Default Crank Trigger Pattern & Other questions

Hello
I didn't want to spam the forum with multiple threads and I know for a fact that this wont be the first or last thread I'll make now that I am at the final stages of my build.

Quite techy questions...
  1. Would anyone know what the crank trigger wheel pattern is for an IS250 2011? Auto, if that makes any difference. I need this to trick the Lexus ECU.
  2. I no longer have the neutral safety switch - is there a way to trick the IS250 into thinking its in neutral without buying an NSS? I know SC300s and older gen IS200/300s can..

Thanks

See pictures:





Part2:
I'm guessing new engine to this car will not be using the engine control ecu is that correct? If it IS, Permanently engaged in neutral will throw codes once it starts moving.

Some details on the actual plane perhaps? It sounds like you need a black box to mimic a bunch of missing inputs.

Hello mate,

Just had a look, looks like 32-2, thanks! Somewhere we found info online suggesting it was 36-2

No, so new engine has a standalone but we are trying to wire the original 'push to start' button to work with new engine. We have a trigger wire ready to wire up.
The codes isn't the issue, we need to and want to understand if the neutral safety switch is stopping it from cranking from the button.

Thanks!

So this was an automatic I'll assume but honestly it doesn't matter. Pull up the schematic and look. I mean, if you're this deep, you must have that, yes?

Appreciate the help buddy, thank you.
Basically, the information isn't free and is a nightmare getting ahold of here in the UK.
We've got everything working now with a lot of help from some US buddies.

Now back to the trigger pattern for rpm.
