    LightbulbrusEfi - open source ECU

    I know there is some interest towards aftermarket engine control units here so wanted to present mine.

    I am playing with this for over three years now, back in 2014 it looks like this



    but since then some progress was made and now it looks more like this



    that's using a connector and case shared by mazda and toyota back in the 90s

    This ECU is pretty drive able now - couple of lemons races and getting closed to 10000 road miles



    This May I will race this Opel



    and hopefully later that would be rusEfi vehicle #35

    Looks like you need a driver that has more confidence in their ability to shift gears.

    Are you running injection on an Opel with the EEC-IV or just spark? I just got into Ford stuff this last year with my Volvo 5.0 swap. I have a whole EEC-IV setup in a box, I ran my '98 on EEC-V from the donor Explorer.

    I'm not opposed to running your ECU, I just already have Megasquirt. I think if you want to offer something to Opel guys, the easiest way to make it happen would be what I laid out in the other thread.

    Have a procedure or product to lock out the distributor mechanical advance and run a pertronix ignitor as a VR input to your ECU.

    Have an onboard high current coil driver to fire the coil directly.

    Your injector drivers would need peak and hold or PWM to run low-z injectors used in GM TBI, GM TBI being the easiest and most common junkyard package to retrofit.

    I really prefer underhood packaging for ECU, like the Microsquirt. Simpler wiring, smaller holes drilled.

    I started with a megajolt controller for spark.I was running downdrafts at the time.
    Then added the EEC-IV to handle the fuel injection side.

    I have a Quarterhorse and I'm using EEC Editor. I'm undecided which direction I want to go. My Explorer ECU isn't the best supported, but it's the only OEM calibration for a 5.0 with EEC-V/OBD2. I need to pay some substantial money to get it dialed in. Either I need to get a custom SCT tune from a dyno shop (that's their recomendation), or get on a better supported ECU/strategy. I'm thinking of having a newer 4.6L ECU re-tuned for the 5.0. The SCT tune might be the way to go, but it's a pretty closed system. Though if it's done well, I shouldn't need to get in there and tweak things on my own.

    I have a 4R70W electronic transmission, also controlled by the EEC.

    WARNING! Thread sidejack

    The more people talk about this stuff, the more it becomes confusing.

    Juan said he was making a programmable distributor. I was all ears. I never got answers as to what we need or what all went into a package.
    Then there was the teaser about fuel control. I've been reading and not understanding much about all the acronyms and abbreviations.

    I'm not a dumb guy.

    So now there's more talk about this and that and acronym this and abbreviation that. And then Wrench comes in and NEVER makes any sense or helps out and people are talking to him like he has anything helpful to add.

    This is me confused.

    Look, I would like to BUY, for less than an inheritance, a system to run my coil and a system to run my EFI. Or both combined, or whatever. I need one that you can program with a GUI (graphic User Interface) so even a guy like me can add and subtract event attributes. Ideally, I'd like this to be on the fly but I'm OK with pulling over to the curb to make a change.

    And I'd also like my parts back that I lent to help build the system that's no longer being pursued/offered/engineered/whatever.

    I don't ask for much.

    Would it help just a bit to

    a) not discuss Ford EEC-IV HOWTO within this thread?
    b) not discuss systems no longer being pursued/offered/engineered/whatever within this thread?

    Just an idea

    As for the general sense of confusion, I do not have a plug-and-play setup for Opel GT

    Unfortunately rusEfi is only a universal ECU so whoever (if anyone) would ever want to try on an Opel gt, that would be a steep learning curve.

    That we are talking about with EEC, etc - is Ford's system. Reverse engineering an OEM's system is the least expensive way to get into EFI because it's all inexpensive junkyard stuff, but it was not designed for the end user to muck about in, and it's VERY confusing.

    Megasquirt is not the cheapest, but it WAS designed for the end user to fiddle with and reconfigure, nice GUI, auto-tuning, etc. The more to pay, the more R&D has gone into making it easier (FiTech, Holley, Haltech, FAST, and so on). An OEM system can be made easier to work with, but you're going to be paying for some more advanced software. Again, the R&D a person or company has put into making the black magic of fuel injection easy.

    Keep an eye on my Kadett thread, I'm doing EFI on it with Megasquirt in a simple but effective manner. I've run a GM V6 with TBI on Megasquirt, so it's not completely new to me.

    The steep learning curve is unfortunately the deal killer for most. The quantity of people who cross-over between gearhead and open-source developer are few.

    Obviously you do not need to be a software developer to use rusEfi - obviously no users write code, users are just using online tuning software (actually same as MegaSquirt - rusEfi and speeduino both are integrated with TunerStudio)

    but it's also obvious that having 1000? 10000? 100000? MegaSquirt installations on this planet helps them a lot so that's where we are trying to get more features for less $$$ because more modern processor allows that.

    No it's not all that confusing

    I am having fun with my Opel thats using a EEC-IV PCM.

    So a fast processor will allow better fuel control?
    Or are you going to add anti-lock into the system.

    Yes and no.

    Very little CPU speed is needed to control fuel - but the more speed, memory and input-output pins you have more features you can have and more user-friendly you can be. Emphasis in user-friendly - I am trying to make the device more usable, with same good fuel control.

    Our unit has knock decoder on board - I believe no MS device has knock detection? I could be wrong. Only most expensive MS units have SD card logging - ours has SD logging and an LCD for human-readable diagnostics in the field without a laptop.

    Let's do this, I believe it will work out better for everyone and James will not be on my case anymore.

    Send an email to support@EDCATL.COM with a list of the parts you sent in, I will return the parts to you and life continues.

    When the device is finished and properly tested then you can determine if you want one or not.
