Hey guys just got a freshly built motor in the car running aem ems v2

Build is as follows:

H22a wiseco piston upgraded pins 8.5:1 darton dry flanged sleeves k1 rods
Arp rod bolts
Aem ems v2
Running 2 egts and 2 widebands
K-series coils and aem epm

Now the car is running good and egts are fairly close to the norm on e85.
What we are having issues with is making sure 110% our timing is synced perfectly.

I'm just curious to hear some of your guys tips or tricks of doing this, we were originally doing it by hooking up to a coil and shooting off the cam gears but not sure how close this is getting us.

Thoughts and opinions are really needed on this.

 

Get yourself a coil wire were it is easy too hook up on the spark plug tip, then attach the other end to the coil, then hook up your timing light pick up to the wire. ensure that you disable your injectors by unplugging them ( easiest route) or disabling them in the software. Then manually (in the ems) set your timing to 16 Deg to get a good base. Have a buddy crank it over while you watch your mark to ensure that your aiming for that 16 degree mark so that way your physically matching the timing and syncing it with the ems. Keep in mind that you will have to have you or your buddy advance or retard the timing until you line up at the 16 degree mark. Its been a while since i done this but this is what i briefly remember. Good luck .

 

If you want your timing to be accurate, find cylinder 1 TDC and set a pointer at your crank pulley mark. There are too many variables to do it any other way..

 

What exactly do you mean by pointer. With it being a h series factory went off the flywheel and unfortunately my twin disc doesn't have any marks on the flywheel.

 

After finding true TDC take a piece of wire like a coat hanger or welding rod and attach it somewhere on the oil pump and bend it to where the TDC mark on the pulley is.

 

So, put it on TDC, then mark the flywheel inline with the pointer on the block. Use a retarding timing light set to 16°.
