2). HIGHLIGHTED LIKE THIS, ARE WIRES THAT ARE NEEDED, AND GO TO EXTERNAL CONNECTION The computer can then seamlessly change the fuel output and spark advance on the fly to instantly compensate for a change in Ethanol content. I have been looking for adaptive idle but can seem to find or know if this will actually will help my issue. We have been doing a 4L80E conversion in our Holden VZ here in Australia and Chris has been and absolute gem by adding all of the parameters that we have been needing to complete this conversion. The TrailBlazer platform uses it too and the 24239927 TCM OS is the factory 08 TrailBlazer OS for 4L70E.
[ WIRE HARNESS INFO ], Visit my Check out what we have going on! EFI 58x™ GM Gen IV E38 ECM; EFI 58x™ GM Gen IV E67 ECM; CLEARANCE; Home > Harnesses & Connectors > Automotive Connectors > Connector Pigtails.
I loaded a 2013 corvette tune and a 2008-09 Express van tune. This is important because there is no direct sensor on the vehicle that has the ability to measure how much Torque the engine is producing. These tables are designed to act as a target for what the engine should be making for Torque. 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. E38 computers were the most common among naturally aspirated factory engines, but forced induction factory engines (LSA, for example) were equipped with the E67 typically, a cousin to the E38.
How is this all going? 2006 to 2007 brings us into the era GEN 4 ECMs, dominated by the E38. By looking at the Driver Demand Tables, the ECM can map the amount of Torque at a given RPM or Vehicle Speed. The problem went away after loading the correct OS into the ECM (one designed for the 6L80e). The 08 Grand Prix runs an E67 ECM with OS 12618164. PAY ATTENTION, for whatever reason, TRUCK and CAMARO have two pins swapped on gas pedal, D and F . For example, the Mass Airflow Table was split in half. I put a 6L80e (with its T43) behind an E38 ECM with an OS designed to work with a 4L60e/T42. How different are the RWD vs the AWD Trailblazer SS ECM and TCM files? In the early years of this computer, they did control a few LS2 engines, but they are primarily used for LS3s, LSAs, LS9s, and V8 truck and SUV engines. Sign up to receive updates and news from EFI. I don't want to sound pushy because the simplicity of a th400 is also compelling but the durability of a stock 6L80 is starting to get proven and if you have to build a th400 I think the price of a 6L80 starts to get compelling. [ HOME ] It will require the re-pinning of a few wires in the harness, but that is something done with relative ease. When prompted, save the file under a new name something like "XYZ_2bar.bin". What is the easiest way to do that? videos - E-Mail: A ‘VE Table’ is one of two methods used to control fuel delivery, typically the secondary method with the primary being a MAF (Mass Airflow Sensor). 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. Below are the ECM Connectors for 2008 vortec 5.3L I know the H3 Alpha is getting a 5.3L V8 and I assumed the 4L60E POS, but hadnt heard the Coly/Canyon is... Yep, they are actually doing it. Everybody loves the GM LS Platform; but as much as we hate to say it, the LS is dead… and in its place lives the LT Platform. E40s are strictly found in 2005 and 2006 LS powered cars. Note: Removing all of these will sensors, EVAP system, then you will not want to remove those components. For this reason, GEN 5 control modules need specialized attention when it comes to tuning them, which we address in our GEN 5 courses.
NOTES: This COMPLETE controller kit from PSI includes everything you need to get … By looking at the Driver Demand Tables, the ECM can map the amount of Torque at a given RPM or Vehicle Speed. If it is 2017 or newer, then it is an E92A. For the most part, things worked fine, but there was one big bug- the engine would go into reduced power mode every now and then. This makes the Pontiac GTO one of the most prime examples for this computer. The E67 is nearly identical to its E38 companion with the exception of the utilization of two supercharger tabs in the software, one located under ‘Engine and Airflow’, the other located under ‘Engine and Torque Management’. 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. 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. ©2020 The Tuning School, Inc. All Rights Reserved. These modules are the more desirable versions of the preceding P01 due to a processor upgrade performed by GM. Below is an example of a GEN 3 VE Table. Removed Vats and took out the rear ox sensors and all purge items. Rumour has it that the 6L80/6L90 may not be quite as strong as a 4L80E or a built 4L80E... can rumours be trusted...?
Tech Tips - Mechanical Issues Causing an Idle Problem This computer was the testbed for GM to start experimenting with the controls they would implement in the GEN 5 control modules paired with the direct injection V8 lineup. I don't want to sound pushy because the simplicity of a th400 is also compelling but the durability of a stock 6L80 is starting to get proven and if you have to build a th400 I think the price of a 6L80 starts to get compelling. There are several weird and quirky things that GM was trying out in this computer that only lasted a few years. BLOCKS HIGHLIGHTED LIKE THIS, ARE WIRES THAT ARE NEEDED, AND GO TO EXTERNAL CONNECTION FOR STAND ALONE I have also highlighted the 6 wires used to connect to the gas pedal. The Trailblazer swap is an interest of mine as well. YouTube channel for How To However, when the E40 was released, it introduced a flow rate table that has a limit of 64 pounds per hour. Virtual Torque is a system that calculates how much Torque the engine is making at a given operating condition.
Should be similar for 4.8L 6.2L applications. NEEDED. View Full Version : Transmission swap in E38/E67 vehicle.
BLOCKS These modules are the more desirable versions of the preceding P01 due to a processor upgrade performed by GM. Hi guys, Need some help, looking for a tune file out of any car that has an E38 ECU, T42 TCM and with a 4L80E Transmission. True plugin solution. The primary difference between the GM GEN 4 and GEN 5 ECMs is Torque management. These computers were not phased out until 2016. Car starts and runs great, but when putting it in reverse or any gear besides park or neutral, it will idle up 300 rpm higher than programed for about 6-8 seconds than the idle it is programed to. The E67 computer was introduced In 2009 with supercharged 6.2 liter LSA in Cadillac CTS-Vs and LS9s powering the Corvette ZR1s.
I purchased and tuned it with HP Tuners Pro.
This attribute is desirable to performance enthusiasts with the increasing popularity of E85 as a race fuel alternative. This is a much more robust system which was required when the engines evolved to include features such as variable camshaft controls.
APPLICATION: 2007-2008 Vortec Truck 6.0L/6.2L Engines PARTS INCLUDED: Complete Engine Wiring Harness (4 Wire Hookup), Programmed Engine Controller (E38 ECM), T42 TCM, Accelerator Pedal, LS3 Cartridge Mass Air Flow Sensor, Mass Air Flow Sensor Bung, Oxygen Sensors (Qty. For some reason they are sticking a 4L60E in it. While the E38 has these tabs and settings, they are not used in its applications. The ECM just needs to send RPM and load info to the TCM so I don't think the e38 cares between the 90e and the 80e.
