Is the AEM not reading any input signal when cranking? Looking at the dizzy plug (ie from wire side) with the plug latch at the top the 24tooth pick up is the far right, sync is second in from left, ecu sensor ground far left if you need it. Double check your using the right inputs. They're not hall effect sensors EDIT: What sort of filtering does the AEM have if any?

No worries!

Looks like the hard line from the turbo actuator up to the high/low boost solinoid - wont cause your issue How much boost are you running? 12 is usually a signal issue from the dizzy to ecu

Quite often its the idle control assembly under the throttle body - give it a good clean out or even bypass it to see if there is any change

Yeah thats a speed sensor error code - pretty weird to get thou. Sure its 42 thats coming up?

I'd start by continuity checking between your intercept wires and the dizzy plug, make sure they're going to the right pins. I don't have the aem software but can you check its registering rpm when cranking? It may need the cam sync - most aftermarket ecu's I setup do need it

Ah, its only a plug in. Just downloaded the software and manual, clunky... Yes use NE and NE- for crank pickup (reluctor/mag) Use G for cam sync (reluctor/mag)

Loose connection in the fuse box?

They connect to various things - injectors and the ecu are the main ones. The earths to the ecu are called power earths which carry load current, the ecu then supplies sensors earth to the sensors which it monitors for interference against the power earths which is why its critical that important sensors like the map sensor and water temp sensor are connected to the sensor earth from the ecu and not direct to the head.

I assume you are wiring in an aftermarket ecu? There is a 24tooth wheel and a sync wheel (two syncs) inside the distributor below the rotor which tells the ecu the engine position. They are reluctor type triggers. NE is the 24tooth trigger usually TRIG#1, G2 is the sync usually TRIG#2 (Note, depends on which ecu you are wiring in), don't normally need the second sync. Looking at the distributor plug from wire side), Trig#1 is the far right, TRIG#2 is second one in from left, far left is ground to ecu SIGNAL EARTH not main earths. IGT is the output from the ecu to trigger the ignitor (spark event output). IGF is a feedback from the ignitor to the stock ecu to confirm there has been a spark event - if there isn't any feedback the ecu will show a fault code. This isn't usually required for aftermarket ecu's. STA tells the ecu the engine is cranking which enriches the main injectors for cold start essentially.

NE and G- are 24tooth and sync respectively

One of the issues with the 3s fitment is how low you have to mount the engine which in turn upsets shaft angle and how much you can feasibly lower the car. Yep best to stick with an e series box. Believe one of the camry boxes is physically the smallest and helps fitment

Did you get any water in the diagnostic plug? Can cause issues.

Interesting but my thought is that the stock ecu is still supplying the ignition spark event and it calculates engine position via the 24tooth and sync trigger inputs from the dizzy. The emanage only adjusts the duration of this +/- for each pulse. Think about a stand alone ecu, not IGF signal is needed. Thoughts? EDIT: By the way, the IGF wire may not be shown on the pin out diagram but always check the actual pin IDs by taking the cover off the ecu - they're printed on the board.

Definitely clutch type - you can shim them so they drive/lockup as you want them to suit your intended use ie street/track/strip

Poor earths is usually the fault for the clock - as above, rip it out, clean it all up and re tension the pins in the plugs so the grip tightly.

Take a close look at all of the pins and connectors to the emanage - sometimes they can become loose especially as these are often second hand units that have been through a few vehicles. I've had this with a few ecu's I've setup and found the connection works for starters but after a drive/vibration they can cause issues. Have you tried turning off the ignition map and seeing if this makes any difference (ie ignition from the stock ecu runs un-adjusted) - you could also try to zero the ignition table and see if that makes any difference. This would rule out a software or config issue. With the ignition harness I take it your only using one channel in and out? Its been a while since I've worked with an emanage but you could possibly try swapping to another ignition channel? I've just opened the software but need an ecu connected to get to the full config - you might be able to stipulate which ignition channel your using. The stock ignitor which I assume you are using is termed a 'dumb ignitor' with dwell controlled by the ecu - so you can run this without an IGF signal. IGF just tells the ecu that there has been a spark event - on a 4efte ecu if no IGF signal is recieved after a certain number of IGT events it will throw a fault code thinking the ignitor is faulty. It doesn't serve any other purpose. I would assume the 4efe ecu being a more basic setup would just not utilize this feature. Not sure if you have an oscilliscope or not - you could check that the output waves from first the stock ecu so you can see the waveform pattern then from the emanage (with zero tables) to make sure the wave forms are the same shape/frequency. You could rig a drill onto the dizzy to test this without having to crank the engine over for long periods. Lastly, the rotary switch settings - essentially the 4efte ingition system uses the same VAST system as the 4age does - and the 4age rotary settings are 2,4,2 but as you say, you've had this running so I doubt any of the jumpers or rotary switch settings are at fault.

Sorry, TK test. Its the technical name for the "sniffer" test. Shows if their is any combustion gasses in the coolant. Could also pressure test the coolant system and see if its leaking back into the cylinders. You do get moisture out of the exhaust on start up/warm up - its condensation from cold exhaust/hot gases, but this should go after a good drive as the whole exhaust system should get pretty warm.
