ECM is used to make the target (the 'jammed ship') lose all its current target locks. The jammed ship cannot target anyone for the duration of the ECM module's cycle (20 seconds), and will have to re-acquire its targets afterwards.

ECM success is chance-based and all-or-nothing. For example: if your module has an adjusted strength of 4 and the ship you are trying to jam has a sensor strength of 20, then your chance of success (20%) is lower than if you target a ship with a sensor strength of 12 (33%). If the module succeeds in jamming, the full effect will always be produced. If it fails, you have to wait 20 seconds before you can try again with that module. Note that you always have some chance of success.

The Caldari race has ships that get bonuses for using ECM modules.

The tech 1 ships that have bonuses for ECM are: '''Griffin''', '''Blackbird''' and '''Scorpion'''.

The tech 1 ships that have bonuses for ECM are the '''Griffin''' (frigate), '''Blackbird''' (cruiser), and '''Scorpion''' (battleship). The tech 2 ships are the '''Kitsune''', (Electronic Attack Ship), '''Rook''' (Combat Recon Ship), '''Falcon''' (Force Recon Ship), '''Widow''' (Black Ops).

Note that, due to the low base strength of even the most powerful modules, these bonuses are, in practice, necessary to get any useful effect from ECM. '''In other words, if you're fitting ECM on a ship without ECM bonuses, you're probably making a horrible mistake'''.

There are 5 types of ECM modules: 4 racial jammers and a multispectral module.

The racial jammers each have an increased sensor strength against 1 specific race ~~(i.e., Caldari)~~. The multispectral jammer has an equal (but lower than the racial) strength against all races.

The racial jammers each have an increased sensor jam strength against their specific race listed below. The multispectral jammer has an equal (but lower than the racial) strength against all races.

The 5 types are:

Note that using multispectrum jammers is ~~a waste~~. They have way less range, use more capacitor and have less jam strength in general. If you have time and you know the race you are going to go up against, refit to jam that race specifically. If you're not sure, fit a mix of all racial types.

Note that using multispectrum jammers over racial jammers is not so advisable. They have way less range, use more capacitor and have less jam strength in general. If you have time and you know the race you are going to go up against, refit to jam that race specifically. If you're not sure, fit a mix of all racial types. However, multispectral jammers should not be disregarded completely. They are useful as backup jammers on specialised Ewar ships when facing enemies of unknown race. Excluding the griffin, all Caldari ECM ships have 5 or more midslots, 4 of which should be accommodated by the racial jammers. The remaining slots can be used to fit multispectral jammers. Using this setup, the ECM ship will identify the enemies ships, attempt to jam with the corresponding jammer. For example, if a blackbird with 4 T1 racial jammers and 2 T1 multispectral jammers is engaging a stabber. The stabber has a base ladar strength of 13. The blackbird activates its ladar ECM against the stabber. This has a 3.45/13 x 100% = 26.54% chance of success with 0 skills, a lack of signal distortion amplifier but including the 15% ECM ship bonus. Say it fails, and the multispectral jammer is activated. On its own, its success is 2.3/13 x 100% = 17.69% chance of success. However, when these two actions are carried out one after the other, the probability of a successful jam is (1-(1-3.45/13)x(1-2.3/13))x100% = 39.54% (2 d.p.). With the 2 multispectrals activated after the racial the chances are (1-(1-3.45/13)x(1-2.3/13)^2)x100% = 50.23% (2 d.p.). This is a nice little bonus, and with the right skills, T2/named modules, signal distortion amplifiers, and ECM complementing rigs the chances are increased. The equation used here is very simple, and can also be found on Evelopedia. P = 1-(1-p)^N, where P is the overall probability of the jam, p the probability of an individual jammer's jamming probability (jammer strength/ship scanner strength), and N the number of the same jammer. For calculating differing jammer probability, use P = 1-(1-p1)x(1-p2)x...x(1-pn).
