Intereting digital gauges, lap timer & acceleration project

[318ti]

Hi all,

I read an interesting thread at the Subaru STI forum I just had to share with all of you. Jason (aka STI Robot) used an Arduino microprocessor to monitor standard temp and treasure gauges in the engine. (Oil preasure & temp, turbo boost, etc...), included with a 9 hour lap timer and a acceleration gauge. All using off the shelf parts and sensors. Easy to configure and expand.

It would be easy to add Outside and inside temperature sensors, Cylinder head temperature sensors, volt and Amp meters - really limit less.

The display is simple and cheap LCD character display.

Have a read at - Link

Jason has a proto type video clip at -

parts can be had from

Sensors can be found at -

(I have no attachment to these vendors -it is only a pointer for your convenience)

Let me know what you think

im gonna invesTigate, looks like a mod worth doing

lol - I thought so to. I ordered the parts already

Good luck finding a way to get oil pressure on an m42 or m44... I've not seen a way to tap into the oil supply system without impacting overall oil flow. There are custom oil filter mounts for the m5x motors, but not ours.

You can easily get oil temp of the oil in the pan by using a oil drain plug with a temp sensor in it, but you should really measure the oil temp in the engine, not the pan.

There was a write in the forum on installing VDO Gauges. No one said it was easy mount a pressure sender - but its doable.

I would welcome your comments if you think I am headed down a path less traveled.

Thanks

I guess I should clarify. I've not seen a clean, well working, non-leaking way to do it on the cheap... I'm sure it can be done, it will just be a pain...

The best write-ups say you should use the UUC oilcenter instead of an oil distribution block. Like I was saying, I don't even know if you can find an ODB for our cars. The oil center costs 100$. There is a writeup from a user "Mr.M" on Bfc where he did this on his 318 using the UUC oilcenter.

It can be done, but I don't think it can be done correctly just buying a VDO sensor/gauge and running some wire. A lot of people try to do it on the cheap, and not pay for a good oil block to tap the sensor into.

Great information. Thank You. I will look into this before I start.
There is always something isn't there

Many Thanks

Does anyone know if the Oil Filter housing from an M42 fits on a M44?
Can't find any references to it

[Update] - Looks like it willl fit. Part No.'s for the gaskets are the same as are the bolts. Filter is different.

Thanks
Peter

I would imagine that it would fit. The reason I say that is because my M42 has an M44 oil filter housing on it. So if the m44 fits on an m42, I would think you can go back the other way.

Hey, cool stuff. Thanks for linking me and all.

If any of you actually make something similar to what I did could you post it up on the original forum post at iwsti. That way it can be a one-stop-shop for people wanting info on this.

I think you forgot to post this part up (link to the original thread):
