I've fitted a 20V 4AGE in my AE86 so now I've got to get it running using VEMS. I'm close to have the diagram for the harness done but I'm not quite sure how to run the trigger.

I would like to use the sensors in the distributer. It's got three sensors:

I'll try making it work with the 24+1 setup first. If this fails I'll go 36-1.

//PhatBob - the Toyota trigger is terribly noisy and you'll have to do a lot of messing with the triggering circuits to even come close. We use these:

You should be able to get it work on 24+1 (eg. 1.1.27 firmware), it's by far the most frequently used from the InputTrigger/MultiToothNoneMissing family. Just beware of polarity if VR (or the edge if HALL - iirc it is VR) and measure signal DC bias when connected to VR trigger input and ignition on (and take note).

Someone chose hw swap and installed 36-1 on a 16V (maybe it was before 2007, or he just likes the more precise timing from crank? If wheel is made in smallworkshop, 12-1 cranktooth with HALL sensor recommended):

===================================

Or talk to Gintsk, scroll down and you'll see:

Toyota AE 86. GT25 bb turbo. Fully sequencial on stock 24+1 VR sensors. Active COPs from VAG driven from stepper chip. For drift.

GintsK?: I use 24 and 4 distributor with 3 teeth cutted. So it is 24+1 setup. I checked polarity only for camsync signal. Polarity was right.

JanPedersen?: I've decided to try this out but I'm not quite sure how to set it up.

Anyway smarter is to use disc on crankshaft. It is more precise and no need for readjusting after any mechanical manipulation on engine.

But. Your 36-1 probably will not work because of two reasons:

---

I can't get the trigger to work. I know that the distributor generates a signal, the wires are ok, so that leaves the vems. I followed Peters guide: http://www.au2stereo.dk/vems_installation.pdf

I tried to test the the primary trigger using a 9v battery but still nothing. Any suggestions? Any common problems on the vems board?

FAULT FOUND!

Next problem: No matter how I set it up I get a steady 1500 rpm while cranking which seems quite high. I tried using a single trigger setup to se if that canged anything but I stil got 1500 rpm using a 24 teeth and the program set up to four?!? Then I changed the program to 24 teeth and still no change... WTF!

---

I was told to try another firmware to get my trigger to work. But which one should I go for? 1.1.27 but I can only find it in two beta versions, that I can't get to work. They load allright but trigger isn't working no matter how I try to set it up...

So if someone could guide me to a good firmware and a working config - just to test the triggersetup - i would really appriciate it! At this point I'm getting quite frustrated

How can I set this up?

A: For secondary trigger (cam pulse) VEMS use two separate inputs (different connector pins) for Hall and VR sensors.

So it is not a problem. GintsK?

Secundary trigger is now working. Seems quite good as it pics up quite small signals. It calculates the engine speed to a steady 250 rpm while cranking. But now it fires quite crazy, not 180 degrees apart like you would think. Pattern looks like this:

Its the same pattern every time so I don't think its due to a noisy trigger.

I was told to use firmware 1.1.27 as it supports N+1, so I tried that first. But its stated that N<=11 so this wouldn't work I guess. I then tried 1.0.73, 1.1.18, 1.1.41 and 1.1.44. None of these altered the result. Anybody has a running car using 24+1? If so which firmware?!? And I would love to se your config and tables! Anyways this is my config and tables - does this look right:
