As you may imagine the CAD and measuring process for the Jaguar AJ-V8 has been very slow.
Apart from the fact that every dimension seems bigger than my height gauges or micrometers, it’s a little complicated!
So far I’ve measured and modelled the cylinder heads, rocker boxes, front cover and bell-housing.
There are an awful lot of bits to go! If I even look at AutoCAD, I get depressed about how big a task it is. The DWG file is already huge and takes 2 minutes to load.
There have been further advances. I have worked out which Megasquirt MS3X components I need to get it fired up. Although, I am still a little confused on whether to use an American EDIS 8 setup for the ignition.
The Megasquirt MS3X is an after-market ECU that you can build from bits.
The engine I have, is an AJ26S, which as a 12 pulse flywheel. The later model AJ27S and AJ34S have 36/1 pulse automatic flywheels.
However, the flywheel will be replaced by a manual gearbox hybrid Nissan Skyline item. Therefore a 36 pulse, crank mounted trigger wheel will need to be fitted.
The Cams are one pulse per revolution, this will allow sequential fuel injection
| MS330-K | Megasquirt-III kit with V3.0 PCB |
| MS3Xpander | MS3X expansion card |
| JimStim-K | JimStim Stimulator kit (for testing) |
| StimPower | Power supply for JimStim (for testing) |
| MSHarness12 | 12′ main board wiring harness |
| MS3X-Harness | 12′ MS3X wiring harness |
| IATwPiggy | Intake Air Temperature Sensor |
| 38NPT-Bung_A | Aluminum bung for IAT sensor(Also available in stainless steel) |
| MS3TuneCable | USB communications cable for MS3 |
I will have a better look at a few of the sensors, so the above list may grow or shrink a fair bit.
There will be a break from any further design work, as we’re off to Europe to do a bit of back-packing.
