Megasquirtin

I finished building the MegaSquirt ECU last night. I went with a V2.2 board for MS1. The other box its connected to is the MS relay board which is a great convenience. I chose to use a relay board instead of the stimulator to test and that worked fine. The assembly was very well organized and the board tested fine at the end so I can't wait to get it in the car and turn the key.

Here it is in its finished state:

Porsche 956 in the flesh


Went and had a look at a Porsche 956 being race prepped by Wayne Park auto @ Milton. I spoke to the mechanic who was dismantling the gearbox and he mentioned that it was stuck in 3rd. Amazing engineering, great to see it with all the cowling off.

Check out the pilots, none other than the "Ringmaster" Hans Stuck and Ukyo Katayama, who drove for Tyrrell. I don't know anything about Schuppan.

Intake and exhaust

Got the exhaust and most of the intake sorted on the car this (long) weekend. Looks like another day of hard work to get it all done. Making the flanges and pipe angles took the longest time, you can see some of them half done in the photo below. I'll clean them up and paint all the pipe before it goes on the car.

911 brake rebuild



Just about finished the brake rebuild on the 911. Of particular difficulty to acquire were the channel seals that go in between the caliper halves.

New seats for the 924




I've just finished installing brand spanking Sparco Sprint seats in the toofah. They are much harder to get in and out of than the previous seats but once you are in, you are very firmly in.

911 ECU mounts

Progress on the 911 has been slow but constant. The biggest piece of work this weekend was mounting the ECUs up in the passenger compartment.

Here is a picture of the engine bay stripped of its rats-nest wiring loom. Note the 3.0L intake installed for its TPS compatable throttle body.

To date we have:

Pulling or Pushing?

So I was making some brackets for the new seats in the 924 and decided to experiment with my gas MIG welding technique a little. I usually start the weld away from me and pull the weld pool towards myself as you can see the puddle easier. This first picture is the pulling weld.

I have read that you get better welds by pushing, that is starting closest to you and pushing the puddle along. It seemed to produce a flatter, wider joint but was harder to see and control. I might push where possible from now on.

Real "Guitar Hero" controller.




Got a mates wedding coming up, and he and his missus love guitar hero 2 so I decided to build them a present. Its a chinese strat copy guitar that will be modified to contain the buttons and circuit boards of the out-of-the-box guitar hero controller.

Gutted the controller and donor guitar, removed the jack and widened the hole for the rubber cable grommet:

Cut away material to make space for the main board:
