The MegaSquirt Project has experienced explosive growth other the years, with hundreds of new MS installations occurring every week - a phenomenal success! MegaSquirt has been successfully used in all aspects of Internal Combustion engine applications including R&D, Industry, Race, and Research. The MS project has transformed itself from a simple R&D project into a full-featured mature engine control system. To reflect this the support structure has also changed to meet the needs of MegaSquirt Users.
Moving forward, the R&D forums for MegaSquirt project are in a read-only mode - no new forum posts are accepted.
However the forums will remain available for view, they still contain a wealth of information on how MegaSquirt works, how it is installed and used. Feel free to search the forums for information, facts, and overview.While the R&D forum traffic has slowed in recent years, this is not at all a reflection of Megasquirt users, which continue to grow year after year. What has changed is that the method of MegaSquirt support today has rapidly moved to Facebook, this is where the vast majority of interaction is happening now. For those not on Facebook the msextra forums is another place for product support. Finally, for product selection assistance, all of the MegaSquirt vendors are there to help you select a system, along with all of the required pieces to make it complete.
Vehicle: 97 Ford Mondeo Wagon Engine: 2.5l Duratec V6 24V, no mods Injection: Port injection, 17lb injectors, stock injection system Ignition: stock 36-1 trigger wheel with EDIS6 & MS2 Description:
Now equipped with a MS2V3 connected using the fabulous EEC-V-adapter-board by MegaScott. Final target is to modify the MS2 so it controls petrol, CNG and LPG injection for the car. The car is equipped with everything needed for that already, right now LPG and CNG are controlled by two Landi Renzo Omegas systems which use the injector pulses of the petrol ECU as input. And surprisingly: this also works with MS2, even though it doesn't do sequential injection (and the Omegas are told to be sequential only). But some day I'll have it all controlled by MS2, 2 sets of injectors, 3 fuel sources, 3 fuel- and timing tables... I hope it all fits ;-) I'll be using MS2extra for my development

Forgot to update. The MS is controlling all 3 fuels natively for a long time already (running since December 2006). Works really good, but still have difficulties with my two LC-1 controllers. Most of the time they refuse to operate and throw error codes, especially if I go to higher loads (more than 3500 rpm or WOT). I'll replace them with a different controller soon and then hopefully can complete the setup and go for a dyno.
Firmware is now based on MS2Extra 1.0.0, but adopted to have 3 dual bank ve tables, 3 afr tables and 3 advance tables. Also of course an input to switch between the fuels, gas temperature sensor and soon also gas pressure sensor.
I have a cougar with a 2.5 duratec in it, and it runs VERY rich stock. I was thinking about putting a MS2 in it. Any chance I could get some more info on your setup?
Is it possible to get the car running with MS if I was to just make a jumper harness from the MS to the stock harness? Or would I have to run new wires to the motor? Did you remove the secondary throttle bodies?
I'm wanting to try to get this running with the least amout of headaches as possible.
No new cables necessary, I'm using the EEC-V-Adapter by MegaScott. I've connected an EDIS to it internally, but you can also use the MS directly to control ignition, all needed signals are there. I left the secondaries in, as they're a great improvement in the lower revs. Tried it with all time open secondaries, but the engine had noticable less torque below 3500 revs. So I connected the IMRC to a spare output of the MS and control the secondaries that way. You just have to ground one wire to open them, or leave it floating to close them.
So if you want it simple and reverseble, ask MegaScott for one of his great adapters, get an EEC-V from the scrapyard or ebay which gives you the case and the connector, and then enjoy using MS
I used factory setting, so 6950. My MSQ wont help you, as I'm using a modified firmware to drive my car with those three fuels. I can send you the petrol table which you can import into your msq, but I'll need about 1 or 2 month to tune that table, right now I've only tuned CNG and LPG (no one drives petrol if he's not forced to ;-)) and I'm waiting for the second JAW before I switch over to tune petrol. Right now it works at idle and the lower cruise regions, but not at load (much to rich). I can also send you screenshots of the other settings once your setup is ready.
For the adapter send an email to Megascott (his address is at www.megaefi.com. I got mine for free, as it was a beta board at that time.
