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. Need some help on 09 5.3 / 6L80e and e38, transmission from 6L80e to 4L80e wiring schematic diagram, If this is your first visit, be sure to 4L80E Transmission Connector Pigtail for electronic transmissions. I loaded a 2013 corvette tune and a 2008-09 Express van tune. E85 fuel, methanol injection. HIGHLIGHTED LIKE THIS, ARE WIRES THAT CAN BE REMOVED FROM PCM CONNECTORS, NOT 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. In the P01 computers, the MAF table typically reads from 1,500 to 12,000 Hertz. This means Corvettes, Camaros, trucks, and SUVs from 2016 and newer all have GEN 5 computers. One of the primary differences between the GM GEN 3 and 4 ECMs are how they estimate airflow using VE Tables. Should be similar for 4.8L 6.2L applications. 2). The Injector Flow Rate Tables of the previous ECMs (P01 and P59) have a flow rate limit of 254 pounds per hour. Start with a stock or existing tune from the PCM. These tables are designed to act as a target for what the engine should be making for Torque. Below are the ECM Connectors for 2008 vortec 5.3L harness. Upgrading fuel injectors to something with a higher flow rate is a must in most performance applications. [ HOME ]    While the E38 has these tabs and settings, they are not used in its applications. Corvette C6 (GM E38 ECM) Corvette C6 (GM E38 ECM) 2006 - 2013. All images within this website are property of EFI Connection, LLC. The Virtual Torque system enables the computer to achieve a target, not just limit the power output (like the GEN 4 ECMs did). Just like the E40 was the hybrid test bed for the coming GEN 4 computers, the E78 seems to be the test bed for the GEN 5s. The 08 Grand Prix runs an E67 ECM with OS 12618164. E38 ECM (58x) 2007-Newer GM ECM. Rumour has it that the 6L80/6L90 may not be quite as strong as a 4L80E or a built 4L80E... can rumours be trusted...? One joke that’s prevalent among experienced tuners is that “if you are going to tune a '97 or '98, then you better have a pile of spare computers sitting on the workbench.” For these reasons, we recommend upgrading to a 0411 if you are going to be adding performance modifications to a '97 to '00 LS powered vehicle. I really appreciate any response in advance. I purchased and tuned it with HP Tuners Pro. HIGHLIGHTED LIKE THIS, ARE WIRES THAT ARE NEEDED, AND GO TO EXTERNAL CONNECTION If it is 2017 or newer, then it is an E92A. The 0411s are also much more robust than their "fragile" 1997-2000 predecessors which are easy to damage while writing tune files to them, rendering them permanently damaged. The TrailBlazer platform uses it too and the 24239927 TCM OS is the factory 08 TrailBlazer OS for 4L70E. PAY ATTENTION, for whatever reason, TRUCK and The last hoorah for the GEN 3 computers is the E40 control module. This is more than enough for almost every application. Powered by vBulletin® Version 4.2.5 Copyright © 2020 vBulletin Solutions Inc. All rights reserved. Just finished a LS3/4L80E swap into a 68 Chevelle. 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. What sets the E78s apart from their GEN 4 counterparts is the Torque management controls. Below is an example of a GEN 4 VVE Table, represented using air in grams/sec/sec, temperature corrected to Kelvin, as well as multiple camshaft angles. There is at least one other swap in progress that I know of but, it's coming along slow. If the GEN 5 computer you are dealing with is older than 2017, then it is an E92. GRAY, Application: 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. These images are not to be used for marketing purposes on any other website. The VE values in the table represent a ratio of how full (of air) the cylinders are, compared to their theoretical maximum. It's an all wheel drive Trailblazer SS. Requires an EFI 58x™ SBC Conversion. GM is really doing that? However, when the E40 was released, it introduced a flow rate table that has a limit of 64 pounds per hour. This attribute is desirable to performance enthusiasts with the increasing popularity of E85 as a race fuel alternative. 