I'll post a pic up of my rpm/mph. I'll double check to make sure its the stock transmission. It was previously owned by just one person which was an older gentleman. I'm looking to purchase either Scangauge 2 or Ultragauge. Any recommendations?!?! Pros vs cons

I have the UG. It was much cheaper. It had more data available on each screen. And I think it looks better in our cars (the rounded corners of the black plastic housing fit the OEM dashboard design better than the ScanGauge color and form).

EDIT: btw, if you have the stock wheel/tire sizes your HX will likely show 2300 RPM at 60mph in 5th gear. My old DX trans showed maby 2450rpm, and my 93 CX/VX trans about 2050rpm at 60mph.

Stock tire size is a good thing to check. If you have oversized tires, you'll have under-reported mileage because you'll be traveling farther than the odometer reads.

Only reason not to clean the EGR is if you don't think you'll be able to put it back together correctly.

Your short trips certainly aren't helping, but you should be able to get at least in the 30s in all but the worst conditions.

Cool. I was spot-on. 2300. Fwiw, I compiled a set of transmission specs including OEM tire sizes here:

Hey everybody! My ultragauge just came into today and I finally got around to using it after work. I'm pretty excited! After driving around for 15-30 min the gauge was telling me that I am getting 42.1 mpg. A quarter of it was in the small roads. I haven't calibrated it yet because I'm not sure how to go about it. So, does anyone have any suggestions?

See what the gauge reads for a whole tank then refill and see what it really takes, then adjust the gauge until they both read the same.

The Ultragauge will never be accurate if you engage lean burn. http://ecomodder.com/forum/showthrea...how-24948.html

With lean burn I should be getting better gas mileage then? I know these cars are made for the lean burn but will consistently getting into this mode be bad for the catalytic converter?
