These modules are the more desirable versions of the preceding P01 due to a processor upgrade performed by GM. modified It is not hard to exceed this limit when installing aftermarket injectors for larger horsepower applications and requires some unique tune changes in order to get them to work properly. The challenge every good tuner has - and one we constantly work to overcome when teaching our students how to tune, is the variety of changes that these ECMs have experienced over the years. The last hoorah for the GEN 3 computers is the E40 control module. The first in the line was the P01, which was used through about 2003, with the best models denoted as an 0411, usually pronounced, oh-four-eleven. The MAF defines how much airflow is drawn into the engine by measuring the electrical resistance needed to keep a wire a specific temperature inside the air intake; this is called MAF Hertz. Odds are you already knew this, but I’m betting you don’t know as much about the ECMs that powered these legendary engines; from the original LS1 powering the 1997 C5 Corvette to the modern day Z06, they’re all great engines, but nothing without a great ECM to control them. You must be logged in to access the wishlist feature. 2009 - NEWER 58X LSA 6.2L SUPERCHARGED ENGINES. Another example is the dreaded Injector Flow Rate Limit.

These harnesses include the Gen II LT1/LT4, Gen III (24x) LS1/LS6 and Vortec Truck Engines as well as Gen IV (58x) LS2, LS3, LS7, & Vortec and GEN V LT / ECOTEC3 Engines. In the P01 computers, the MAF table typically reads from 1,500 to 12,000 Hertz. 2029 Route 88Brick, NJ 08724ph. ©2020 The Tuning School, Inc. All Rights Reserved. 11-14-2012 #14.

These computers were not phased out until 2016. The E40, on the other hand, splits the table into two with the first table reading from 1,000 to 5,800 Hertz while the second table reads from 5,800 to 12,200 Hertz.

Again, before we dive too far into the applications of the GEN 5 computers, let's define how to identify the differences of a GEN 4 and GEN 5 computer. This makes it one of the easiest ECMs to learn. 2006 to 2007 brings us into the era GEN 4 ECMs, dominated by the E38.

Even with its limited applications, the E78 had significant implications for what was to come. One thing is certain though, our team here at The Tuning School will be here leading the charge in teaching you what you need to know to be a successful tuner with the latest and greatest in ECM logic and technologies. Rear Oxygen Sensor, and EGR/EVAP Functions so your vehicle will run as The Injector Flow Rate Tables of the previous ECMs (P01 and P59) have a flow rate limit of 254 pounds per hour. The changes made are using the HP Tuners Virtual Volumetric Efficiency Table Editor, which makes your job much easier by graphically displaying the table as you see it - instead of as coefficients, which are much harder to work with for the typical tuner. While the E38 has these tabs and settings, they are not used in its applications. The GM GEN 4 VE Table moved to Virtual (VVE) table instead, which uses a series of coefficients to predict VVE. October 26, 2020, Tech Tips - Logging Two MAP Sensors As the OE Manufacturers continue to push the envelope on engine performance and technology, the world of ECMs is going to keep evolving.

we start by ensuring your ECM has the correct operating system for your

PSI sells Standalone Wiring Harnesses for GM Gen II, III, IV, & V LS/LT based engines and transmissions. Because of their widespread use for so many years, odds are you will spend much of the time working with E38s. The GEN 3 ECMs controlled many GM LS Engines from 1997 until approximately 2006 (model depending). modified For this reason, GEN 5 control modules need specialized attention when it comes to tuning them, which we address in our GEN 5 courses. correct MAF, Tire

See the illustration below for an example of the supercharger controls in the E67.

https://www.psiconversion.com/products/pcm-programming/ls-vortec-pcm-programming/. If it is 2017 or newer, then it is an E92A. they are tuned specifically for your set up! When tuning the E38, we typically find the Virtual VE system we discussed earlier in this article as the scariest part to handle; but any of our GM courses can teach you how to handle it easily.

Virtual Torque is a system that calculates how much Torque the engine is making at a given operating condition. Because of this, we group these ECMs into three primary generations, the GEN III, IV and V. This article will focus on helping you understand the differences, strengths and weaknesses of these computers, so if you want to get better educated on these computers, read on! 732-276-8589 Mon-Fri: 8:00am to 6:00pm ET What sets the E78s apart from their GEN 4 counterparts is the Torque management controls.
The E67 computer was introduced In 2009 with supercharged 6.2 liter LSA in Cadillac CTS-Vs and LS9s powering the Corvette ZR1s. A PSI For example, if the Maximum Torque Limit 1st gear Table says that at 2,000 RPM the engine cannot exceed 243 foot-pounds of Torque, but the computer calculates that the engine is making more Torque than that, the computer will take measures to bring the Torque down to the 243 foot-pound limit. By looking at the Driver Demand Tables, the ECM can map the amount of Torque at a given RPM or Vehicle Speed. correct MAF, Tire If you are familiar with a typical GEN 4 computer and how its Torque management functions, you will quickly notice stark differences in the E78. The critical thing to note is that in the Torque management section, you cannot simply “max out” the settings, because this computer is Torque-based - like the GEN 5 computers of the next generation; which we will discuss more in the next section, covering the GEN 5 computers. The E67 has a slight edge on E38, thanks to its additional input/output lines, thus making it the choice for vehicles with variable valve timing. Upgrading fuel injectors to something with a higher flow rate is a must in most performance applications. Based on that number, the computer knows how long to open the fuel injectors to achieve the desired air/ fuel ratio. Brandan Gillogly writer Jun 4, 2013 GM's E67 engine control unit (ECU) is the brain behind the LS9 and LS3, as well as many garden-variety four-, six-, … APPLICATION: The applications for this computer are not widespread, with the primary application being the gas powered 2500 Silverados which utilize the E78 to control an LS2 based 6.0 liter. So where Virtual Torque represents how much Torque the computer thinks the engine is producing, the Driver Demand Tables represent how much Torque the computer, Tech Tips - Mechanical Issues Causing an Idle Problem.

A PSI ECM is a great addition to your PSI Harness as they are tuned specifically for your set up! Differences and Applications of GM ECMs (GEN III, IV, & V). Selected Size Sold Out! we start by ensuring your ECM has the correct operating system for your If the GEN 5 computer you are dealing with is older than 2017, then it is an E92. In another radical move, the T43 found a home ‘inside’ the transmission. should when you turn the key.

The true difference comes in with Driver Demand Tables. Starting in 2011, we begin to see a new module come onto the scene called an E78. So where Virtual Torque represents how much Torque the computer thinks the engine is producing, the Driver Demand Tables represent how much Torque the computer wants to achieve. October 20, 2020.

This 64-pound-an-hour limit hung around for quite a few years until being raised to 127 pounds per hour in roughly 2010. correct MAF, Tire Knowing when GM started using GEN 5 computers is simple - if it is a direct-injected V8 engine, then it uses a GEN 5 control module. With this module came a glimpse of the future and what was to come from GM as they headed towards GEN 4 computers. it We do not offer custom tuning for The calculation is heavily based on the amount of spark advance air in the cylinders, as well as camshaft position and more.

Anti-Theft System), Everything is taken one step further and based on what Torque Driver Demand wants; the computer will manipulate the throttle body angle, spark advance, and sometimes fuel delivery to get the engine Torque to meet its target. The E40s are essentially a hybrid, a testing ground for GM to start experimenting with features and controls that would eventually become the GEN 4 computer. The T43 is actually tucked in with the valve body, and has yet to receive a service part number from GM. This is the ECM of choice that GM used on all of their supercharged cars until switching to the GEN 5 ECMs with the LT4 in the 2017 model year.
