Frame held to foam with rods and hog pins. Using a screw driver, I pushed the rod against the frame and then put a hog pin on.

Image

Seat base done
Image

Give the seat base a brush down
Image

Image

As I swaped the passenger side base material to the drivers side, I needed to cut out a hole for the bolt hole on either side. Note, you can't swap the frame over as there is provision on the drivers seat base for the vertical lift mechanism.
Image

Find the hole

23 November 2015

A NZ GT Four Club member came over to inspect the RC's ECU. The caps in their RC had leaked and blown a track on the board. They needed to look at mine to identify where the track went.
Image

Image

Since the ECU was out, I decided to send it up to Auckland to a friend to get all the caps replaced.
Image

Firstly I provided him with these cap values: 2x 10uf50v; 15uf35v; 100uf10v, 33uf35v; 220uf10v; 47uf63v
He said he had them in his workshop, so the ECU refresh was a go.

Interestingly, he has the equipment to read and write EPROMs, so we had a little conversation about modification of Toyota ECUs. What was interesting was the ability to design custom boards and get them prototyped in batches of 100 or so. So there is the potential to create new RC ECU's if there was ever a need. But after some analysis, there really was little value in doing so as it was just as easy to buy a MegaSquirt or move up to a Link or Haltech due to the prototyping cost.

Once the ECU was in Auckland, Dee had a look over the ECU. He noted the following:
- Just doing some research. These eeproms looks to be masked which means if I try to read it I will get garbage for data.
- Ecu does have a moisture barrier/conformal coating. Looks to be laquer based as isopropyl turns it sticky.
- All the caps are done..im working on thr eprom now. I trying a slip on chip adaptor before i try desoldering it. I should be able to read it without pulling thr chip. Saves melting the lacquer coating and making it look like a mess.
- Its garbled data. The chip has a toyota specific part number so i cant manually identify it. The auto detect mode on eprom reader reckons its a 27c512 chio but data comes back as garbage.

After that, he did ask about setting up a simulation bench so he can probe the logic. But too much effort and I was on a schedule as I was picking up a new project car in Auckland that weekend.

Here are some photos of his work:

Had some issues fitting the exhaust system once everything was hanging from brackets and flanges were bolted up. Decided that I needed 10mm in a straight section, so the exhaust came out and I added a 10mm secion of pipe. Respray in heat temp paint and reinstalled with new gaskets and exhaust sealant.
Image

Image

December 2015 - March 2016

No work on Pearl was done during this period of time. Promotion at work = more work, Christmas in Australia with my sister's family, and I decided to install a decent stereo system in my daily driver.

Stereo system in the car was a project in itself. Two months to do and I still haven't installed the sub yet lol
- Pioneer P99RS competition headunit which can be controlled by steering wheel controller
- 3 way active front speaker set up using custom speakers in factory locations with full sound deadening
- rear custom speakers in factory locations with full sound deadening
- re-wired the car for active speaker setup
- built amp rack for high end amps with fan controller system

Back to work on Pearl. Inner CV boot was torn. Time to replace the boot and regrease the inner CV.
Image

Image

Image

26 March 2016

Nick wet vacuumed the passenger seat as it was pretty manky.
Image

Image

Disgusting to say the least
Image

A clean of the headliner was also in order. Disinfectant to start.
Image

Image

Time to fit some mesh on the bumper and bonnet.
Image

Spray it black before bonding to the bumper.

Install side mesh insert which were saved from the original bumper. Cleaned up and sprayed black
Image

I wanted to see if the RC centre mesh could be used in the new bonnet. I ended up cutting off tabs to test fit
Image

One of the final pieces of the interior was the missing glovebox
Image

Tried the orginal mesh in the fibreglass bonnet, but the mesh was warped due to the crash. Time for some replacement mesh.
Image

Nick bonded in the spray painted bumper mesh
Image

Tried fitting the bumper but had a number of issues with fitment. Took bumper home to mod

April 2016 - May 2016
Bumper sat on the workbench at home for a couple of months. Got busy, unmotivated and at the start of May, fell down some stairs, so really screwed myself up for a month with a sore head and bruised leg.

3 June 2016
Finally I was up to standing for long periods of time and got back in to the garage after a call from someone who was enquiring about purchasing Pearl.

First things first, time to sort out the bumper fitment.

