Connected Bootstrap tool. Communications all good thanks, However the software only allows me to update matching maps. As above, the map is for a e225 where my engine is e250. Is there a procedure to upload the new, different and correct mapping?

Hi Sam,
Sorry I don’t have the knowledge to answer your last question. Way above my pay grade and you’ll need one of etecownersgroup’s very switched on techs to provide an answer.
I may have misunderstood what you’re trying to do but if you’re trying to load an engine map from a 250 into an EMM off a 225 then from what I’ve read this can’t be done. I would think you would need an EMM off a 250 to get it’s engine maps for a start and even then you’d need a passcode that’s only available to Dealers.
GEB

Ps Techs please correct me if I’m wrong.

Thanks GEB,

Found a questionable fuel injector on cylinder 1. Now cleaned, overhauled and replaced. Engine now firing well on all 6 cylinders. Have never been able to reproduce the engine cut-out while on the trailer. Plan to take it out this week for trial. The question to ask is: would the EMM shut down the engine if it only fires on 5 cylinders, ifso could I expect some kind of alarm from the EMM. Anyway I have updated my e225 EMM software for my e250 engine to give it a test under load.  Let's see.

Hi Sam,
After you test run if you could pull and post the latest Engine History Report the techs may be able to give advice based on the fault codes in the report. Rereading your post it appears that your engine was going into SAFE mode. A very common reason for that is “Overheating”. Are there any recent overheat codes stored in the latest Engine Report. ?
Cheers
GEB

Thanks GEB,

I have put the initial report on first post. Yes I have had a history of overheating but everytime I get the alarms accociated with it. The overheating problem is now solved and I am always monitoring the live temperature via dashboard. However not able to see the EMM temperature but as stated before when I did overheat I always got the correct alarms. When you say SAFE mode is that when you can only get reduced power (which I was getting) or does it mean engine shut down?

Hi Sam,
SAFE Mode can mean reduced RPM or if situation persists then it’ll shut down. EG (my experience) with an overheat the engine initially went into SAFE Mode, reduced rpm, but in my attempt to make it back to the ramp I overheated it to the point where it stayed too hot for too long and it shut down completely and wouldn’t start until it cooled down enough. No doubt you had a similar experience.
IMO anytime a fault has the potential to permanently damage the engine it will shut down to protect itself from that damage BUT there’s plenty of suitations where no fault code is “thrown” and the engine won’t shut down even though damage will result. The classic example of this is a partially/ blocked injector causing lean running.
Re a History Report, I was referring to you pulling and posting a New Report after your latest test run as it may (now) have different fault codes recorded or not.
I’m not a tech and can only talk generally about what is for you a specific problem and you really need one of the “techs” to chime in here.
Cheers
GEB

Thanks GEB,

Met the "Technician" this atfernoon at the boat and confirmed that the injector is still not doing its job. He says he has a used one in his workshop that he will fit it. After reading the service manual I see that the serial number and coefficients for the replacement injector have to be up loaded from file on a disk supplied with the injector into the EMM. Without any support for Evinrude here in Oman, not sure I can get hold of this file. I Will start a new post on this topic shortly to see if it is possible to obtain the original file against the serial number but first I will check the serial numbers of each injector against serial numbers uploaded into the EMM. With the incorrect engine setup (e225) against my actual engine (e250) I am expecting them not to match. Let's see.

You have not had a floppy disk with injectors for many many years so if no check sum on this second hand injector it will be old. Something strange too if the EMM is loaded with different HP map-can not happen due to HP mismatch when one tries to do this with Ev diag. Post a history report.

No active errors in latest history report to cause SAFE mode.
Post up a snapshot of the Monitor page in the Diagnostics software when the motor goes into SAFE mode.  also the captured last 2 minutes immediately after or during SAFE mode, which is attached to the Engine History report at the end.

If the EMM/motor is still going into SAFE mode, I would surmise that the present EMM has one or more sensor inputs damaged by EMM overheats caused by cooling tube problems.

Do you have the Engine Data file from the original EMM E250DCXSDR Engine Serial Number as 05141287?  If so, may be able to force the 250 data file into the present EMM by running the EMM recovery routine in the software and forcing the firmware in after coldtest.  See diagnostics Help file.

Or buy a new EMM from Joe at Barnacle Bills programmed for your 250 model and serial #.

Hi Steelhead,

I can not simulte the shutdown on the trailer. The engine cuts out with engine speed above approx. 2K rpm only on water I have replace both fuel pumps and tried with a separate fuel supply..No difference . Not sure if it going into SAFE mode as no alarms are seen. I do not have the original engine data file. As mentioned above I am in Oman. Purchasing a New EMM from BB's is not that simple and has to be the last resort.

Don't see any causative factors for 2000 rpm limitation in the EMM data you last posted.

Fuel restriction issues in the boat fuel system or the motor fuel pumps will seldom show in recorded EMM data, just the nature of the beasts.  Added sensors cost money, increasing motor cost.  Look at the price increase of the G2 motors with VST fuel level and exhaust temperature monitoring.
Your tank and fuel line substitution rules out most fuel restriction problems.  Run the lift pump and HP rail VST pump pressure tests, can still be issues with on motor fuel lines leaking air or plugged/restrictive from debris or interior rubber breakdown.

Hook up your laptop with the E. Diag. software. Enable all the parameters in the Engine Data logging section.
Run tests until you have several rpm restriction failures recorded.

Run the diagnostics injector and ignition cut out tests while the motor is displaying rpm limiting.

Since there is one failing injector that has restricted fuel flow, there are likely to be others.
Try the Rich/Lean adjustments in the software on each cylinder.  May be anything from dirt impeding injector plunger/nozzle to worn components.  With unknown high hours on the injectors, may be better ROI to replace all 6 rather than sending to states for pro. cleaning.

Any black debris particles found in the boat fuel system or the motor fuel system filters including the VST return line filter?

The VST tank contains a fuel pressure regulator valve, test in the service manual.
Also check the VST vapor vent tube, no liquid fuel should pass.  Causes extra rich running motor from raw liquid fuel dumped into the intake plenum and on into the motor.  Will limit rpms and cause rough running

We have some of the worst gasoline in the US here in Pac. NW.  High benzene and industrial ethanol salts.  Both corrosive and damaging to fuel systems.
