Default Adaptronic Ignition and Spark

Sooo this is a pretty interesting subject just because I haven't seen any example of aftermarket ignitions for the 1UZ... well in depth anyways. I assume I'll be using the stock ignitors. The one thing I'm really excited about is that the Adaptronic uses the crank angle sensors and cam sensors that are factory from Lexus. This is good news because I really didn't want to screw around with mounting a trigger wheel and welding teeth on trigger wheels to modify them to work with the ECU. I've seen people use the Ford EDIS system and this require a lot of screwing around with.

This Adaptronic shouldn't be too hard at all since people already have base maps to load into the unit to start the engine on and work from.

And as I have said before, I will be doing a lot of driving and travelling with this truck so I want to make everything as reliable as possible. This Adaptronic ECU is constantly monitoring changes while driving so I'm counting on this thing to tune itself while I'm going from the desert to the snow :lol: . I can't wait to try it.

Now I'm troubleshooting spark. I have the e420c all hooked up and I'm just not getting spark for some reason. It seems really simple to select the type of engine ignition that the Adaptronic will control. I just need to find out the weak link in the system. Here are the points I need to start checking:

  • I assume the Adaptronic ECU is giving the ignitors signal but I could check those.
  • Double check the ignitor wiring.
  • Double check camshaft angle sensor wiring to Adaptronic.
  • I checked the ignitors and coils have constant + power.
  • Check the distributors? They are brand new.
I've also found that the cause of a lot of people's ignition problems has been the weak wires that lead to the crank angle sensor. These wires are in a pretty harsh environment down under the engine near the main pulley and they have been known to crack and deteriorate to the point at which the car will lose power at certain RPMs. This problem has been solved more than once by replacing and protecting the wires that go to the crank angle sensor.
