The Complete MEFI5 ECM Solution - Tuning, Data Logging, Diagnostics for MEFI5, 5A, 5B Our Marine EFI (MEFI) Scan & TuneTM system allows you to download the internal MEFI programming to your PC or laptop with our MEFI5burnTM program, change the operating parameters of the controller, and then reprogram the controller with your modifications. It also allows you to view all of your sensor systems in real time and log the data for later viewing, in addition to seeing which malfunction trouble codes, MALF's, have been set. Some competing systems will only allow you to monitor the performance of your boat or off-road vehicle's engine controller and reset engine trouble codes. Other costly packages force you to use an inconvenient hardware dongle or key, and only work with a few versions of the MEFI ECM series. Those days are over! The MEFI5burn Scan & TuneTM package comes complete with everything you will need to interface to generations of the MEFI controllers, including MEFI-5, MEFI-5A, MEFI-5B: MEFI5 Interface Box. This has the electronics necessary for the CAN-based communications system A USB cable. This 6-foot cable has a standard USB connector to plug into the PC or laptop and a Mini-USB connector to plug into the MEFI5 Interface Box A Vehicle cable. Two versions of the cable are available, one for the flat 6-pin Marine OBD interface or a standard OBD2 connector. These cables are about 10 feet long. Along with the 6-foot USB cables this allows 16 feet between the PC or laptop and the vehicle's diagnostic connector. A CD containing all the software you need to do both monitoring and tuning of your controller. The following table will help you determine which MEFI controller you have. On the bottom of the controller is a sticker with a part number. The GM part numbers and MEFI ECM's are listed here: GM Part No. MEFI Type 12597744 MEFI-5 12607802 MEFI-5A 12618020 MEFI-5B 12628090 MEFI-5C 12635518 MEFI-5D For Tuning the MEFI1-4B family, please see MEFI Scan & Tune Monitor your MEFI 5 system Our new MEFI5 Burn software package is used for doing engine monitoring, data logging, and malfunction trouble code reading. Our custom-designed interface cable allows you to do real-time monitoring and data logging of the MEFI engine controller. MEFI 5 Scan & TuneTM supports the following controllers: MEFI Type Supported MEFI 1 - MEFI 4B NO MEFI 5 YES We are currently working on adding MEFI6 tuning capability to our MEFI5 Scan and Tune system. MEFI 5 is the newest generation of MEFI engine controller in widespread use. Download and Burn A critical step in the tuning process is the ability to upload and download programs between your MEFI controller and your PC or laptop. Our new software, the MEFI5burnTM program, in additon to thescan function is also specifically designed for MEFI controllers to do that data transfer. This MEFI5burnTM software can do both the download and critical upload (programming) functions. It works with the common automotive .bin file format. The MEFI5burnTM program allows you to enter a password on password protected calibrations, if you know the password, or if you do not know the password, completely blank out the internal memory of the MEFI controller and upload a fresh base tune to start your custom tuning process.

Tune Your MEFI Controller TunerProRT 5 is a free, donate-if-you-like-it tuning platform aimed at making tuning easier and cheaper. TunerPro started life as GMECM Edit, and debuted in early March of 2003. TunerPro has since grown into a very robust tuning tool. We have developed two versions of control definitions to work with TunerPro, the Standard Edition and the Professional Edition. There are hundreds of parameters that can be tuned in a MEFI controller, however, only a handful are typically used. We have selected this typical parameter set for the MEFI 5 Scan and Tune Standard Edition. The full parameter set is overwhelming for all but professional tuning applications, so for those pro users, we have MEFI 5 Scan & TuneTM Professional Edition. For complete details and screen shots of TunerPro, see our TunerPro page and Mark Mansur's TunerPro.net webpage Click for TunerPro screenshots and detailed program info. Monitor and Data Log Your MEFI Controller ScannerPro is a free, donate-if-you-like-it monitoring platform also done by Mark Mansur. Mark has done a great job of creating a simple to use and very detailed monitoring and data logging framework We have developed 4 versions of control definitions to work with ScannerPro, MEFI-1, MEFI-2, MEFI-3, and MEFI-4. There are many parameters, flags, warnings, and MALF trouble codes to be monitored and logged for each generation of the MEFI ECM. For complete details and screen shots of ScannerPro, see our ScannerPro page and Mark Mansur's ScannerPro.net webpage Click for ScannerPro screenshots and detailed program info. Ramjet 350 and Ramjet 502 Reprogramming We have the capability to reprogram the calibration and tune of your Ram Jet 350 or Ram Jet 502 MEFI ECM. We do this Ramjet tuning on a mail in basis, and charge $200 for basic tuning. Don't suffer with a poor running Ramjet any longer! Custom MEFI tuning We can custom tune your MEFI controller, program your ecm remotely, anywhere in the world, and do MEFI Calibration Translation. See our custom and remote tuning page. MEFI usage and applications: Delphi Delco Electronics manufacturers the finest engine controllers in the world, and their development, testing and manufacturing capabilities are unrivaled. The MEFI line of controllers has evolved over the years and always has been on the cutting edge of engine control technology. The MEFI has been deployed in myriad applications from marine to industrial to racing to crate engine packages. This controller has enormous flexibility and the number of internal engine control parameters is staggering. To date, this marine ECM controller has faced challenges for custom deployments and modification because of the lack of a competitively priced and widely deployable software and hardware solution. Now, the only question is if you want the Standard or Professional version of the MEFIburnTM package.
