Pyfa Fitting Simulator Walkthrough

The Basics


There are quite a few fitting simulation tools, but Pyfa is by far my favorite. It’s simple, easy to use, but gives you the information you need to accurately fit your ships. [Download here]

Let’s fit out a basic Frigate and get into some of the nuts and bolts of this tool. We’ll go with a Merlin because, well, I love Merlins. (Use this fit at your own risk by the way, I snagged it off another website and have never used it). Once you have Pyfa downloaded and open, copy all the italicized text below (this is called EFT format).

Now, in Pyfa, click Edit, then click From Clipboard. This will load the fit and all it’s stats. Let’s analyze it further. In the middle section, you’ll see this:


iyugPyfa MiddleHere we see all the modules and rigs loaded into our fit. You can click the green checkmarks on the left to toggle individual modules online and offline, and it will change the fit’s stats accordingly. You can also right click your weapon modules and load different ammunition. It lists the modules, organized by high, middle, low slots, then rigs. The following columns are Powergrid, CPU, Capacitor Use, Optimal /Falloff Range, Tracking Speed, Estimated Price, then Ammunition, if any. This is all great information, but the real meat of Pyfa is to the right of this section. It looks like this:

Pyfa Info

The top drop down menu allows you to load your character’s stats and skills into Pyfa for more accurate information. You must first login to Eve through Pyfa to do this. Click CREST on the top toolbar, then Login To Eve. Follow the prompts to load your character. The other option in this drop down menus is All 5. Selecting this option will simulate the fitting as if all your skills were level 5. The next section is the resources box.

Pyfa Resources

This first shows turret hard points, launcher hard points, max active drones, then maximum rig calibration. Below this shows your CPU, powergrid, drone bay capacity, and drone bandwidth. This numbers will change as you tinker with your modules and drones. Now we come to the Resistances box:

The top number is your EHP amount. Clicking the box that says EHP will change this number to Raw Hit Points. The colored table shows your resistances in Electromagnetic, Thermal, Kinetic, and Explosive, organized by Shield, Armor, then Hull. Now we come to recharge rates:

Pyfa Recharge Rates

The first column is passive recharge rate, followed by active shield boost, armor repair amount, then hull repair amount. The rows show the amount recharged or repaired by both reinforced and sustained amounts. Since we’re using an Ancillary Shield Booster with CapĀ  Booster charges, we see 104.6 hp/s in both rows. The next box is Firepower is and relatively straight forward.

Pyfa Firepower

First is weapon DPS, then Drone DPS, and last is both amounts combined. If you click the button to the very right, it will change the values to mining yield amounts. The next two sections are Remote Reps and Capacitor.

Pyfa RR and

The Remote Reps section is especially handy for Logi pilots. It shows how many GJ/s you’ll transfer during a cap chain, then how much shield, armor, and hull you’ll repair per second. In the Capacitor section, the most important number you’re looking at is where it says Stable. This fit is stable at 47% capacitor, meaning with all the modules on, your capacitor will drain to, then hover around, 47%. If your capacitor is not stable, it will say Lasts: (x) minutes, meaning with all your modules on you will have that many minutes of capacitor use. Last but not least is the Targeting and Misc. section.

Pyfa Misc

This section is pretty straight forward, but it still contains some very valuable information. Now if you want to play with these fits or make a new one, you’ll do that from the Market tab on the left.

Here you’ll find every module, drone, rig, etc., currently in the game. Clicking the Fittings tab will allow you to select a new ship to fit or browse your current fittings. Now one of the coolest things about Pyfa is it’s ability to export your fittings straight into Eve. Click File, then Export Fitting, name your fitting whatever you want and save it in Eve’s fitting folder. Now go in game and go to your Fitting Management tab.

In Game Fitting

Click Import, then find the file you saved. This will load your fitting straight into your client.

Pyfa is an awesome tool all around, not just for wormholers. Mess around with it, fit a few ships, and if you have any questions, ask away!

Fly safe,

  1. Hi,

    Thanks for doing this, bit confused by this line though:

    “The rows show the amount recharged or repaired by both reinforced and sustained amounts.”

    What does that actually mean? When would the values be different then?