Got my aluminium crash bar and original RC bumper and checked clearances with the FG bumper and mesh.
Image

Image

Image

Trimmed some of the mesh
Image

Tried fitting the bumper again, but again, no success.

After looking at the flanges to the side and thinking they were too thick I removed the side brackets to sand the FG flange down a bit. Reattached the bracket once I finished sanding.
Image

Decided that I needed to test the original bumper and aluminium support and so packed up the car with a bunch of stuff and headed back to Nick's. Bought some lights to work outside. Ended up being 5C and foggy that evening..

Nick changed the plint backing on the back as there was some adhesive left from a *bleep* bage left over. Pays to have spares around my garage
Image

Testing supports next to each other revealed nothing new. Pearls support was not bent/warped in the crash - phew!
Image

Honestly, Pearl spends half her time with body work off. Had to remove the guard as I snapped a bolt off in the guard so we needed to get it out.
Image

Decided to fit the fibreglass bonnet
Image

Nick removing said broken bolt after I drilled a hole in it at home.
Image

Bumper finally fitted on passenger side and bonnet trim added. Starting to look like a car. We still had bumper fitting issues though with the drivers side not fitting. Initially we thought the chassis rail was warped due to the crash or the guard was warped. After looking at the design of the original RC bumper and even test fitting it, we determined that the shape of the bumper at the bracket point couldn't flex due to the flange in place. The bumper, around the indicator area, does flex a bit and the FG bumper could flex with a bit of effort as well.
Image

Back to the bracket. As you can see, the flange is quite thick. 4.6mm if I remember. The stock flange is around 2.5 - 3.0mm or so.
Image

As you can see, the thickness is uniform along the flange. Obviously the moulding wasn't perfect and the shop added more material on to the flange for strength.
Image

Drilled out rivets again
Image

Dremal time
Image

Trim down was more intense this time with more measurements and test fitting of the bracket
Image

Better fit of the bracket
Image

And success! Everything was fitted up. I let Nick put the licence plate on as it was a huge moment for both of us to get to this point.

I fixed up the glovebox as well which required swapping the latch and swapping out the locking mechanism which is for Elephant.

So time to start the car and give it a shakedown on the road. Clutch needed pumping a lot to get it in to gear and then on to the road for a proper test. Drove for 15 minutes and when I got back the car was smoking and steaming as the paint on the exhaust flashed off and the rust build up on the discs was removed with glazed pads. Quite funny to see it smoking from the underside of the car.

Time for a wash! Needed to get rid of the grime and brake/rust on the wheels.
Image

Image

Image

Image

So after Pearl's wash, it was time for a shakedown out to the coast to see how the car was tracking and to check if the ECU would throw any codes. Of note, the speedo was way out, and is something that needs to be fixed before going for a warrant of fitness and road registration. Apart from that, there was various squealing from the brakes as they bedded in.

And some shots to show off to the prospective new owner

Finished up the evening by parking up and chucking the cover over.

And so Pearl is back up and running and nearly everything is fixed up.
Only things to finish are to fit the bonnet washer jets and fix the speedometer issue.

I wonder if the speedometer issue is due to the cap replacement, but I will swap in another gauge cluster to see if the original gauge cluster is the issue.

So now after 237 photos of the past year, you are now up to date.

Cheers, Dave

Missed some updates last night. I think this is the to-do list now:
- Gearbox is also has a notchy 3rd gear. I'm thinking that the gearbox fluid also needs to be changed.
- Handbrake needs to be tightened
- fit washer jets
- fix speedometer
- fit undertray panels from the NA (close, but not the same as standard GT Four ones)
- poss fix the drivers side seatbelt as it isn't retracting very well

I have considered keeping the RC around, but just don't have the room or the time to keep working on it. Especially since I bought this at the end of 2015 ;)
Image

Yes, I was stupid and bought a 1977 Fairlady Z. Needs a lot of work, but you have to live the dream, right?

The RC has been hanging over my head for a long while now and needed to be finished up and moved on. Lack of motivation and more work to be done to get it to a spec where I'd be happy, and actually not worth the effort as I have the Elephant to finish and the Z to start.

ECU was interesting - good to have friends who have the skills. Lots of discussion on reverse engineering the ECU, but really the effort involved would only be good for a DIY person who was interested in that type of thing.
Technology has moved on, so we should move along with it as well.
