra full throttle power can be given with a fuel economy tune and little if any extra fuel economy can be given above the I have an 04 Silverado PCM and Ive swapped LS3 heads, intake, and injectors on my 6. It contain modifications to the VE Table, MAF Calibration Table, Spark, and include all the Idle Parameters changes described in Idle Tips & Tricks and the Idle Tutorial. It is designed to work in Internet Explorer 6. 0, though it may work with other browsers. For the article, we are using a MS2 ECU… Injectors. However, the lower 4 strings are tuned an octave up from the standard. The closed loop settings are best used to compensate for load changes, such as turning the A/C on. The VE table corrections can be derived by the following formula: (+-LTFT%) + (+-STFT%) = Final % Learned If your LTFT histogram value @1600 RPM, 30 Kpa Map is +7 and the associated STFT value is -2 your total % fuel correction is +5. Trying to auto-tune using a wide-band that isn’t calibrated This calculated VE table will need to be tuned carefully to avoid damage to your engine, however. The following table is the Target AFR table, and you can see how the left hand column (Primary Load) is set to go from 20 to 205 - obviously intended for a manifold pressure (Speed Density) based primary load, running up Open TunerStudio and navigate to 'Basic tables→Spark Advance Table' then click on the down-pointing greed arrow icon, and browse to select YourFile.

Reduced the fuel input in the starting tables Changed the MAF tables I have cleaned, checked, and swapped: MAF, throttle body, and air idle control. Airflow model-based (VE) tuning eliminates lookup of many correction tables needed in previous generation ECUs. . There are two tables that control commanded AFR at WOT. First, some background information on how the Subaru ECU controls Air-to-Fuel Ratio at low load (idle, low throttle, cruising) where AFR is kept at ~14. 0L LQ4 engine can be seen below. 7 is too lean, but if the commanded PE is say 12. 0 stroke), HPT automatically reduced the VE table the same percentage amount I increased the volume. . When tuning for larger injectors, don’t go messing with the Mass Air Flow (MAF) table, or this could happen. During unsteady state, the PCM uses the VE table to calculate airmass and it is offset (multiplied) by the last calculated VE Correction factor. Its idling at around 950 even though the tune is calling for 850. With a narrow band oxygen sensor, tuning the fuel mixture involves setting up a VE table(s) which is rich (by increasing the entry in the VE table(s)) at high loads and rpms, or lean (by decreasing VE entry) at low loads and rpms. com Hot- this table should be set the same as the normal table, unless you wish to change the settings slighty for a limp mode when your transmission runs in “hot mode” Full throttle shift speed Normal- this is the maximum speed you will be doing for your 1-2, 2-3, 3-4 upshifts, and the maximum speed you will be doing for your 2-1, 3-2, 4-3 GM’s E38 and E67 controllers are the most flexible for tuning of those matched with factory LS powertrain systems, with the E67 being the best for forced induction. May God's grace bless you in the Lord Jesus Christ. Gradually increase the cruising speed up to the max speed you’d cruise at tuning it in as you go one cell at a time.

Write Vin/Tunerlock/Vats - Change VIN - Relink VATS - Tune a few more engines with big injectors and you'll find out why you may have to re-scale the VE tables. ) I uploaded the "MAF enabled" tune, exact same VE table, drove around ANOTHER hour or so, and the LTFTs are 0 to +13. It is essential that the user reads all of the Omex manuals before attempting to install the system and before attempting to start the engine. The most important thing with VE tuning is to drive around as long as possible and try to hit every cell in the histogram that you would normally see under part throttle daily driving. How do I make sure my IFR tables are correct? Ive found stock tunes for LS3 and LS7 Vettes on holdencrazy but dont have the knowledge to swap/convert everything. I have checked fuel pressure (40 psi). Unfortunately, it'll be difficult to tell without a load dyno whether or not that's MBT for your configuration. Round up to the nearest tenth to make the mixture leaner; round down to make it richer. Changing the values in the Target Air/Fuel Ratio Table is easy; click and drag all of the cells with the same value, type in the value you desire, and press Enter. The LS1 is a high performance engine and there are two main reasons why they can be made to perform so much better: 1. Turning the setting on/off will require a complete re-tune. The goal is to have your MAF, VE, and Desired Airflow all utilizing identical Airflow Values. After tuning the Base VE table in closed loop with minimal correction, the progressive nitrous feature in the XFI was used to turn on the nitrous at 3,500 rpm and over 85 percent throttle and ramp AFR control provided very good numerical control over the tune-up. If the engine is ingesting the maximum amount of air it can hold, then that engine is considered to be operating at 100% VE. Sept 21-23: Mastering Server Tuning – iCal – prerequisites Each class has hands-on labs for you to follow along. This step occurs after ensuring that your base ignition settings are correct and the car starts, but before actually taking the car for a drive or presenting load to the motor. . Spark advance seems to be pretty conservative though, the low octane main spark advance table had a whole -1 degree advance timing from 4400 to 6k RPMs; the high octane was set for 10. 03 bore, 4. 117 6. Cheap, Effective, and manufactured in extreme bulk, 99-13ish (since 14 is now the direct injected LT series engine pouring in. Whether you are tuning an engine on an engine dyno or a chassis dyno, you should always make sure that it gets tuned to the proper amount of ignition timing. The cylinders can be bored to the LS1/LS6’s 3. Again, the car would run fine without it, but could run even better with it. In LS swaps or street/strip/race cars a carbureted LS is simple, cheaper, and often can make more top-end power than EFI. Basic functions such as fuel, ignition and idle programming are covered as well as more advanced features such as anti-lag, rev limiters, traction control, closed loop PID control, boost control, and much more. All we needed was a representative motor. Read each course’s prerequisites at least a few days before class because setting up your VM will take quite a bit of time the first time you attend a Mastering class. . It uses three types of files to operate, xdf (definition files) bin (binary data files) and adx (data acquisition files). 80% in all cells in the VE Table, setup as actual VE values will get you in the ball park to get it started. Here is a video of the coil in action - with the LS1 on the test stand you can hear the sparking, not loud but certainly audible.

Mass Air Flow Tuning Mass Air Flow (MAF) tuning consists of adjusting the values of the lower VE and mass air flow tables. . Also, unless your compensation tables are set up perfectly, the AFR ratio can change as the temperature goes up or down. Traditionally the VE table is 3D and has two axes Engine Speed (RPM) and Manifold Pressure or % Load. Your LS & LT TUning Solution My name is Casey and I've been tuning professionally for the street and the track since 2007. When we tune a car the fuel table is made accurate and when a car is at low loads when driven gently it is in a different part of the map than when its at full throttle. E85 fuel, methanol injection. AFR should be somewhere between 13-15 at idle once at operating temperature (should be adjusted to around 13. The ECU is following this table and obviously an engine could not quickly change its fuel requirements so smoothness is the key. 0-liter LS engine, originally from a 2001 truck, and you’d like to drop this into a sweet little ’67 C-10 pickup. Lambda values are simply a different way to express the AFR and are computed from AFR values. You’re trying to hold the rpms and load in a given cell and dial it in to perfection, then tune the next cell. Before your data is useable, you need to specify whether your load is throttle or MAP based. 7CWBK-ND, $1. The Fuel VE table then becomes far closer to a true VE table.
