I think this has escalated waaay out of the context it was originally in .
My first impression before even opening this thread , was that this was a datalogger for parameters used or produced by the engine or computer.
Stuff like throttle position , fuel injector pulse width , accurate miles per gallon .... not shock travel , shock tower deflection , or frame twist.
It seems like this has escalated to something the original poster didnt want it to , and now hes streched thin trying to appease the masses.
I could be wrong tho
Yeah, you are prettymuch right on. I am doing this as a sort of after-work fun project. Maybe someday I would try to sell logging units (more generalized ones for MANY models of cars), but for now it is an enthusiast project.
Yes, accuracy is not cheap or easy. It takes copious amounts of time to get good sensor calibration curves, and $ to get good components. Then not half-assing the MCU coding takes even more time. I have a little time while I am on my engineering internship (well, a few hours after work anyway). I just want to play around with making my own, NICE, data acquisition system.
And yes, originally it was going to be an engine-parameter only setup, that could be used to understand how the engine was tuned from the factory, or by whoever's chip you have in there. Then from there one could perhaps decide to further fine-tune their motor. For me, this is an intermediate step of sorts...once I get a fully working DAQ system going, I plan to make a stand-alone ECU. Rag all you want, I am WELL WELL WELL aware of what cost effective, widely supported/used units are out there. I built a Megasquirt & used it on the last car, and have lots of respect for the TEC-3 unit. However, I will not start my own business someday selling Megasquirts, I will need my own products. Hell, even if it is a side-job, I will at least enjoy what I do, and that is what counts to me. I just happen to be a part of the BMW enthusiast community, and am a little perturbed that there are not enough cool goodies for the M42. Poo on the M20.
As far as wheel speeds, that is fine. It is just interfacing 4 more VR sensors, and they do not even have to deal with counting missing teeth like the crank damper wheel does. Shock travel & GPS...hmmm, yeah definitely not gonna lose any sleep over figuring those out. Perhaps someday, but I feel that engine parameters and wheel speed are a LOT more useful. There are not that many people out there with coil over suspension (even the ones that DO have it, cmon I know you are not gonna go adjusting the springs every week based upon datalogger readings). And GPS, well, useful or not, go buy a TomTom or something. Not that many people track their cars, or care enough to get anything meaningful from the GPS reading. Lap times are more than sufficient for the enthusiast.
Haha, and no I am not ragging on anyone here. I just like to be to the point, and I AM The Godfatherer...I can voice my opinion freely. Don't like it? I'll have ya whacked by my coisin Little Tito.
