Alright, so I got an HX ('96, so OBDII) and I want to get instrumentation, but not sure which way to go. So first, is the following correct?

If I get a scangauge II it will screw up the readings whenever I go into lean burn, but I can program it to tell me when it enters lean burn.

Ultragauge will also be thrown off by lean burn and can't show it via custom gauge but can at least tell by watching when the rear 02 sensor goes to zero volts. Also cheaper.

MPGuino will give accurate readings but is harder to install and can't clear codes. Cheapest.
----------------------------

I am not opposed to a little digging/learning; haven't done any soldering but have tools/help at my disposal. Need ability to clear codes unless I do an exhaust swap.

Given that, what option sounds best? I'm thinking either [Ultragauge + possibly a home rigged lean burn indicator] or [MPGuino + definite home rigged lean burn indicator and either exhaust swap or OBDII scanner*]


*thought these could be had cheaper, but essentially cost as much as an ultragauge so at that point I might as well get an ultraguage too, which would be kind of silly
