Yep, generally it seems like they didn't skip thoughts about maintenance and accessibility. It wouldn't seem that way at first (especially with the badging) but there hasn't been anything really frustrating working on the car yet. Same was true on the free 528i.

Good news is I got my wideband hooked up with my logging software. Amazon sold a usb serial cable that said worked with my PLX. Technically it does, but only after you splice it and swap the wires for the tip and ring of the 3.5mm headphone jack. Receive and transmit were swapped.

I've been wanting to learn how to do properly cut/buff paint for a long time. I decided to pick up a Griot's Garage kit from Autogeek with a G9 polisher and everything needed to follow their 3 step polish/compound/wax process. Being a data junkie I also picked up a paint gauge so I have an idea of where I should go easy. On my wife's Jag the paint was on average 300um with the thickest paint being on the trunk lid. On my M5 it went from about 100um at the kidney grills to 175um on the trunk lid. I decided to test the kit out on the Jag's trunk first and even through it had visible scratches, I didn't even need to use compound. Next I tried the M5 trunk which needed quite a few passes with compound to work out the spider scratches. I measured the thickness during the process and was pleasantly surprised about how little I knocked down the clear. Eventually, I'll continue the process on the majority of the car. The trunk lid is on the left and quarter on the right in the gif below.

Results with the buffer are amazing aren't they? I couldn't believe the difference in the black paint on the SSEi when I hit it with the compound. Since you're going to the trouble of paint correction, you might as well lay a ceramic coating on it. Correcting the paint is the hard part, most time consuming, of putting on a ceramic coating. You'll be practically there! Been happy with the coating I put on the SSEi and the Civic so far. Still beading water.

I can't argue with that at all. Looks Armor Shield is getting added to the list.

I actually smoked my cutting pad today polishing my headlights prior to ceramic coating them. I went to take the pad off the backing plate and it was more or less melted on there. Oh well. Learning experience. This was my second go at restoring these headlights. The hard coating areosol Meguiars sells ended up being hazy like some of the reviews mention.

Thank you. That was my first time bringing lenses to a full polish then sealing. The other times required a haze for the coating to stick.

I actually got the bumper back from a respray last week. Here are some before/after.

I only snapped that one after shot. I've been focused on logging/tuning with this car and the Ducati in my spare time.

I'm primarily messing with WOT A/F on this one but I also re-wrote the hex to enable sport mode memory (to stay on with key off cycle) and to change the dash oil temp warm up lights on the tach to coincide with the oil temp in Celsius. 4k - 40* or less, 4.5k = 45*, etc. Originally it was 0 through 60*C. Now it's 45 through 60*C.

Here's the tach lights extinguished once fully up to temp.

Are the tach lights a limiter as well or just a warning?

In the S2000, if you try to get into VTEC before you have 3 bars on the temp gauge (considered warm), you hit 6000 rpm like a brick wall lol

Repaint looks great! Between the bumper and headlights car looks like it lost a decade for sure.

Thanks. I was impressed with the color depth on the bumper. I'm hoping to get a little of that back with the rest of the car.

The lights are just a warning. I like the idea since the engine was designed for and runs 10W-60. It'll take a little longer the get the oil up to it's operating viscosity.
