87 Turbo, E6K, wired up following the diagrams from k2rd.

First, I have only one trailing plug firing. T1 has no spark at all, nothing coming from the coil, T2 is firing fine. It has power going to it, I swapped coils, spark plugs, and plug wires and it still is not firing. Dont know what else to look at.

Second, whenever I am coming off idle, the car stumbles and wants to die. The idle drops and the wideband reads very lean, over 16. If I give it gas slowly, it will be fine, but if I give it a quick rev, it stumbles. I dont know what to do about this, I am thinking its something with my throttle cable, but I'm unsure.

Has it been tuned?

What are your ignition settings?
What is the tooth offset and offset angle?

The THROTTLE PUMP map needs to be adjusted.

If you are using stock FC coils did you enable to the toggle feature and wire the Aux. Out as your toggle select? In the K2RD diagrams it clearly tells you about the Toggle.

If you didnt do that its never going to fire, and if you're running without a trailing you might want to fix that first before you run it.

I tuned it. I started with one of the base maps from this section. I just tuned the fuel maps, low 14s in vacuum and low 11s and high 10s in boost. I havent messed with the timing at all.

I'll check tomorrow all of those settings.

I havent messed with the throttle pump map, so I'll try that tomorrow.

I am using the stock fc coils. I'll have to check tomorrow to see about the toggle feature.
Kinda already put 700 miles on it without the trailing plug.

Yikes

If you are using one of my maps from the base map thread and it said it was for stock FC coils, then the wiring is specific to that setup, where you use Ign2 for Trailing signal, and the Aux. Out (green/black) wire to the "toggle select" wire on the trailing igniter, if you dont wire that up then the coil just fires on one side only.

The Aux out wasnt set to toggle. I guess I never set that when I loaded the map originally. Thanks Claudio.

I have another question. I can rev the engine and the tps still reads 0%, is this a problem with the tps or the throttle cable? I already recalibrated the tps several times and it still is the same. Also, when I have fuel-cut on decel enabled, it cuts fuel if I rev the engine, like a rev limiter, and also when I'm driving with light throttle. Right now I have it disabled.
