    So, what are you listening to?

    This one came up on pandora randomly this past weekend. Have not heard it in many years.

    I also brought some stuff home to work on. Stayed after work today to re-clock the new turbo. As long as I had it apart, I decided to clean up the turbine casting in a couple spots that I didn't like. The other one that's not pictured is the inlet to the wastegate. It's just a hole drilled perpendicular into the side of the turbo, so I put a radius on the inlet side. Probably not a huge improvement, but it makes me feel better.

    ECU mounted in a legitimate fashion. This is a first for me. Our neighbor Woody dropped off this Hazard Fraught bead roller a year or two ago and said to try it out. It's been sitting around, untouched, ever since. I'm pretty sure he forgot that he even gave it to us. By mid-day Saturday I'd had enough of dealing with wiring and decided to work on the charge piping for a while to clear my head, so I set it up. I feel a little bad complaining about it because it worked and it was free, but this thing is seriously bad. Out of the box, it felt like picking up on someone else's half-finished project. Didn't come with any kind of stand, nor did it really seem to have any provisions for attaching one. I guess you're supposed to clamp it in a vise? Doesn't really work with where our vise is. Aside from the obvious pinch-point on the business end, there are some nice chompy gears waiting for an opportunity to get you on the other end. The edges of the female die was sharp enough to cut yourself on, so I had to chuck that up in the mini-lathe and used a file to round off the corners so they wouldn't cut into the pipe while it was being rolled. The irony of using a HF tool to fix another HF tool was not lost on me. It worked though, so that's one thing off my list.

    Hagerty BMW Price Guide (2019 Edition)

    E28s aren't even listed at all? Maybe they're off the bottom of the scale? Sorry, @YoungCR 🤣

    Hagerty BMW Price Guide (2019 Edition)

    Fun to look at. I figured e21 would be the lowest, but it looks like we narrowly beat out e12s, depending on condition. Woohoo! Not last place!

    Knock Detection “Det Cans” $20

    Proof of concept! I wired a knock sensor up to a guitar practice amp which has a headphone jack. I haven't tried it on an engine yet, but I did spend about half an hour clamping the sensor to various things around the shop and tapping on them with screwdrivers and such. Actually worked even better than I thought it would, plus I have all the material I need to make my own ominous tones album. The only issue I had was when I plugged the amp into an outlet that wasn't grounded I got a lot of hum. How well did these work for you? This looks a lot more convenient than dragging around a practice amp and finding a place to plug it in...

    If I get the car to the picnic, it will be on a safe DIY tune. Once I prove out that everything is working properly, I'm hoping to rent dyno time somewhere and do the tuning myself. I guess it all depends on how comfortable I feel once I start dabbling with the tuning software. Conceptually, I have a good idea of what needs to happen, it just depends whether or not I feel confident executing the plan myself at that point.

    Looks like the sign has landed on my car this year... Thanks @GunMetalGrey

    This excerpt from one of the TE docs gives some idea of what the target condition should look like: Aside from this, I also have the IPC-A-620 book sitting on my desk at work. The IPC spec lays out inspection criteria in excruciating detail. Wire doesn't extend past crimp area? Defect. Crimp extends to the edge of the crimp area on the insulation side so that there's no "bellmouth"? Defect. Wire nicked slightly while stripping? Defect. Basically, if it's not perfect, it's not good enough. I'm on a couple "motorsports wiring" facebook groups, and if you even mention IPC on there, you'll pretty much get laughed at because it's not whatever MIL/NASA spec that those guys claim to be using. The money and time invested gets to be out of hand pretty quickly, but if you're spending crazy money to go racing it's cheap insurance vs getting a DNF because a crimp failed. I'm just shooting for something close to OEM standards... In case anyone is interested, this is the most referenced page on the internet when it comes to "motorsports wiring": https://www.rbracing-rsr.com/wiring_ecu.html Best part of the page IMO is the picture of this woman from the 40's with the bad-ass hair:

    The terminals for Bosch connectors are an F-crimp. The crimper you're thinking of crimps from 4 sides and is used on circular contacts such as Deutsche connectors.

    The one they sell is just a generic crimper. Both of the crimpers I'm using are racheting that won't release until you applied enough force. They should be more consistent as far a the force applied to the crimps. The generic ones rely on the users judgement to decide how much pressure to apply. I believe the smaller terminals will work better, but the real problem is just that I have access to too much information as far as quality standards go. Even the bad crimps that I did last weekend we're good enough that the wire was breaking without pulling out of the crimp. Even so, electrical problems are a PITA, so I'm doing my best to avoid them.

    Crimps! I tried a couple different crimpers, but wasn't able to get anything I was 100% satisfied with. The 20ga wire on the Haltech harness is right on the edge of the size range for the contacts I'm using. I'm going to order the smaller size to see if it works any better. Anyways, as long as I was at it, I decided to do a basic pull test on them. I don't have a force gauge, so this doesn't really tell me much. It was fun though. I was going to re-use most of the connector housings from a stock harness, but it turns out that removing the contacts from the housing is nearly impossible. Also, half of the fittings I ordered for plumbing the oil and coolant to the turbo didn't work for one reason or another, so it doesn't really feel like I accomplished anything this weekend. Still have a 21 item long list of things I need to order tonight...

    Because it looks cooler 😀 I should have put some light on the e36. It is kind of hiding back there.
