My MPGuino is off a little bit... compared to my tank calculations. Only got 55.5 mpg instead of the 58mpg on the MPGuino. I'll have to adjust the numbers in the MPGuino. I seen a thread here showing how to adjust it.

I think an alternator delete compensated for by a solar panels is an awesome idea
Don't forget to add more battery capacity

Yep... I'm going to do some testing with my current battery once I fill up with gas again in a few weeks... I only drive 6 miles to work one way, so i really doubt the short round-trip will dip it all that much. Especially now that I don't need to use headlights and warmer weather. I'm going to order LED headlights soon... I think I'll just run without the alternator and charge the battery up at the house at night. I'll keep my alternator on and keep the belt and tools in my spare tire area in case I need to put it back on if I get in a pinch.
I'll likely switch to a larger marine battery soon.

Hopefully your '92 is new enough that it isn't sensitive to voltage dips. I know my experiences with earlier OBD1 showed they didn't appreciate it. Ran poor and hurt mileage.

If you haven't already, clean your grounds and major electrical connections so you don't lose more voltage there. And maybe consider boosting voltage going to the ECU.

I cleaned and installed new ground wires including the ecu wire to the thermostat housing. Before I go investing in the solar panel and controller, I'm going to see how much effect running only the car has on dropping the battery voltage and how far I can drop be before it affects performance.

Well... getting into warmer weather with Spring in Omaha, Nebraska... temps have been between 40 and 75 degrees throughout most days, but a cool front will drop us into the 60's.

The warm air intake mod I did keeps improving my mileage...even with the warmer weather. I may break 600 miles on this tank... 10 gallon tank.. I know I'll get close... then I'll be in the 60 mpg club

I suspect it'll only get better as we get into Summer soon.

My kids are now starting to ask me if I can put a WAI on their Hondas

Need to get onto my other mods soon!

Is there alternative other than a marine battery that you would consider to try? What about a lithium battery?

Sounds very expensive. I wonder what type of cost that would have...

I'm not so up-to-date when it comes to batteries cost, and it's probably way cheaper there in the U.S.A. than here in Brazil, but since you would be able to avoid an oversized battery in order to get the higher capacity you're looking for it still sounds advantageous. The overall weight savings considering the whole vehicle might sound negligible at first, but that would still be an improvement.
