To tune an LS engine after a cam swap, begin by resetting the ECU to its factory settings. Next, double-check the timing chain and sprockets for proper alignment. Then, adjust the valve lash with a feeler gauge according to manufacturer specifications.
After that, re-torque all of the head bolts and check for any vacuum leaks using a smoke machine or soapy water solution. Finally, use an OBDII scanner to read and log data from various sensors on your vehicle such as mass airflow rate (MAF), oxygen sensor voltage (O2V), etc., and then fine-tune parameters like fuel pressure, injector duty cycle, idle speed control (ISC), etc., until desired performance is achieved.
- Step 1: Install the camshaft according to the manufacturer’s instructions
- Make sure that all components are properly torqued and fastened securely before proceeding
- Step 2: Replace any other components associated with the swap, such as pushrods, valve springs, rocker arms, etc
- Again make sure to torque them down properly
- Step 3: Start up your engine and allow it to idle for a few minutes in order to warm-up the oil and get everything circulating correctly throughout the engine block
- Step 4: Disconnect the negative battery cable from your vehicle’s battery in order to avoid any electrical issues while tuning later on
- Step 5: Connect an OBD2 scan tool or laptop computer running dyno software into your car’s data port (usually found underneath of dashboard)
- This will allow you to monitor real-time readings from various sensors within your engine so you can adjust accordingly during tuning process
- Step 6 : Adjust air/fuel mixture by manipulating fuel injectors or carburetor jets if applicable on LS motor being tuned; this should be done in small increments until desired results are achieved
- Step 7 : Adjust ignition timing using a spark advance meter or timing light connected directly onto distributor cap; again make adjustments slowly until desired results have been met
- Step 8 : Reinstall negative battery cable back onto battery once all adjustments have been completed; start up car one more time and let idle for several minutes before shutting off completely
- Step 9 : Take vehicle out for test drive around town while monitoring gauges on dash board ; if everything checks out OK then no further adjustments need made otherwise repeat steps 5 through 8 as necessary until desired results are achieved
Ls Cam Idle Tuning
LS cam idle tuning is the process of adjusting a vehicle’s engine to optimize fuel economy and performance. This involves fine-tuning the air/fuel ratio, timing, valve lift and duration, and other variables within an LS motor to achieve optimal operating conditions for improved efficiency. With well tuned idle parameters, an LS engine can provide greater power output with less fuel consumption as well as smoother start-ups and better overall drivability.

How Much Hp Does a Cammed 5.3 Make?
The 5.3L Cammed engine is a popular choice for hot-rodders and car enthusiasts who are looking to boost their horsepower. With the right parts and modifications, it can make up to 500HP or more! To get that kind of power out of your 5.3L Cammed engine, you will need some performance upgrades such as a camshaft upgrade, larger valves, cylinder heads with high-flow ports, long tube headers and an aftermarket exhaust system.
Additionally, you may want to consider upgrading your intake manifold and throttle body in order to maximize airflow into the engine. Finally, if you’re really looking for maximum power gains from your 5.3L Cammed engine then adding forced induction (turbocharger or supercharger) can easily bump up the hp numbers even further!
What Should Idle Timing Be for Big Cam?
The idle timing for a big cam should generally be set to 10-14 degrees before TDC (top dead centre). This is because higher RPMs result in more heat and therefore, the engine needs its initial spark sooner. Setting the timing too low will cause slow or sluggish acceleration and poor fuel economy, while setting it too high can cause pinging/knocking in some engines.
It is important to keep in mind that the bigger the camshaft size, the more advanced you need to set your idle timing. If you are using an adjustable cam sprocket, then it may be necessary to adjust your timing after running a few dyno pulls if you feel like there’s room for improvement. Furthermore, when tuning with an adjustable ignition box such as MSD’s Digital 6AL series boxes or similar products from other manufacturers – it is important to pay attention not only to idle speed but also spark advance at idle; both of which can have a significant effect on how your engine runs overall.
How Do I Access Hp Tuners Tune Repository?
Accessing the HP Tuners tune repository is easy and straightforward. To begin, you need to be a registered user of the HP Tuners website. Once logged in, you will see a section called “Tune Library” at the top of your screen.
Click on this link to open up the library page which contains all available tunes for your particular vehicle type. You can then choose from either free or paid tuning options depending on what kind of modifications you are looking to make to your vehicle’s performance. Once you have selected a tune, it will automatically download onto your computer and can be accessed through HP Tuners software program or imported into another tuning software platform if desired.
The repository also includes helpful instructional videos that provide guidance throughout each step of the process so that even novice tuners can take advantage of this great resource!
How Long Does It Take to Install a Cam?
The installation of a cam, or camera, can vary in time depending on the type of camera you are installing and where it is being placed. Generally speaking, it takes about two to three hours for an experienced technician to install a basic security camera system that includes cameras and mounting hardware. Installation times may be longer if additional components such as control panels and wiring must be installed as well.
To ensure a successful installation experience, it is important to research what options are available when selecting a camera before purchasing one so that all necessary tools and materials can be gathered before starting the process. Additionally, reviewing any instructions included with the device prior to beginning the project will help save time during the installation process.
How to get your cam swapped LS to start and idle in HP Tuners
Conclusion
This blog post has provided a helpful overview of how to properly tune an LS engine after a cam swap. It is important to note that the tuning process should not be rushed, and all steps should be done in order for best results. Additionally, it is important to make sure that the correct components are used when performing the tuning process.
Finally, double-checking everything before hitting the road will help ensure successful and safe operation of your vehicle with its new cam setup.
