Is this normal ?

[F3600]

Hey i was wondering .. like i said before in some other post: i switched my ECU for a o2 sensor enabled one ( my old harness and ecu is from UK.. they were running without o2) ... its been almost one month... and my new ECU isnt running any fail code (my 02 sensor is not connected) ... im checking it every week and the code 55 show up . Normaly i would be happy, but im kinda worried ..

anyway my car is running so nice ... no breakdown in 4 months!I just need some guts to connect this damn o2 and my new fuel pump wohooo

are you sure its an o2 enabled ecu? if the car is running fine and thinks its running fine, i wouldnt worry about it.

the o2 sensor and fuel pump are really easy and might take you an hour total to install. make sure you have an o2 sensor socket thing though, as its damn near impossible to do otherwise.

Im pretty sure its a 02 enabled one... Yep the car is running fine. kinda tough on fuel consumption... anyway its pull hard and my power output on my multicheker is about 150 PS at stock boost (WHP) and about 175 PS at 0.8 bar

i would say that youre good to roll! you cant touch my car on fuel consumption (4-6mpg) so i think youre fine there too. it sounds wierd but it doesnt seem that anything is wrong. i really wouldnt worry about it.

oh, and your car is def. making more power than mine was. i put down 151whp and 164lb/ft at 10psi. 125whp w/ a 6:1 a/f ratio, 151 at 10psi with a 7.5-8:1 a/f ratio since i was using more fuel with more boost...
