gauges for motorhome engine

[BARNES]

I have a 96, Ford 460 class C, motorhome.

I would like to add some gauges to monitor the engine. The 460 is fuel injected and I would like to add a tach and a vacuum gauge.

Back on my older carburated 454 chevy I used the vacuum gauge to help get better miliage by driving with the highest vacuum reading This took throttle control but it did help.

Since this is a fuel injected system with vacuum management would I get the same results?

For the tach can I tap off the distributor or do I need to go into the ECU?

Thanks in advance for your help.

check out a scangauge. dozens of gauge options, 4 at a time. trip meters. fault code read and reset. works great, and will work on any OBDII vehicle.

I second the scanguage suggestion. It's small, and can be mounted without cutting holes, or mounting several individual guages. One of the good things is that it reads transmission temperature.

If you choose, u can add a conventional tach and vacuum gauge.

Any standard tach will work if it has a conventional distributor. If it is coil on plug, just watch what u buy, mos new aftermarket tach are compatible.

You can use a conventional vacuum gauge, tee into any port downstream of the throttle body.

Thanks for the info on the Scangauge. I was going to mount the gages on a window post mount but this looks like a cheaper way to go.

Do a search for Ultra-gauge...it is cheaper. Need to check and see of your MH is OBDII compliant.

Yes you would.

You can tap just off the Ignition Coil for the Tachomter.

By the way a scanguage will not work on your OBD-1 system.

I use a Actron CP9190 and it tells you a lot on the OBD-1 system
Here is an example of its output:

Yeah you just told me on another thread that it was a OBD-1 system and not OBD-2.

I guess I will go the the mechanical gauges.....
