tnx

I have used it several years for Porsche chips. Should also work with BMW.

I played with it a bunch, but not knowing the locations of the maps or checksums makes it pretty hard to make sense of. If anyone here has busted the M42 chip successfully, they are keeping quiet about it.

Motronic editor is not the easiest program to use or understand. I also use Winols, which is easier to use. I have used Motronic editor to compare original M42 chip to BMW Motrorsport M42 chip. There is quite a lot difference between these two chips.

Would you happen to know the locations of the various lookup tables and their checksums?

We've succesfully downloaded the data from GE-Power chip, and raised RPM's from 7000 to 7300. After burning the nice collection of 4 chips for us, all worked and are still working great in all cars. But I was no able to understand the tables and the motronic editor program theese few years ago so we've finished just copying data and chips.

Somewhere about february this year I've tried to look for any info about motronic editor and after spending few hours on it, I've finally found VEMS, which seems to be much better sollution for the engine. Finally I'm collecting money for the VEMS unit

In M42 all is made really that well, that combining own chip is trully not effective unless You have sport cams and ITB and exhaust with more flow. On the other hand If You have engine modded that way combining it with motronic chip is still restrictive because of AFR which doesn't let Your engine breath far more.

So for stock engine just use one of theese "+17 HP" units which are plenty on e-bay and for modded engine use something smart and programmable like Megasquirt or VEMS for example. /theese are the cheapest reasonable ECU's availlable - Some says that it is hard to setup idle with M42 on ITB's and megasquirt, so ask yourself if You need a car for the street /than go Link or Autronic or any stuff which makes kits exactly for this engine/ or if You need a car for the track /than go Haltech/ Or If You are the real enthusiast and You just like motronic - play with if :-)

Some Years ago the programmable ECU's were impossibly expensive, now we have http://www.vems.hu so we can mod our engines really well and it doesn't really ruine our pocket :-)

This is not only mine point of view - many other tuners have found stock ECU too restrictive to be used with highly modified engine.

No not yet. I have not played much with M42 binaries. So far mostly with Porsche 944 turbo ones.

Vems seems to be quite promising system. A friend of mine installed it to his Porsche 944 Turbo. It was not a direct bolt on job, quite a lot different kind of difficulties. Nice thing is you can use almost all exsisting Bosch devices, so you just delete Motronic and swap Vems in. I let him "rehearse" and when his is ready i will also install Vems both to my Porsche & BMW. for now my BMW will use Motorsport Motronic ECU unit. I have also good experience with different piggy packs with Motronic, like AFM LINK, Intercept LINK and Perfect Power SMT6. I suppose these can adapted to M42 Motronic easily like they did with Porsche's ECU.

Pigs! True - friend is using Audi S8 hot wire air meter combined with stock motronic and SMT6... But this is N-group engine so the cams are stock and many other things are stock... He says that the car greatly improoved it's ability to get into high revs, but it is only noticable by himself...

The truth is that he has spent 500EURO writing the sport chip for this setup, 200 Euro for S8 air meter and 150 Euro for the pig...

so, for 850 euro it is better to buy 450EURO VEMS unit and to put MAP sensor inside the pipes. You still save about 300 EURO in Your pocket and much greater controll over the engine...

But You have to play it Yourself to get the things done :-)

On the other way You have just great help from the other VEMS users, because of Open Licence...

It feels like every user of the VEMS wants Your system to work fine :-)

Try to find that kind of help with the SMT6... Good luck!

Vems is great system, but i have to disagree of some things. Vems is not a plug in system for every car. It might be easy to install for example to Audis because Vems developers have Audis, so they have tested it quite a lot. My friends Porsche set up has been quite challenging to set up, not much help, beacuse not so many Porsche 944 Turbo Vems installations around. I only know one which is running and that car does not use original Porsche/Bosch reference sensors which get their signal from flywheel. My friend use original sensors and that route has been challencing. He made engine wiring harness totally new, also quite a lot extra job on that. When you change to Vems or Megasquirt you must be ready to have another "hobby". Thats what these systems are. For most of us piggy back systems with original Motronic are much more sensible to have. I know one Porsche 944 Turbo here in Finland which uses SMT6 with VW Pierburg MAF. This MAF cost about 40€ from a local car parts store. Custom made chip cost 50€. This system produce 285hp which is 65 more than original setup has.
500€ for custom chip is way too much. I can have a custom made chip for 150€, which include all necessary dyno time. Also S8 air meter can be bought much lesser price.
I am not against of Vems. Most likely i will install it to both my cars (Porsche & BMW).

what will happen to me if I say all addresses of maps of M42 chip? ....

i need only bmw # number and sw number of the ECU...

True, true ;-)

The info about prices was taken from the guy who owns this S8 combined E30... So I trully believe that it may be much cheaper...

I agree, that piggy is better for most people, but I meant, that if You are going for serious powergains, it is doubtly to achieve with pigs and motronic :-)

VEMS people do own audis, right, but there was really much done to make this system easy to add to any engine. But first , You have to know what is every wire there for...

I'm the real M42 enthusiast, but I see that stock motronic doesn't leave me too much place for my custom changes to the engine. And as I'm thinking about turboing it - the first step to start with the engine schould be ECU.

But this is not really connected to the topic of the thread... I will search once more for motronic editor stuff :-)

I wonder why there are not so many possibilities to improve your BMW Motronic like there is for Porsche Motronic. For example there are lots of different kind of systems available for 944 Turbo's. You can tune your Motronic in real time.
I disagree with you what comes to ECU's. There are possibilities to have some real serious horpower with stock Motronic without problems. Here in Finland is one 993 bodied Porsche 911, which have over 600 hp with stock motronic unit. It only have a custom made chip. It run just great and A/F ratio is also optical. It just required some dyno time and a tuner who knows his stuff. Standalone system would not give you in this case almost nothing extra to improve system.
I got a special chip for 944 Turbo. It was made by a german guy (a retired Bosch engineer) who was responsible of Porsche & BMW Motronic software in the '80/90's. His said Porsche detuned Porsche 944 Turbo's software to lower ratings, because otherwise it would have been too fast for 911 Turbos, which had that time Bosch K-Jetronic systems. He wrote a chip which he said would have been the one he would like to installed in the first place. Motronic still offers you great possibilities, you just need to know what you are doing.

For example Max tune lets you to tune your Motronic quite nicely. Also some nice stuff can be bought from Lindsey Racing and Vitesse Racing

The M42 ECU # is 175. I don't remember the full number.
