I'm having trouble setting up the ignition in the E6K in my 1990 RX-7 Turbo due to some conflicting information. I bought the Haltech from rx7.com who supplied a map. I installed the CAS according to Matt's (The Hitman) instructions on his website. I was able to get the car started eventually with some throttle and cranking. It ran very roughly. After setting the trigger angle all the way up to 100 and turning the CAS, I was able to get the leading timing mark to line up (with the timing lock on), but it still ran roughly and wouldn't start without some throttle. I went to double check the other ignition settings and the settings from rx7.com and the ones that Matt specifies are very different. Here are rx7.com's settings:

Trigger edge: Falling
Home edge: Falling
Trigger angle: 75
Tooth offset: 1
Spark mode: Distributor
Engine type: Rotary
Aux out: Ign toggle
Constant charge 3.0 ms

They also say to install the CAS with the engine at 90 degrees BTDC so that one of the top teeth are at the trigger point. Now, I know the stock pully only has 2 timing marks nowhere near 90 degrees BTDC, and I don't know of any aftermarket pullies that have otherwise.

Now, after re-installing the CAS and trying both settings, the car won't start at all.

What's the right setup?

Thanks and sorry for the long post.

The trigger edge of falling seems to be the setting when one is using 8509 adapters. If your stock crank sensor is wired straight to the Haltech then you need to select the internal reluctor adapters. The gain setting is usually 2.
Since you are using your stock igniters make sure you ignition output edge is “falling”.
If the output edge on “rising” the leading will look like it is firing correctly at idle but the trailing would be out. You will also end up burning out the igniters.

also one thing to remember is to install the CAS 90* BTDC with the trigger pointing to the pick up. rotate the e-shaft CCW 90* from TDC and install the CAS. should be within 10* after this.

i had similar issues, if you set the CAS up as per Matt's instructions, the tooth offset should be 3, not 1 as per all his base maps.