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. True plugin solution. I am jumping ahead, there are still no '08 E67/T43 setups that would work I don't think right? Some OS/cal pairs work better than others. EFI 58x™ GM Gen IV E38 ECM; EFI 58x™ GM Gen IV E67 ECM; CLEARANCE; Home > Harnesses & Connectors > Automotive Connectors > Connector Pigtails. [ WIRE HARNESS INFO  ], Visit my Supports 4L60E/4L80E, 6L80E/6L90E, and manual transmissions. Because of their widespread use for so many years, odds are you will spend much of the time working with E38s. He checked my stock files against his and there was no differences in the ECM or TCM files. We accept all major credit cards, plus Paypal. I don't know if that was tuning related or what though. When prompted, save the file under a new name something like "XYZ_2bar.bin". The computer can then seamlessly change the fuel output and spark advance on the fly to instantly compensate for a change in Ethanol content. 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. Just finished a LS3/4L80E swap into a 68 Chevelle. The GEN 3 VE Table was a traditional table based on RPM and MAP. How different are the RWD vs the AWD Trailblazer SS ECM and TCM files? These computers were not phased out until 2016. PAY ATTENTION, for whatever reason, TRUCK and CAMARO have two pins swapped on gas pedal, D and F 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. :D I know it has been done in a pickup truck(E38) and there were a few ECM/OS/module issues that I am not sure I can work through with the E67 versus the E38. Truck is a Stock 5.3L 2008 Silverado, Procharger with a 4L80E Trans. By looking at the Driver Demand Tables, the ECM can map the amount of Torque at a given RPM or Vehicle Speed. However, this also makes it the “red-headed stepchild” of GM ECMs, as it is known amongst tuners. YouTube channel for How To I purchased and tuned it with HP Tuners Pro. 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. Application Procedure (E38 ECM) To apply the enhancement to your PCM please use the following procedure. While P59 computers closely mirror their P01 cousins, something interesting to note is that they are one of GM's first Flex Fuel capable ECMs. It'll work out, let us know how it goes... :cheers: I put a 6L80e (with its T43) behind an E38 ECM with an OS designed to work with a 4L60e/T42. Yes the T43/E38 pair tend to be very fussy when you least expect it. Sign up to receive updates and news from EFI. 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. FOR STAND ALONE. While fueling and spark control are the same for GEN 5s as they are for GEN 4s, the real difference comes in the form of calculating how much Torque it should be making and then what the computer does about that calculation. I put a 6L80e (with its T43) behind an E38 ECM with an OS designed to work with a 4L60e/T42. There seems to be so much heresay as to what options that I have right now to get this running. ETC. 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. The Express Vans use the same OS for 4L80E, but are E38 based with ECM OS 12617631. 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. Below is an example of a GEN 3 VE Table. Should be similar for 4.8L 6.2L applications. We are constantly updating our blog with new content. Just like the before mentioned Virtual VE Table, HP Tuners created a Virtual Torque Editor that gives you a physical table to modify in order to change data in the system in the background. 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. This really means that the computer takes real inputs like RPM and MAP, but then based on other inputs such as camshaft position and manifold runner position, it calculates a value. 2006 to 2007 brings us into the era GEN 4 ECMs, dominated by the E38. The early E38s mirrored some of the bad habits from their E40 GEN 3 predecessor, but by 2010 the idle, fuel and spark controls were some of the best GM had created to date. The computer knows that at a given Hertz value, a specific amount of air is being drawn into the engine. Below are the ECM Connectors for 2008 vortec 5.3L harness. I have been looking for adaptive idle but can seem to find or know if this will actually will help my issue. 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. I am planning an LS3 swap into my 240SX and ran into a roadblock. October 26, 2020, Tech Tips - Logging Two MAP Sensors THEY WILL GO DIRECTLY FROM ECM TO A PLUG, (SENSOR, SWITCH, DEVICE The LS3 I am looking at right now is from a 2010 Camaro. Does the 4WD have a lo 4 setting? connect to the gas pedal.
