lax01 Posted March 14, 2005 Report Share Posted March 14, 2005 2nd the pinI'm currently talking to a few contacts to find out some useful information...does anyone have any contacts in the Hondata program or anyone associated with it? Maybe we could use their help in the development phase....Anyways, this is exciting... Link to comment Share on other sites More sharing options...
Slater Posted March 14, 2005 Author Report Share Posted March 14, 2005 i did quite a bit of logic circuit stuff, all fairly simple though. i'm not sure about the other stuff though.we did some assembly language programming too, but i imagine i'm rusty at that as well. i dunno if that is even usefull?Heck yeah it's useful. At this pont we can't be picky about who helps. If you are willing you are welcome to contribute. We'll take whatever we can get.Thanks!- Slater Link to comment Share on other sites More sharing options...

Maybe we could use their help in the development phase....Anyways, this is exciting...←You won't get any help from Hondata, as they completely wrote their own code from scratch that just happens to run on the Honda ECU hardware. They have also gone to great lengths to protect it (as you can imagine) because it's literally worth millions. That's like asking Coke if they'll help you figure out hos to make your own cola. No dice.Where you CAN go for info and help is http://forum.pgmfi.org/. They are all there just like us to help and help us learn. Many smart people on there, as well as a ton of information that is directly applicable to our ECUs.Also, do a search for Motrinic and Jetronic programming and hacking. There is quite a bit of info out already for the older Motronic hardware that can still be very useful for us.Finally, please sign up for the Alfa75 Yahoo Group. They have been modding these ECUs for years (Motronic 3 and I believe the early 4s i.e. 4.1). There's one guy on there in particular that is a GURU of microcontroller programming and Motronic hacking. He's in anotehr country like the Netherlands or somewhere like that. He would be the guy that would be able to really help us out.- Slater Link to comment Share on other sites More sharing options...

Guest DougK Posted March 14, 2005 Report Share Posted March 14, 2005 Pinned.I will father your babies if you figure this out.Good luck! Make software to tune timing and AFR on the fly and this will be awsome. Link to comment Share on other sites More sharing options...

JHEIII874T5M Posted March 14, 2005 Report Share Posted March 14, 2005 not to totally destroy everything, but for $1000... the Civinco programmer can be had, which has the power to tune on the fly as doug mentioned previously.either way, best of luck man!

That's what an EEPROM costs. Plus you would learn a lot in the process.Hondata with boost support, datalogging, and a programmer is $1295. Uberdata, the open source competitor to Hondata is free for the software which does boost and datalogging, $5 for an EEPROM chip, and $75 for a chip propgrammer. So $80 vs $1295 for the same thing.I don't know about you, but I don't have a money tree growing in my back yard.- Slater Link to comment Share on other sites More sharing options...
lax01 Posted March 14, 2005 Report Share Posted March 14, 2005 nope, a lot of us don't...the open-source platform of this concept could be truly revolutionary in terms of Volvo modding (as it was for the Honda community)...I really hope we suceed in this...

It could completely revolutionize the performance modding community. At the same time however, none of the major suppliers of ECU upgrades will be at risk since there are people who will not be willing to use the open source solution due to fear/loyalty/etc..

jroot Posted March 14, 2005 Report Share Posted March 14, 2005 Well..I may be able to help, not sure how much time you are looking for.Might have more time come summer, plus I'll probably be working with some very very intelligent people when it comes to this stuff, so I could ask questions easily.Anyhow I have experience in assembly language, c++ .net, few other things not related..then also:in my current comp arch course I am building a computer using circuit chips and such..then by the end I will have a running computer and will run a few instructions on it..but this is a pretty basic computer Link to comment Share on other sites More sharing options...

At the same time however, none of the major suppliers of ECU upgrades will be at risk since there are people who will not be willing to use the open source solution due to fear/loyalty/etc..←Exactly! Hondata still sells a boatload of systems. Some people feel you have to buy the "name brand" goods and pay a premium for it to be worth a crap. That's why we bought Volvos instead of Yugos. That's why I would buy a Pioneer head unit instead of a Kraco. That's why I buy Charmin TP instead the generic stuff that you can still read newpaper articles on...However, with the premium price of Hondata comes service, warranty, upgrades, dealer network, etc. With open source you get what you get. And if you don't feel comfortable soldering on your own ECU, or even know how the heck to modify a 3D fuel table, or what is the best value to plug into an ignition table, it's worth it for you to buy a premade canned chip where you just send of your ECU and get it back ready to plug and play. And that's fine. Of course the chip isn't optomized for your car or your mods, but it's better than nothing.No, the DYI ECU modding is for the hardcore guys that WANT the power to be able to tweak everything in their ECUs to the nth degree. The ones that are willing to spend dozens of hours on the dyno because they think they can tune it better than TME or BSR who also spend dozens if not hundreds of hours on the dyno. And of course TME and BSR thought THEY could do it better than Volvo, which spent thousands of hours on the dyno!We'll see what happens. Just keep in mind we all have families and jobs and won't be getting paid for this. It's not like we're going to have a fully functional tune on the fly system this time next week. Uberdata took THREE YEARS to get to the point where it is now. But boy was it worth the wait. For the first 3 years there were very little mods available, and they were limited and crude. But it was free. If we are able to cook something up for the Volvo and it's free you can't be bitching because it's not done soon enough or good enough or whatever. If you are sick of waiting or don't like the end product, buy one of the commercial options. Also, if you blow up your car or burn up your ECU it's not our fault. Just because there's instructions on the Net about how to build a bomb doesn't mean everyone should do it. Know what I mean?- Slater Link to comment Share on other sites More sharing options...
550 Posted March 14, 2005 Report Share Posted March 14, 2005 Programming is my game... sadly IM a geek. I have some soldering exp... but I wouldn't even want to do it. IC's SUCK hard styles. Just let me know what you need programming wise, and other things as well minus the soldering... Link to comment Share on other sites More sharing options...
lax01 Posted March 14, 2005 Report Share Posted March 14, 2005 Very well put...I fear many will jump off this project once we don't get immeditate results....but fear not, this is a process (not that I have any idea what its going to take to actually accomplish our goals) and as Slater says, its going to take some time....I'm in for the long haul cuz I truly want to understand how my car is managed....I'm the first to admit that I've got a lot to learn, but am ready to do all that I can to help Link to comment Share on other sites More sharing options...

I am certainly no guru - I did some hex editing to do basic hacks, USED Uberdata and tuned my car with it, followed basic instructions on how to mod my Honda ECU and use it correctly, have some basic electronic skills, basic programming skills, basic encryption skills, am a pretty good solderer, and know a fair amount about cars and tuning. But I certainly couldn't single handedly create something like Hondata. At least not without a Sally Struthers Correspondence School TV/VCR Repair or Dental Technician Degree.- Slater Link to comment Share on other sites More sharing options...
