Building the test harness (woot! - it's built!)

Building the test harness (woot! - it's built!)

Progress on the test harness has moved faster than my blogging. ūüôā ¬† I'm excited - harness complete and used to test three¬†OEM cold start timers. One works. The other two have peeling solder traces. Fixable but I won't spend time right now repairing them¬†- once one spot is fixed its only time before another bit pops up. ¬† Super interesting to see the behavior of the system. I'll document it so that folks know exactly what is happening when you turn the key. Have to say it's di

Examining the OEM Tii cold start circuit board

Examining the OEM Tii cold start circuit board

Prior to building a reproduction Tii cold start timer box I examined the two boards I have.   Both are out of '73's and are identical in general appearance.  By that I mean they appear to be the same circuit board schematic and all passive components are present. Here is the front and back of one of them:   However, the values of some resistors and transistors vary between the two boards. Could be several reasons for this - the system is much more forgiving than I realiz

Ground Control struts

Ground Control struts

Welded on the Ground Control bits, installed the rebound adjustable Koni inserts, Eibach springs, GC camber plates. These are the e30m3 struts but it's the same for the 2002 guys.   The rear is interesting, between the 02 chassis and the e30m3 subframe I need springs in the 11 to 13 inch long range...   All of this is temporary until I get around to another set of MCS dampers. Loved them in the tii, they're just super ultra mega.

Spare Tire Well

We replaced the spare tire well, as it was rusting.     We bought the replacement from Wolf.  They sprayed the color and shutz in the way the factory did.  Thanks for the tip from Andrew Wilson on that.

Steering wheel cover

Steering wheel cover

I've been able to tackle some projects I've been wanting to do since the car got hit including wrapping the e21 steering wheel in new leather.  I love the look leather steering wheels that have a bit of age to them so thats what I was going for. This turned into quite the task but im happy with the outcome.  I found the leather scrap at local upholstery shop, dyed it a dark brown, and hand stitched it. Let me know what you think.

Final Product

Reggie's wife Stephanie took some nice pics of the car after it was all cleaned up.  So photo credit goes to Stephanie Stewart.     Car came out great.  Nice to know it is solid underneath, once again.  Hope it lasts another 50 years!

Painting, Body Shutz

Reggie's used the same DuPont paint that was used in the early '90s.  They used the door to create the match, since they could see it from all angles, and get good light on it.  The paint match turned out pretty nice, I have to say.  They did a great job.  And I didn't have to spring for a full repaint.     Here's the various coatings, etc, that were used, from an email from Reggie: Behind and in-between metal that will no longer be accessible, we use a weld-through primer, w

Driver's Side Part 2

More pics of the work on the Driver's side of the car.  We thought this would be the worst side, but that wasn't entirely accurate.     The rockers were pinched-welded as you can see, like the factory.     Real goal was preserve the car, not restore it.

Driver's Side Part 1

The plan was to replace both rocker panels, and the spare tire well.  And anything else that the excavations turned up.  We knew we would find more.     Thanks to Reggie Stewart - his shop Reggie's Motorworks did the work.     Also thanks to Paul Wegweiser, who supplied a lot of the parts via Maximillian's.     Special thanks to my wife for supporting me on my expensive hobbies!   Here's what was found on the driver's side.  Work was needed on the lower pa

Before...

It all started with a two rust bubbles.  One on the bottom of the passenger door, and a more serious one on the bottom of the driver's side rocker.  That one was the outer rocker beginning to rust through.    While I have owned the car since 1987, it was a daily driver before that.  So probably a good 17 years as a well-cared for daily driver.  So when I bought it in '87 I knew it was fairly solid, but not perfect, in terms of the condition of the body.     And over the years

Initial thoughts on the Tii cold start timer box

Initial thoughts on the Tii cold start timer box

We've had two '73 Tiis for about 20 years. Neither car has working cold start timer boxes. Both have the manual cold start injector bypass button under the dashboard.   Both cars run well and always start. They have been without a timer box for so long I stopped thinking about it.  But I started to think about it a few years ago as my interest in low voltage electronics increased.   I originally considered about modernizing the timer circuit. Build it out of a micro-controlle

And the waiting has begun

And the waiting has begun

Or what do you do while you wait?   The body is at the painter for some light body work and paint. I expect it to be there for a couple months. Maybe more. I did tell them that I wasn't in a hurry. Mainly because I haven't figured out where I'll put it once it's done or where I'll reassemble Betty. Garage space being what it is right now.   So, I have time on my hands in regards to working on the car. So, what do I do? Well, I have several parts that still need rest

Now for something completely different

Now for something completely different

So I am pretty sure that I am going with a MS3 Gold box, so the autotune function needs to be run by a computer so I integrated a Raspberry Pi 3  and a screen into my replacement center console plate. The Pi will run Tunerstudio,  the prefered software for tuning the MS3 box. It will also run a nav app as well as perhaps some a/v.  I integrated a GPS module that can also be used for 0-60, perhaps an accelerometer is in the future. And will also have an Echo Auto as well, just waiting for some us

A few pics of the weekend’s activity

New hardware on front subframe. Bushings are about two years old -  think they need replacement already.    Separately I started   to get the pedal box ready for install, but then wasn’t satisfied with the engine bay. So....back at it.

Moving is not easy

Moving is not easy

A few months ago Jo and I decided that we'd like to sell our house of 21 years and buy another in town that would be our forever home. In 21 years, you collect a lot of stuff. Too much stuff as it would turn out. Since we hadn't done it in a very long time, I'd forgotten just how big a pain in the rear moving is. So, on top of all of our house stuff, I had 3 cars to move. One of which, Betty, was in parts all over the garage. Most of it was already in boxes, bagged and tagged. But a lo

In need of a shell

In need of a shell

I got in an accident a week ago in the 02.  Got hit at an intersection by a guy that ran the red light.  As you can imagine im pretty devastated but trying to be optimistic.  It can be fixed but its gonna take a lot of money.  I spent the last couple years restoring the car on a budget including a new engine, 5 speed trans, new interior and paint.  What I think I want to do is find a shell and swap all the parts from my car to the shell.  If you have any leads on a shell with minimal rust, pleas

Rear Subframe Refurb, Rear Brakes, and Suspension

Rear Subframe Refurb, Rear Brakes, and Suspension

While the car was cut to pieces, I spent time rebuilding the rear subframe and related parts. It was a nice break from all the grinding, cutting, and scraping on the body. The rear subframe was sand blasted by precariously hanging one end out of a HF sand blaster with a few trash bags strapped to the side to contain the dust. It was then primed with corroseal and coated with a few coats of brushed on gloss enamel. The same treatment was given to the differential case, diff bracket, and rear cont
