    Building an Arduino tachometer 1HDT to 2H RPM gauge

    Way above mine as well! I have to say Claude AI is absolutely amazing with such projects been working with several AI but claude comes on top.

    Building an Arduino tachometer 1HDT to 2H RPM gauge

    I think I'm at a point where im learning so much from this project i would much rather do it full DIY. This project triggered another idea i will start with when I finish this one. I will connected a blue tooth controller to various lighting etc and can basically control camping lights, water...

    Building an Arduino tachometer 1HDT to 2H RPM gauge

    So updates since my last. I am struggling to get the DIGI-Frankestein-thingy i did to talk to the gauge. I was able to get a 817 converter and although the input side works great (0 to 5 volt cycle depending on frequency cycle) the 12 volt output remains constant. The idea is that the 5v...

    FJ62 with 1HDT wirings and gauges

    Yah built a DIY converter, here is thread link. https://forum.ih8mud.com/threads/building-an-arduino-tachometer-1hdt-to-2h-rpm-gauge.1382700/

    Building an Arduino tachometer 1HDT to 2H RPM gauge

    After fiddling with 2N2222 NPN transistor i decided to swap it for optocoupler PC817 between Arduino and 12V side. This should isolate the ground and eliminates grounding conflicts and hopefully get the 2H RPM gauge working.

    Building an Arduino tachometer 1HDT to 2H RPM gauge

    My FJ62 originally came with a 3F petrol tachometer. I swapped in a 2H diesel tachometer gauge (same RPM range, but meant to be driven by the correct diesel signal) for better accuracy. The injection pump is a Denso VE6 (22100-17290) carrying a 1HD-T 2-wire variable reluctance (VR) sensor — not...

    Media 60 series porn (pictures of the kind that get people like us excited!)

    Nah much smaller event local not international but very cool. We drove outside race track to stop and view the racing cars.

    What did you do with your 60 this weekend?

    AC low pressure swap, aftermarket ac fan installation on a cut out relay box and took the bloody dashboard apart since AC blower fan was not running on full speed. Finnaly found the speed switch contact needed some cleaning and light sanding 9 hrs later 🫤🫤🫤🫤. I must clean everything at some...

    Unable to start 1hd-t without battery booster

    Had a very slow crankcase myself, I swapped the battery from 64 amp to 80 amp and what a difference that made. Im running 12 volts since the engine is installed on my fj62. The other factor that helped a lot with pump timing, now prerry much cranks in 1 or 2 engine cycles with out glow plugs...

    1HDT troubleshooting / diagnostics after engine swap from 3F

    Tested my new setup offeoading. The Nomad handles much better, but I must adjust the pre boost fueling car struggles prior to turbo boost (dies a lot unless I have a press fuel pedal aggressively leading to excessive spinning or engine dies. Seems I will need turbo boost diesel adjustment...

    Offroading by that magic lake .... Next time im bringing my swimming suit... And bogged at the magic lake ... Lesson learned rear wheel drive on soft sand with 18 psi will get you bogged down... Forgetting to engage 4x4 is not a good excuse. Needless to say my friends all hurried to take...

    What did you do with your 60 this weekend?

    Proving yet again my amazing driving skills getting bogged down with my kids. Amazing offroading with friends and tackled rockcrawling for the first time with my 60.
