Learn how to confidently tune GM Gen 3 LS ECMs and transmissions using HP Tuners, from fueling, airflow, spark, and idle to diagnostics and 4L60E/4L80E tuning. Understand what to change, why you're changing it, and how to build a complete tune from start to finish.
These courses will solve all of your tuning problems:
Master GM Gen 4 LS ECM and TCM tuning with in-depth training on MAF, VVE, fueling, spark, idle, torque management, diagnostics, and transmission calibration. Learn a proven tuning process that gives you the confidence to handle everything from stock vehicles to modified combinations.
Learn the advanced strategies behind GM Gen 5 LT tuning, including airflow, fueling, torque modeling, Driver Demand, spark, VVT, SOI, diagnostics, and transmission tuning. Understand how the Gen 5 ECM actually works so you can properly calibrate modified vehicles instead of simply copying someone else's tune.
Get complete access to Gen 3, Gen 4, and Gen 5 ECM & TCM training in one comprehensive HP Tuners program. Build the knowledge and confidence to tune a wide range of GM LS and LT vehicles from basic bolt-ons to advanced combinations.
By the End of Your Training, You'll Know How To:
Build a tune from a stock file instead of copying someone else's calibration
Know where to start when tuning an unfamiliar vehicle
Tune stock, bolt-on, cammed and boosted GM combinations
Correct MAF, VVE and VE fueling using actual datalogs
Understand MAF vs. Speed Density and when to use each
Dial in idle and drivability on big cam and forced induction vehicles
Properly characterize injectors and fuel systems
Tune spark, knock control and Power Enrichment without simply guessing at timing
Understand real vs. false knock and how to determine what the engine is actually telling you
Understand and correct torque management instead of blindly disabling it
Tune 4L60E/4L80E, 6L80E and newer transmissions
Understand shift scheduling, converter behavior and transmission torque management
Diagnose problems that aren't actually tuning problems
Look at a datalog and know what's wrong, what needs to change and what to do next
Struggling With Any of This?
“I have HP Tuners, but I don't know where to start.”
You'll learn a start-to-finish process you can follow instead of randomly jumping between tables.
“I can make changes, but I don't know if I'm making the RIGHT changes.”
You'll learn how to use scanner data to determine what the vehicle actually needs before changing the calibration.
“I don't really understand what the datalog is telling me.”
That's one of the biggest focuses of the training. You'll learn what to log, how to organize the Scanner, how to interpret the data, and how that information translates into changes in the Editor.
“My cammed vehicle won't idle or drive right.”
You'll learn how airflow, fueling, spark and other strategies work together so you can address the cause instead of constantly chasing the symptom.
“How much timing should I run?”
Instead of giving you a magic timing number, you'll learn how spark advance, knock control, fuel quality, airflow, load and the vehicle's combination affect what the engine actually wants.
“Should I tune the MAF or go Speed Density?”
You'll learn how both strategies work, how to properly tune them, and how to decide which approach makes sense for the combination you're working with.
“Is this a tuning problem or is something actually wrong with the vehicle?”
You'll learn diagnostic strategies for failing fuel pumps, incorrect MAF sensors, real vs. false knock, airflow correlation problems, mechanical issues, supercharger belt slip and more.
