Good evening fellow land cruiser enthusiasts, I have designed, now almost 2 years ago, an electronic replacement for the "superglow timer module" that failed on my BJ42 (3B engine). It is a direct replacement for 9pin modules (28521-57010). I shared the development issues and success on this...

Hi Kevin, I don't have any 12-HT under my hand but as far as I understand they share the same philosophy of pre-heat and post-heat, along with a timer that seems quite similar to those on glow/superglow systems. What is the serial number on your timing module ?

Hello, As some of you may know I have retro-engineered and designed an electronic replacement for our beloved superglow systems (see Superglow electronic replacement - https://forum.ih8mud.com/threads/superglow-electronic-replacement.1323121/). The manual is available here . I initially made...

For the sake of clarity and good understanding of the superglow system I would like to correct that :) Superglow has 2 phases: preheat and postheat. You should wait for the preheat to end (which is materialized by the dashboard light extinction) before starting but the superglow will not be off...

Hello, I made quite a significant dive into the superglow system, having it retro engineered (see this post)... But as far as you describe it yours seems to be operating fine. If you indeed have an alternator issue check your car battery voltage while powered off. In case of a low battery...

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 :) Kouglof

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...

Hi, A few things to help you diagnose your system: - When you say the engine starts fine, in what kind of temperatures is that happening? Is it starting rougher on cold mornings ? - You mention 1.5 to 3.5v at the busbar, is it between busbar (any glow plug) and ground ? If so this is...

After deep testing on bench and in car I can proudly say that my electronic superglow works great ! Here is a picture of the final board inside the timing box: The card in detail: I switched to transistors for increased robustness. I also added a bunch of improvements including a monitoring...

Sooooo After my last tests I made a 3rd version of my superglow electronic replacement. I fixed all identified hardware bugs and made global improvements (stability, power supply variations,...). I added a wilson switch port that does not need the board to be functional in order to work. I...

Hi everybody, I have been testing my system this weekend (I don't live where the car does unfortunately...)! It is rather promising but I have some stability issues regarding power input. I have to diagnose where the problem comes from. I'll keep you updated.

Is your 12v connector different from my 9pin connector on the 24V system ?

Actually I would have little use of the board itself, especially if it is not in working condition. To adapt the board to the 12v system I would rather use the timer manual with the temperature curves if you happen to have it. Considering connectorless board that is obviously possible though I...

As you have noticed the connector on my picture is the one coming from the old stock timer. The good news is I managed to source the original connector (171894-1 is the reference) thanks to a lot of research on specialized websites. So I would be able to manufacture a board with a connector. In...

After enduring too much trouble with my original superglow timer which frequently did not operate correctly I decided to use my electrical engineering knowledge to make a timer replacement. This board is based on an ATMEGA328P for the logic part. Current features support: - Water temperature...
