    Calling on the VIC brethren. E85 content lately sub par, or is it just my gauge

    Hi,

     

    E85 sold in Australia does not have to be 85% ethanol, it can actually be in the range of 70%-85%. If you are filling up at the servo it is going to be very hit and and miss - both with regards to ethanol percent and fuel quality especially at the one that sells E85. I would invest in a means to detect water in your fuel as well - with petrol, water will not mix and will sit at the bottom of a tank, but water will mix with ethanol. With E85 the water can form an azeotrope and become "mixed" in a sense. Maybe consider buying by the 205 L drum from a racing fuels place? They should be able to guarantee quality and content.

    "The autogas fuel standard describes liquefied petroleum gas (LPG) suitable for motor vehicles. Petrol sold in Australia may contain up to 10 per cent ethanol (‘E10’). The Ethanol E85 fuel standard describes a fuel blend consisting of 70–85 per cent ethanol and 15–30 per cent petrol"

    Often you'll have a full team of engineers, each working on calibrating only one part of the PCM, they often don't understand what the other ones are doing as they don't have the time to learn everything.

    My (non) understanding of it is that they designed basically as flow charts, which in turn each part of the flow chart is a reference to another flow chart, and so on and so on and so on until you reach flowchinifinity. It's quite impressive what PCMTec has done, it's one thing to figure out how to download and upload the data, but to then go on and define it and make use of it was likely not an easy process.

    Ive just tried that, made no difference.
    what else could it be?

    this car has been through multiple tuners before me, there were so many weird changes I don’t understand. Should have just started from stretch but didn’t want to until I knew why all the changes were made. They also changed everything in auF0262 to 0 and auF0261 to 1 for some reason. 

    This could be the issue, you can disable/modify ETC as a method to limit torque there, if auf0261 is all set to 1 it is allowing the PCM to choose from every possible torque reduction option so it is choosing ETC in this case to limit engine speed. (I think, somebody correct me if inaccurate). This post has better info on those params.

    Not fussed about making more power, car is probably as powerful as it can get without forced induction. Has full extractors and pipes all the way back, had a big intake but returned to stock as moved to sunny melbourne, plus throttle controller and short shifter. I am more interested in learning about how PCM's work and seeing what comes from poking around as well tinkering with random things like cutting the AC compressor clutch automatically @ full throttle and air cooling the engine via cylinder cutout in an overheat condition. Random but yep.

    Sorry hit post button early

    Am considering purchasing a license. Am I in the ballpark with the basic needs required for getting started.

     

    • Windows 10 Laptop 8g ram ssd hard drive
    • Tactrix Interface
    • Wideband o2 sensors

    I have a Boss 5.4 (302) with a pcm that was flashed by an SCT tuner by BlackMac Performance in WA, who have since shutdown, I think the PyCM is locked, is this an issue? I cannot see any config or as built data for it on Forscan, only have the option to reset adaptations.

    Also concerned about nuking my engine, common sense aside are there inbuilt warnings in the software that suggest a value is too high or low?

    Hey Guys

     

    Many years ago I did a whole lot of work like this on BA, BF Falcon and SX Territory - reverse engineer CAN Arbitration messages/ IDs.  I didn't do so much on the PCM side like you guys are doing, but I did a whole lot on the other modules - PAM, RCM, IC, ICC, HIM etc

    I've just started some similar work recently on a 2007 WQ Fiesta XR4.

    Is there any appetite for me sharing any of my data? Or is this mainly a thread with Focus in PCM broadcasts...?

    I'm kinda on the hunt for a forum or message group with people doing similar reverse-engineer analysis on Ford messages. There's not much around. Some US based F150 guys, one on a Focus which, depending on the model, is likely to be very similar to the WQ Fiesta and BA Falcon, as both used ECU architectures that were derivatives of the original MkI Focus.

    I have been using a socketcan to map out the the CAN in my FG mk1 - sheet is here https://github.com/jakka351/FG-Falcon
