Note the smooth, non-ferrous and non-toothed drum which is invisible to the sensor - allowing the internal reluctor wheel to be measured. https://images.squarespace-cdn.com/content/v1/681197026b86085cb548e5e8/ef411b55-89ff-416e-89b3-977302a5acd7/electric_machine.jpg Projects - Hybrid ZF8 Swap - Part One: The Hardware - Make it stand out The electric machine which goes in place of the ZF8s standard torque converter, for hybrid applications. https://images.squarespace-cdn.com/content/v1/681197026b86085cb548e5e8/37a21ec1-602a-42f5-86ad-b7194112c148/elec_pump.jpg Projects - Hybrid ZF8 Swap - Part One: The Hardware - Make it stand out The auxiliary electric oil pump, used for take-up. https://jonolaivar.me/projects/tjet-swap monthly 0.5 2025-09-30 https://images.squarespace-cdn.com/content/v1/681197026b86085cb548e5e8/57feece6-3631-433d-ab37-9a72e1c66974/engine_apart.png Projects - USDM Fiat 500 Abarth - TJET Swap and Standalone ECU Conversion - Make it stand out The engine in the most disassembled state required of this swap. See, its not that bad, is it? https://images.squarespace-cdn.com/content/v1/681197026b86085cb548e5e8/0d78bd10-a498-41b6-9de3-79d11347b539/tjet_carrier_underside.jpg Projects - USDM Fiat 500 Abarth - TJET Swap and Standalone ECU Conversion A side by side look at the USDM MultiAir cylinder head, and the Euro TJET cam carrier. Notice that the cylinder head has an additional oil feed port (circled in red) which has no corresponding interface on the TJET carrier. Without being plugged, that would certainly lead to quite the disaster. https://images.squarespace-cdn.com/content/v1/681197026b86085cb548e5e8/9fac4b83-1a62-4548-95d8-3bd83fc7dc60/multiair_cylinder_head_top.jpg Projects - USDM Fiat 500 Abarth - TJET Swap and Standalone ECU Conversion https://images.squarespace-cdn.com/content/v1/681197026b86085cb548e5e8/1358b550-4afb-4151-83f1-69a35af509b8/hss_lss_circuit.png Projects - USDM Fiat 500 Abarth - TJET Swap and Standalone ECU Conversion As "high side switched" and "low side switched" are common descriptions in the following section, I figure it would be helpful to cover what exactly that means beforehand. With a low side switched configuration, the component is always connected to 12V (though in most cases, there's an additional main relay which disconnects power to all low side switched components whenever the car is in a fully shut down state). In order to enable the device in this case, its ground is connected to...ground, thus completing the circuit and powering the device. This is how the fuel injectors work, for example. In the high side switch configuration, the device is always grounded, and is controlled on the "high side" by connecting power to it when it needs to function. Neither one of these two control methods is better than the other per se, but depending on the application, one may be advantageous from a circuit, component, and ECU/Control Module design standpoint. https://jonolaivar.me/projects/hpfp-control monthly 0.5 2025-09-10 https://images.squarespace-cdn.com/content/v1/681197026b86085cb548e5e8/c2d4c542-a647-4fb5-8d9f-12041047b64a/frontpanel_speedcorr_02.png Projects - Direct Injection High Pressure Pump - Standalone Control - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/681197026b86085cb548e5e8/46f3a844-1597-4c82-9f88-fa706484c3cb/labview_frontpanel.png Projects - Direct Injection High Pressure Pump - Standalone Control - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/681197026b86085cb548e5e8/ca9cbf49-2a5a-40cb-8ecb-2e71c4a4a7d3/fpga_main_2.png Projects - Direct Injection High Pressure Pump - Standalone Control - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/681197026b86085cb548e5e8/f1ef1c7b-ef27-479e-b940-fd60507bb288/hpfp_internals.jpg Projects - Direct Injection High Pressure Pump - Standalone Control - Make it stand out A view of the internals of a modern, single piston, high pressure fuel pump. Note that the pumps piston features a black, DLC coating to combat wear and promote sealing performance. https://jonolaivar.me/projects/ionic-current-combustion-analysis-a-quick-overview monthly 0.5 2025-07-22 https://jonolaivar.me/contact daily 0.75 2025-07-22 https://jonolaivar.me/welcome daily 0.75 2025-07-14 https://images.squarespace-cdn.com/content/v1/681197026b86085cb548e5e8/cfe03553-387e-498c-ba64-fd87329f1d39/jon_aboutphoto.jpg
