Ballyhannon Posted April 6, 2014 Share Posted April 6, 2014 Folks I need advice. I am running a 1.5 Paseo engine using i think an ECU from 1.3 EP91 (89661-10181. 211000-6571). I did not do the engine change. It seems to run Ok just feel it is short of power. Would there be any difference in the two units. And if so what is the part code for the Paseo unit.

Ballyhannon Posted April 6, 2014 Author Share Posted April 6, 2014 What I am asking is if I fit a 1.5 ecu to my 1.5 engine will it perform better than the 1.3 ecu it is currently running on. Quote Link to post Share on other sites
