[12,000 RPM]

Going on record to say I should have went with 8.5s instead of 9.5s. New tires grip tenaciously front and rear though.

[CaminoRacer]

Because of rubbing, tramlining, or other?

[12,000 RPM]

Mainly the fitment issue. Having to get new studs and use spacers up front. The 255s would have had a slight bulge but they'd still be OK.

Low life is serious cuz. Did an oil change today... managed to get it on the ramps, but it was still too low Had to put it on jacks. I am seriously thinking about getting this:

It's $1,400 for the 5,000lb version I could use for wifey's car and mine. Only issue is it collapses to 3"... I would seriously have to check if I have that much clearance

[12,000 RPM]

GPS tester says the G gets to 60 in 4.8 with the AC on

Probably optimistic but definitely in the ball park. Our was starting to feel slower but I think I'm just getting used to it.  Donne more low end torque would be nice but this is enough

[Cookie Monster]

Damn, that is quick. I don't think I could get my dad's G to do under 5 seconds... maybe 6.5 seconds at best.

[Laconian]

Sounds very optimistic.

[12,000 RPM]

The app feels like someone's freshman computer science project so it's very likely. I don't want to fuck with one of those OBD2 dongles though.

Why not?

Most of those I know of come with an approach ramp

[CaminoRacer]

A low profile jack + jack stands is cheaper How often are you gonna use a mini lift to make it worth the money?

[Laconian]

Why not?

Indeed.. they're cheap and really fun to mess around with.

I already have a jack + stands + ramps... no way would I get under a car without that

I guess I don't need this for wifey's car which is a plus. But the G is well over 3500lbs so I'd still need the 5000lb version Only work I would do under her car is an oil change. But w/all the tinkering I do on my car this would be nice, and it's not a bad price spread out over a lifetime

IIRC you had some weird CEL issues with one you got. Plus I am pretty sure with my ricer wheels my speedo is a hair off. I guess that's no biggie in the grand scheme of things. I'd be curious to see how rich this thing runs, gas mileage is so bad.

[r0tor]

I've  thought about a quickjack a few times now... Seems useful

I then reset the CEL light using the dongle.

I have a cheap $30 OBD scanner tool...it does live data so you can monitor all your voltages and temps...coolest thing to me was the % load reading...it live reads the load of the engine.  Not all that useful, but neat.

FYI GPS is only accurate to 30ft or so. I have no inclination to do the math how much distance traveled in that amount of time would be, but it's "possible" you could be shorting 60ft.

Also, I'm confused as to why you'd worry about GPS when measuring time and speed.

[Cookie Monster]

The GPS measures speed....?

[12,000 RPM]

The GPS measures speed....?

Yes... my bicycle computer uses it, and Waze uses it too.

[MX793]

Yes... my bicycle computer uses it, and Waze uses it too.

That's how my Garmin camera determines speed as well (can also link it with the OBDII for a more accurate read).  It can be pretty wildly inaccurate, particularly when trying to deal with rapid changes in speed.  Fine for steady-state driving, but I've seen it be 5+ MPH off in my auto-x footage.

[12,000 RPM]

I was watching Waze while I was stuck in bumper to bumper traffic this morning... it was off by as much as 15MPH at a crawl.

It's weird because I would have thought they would use the on board accelerometer to integrate the speed over time. I would figure that would be way more accurate. I think I have an accelerometer app... maybe I can take the data off of that and do the integration myself

[r0tor]

You can do that with an accelerometer app, but your have to make sure it's dead level (or doing some obnoxious 3 dimensional corrections)

[12,000 RPM]

Oooooooo! Accelerometer app is actually pretty slick.... you can remove G, it samples at 200Hz, and it can output to units of g. Gonna see what it do when I go to Walmart tonight and compare it against my car performance simulator.

Yay, integrals

[12,000 RPM]

Bro I'm geeking. Wifey recently snuck and posted a pic of me doing trig on a weekend morning. I was working out the geometry of my bike's rear suspension to calculate the motion ratio

[12,000 RPM]

Damn.... I am really doing 20K/yr. Getting close to turning over 52K, and I was out of the country/driving the Civic for the first month or so. Really feeling that gas mileage pinch cuhz

[12,000 RPM]

Vs the Civic: OK obviously the Civic is 3rd world compared to this in terms of refinement and it literally has less than half the power. But dynamically the Civic kind of has this thing's goat. I'd say they ride about the same, at least in my neighborhood, but the Civic will carve an arc + rotate where this thing plows (around/through roundabouts at least). Better steering feel and just overall agility as well. At the moment I'm more used to using a manual to manage power through corners as well. I think the right coilovers will tip the win in favor of the G though. Strangely enough I'd call them even on brakes too; Civic with a fresh bleed and.... Stoptech pads?... actually bleeds speed respectably. Definitely going with some more aggressive pads for the G too but that's probably about it.

Was looking back on this thread... wanted to update with the mods (brakes/tires/coilovers). Civic still has this thing licked on turn in and steering feel, by a surprisingly wide margin; but that may just be the consequence of weighing literally 1000lb less G brakes are much better; firmer and way more powerful. Driving the two back to back I realized the Civic front shocks are blown... there's definitely a mid speed resonance "bob". Fucking ST, never buying a KW product again This thing really puts how slow the Civic is in perspective as well... 1/4 throttle in the G is WOT in the Civic. Frustrating. Oh well. Going to try and clean the Civic and get it out on the market soon.

[giant_mtb]

I feel ya.  Was quite the change going from A4 mileage to Taco, though I can put the cheap stuff in Taco, so I figure the money spent balances out.

[Cookie Monster]

What kind of mileage you getting?

[12,000 RPM]

Yea, practicality is nice. Wifey's car has been clutch quite a few times.

What kind of mileage you getting?

Like 18-19MPG, probably 50/50 city/highway. Aggressive as well so it's about what the EPA estimates... I was just hoping to do a little better; like 21-22 on average. Hopefully the alignment and maybe a trans flush will help.
