Default Help with AEM Stand-Alone!

Bought it and followed these directions till step #26..

My timing light wont pick up signal from the coil wires. And I pulled a plug out to see if it was getting spark and its not. No ignition signals are being sent out. I also cant smell raw fuel so the injectors aren't squirting either. The "coil/inj" tab in the aem tuner software says that they are all active "on" I've tried multiple times doing all the wizards double checking that things are set up correctly. The car is not "stat syncing" when turning over. How/what can i check to get it to sync up?

I'm curious how many people have tried this out and got their car working? i just want to make sure my car starts with it is all before getting it tuned as I'll have to make a good 3+ hour trip to find someone that knows what they are doing.

ANY HELP IS GREATLY APPRECIATED!

Well if youre using a plug and play you should already have the ign teeth sync set which is what you need a timing light to check. I on the other hand used the EMS-4 and couldnt get the value so I used a timing light to set it. You have to kind of rig a coil pack to give you a short length of HT wire to put a timing light on. You can get a timing light that will pickup off the sig wiring to the coil packs, but theyre pretty expensive, as far as I know the only one Ive heard of that will for sure work is from snap-on at about $300 or so. You can find short HT lead wires in the back of autozone, than just take the rubber boot off the coilpack and electrical tape one end of the HT wire's boot to it so the two inside contacts (springs) make contact than plug the other end onto the plug using long needle nose. Than you can use a regular old induction timing light to check it Ill grab a pic of the one I made here in a few.

I am using the pnp harness I got from dezod with it. When I hook my fic back up my timing light picks it up and works like its supposed to. Or are you talking about something a little different? I mean it works fine and gives me read outs with no issues just using the fic.

If there is no stat sync it wont fire the coils. log your cam and crank sensor (t1, t2) signals and post the datalog.

where exactly are you located?

can you email your calibration to boostworksny@gmail.com please

Off note, this Toyota ECU will start no matter what. Just had a car with a broken off tooth on a crank trigger wheel start and run fine on the factory ECU, yet refused to start on the AEM.

I'm 35 mins east of Syracuse, ny. I will send a log when I get home from work. Do you have any calibrations I should try out that you're willing to share?

After I see your logs and calibration I should be able to steer you in the right direction.
Also you should consider coming down to Xenocron Tuning Solutions once you get everything sorted out for a tune.

Yeah if stat sync isnt on, you wont get sig to the coil packs. When you crank does the stat sync come on? Does your crank and cam count increment up? If you want me to, Id be glad to take a look at your cal for you also. If its AEMTuner I can look at it right now just email it to npound7110@gmail.com - if its an older cal from AEMPro than Ill have to look at it on my tuning notebook tonight.

No calibrations are going to work if its not syncing. I have had the EXACT same symptoms as you. I am trying to help.

I work at Xenocron.

You were absolutely right, didn't make a difference whatsoever. I sent you a couple data logs so you can load them up and see whats going on. Thanks for the help

Got the logs. No cam sensor signal. Emailed a few things to try. Good luck!

That will cause a no stat sync for sure. Email me a copy of said log?

No cam signal at all. Didn't even flinch during cranking. That will cause a no stat sync.

I'm going to double check the cam pin outs on the harness to see if they match up correctly to my ecu. Then I'll be tightening the cam sensor/pin gap to see if that does anything. If that doesn't work then its gotta be the unit correct? Thanks for pointing me in the right direction mike!

I'll have an update hopefully by the end of the weekend

Check those first two things out then we will go from there. What camshafts are you running?

Factory cams. Just looked through the harness. Using the 07 pin outs. Factory pin 26 is connected to pin c29 and factory pin 34 is connected to pin c30 and c9. Is this correct?

E8-26 on the OEM connector should go to C29 on the AEM (CPS +)
E8-34 on the OEM connector should go to C30 on the AEM (CPS -)

Why does it go to C9 as well?
C8 and C9 are for the crank position sensor

You should hook up a voltmeter and test the signal wires at the AEM ECU for connectivity. I would also test the wires while spinning the engine to see if the signal changes when it sees the dowels on the end of the cam.

I would also bench test the sensor itself.
