Will look at your cal file if you post your own personal most ballerezt soup recipe. I will know if you steal the recipe.

I bought the car with the tune that's on it now. I just downloaded the F/IC software, hopefully I can pull up the one that it's currently running on and post that up. I'm not sure how that tuning stuff works or if I can pull up one that isn't saved on my computer, but I'll do that this weekend when I'm home with the car.

AEM Fuel/Ignition Controller. It's a piggyback system.

then you happen to live under a rock.
AEM makes some awesome products.
The FIC, unfortunately, and when run on a miata, is not one of them.

Just out of curiosity, have you tried to add more fuel in the cells where you are getting lean conditions...? Because if I was seeing lean conditions at X boost and Y-Z RPM, I would just hook that old F/IC into my computer and tell it to put more fuel in that range... problem solved.

The F/iC is perfectly capable on a miata for a setup like this. You still need to understand how to work a fuel map.

I haven't. I bought the car boosted with the current tune on it. I just downloaded the AEM F/IC program, but don't have the cable. Not sure if it's something I can pick up at Best Buy or what. Plus once I do connect it, will I be able to pull up the current tune?

It uses the same USB cable that a USB printer uses. The f/ic is designed so that you can remove it from the car and plug it into a computer, and it will operate by itself(it is powered by the USB port). This means that the tune and everything will be in the F/iC. You are probably going to be confused, but you need to differentiate between vacuum and positive pressure (boost) on your fuel chart. You need to increase fuel in the positive pressure section. Oh you will also have to disconnect the vacuum line going to the f/ic. This might be a good time to make sure that vacuum line isn't crimped anywhere.

Awesome, I'll take this as good news. Why do I have to disconnect the vacuum line?

The only 'recipe' I have is the one that the dyno shop put on and from everything else I've seen from them, I don't know if I really trust them after all. Give me until this weekend and I'll go home and plug it in for you guys.

Check your vacuum tube to the f/ic for kinks.
