People with MPGUINO

Sounds good, I think I may order one. Thanks for the reply everybody, I got the answer that I was just looking for.

Is there anything of the nature for a carbbed car ('88 festiva)

[theholycow]

With a carburetor, AFAIK there's no decent way to measure fuel usage. A vacuum gauge might give you some useful information; you could either try to keep vacuum high, which means that you're driving slow, or you could try to keep it low which means that you're not wasting fuel pulling a vacuum.

In my experience the Festiva is a car that gets about the same milage no matter how it's driven

[odiekokee]

I can attest to that. I get 39-40 regardless...and that's with a huge crankcase blowby and leaky oil. worst i've gotten was 36. I've got a vac gage, usually pulling 3-5 (not sure if that's in or mm of mercury) at 75mph. not quite WOT but near it.

Alright, I'm looking at one of these as an option for my '90 Laser 1.8L but on their wiki page they do not list the parameters you set for accuracy for any DSM except the 1990 Mitsubishi Eclipse 2.0L Turbo model.

What type of hurdle does this present? Would it be a guessing game to dial it in?

I thought I read somewhere that it would show when my VX was in lean burn mode.
Maybe those with a VX could pipe in?

Not a big hurdle as usually you have to fine tune it anyway. Basically you would just start with either something generic or just use the 2.0 Turbo numbers and calibrate it over a few tanks (which is SUPER easy, first tank/calibration should get you pretty close).

Here is the directions you would use to calibrate it and dial in the accuracy in case you missed it: MPGuino Calibration

As for the VX lean burn... I do not think it shows this specifically, I think you could probably just watch the Gallons/Hour number and when it drops (under same throttle position), you hit lean burn.

So it's like dialing in the ScanGaugeII? Just adjust what it estimates your fuel useage is after the first few fillups?

Seems like a cheap price for such a product. Granted, it's not a SGII but its close.

[ben98gs]

I have not used a ScanGaugeII, but if that is the way it works, then yes, the MPGuino is very similar.

You are right, that it is not a ScanGauge, but the MAIN point of the MPGuino is that non-OBDII cars can use it. You cannot use a ScanGauge with my car, and thus I built my own MPGuino instead.
