Hi,

I've been reading the threads, and couldn't find anything specific on a ME5, mostly me7 and some me3.

Anyways, has anyone successfully tuned an me5 557P? I also have another ECU that's chipped, can I just pull that chip and re-write it?

Main thing I want to do is remove rev-limit. Misc stuff is set base timing/fuel, adjust start up enrich. Then use my piggy to tune live.

Pin 43 would only need a 12v source right?

I did find an ME5 file here, could I just modify and write that?

Here's the file:

How exactly is rev-limit removed? From what I know rev-limit is indirectly computed, not sure what parameters.

As to why rev-limit: head is somewhat built (valves and springs), need to raise rev-limit when I install cams. Current is 7300rpm, after removing rev-limit, gona use piggyback to set new limit to 8-8500rpm

Why you will use such ting as rev limiter of file you post is just there , sitting and waiting for you
Limiter start at adress 7DF0 6x5 table , factor 40

It would be better for discussionpurposes to post the file you're working on, don't you think?

Or at least give us the bosch hardware/softwarenumbers that are in the file....

There is a reasonably fully documented .ols-projectfile of M3.8.2 over here on nefmoto. Tho in german:

This can be used to adress the maps needed to be modified.

Here you have some homework-stuff

@PVL

1. I'm using Winols, is that ok? or should I use another program?
 
2. Are the files you sent, Stock Files that I can just upload to my ECU to basically reset it? (I ask because there were some differences between your files and the file I got from here, like 7DF0 was "0" and there were no labels.
 
3. How can I identify X and Y-Axis? - In most screen shots, I see labels (in German).

4. Does the ECU just use the last value if ever it goes out of MAP. (ie. if fuel map only goes to 6800rpm and inj duty at that point is 80% it will simply stay at 80% even at 8000rpm)


PS: I'm using your me3 excel file for the labels. 

" I'm using Winols, is that ok? or should I use another program?" -> Thats o.k. Most professional tuners use it also... But you are free to choose
the program you want. What suits you the best.

" Are the files you sent, Stock Files " -> Yes, they are !

" that I can just upload to my ECU to basically reset it? " -> If you have a matching ecuhardwarenumber (028x number) , then yes. (557P - M5.92)

"(I ask because there were some differences between your files and the file I got from here, like 7DF0 was "0" and there were no labels." -> POST your file please
so we can have a look !!!

"How can I identify X and Y-Axis? - In most screen shots, I see labels (in German)" screenshots added by me. Thas not too complicated, i think ?

"Does the ECU just use the last value if ever it goes out of MAP. (ie. if fuel map only goes to 6800rpm and inj duty at that point is 80% it will simply stay at 80% even at 8000rpm)" -> AFAIK yes. It uses the last known mapvalue (most ecu's do, like Digifant) So fuelling is not map-controlled after that value !!!!! (on WOT)

"(PS: I'm using your me3 excel file for the labels.  Grin)"  -> thank you   It's all made to give more insight-info when beginning with this stuff. Hope it helps !

The .OLS-file posted/referred isn't a M5.92. I referred too. Thanks to Clemens, who obviously doesn't know what he is busy with... Or drank too much schnaps.
But it doesn't matter that much. It's excellent for getting to know the structure and finding the maps.

Just the studied the maps more. The 3.8 and 5.9 looks like the addresses are in completely different locations.

Anyways, a'm I doing this correctly? I just look for the descriptors (rpm - A2 and load - A4), then figure out what the map is for?
