As my low run-hours Evinrude FICHT 1999 225 HP (E225FPXEES) many years I have progressively worried that when we have a catastrophic ECU failure that renders it incompetent at interaction using the Evinrude Diagnostics Software that i am going to don’t have any initial ECU database to source-clone and change in to a new/replacement ECU.
I’ve use of a complete up form of the Diagnostics SW but do not see any features for “backing up” or “saving” a current ECU non-volatile memory dataset. These E-TEC that is early precursor didn’t have lots of ROM history to protect aside from run-time, Injector Serial #s-Coefficient-Sets, ECU/SW Version, different Max-Sensor Historiws and RPM-Range Run Historgram etc.
The fact I would ike to protect significantly more than any such thing would be the Injector information.
The only function we see into the diagnostics sw may be the power to do an “In Memory Transfer” from a “Donor ECU” to a “Recipient ECU” – which needless to say presupposes that the donor is operable sufficient to link and communicate to learn information into memory then move to a different ECU. I will see why “Evinrude” (OMC/BRP) could be reluctant to provide the capability to move to an export/backup file to stop anybody from gaming the run-hour SW counter (resetting the odometer as they say) to obtain guarantee claims on machines and ECU’s which are away from their run-hour warranty – however these are now actually all OLD Engines & most of us is supposed to be making use of salvaged components to help keep our engines(esp that is running).
At this time the best way we see to have a duplicate from memory is to try using a low-level debugger to scan memory to duplicate a memory image and make use of hacking techniques to obtain information as a file that may at a later time be employed to emulate this ECU to ECU donor/recipient transfer capability from a file.
Anyone understand of ways to do the things I have always been asking in a hassle free way or having a computer pc pc computer computer software emulated “recipient” ECU to a target information to that particular dataset enables you to re-transfer to a real ECU at a subsequent date making use of the current diagnostics?
Undoubtedly, there’s surely got to be solution to fully grasp this information in the eventuality of a total ecu fail ( or perhaps the more recent EMMs)?
Simply attempting to be proactive since we heard its close to impractical to have the injector data from BRP of these old models. Ideas?
really the only other method i really could see around it really is to obtain an individual who’s authorized to reverse engineer amolatina agency the injector coefficients by releasing an app that is reprofile-ing a lab work bench testbed to curvefit brand new ” because is” coefficients that tend to be more present for the worn-in state associated with injectors. That way brand new ECUs could just import the injector data straight into the ECU/EMM just as if changing the injectors. Really i will be type of astonished EPA will not need recert of injectors with updated parameters after each 1000 hours of run time or more (appears like a money that is great solution in my experience in addition).
Got myself into two various highly correlated/related topics right right here.
Any ideas or insights?
There is not ways to save the injector just coefficients as a file?
Possibly obtain a dealer to obtain the coefficients emailed for you and simply save your self those files.
Wow – sorry to start up old wounds on that bad experience. Had been really searching for some value added opinions here.
Historically I am proper though in the event that you go through the development for the whole notion of changing carbohydrates by having an in-the-loop computer regulating gas flow to achieve greatest HP/Torque and fuel efficiency dynamically in real-time by micro metering gas distribution. FICHT technology ended up being method in front of its time for outboard engines and revolutionized the market that is whole albeit maybe perhaps maybe not prepared for prime-time and rushed into solution too quickly. I did not suggest to find yourself in the semantics that are subtle faith wars of DI vs EFI gas distribution mechanisms.
But had FICHT maybe maybe maybe maybe not been introduced as being a forcing function to get other manufacturers to start out doing exactly the same genre of concept the technology could have never got out from the lab and bootstrapped. Evinrude includes a good technique to push the EPA angle whilst the single most readily useful low emissions outboard engine on earth during those times by touting it self whilst the single provider of marine engines certified to use in environmentally sensitive and painful Lake Tahoe etc.
BRP basically came in as being a White Knight to drive in to the technology gear-shift and capture very very very very early share of the market that Evinrude/OMC broke into with a fairly strong energy.
