O2 Sensor (For Carb tuning)
I am looking at programing a pic to collect all the engine data I need and pump it out to a serial port.
Software would then display this as a digital dash display.
I am starting next week and hope to have the pic code done over a 1 / 2 week period. (software might take about same for an alpha)
I hope the software will embed in a standard frontend, and I like FP
(FP embedding thread)
IF I can measure 10 items, what would be best ? the top ten of choosen data retrival????
2) Tach (Revs/RPM)
3) Engine water temp
4) engine oil temp
5) Oil pressure (could be diffcult)
6) Turbo boost (as above but a bit easier)
7) Inter cooler temp

Forgot you def need a fuel guage.
OMG! i've been looking all over for how to do this!! thank god someone with more skill then me is doing something! lol
what about getting it display on an LCD display either thru hardware or and LCD screen thats plugged into the computer, i don't mean VGA lcd but also something like a matrix orbital screen. this way if someone is watching a movie or whatever you can still see the car stats!
is it possible to have like a fuel gauge/meter? telling you how much fuel you've got left, etc.
what about an ODO meter to tell you how far you've traveled.
i've had this idea to do a custom instrument cluster to replace the original with an all digital display thingie.
also make it skinnable! if it works great i'd actually pay for it! =D
I cant believe I forgot the fuel gauge................
I hope to start looking into this from monday, at the moment I have a problem, I was re-painting my (pc)car, started last year! (and I aint drove it in 18+months)
The current vehicle is showing its age (its 20yrs old)and when I lost the engine in my taxi I lost the job also.
So I have one crap vehicle, one half dismantled at a lock up, and a growing parking bill for the lock up.
So I have to move it back home to my drive ASAP in its half finished state and avoid the lockup owner as I am behind on the rent.....
once I get this done (tomorro) I can relax and not answer the phone.....
(I will pay him, but no job = no cash for the moment so I can pay him weekly but cant afford the bill getting any bigger as i pay him)
((and car at home = faster progress and testing))
Got a bit of a problem finding pressure sensors in the uk, uk's most common supplier maplin, dont list them anymore.
saw these and had a thought....
And I have seen them as low as 3.99 so not going to break the bank as only about 3 are needed.
going to get one and see whats on the inside, hope its a seperate sensor with an analog output
I'm working on somthing similar. I'm planning on measuring things that the scantool doesn't do fast enough for my needs or are unavailable. Like speedo/tach and unavailable inputs (including switches, dummy lights etc). I'm refactoring the circuit board that the gauges use and I'm going to tap those signals. They're all nice 5v signals coming out of one of the ecus.
The other thing I'll hopefully get to is to use the abs wheel speed sensors for differential tire pressure monitoring. It would be a nice thing to have.
ECU's - Dont have any in my car!Originally Posted by shotgunefx
Differential wheel speed wont work, unless you have a cray, as tyre ware will give much more difference than pressure, and what about cornering?
I would love to have tyre pressure, but cant think of anyway to do it except rf.
