Radical idea for 'OPEN ECU' project ?

[AnLe]

you have not familiar for the gems device? And for defense of aftermarket ecu's the "safety maps" are called correction maps, or egual, there is no need to have huge 3d safety map for limping home, if some tempereature is too high -> add x% fuel, if some cyl is hotter then other, you can add 2% correction to it so you can get even engine, not the way that motronic, waits untill something goes wrong and then correct the problem (well, you got your forehead agaist windshield limpmode.

well I didnt meen to have every car included, just aby/aan, and for 3b dudes, make a conversion to directfire.

It is actually very simple peace of electronics, replacing eeprom to eeeprom aka flash and have com port to the flash programmin pins.

Rest is software, and thats is easy, ready made software is available and this kind of simple programmin should be weekends job for wizards like mihnea.

And if the big secrets, map locations and correspondigs are not to be make public, there is several methods of scrambling the data and use matching base for the eeprom.

Any one making this happen, it is Very good money, in our little country of Finland, I believe there would be ta least 10 people in the instant to pay 1000e for self programmable motronic, more than that has gone for aftermarket ecu all ready. imagine the market for uk, germany and active US community. And for knock sensing and safety maps, they would all be there.

Just found this too...

Like this?

Almost too good to be true - especially if it works - available inthe UK for £150

The scoobie folk have had group buys on these already !

[Jamo]

Have you looked at Emerald ecu's?

[S2 Ant]

Emerald have been getting used in Dubs for ages now, they are the commonly used one when transplanting in the 20vT lumps in to Golf's etc

Normal Megasquirt is rather 'basic' efi system, very simpple and easy to tune for beginner. If you want more extras, you should put Megasquir Extra sofware inside ECU. There is boost controll, knock sensor input, dual EGO:s, dual bank injection and direct injection (dont know sure that will it work in 5cyl engine).

The VEMS Genboard is yet more modern engine managment system, 8injector drives, 8ingition drives, WB O2...

At the moment i have Megasquirt Extra with direct injection in my 4cyl Mini. If I wuold now decide VEMS or MS, i wuold definedly pick VEMS. It cost more, but it is far more Oossom with 8ignition/injector and WB 02 support.

Antti, apart from the fact that any method of encryption is crackable (I know of someone who knows of someone who has cracked the ECUTek software that allows one to tune Scoobies and stuff, and their encryption method was very complicated, almost uncrackable), and that makes that I don't want to use any scrambling methods because they don't work, the problem is that I don't want to become rich, never leave home and watch my bank account getting bigger and bigger.

It would be a good thing to do should something arise and rendering it impossible for me to travel in order to tune cars, but really, all I'm interested in is to do my job and tune cars....

I'm sure I could become very rich by doing such a thing, especially if I implemented the same idea for ME7.1 ECUs, which would allow the americans to tune their own cars on homebrew setups and so on, but the problem is that there isn't only the maps that make it hard to tune, it's also the interaction between all the maps, and selling such a system would imply selling a complete manual with a complete function description on the Motronic ECU that the system covers. I do own such a thing, but I cannot make it publicly available, I'd get in very big trouble for doing such a thing, and without it, there's no way to say "here's the maps, now tune your way"....

IMHO there'll never be a "Motronic for dummies" or an ECUTek sort of solution for the Motronic. I personally can't betray all my sources and my friends that work for Bosch, Porsche AG and VAG and that have trusted me and helped me.


Just my 0.02,

Much more interesting open project would be gems type of integrated flash based adapter to put on ecu at the normal chip would go, and the adapter included online programmin and easy to use software.

Even simpler project would be software like winols but made for dummies, to look like any aftermarket ecu software, just dial in wanted adwance and fuel and of you go.

I have suggested this two times to our lord of the software mihnea, to sell this kind of softare and use some kind of copy protection (found several on the net) base for the chip, there would be huge market for this, mere 1000e / car and never leave home, just watch bank account fattening..


Of course tuning skills is needed but so is in megasqruit..

[S2central.net]

Getting back to the knock detector - here's a wee circuit that looks worthy of some time investment. The components are very cheap - I'd like to try this with and without some octane booster...

Watch this space (put don't expect results this month !)

Does anyone use VEms?? I have seen they have a nice feature for connecting an LCD and a keyboard for controlling it! Is there any Adaptor for connecting it to the S2-RS2 harness?

[elijahallens2]

Why not just go with one of 034efi's stand alone systems. They have plug and play harnesses that use your stock sensors. Since Mihnea doesn't seem to be coming to the US anytime soon, this will probably be my next step. There are many people using it on V8's and I5's and Javad is getting 599WHP with it in his 20vt so I guess it works well. http://www.034motorsport.com/product...roducts_id=364

I was just reading thorugh this and wondered why no one has mentioned 034motorsport but the last post revealed all.
I have gone with the stage IIc ecu package for my 10v. It has added features such as launch control and antilag capabilites also.
I will be offering it to other's.

[Billman]

Dont know everything about Stand alones but the Vema one has Knock control other goodies also! It is cheap and supports this Screen-keyboard feature!

[Krists]

Well, my AAN drives with Megasquirt'n'Sparks for over a year - can't see the difference between MS and Motronic. It uses batch injection& direct ignition (yes, coil on plug setup with addon board). You can't have direct injection , but You can install wideband o2 sensor, tune cruise with batch and get better fuel consumption numbers than Motronic has. Tuning for WOT doesn't do better numbers with Motronic - but I found that one has to use a bit bigger injectors for the same hp&tq numbers. EGT can be implemented for ignition,boost retard. Also many of MS users have knock sensing inputs. Let me know If You have some questions regarding MS driving S2/S4.

[Billman]

Does this Megasquirt has something like a diagnosis like the motronic! Can it check if there a problem with a sensor?
