Note that for 2.9 Code, the first thing you must do after loading code is set the ECU Type (under 'Fuel Set-Up/General') to match your hardware (MS-II™ or MicroSquirt ® controller), MegaTune will not let you change anything else until you do this. Since it is DIY, it is much less expensive than many other. It performs many of the same functions as the factory Motronic unit in the e28 but allows the end user to adjust different parameters (fuel, timing, idle speed, etc) affecting how the engine runs.
#Megatune timing software
This document covers the use of the 2.9 versions of embedded software (aka. Megasquirt (MS) is a DIY programmable standalone electronic fuel injection (EFI) computer. These options can support odd-fire through the OddAng input. N-0 Wheel w/ Falling Crank Sync or N-0 Wheel w/ Rising Crank Sync same as 2,3 but crank synch on 2nd input, no missing teeth. Dual Inputs, Timing from 1 cam tooth same as 1 except timing signal from 1 cam tooth, 2 cyl only. in these circumstances, the engine will misfire and skip cylinders. Just about any computer that is capable of booting Windows 95 (or better) will be fast enough, but get the fastest laptop computer you think is reasonably priced, obviously. MegaTune allows you to manage data for multiple MegaSquirt. Note: When you connect pin 12 to IGt pin on the igniter, you might the tach on the dash jumps erratically, the car misfires, sometimes timing will stay at 10º BTDC, and sometimes it will advance to 30° BTDC, no matter what you set in the timing menu in MegaTune. A USB/serial converter may work, and many people have reported that they have been successful using a USB-serial adapter. FirstFives Dictator Posts: 849 Joined: 5:00 PM Location: Virginia Beach, VA. Does this look right to you guys I also dont see a box for BTDC Thanks.
#Megatune timing serial
You also need Windows 9x/Me/XP/Vista/7 on a computer (a laptop or notebook computer if you want to tune in the car) and a conventional serial port to communicate with MegaSquirt-II™. But I seem to have a different version of megatune. (Version 2.25 or higher is needed to work with MegaSquirt-II™). The Windows 9x/ME/XP/Vista/7 software application you use to tune and configure your MegaSquirt ® or MegaSquirt-II is either Tuner Studio by Phil Tobin or MegaTune by Eric Fahlgren.
