Superglow electronic replacement

[Jag Ln61]

Just to be sure to understand what you are doing:
- 2LT engine --> 1KZT
- What kind of glow plugs do you have in the 1KZT ?
- How did you connect the glow plugs on the 1KZT together ? Kept the original rail and then connected this rail to the output of the current sensor on the car?
- What is the glow plug timing controller ? 2LT original ? 1KZT (I don't know them) ? other ?

The glow plugs and current sensor are purely passive resistors.
You cannot really "bypass" the current sensor as it is only a metal strip.
If you don't plug the current sensor wires it will not disturb the operation of the glow plugs, provided you have an adequate timing controller.

In any case I would not even try to tinker with legacy timing controllers (like 2LT), especially if you are changing the operating voltage or plugs nature. They are fully analogic, sensitive and operate based on quite unstable impedance equilibriums so there is no way you would get a satisfactory result.

If you have a specific and simple enough need for your glow timing controller I may change a few software parameters and make you a custom version

Thanks a lot for the direction, I thought it was a simpler system, but after your reply I did a bunch more research and it seems the plug resistance and the current sensor help determine some parameters for functionality.

To answer the questions;
- Correct, 2LT to 1KZT engine
- Using standard 1kzt glow plugs currently
- I first connected the original 2LT wiring harness with the 1kzt original glow plug rail, this did not function very well, nor did the relays seem to operate as they used to on the original engine.
- I'm using the original 2LT controller, it is a superglow system the same as the landcruisers. I have found some oem wiring diagrams etc which I can send to you for reference.

If you are able to help with a custom controller that can utilise the standard wiring it would be amazing! I don't really want to disturb or change the oem wiring too much. I will send you a message over the weekend with some pictures of my controller and plug etc as a starting point to get your thoughts.

Cheers,
Jag.

Send me pictures of:
- the controller with the serial number
- a plug
- the global installation of the preheat system on the engine

There is no reason you can't make that work

Did you get any further on this? Im doing tha same job, and i wonder how I can fake the current sensor on the 2LT.
