Open Source maps - MY00 Turbo 2000??
Are the ECU's for the MY00 Turbo 2000 Open Source mappable yet?
If so does anyone know anyone good who is mapping using Open Source? :thumb: |

After my mates latest experience I wouldnt go near a open source mapper now,
When it doesn`t go right you have very little come back, where with Ecutek they have backup, Ive seen a car mapped by a OS mapper and once he has taken the cash he hasnt been near or he is too busy with other customers so id stay well away, There are threads on it on here and I think you will find that the known ecutek mappers get better results, Ive seen wrx`s with more torque then he could get out of a sti lol shows you just how good they really are when you get the car on the rollers to check and not just the road and trust me when I tell you its runnin xx bhp bull. Your paying your money and I wouldnt go down the OS mapper route ever again after what I have seen. |
Does anyone know what software people are using for open mapping of those year ECU's? I bought a Tactrix cable years ago wanting to have a look in my ECU and tweak things, but the open source software around wasn't able to do the JECS ECU.

I have next to no knowledge of what the OS community are doing on the 99-00's but it was said on here t'other week that the process stood a good chance of bricking the ECU. If that is the case, I can only suggest that either the software is wrong, or the methodology is, as there's no good reason why the process shouldn't be 99.9% reliable. The reprogram code in the ECU itself is almost entirely fault-tolerant. Also as Stig says, some of the OS people are top banana, some, from what I've seen, are doing nothing more than you could do yourself by downloading all the obvious tools off the web, and charging for it. It's the experience, knowledge and backup in the case of a problem that counts, and calling yourself "a mapper" doesn't mean you are. |

so are mocom racing the only people able to remap a my00 ecu with out having to ecutek it or similar? |
If I can do it (and it isn't particularly difficult to work out), there's no reason why others shouldn't be able to get it right.
However, the last time I did take a looksee what the OS lot were talking about re. the JECS ECUs, someone thought they'd worked out (or copied from somewhere else) the communications baud rate used in flash mode - but the figure quoted was wrong. Wrong only by a few percent, and probably close enough to "work", but wrong nevertheless. If that mistake has been accepted without correction, it won't the reliability of the process any favours, which might explain the "bricking the ECU" comment noted earlier. The one benefit of the EcuTeK setup is that it is a developed, long proven system rather than what is effectively a constantly evolving prototype. |
So where would be a good place to start? Who manufactures the M32? Surely there is a data sheet/user manual around for it?
Edit: think I've found one: Here. |

That's the correct datasheet, yep. You'll need one on M32 ASM and a disassembler if you're going to do anything useful with the ROM.

TBH while I think it'd be a good thing all round if EcuTeK had some genuine competition, I tend to be of the opinion that releasing this information into the public domain has more potential to do harm than than good in many cases. You only have to look at some of the people who are buying older cars now and ask how long it'd take for someone trying to save a few quid to knacker their car good and proper. I'd much rather see people go to someone like Bob, Pat or Simon, shell out some money and drive away happy than start mucking around themselves and then be here a few minutes later moaning about their bust ECU or engine, or indeed moaning at whoever it was they downloaded their editing/flashing program from - which is a large part of the reason why I haven't let anyone else have mine. That particular genie is better off being kept in the bottle IMO. If someone else wants to let it out, that's their decision. If you are prepared to put the effort in, it's worth sticking with as these JECS ECUs are surprisingly powerful with a lot of functionality already built in that isn't exploited as standard (and, indeed, to the best of my admittedly dated knowledge, not entirely by EcuTeK either). If you have the knowledge and facility to edit the firmware itself you can go even further. Although my ECU already has an Ecutek remap so is locked as I understand it? Which I'm not fully sure how it can be? Re that other file you found, yes, that'll do. Now you need an M32 disassembler, and it'd help a lot to have an oscilloscope (or frequency counter). If you already have a good understanding of analog and digital electronics, the general principles of what the ECU is trying to do, and the function of the various sensors, solenoids, relays and other devices connected to it, that will speed things up more than a bit. |

If so does anyone know anyone good who is mapping using Open Source? bricking the ECU In fairness here is what he said in total : I have next to no knowledge of what the OS community are doing on the 99-00's but it was said on here t'other week that the process stood a good chance of bricking the ECU. If that is the case, I can only suggest that either the software is wrong, or the methodology is Anyone advising you to do this on an M/Y 99-00 either does not know what they are talking about, has scant knowledge or does not mind giving duff and potentially expensive advice. As Splitpin said, speak to Bob Rawle or Pat Herbron who I am sure will give you unbiased factual information from a position of knowledge far greater than mine. |
erm. Following some research I am not even sure the 99-00 can be open sourced full stop which may be just as well.
Go for an ECUTEK if you want to retain the MAF Sensor but on these cars that is the Achilles Heel. |
isn;t the open source mapping software ripped off ecutek stuff form america?
|
Mine ain't, but nobody else has that. Feck nose what the rest are claiming to use.
Funny thing was that, as mentioned above, the last time I did look around to see what they were doing, they seemed to have a load of information wrong. So, if they've copied something else, they seem to have copied it incorrectly. There's an irony there somewhere. |
Found a suitable disassembler, but its not that cheap and I don't fancy shelling out for it (ID Pro Advanced). Some googling however shows that I may be able to do it in Linux using Binutils so I need to get doing some reading. I'm an electrical engineer so have access to scopes, EEPROM programmer etc... and I'm used to programming PLC's and HMI's, but never looked at microprocessors before until now.
