Home built in dash live engine monitor

[Dessertrunner]

I was thinking given some of my problems with my engine such as high idle, surging at 2,000 to 3,000 and irricate fuel economy that I might build a in dash engine monitior that would look at a couple of critial engine funstions as well as trends. Things I would monitor O2 sensors, engine temp, air bypass etc. I am sure that my problem is one bank fighting with the other in terms of info so the car is trying to decide which O2 sensor is giving correct detail.
The job could be done using a PLC and feeding to a touch screen that would supply the info and the data could be down loaded to a laptop when required. I have attached the link to the kind of screen whit examples displays that can be had remember that it operates with what is call Pages and they can be stepped through.
What do you all think.

Tony,
Excellent idea. Cobb makes something similar that works in all other Subarus (I think) -- they call it their "ACCESSPORT", I believe.
Why not just use the Subaru Select Monitor as a starting point?

Tony you ought to contact SVXtacy, who had an interesting monitor system built into his turbo car.

In fact, he is selling or has sold the car now. Check out his install at

Click the Electronics link.

He would give you good information if you sent him a PM.

Sounds to me like shooting quail with missles.

It also sounds like you have an unmetered air leak.

Beav.

So. Kain tuck has some really large quail, that give off a fair amount of heat as they fly?

All the jokes and rumours about everything being way bigger in America, they are true, then?

I plugged the car into the subaru test unit today and looked at all the test info I think a air leak mite be the problem the O2 sensors behaved differently with one reading .02 and the other .7 when the car was crusing the numbers reveresed. I need to check them on my other SVX as they were jumping all over the place and would have thought they should have been more even and more consisdent.

Beav since posting the last reply I took your advise and went and had a look again for air leaks this was about the 6 th time. I used a mirror and a torch to get under the intake manifold and guess what I found the hose off the induction solenoid value. Put it on then took the car for a drive and it seems to have fixed the problem. It is night time here so I have left the battery terminals off over night so the computer can relearn tomorrow. Thanks for the suggestion it seems in spite of the number of times you look it is always the sysptoms that should be followed.

Despite Beav pouring cold water on this idea , I have looked at it a number of times for the SVX. There is no transmission oil temp gauge, or any temp gauge other than water. And nowhere to fit a boost gauge, if compressed air is yore thang

Because there is nowhere to put gauges that will not look like the car has been ricered, if I may coin a phrase, behind the stereo cover would be a good spot for a single din monitor screen.

This would have the benefit that you could vary the information/virtual gauge for whatever you were checking, oil temp, o2 mix, whatever. Plus it would be neat and unobtrusive.

I'd like to see anybody come up with suggestions that would fit in a single din slot.

Joe I have a SC kit so I have needs to know what is happening with the engine that is why I thought the plan was a good one. Also I need the practice with programing. Not sure if we can get a touch display that will fit in the Din slot but I will check.

Yes, sounds good Tony. You have the same requirement. I am supercharging.

As I want the car to look as stock as possible, I would not be all that happy with big 8" screens sitting on the dash. It's true you need the info as near line of sight as possible for safety reasons, but I'm old fashioned. I will want the interior to look stock when all the tuning is finished, and all that is left to be done is driving and smiling.

Let me know if you find anything reasonable. I'll send you anything I see as having merit.

Joe

[svxistentialist]

Are you using lan's kit?

What SC kit do you mean? How many lbs boost are you using? Are you changing compression?

Joe

[Dessertrunner]

Yes I have Lan's kit as yet I have not installed it.
Tony

[svxistentialist]

Excellent.

Nice piece of kit. That Whipple blower is a good piece of equipment. It should transform the car for you.

The first over-the-top blower Down Under!!

Here's a possible solution:

Edit: may only be for OBD2

[svxistentialist]

Thanks David.

That is EXACTLY the device I had in mind.

I sent them a query to ask if it works with OBD-1 cars, or if it can be made to work with them.

Thanks for the link.
