comment Home built in-dash Navigation system or programmable/open api after market one?
a few comments: 1. this is close to a 'shop-for-me' question, which is discouraged per the FAQ. 2. you may be better served asking on the electronics SX site.

comment Host of small performance problems in 2006 Hyundai Elantra
I feel this question is quite difficult to address in its current laundry-list form. It is exceedingly unlikely that all your symptoms have a common cause. Perhaps you could break this question into a few smaller questions (reduced power and rough idle; vibration at speed; clunk during low-speed turns; clunk when shifting from park; electrical issues)

comment Host of small performance problems in 2006 Hyundai Elantra
re: letting the car idle to reach operating temperature before driving away, this is actually recommended AGAINST by my recent VW and AUDI owners manuals. They say 'start up and drive away'. A car will take a long time to reach operating temperature when idling with no load, all the while burning fuel and polluting the atmosphere (the warm-up period has highest fuel consumption and emissions). That said, I always drive gently for the first 10-15 minutes.

comment Why is my motorcycle losing power when accelerating?
@AdamRobinson the key here is that the RPMs increase without the motorcycle accelerating. This is the hallmark of a slipping clutch, and could not be explained by blocked air filter or carb issues.

comment What is this loud semi-regular clicking on a 2001 Honda CR-V?
Do you know if this engine uses oil pressure to adjust valve timing and/or tension a timing chain or the like? If so, sometimes the oil inlet to the hydraulic tensioner/adjuster gets plugged, and the tension will not be as high as intended, which can cause valve noise. I'm thinking of some VW/Audi experience I have.

comment Trip computer reported MPG with engine remap or chip
The question I was driving at (and what I believe you'd need more information on the specific chip to determine) is whether the factory ECU sees the actual injector opening times, or whether the "piggyback chip" comes in downstream and asks for more fuel without the factory ECU knowing. Answer this question, and you've answered your question. I've done performance chips on two of my vehicles, (one re-flash, one solder-in), and in those cases, the chip played nice with the factory ECU such that the true, "chipped" operating state was known to the factory ECU.

Neither an air/fuel ratio sensor nor an oxygen sensor measure fuel consumption. Fuel consumption is measured at the injectors.

comment Air trapped inside radiator after adding coolant
@JuannStrauss, your answer got flagged by the auto-mod system as potentially low-quality because of its short length, hence the attention you're getting. Personally I think you've added something to the conversation, but I also feel that 'take it to a mechanic' falls a bit short.

Can you provide more application-specific information? My first thought would be that a chip shouldn't interfere with the trip computer's ability to read how long the injectors are open for--which is how the fuel consumption is typically calculated.

Any reference regarding your statement about how only Toyota engines measure the fuel volume passing through the injectors? This doesn't sound correct to me.
