I recently installed a RRM SRI on my 04' Lancer Ralli. I liked the way it sounds and I was impressed with the throttle response. So I drive it to work the next day and about thrity miles to meet up with some friends. When I leave to go home I notice that the check engine light came on, I was pissed!!! So I call RRM asked them what the problem might be. They told me to go over install and make sure everything is tight and that the MAS is plugged in. Then I asked if I need to disconnect the battery to reset the ECU and they said that could be the problem too. So when I got home thats what I did, no check engine light after driving 100 miles. I recall that a few people on this forum had said that you do not need to reset the ECU when you install an intake. Well, this proves that is not the case and from now on when I do any kind of install I am going to disconnect the negative battery cable.

 

its good to reset the ecu after doing anything that modifies any major sensor readings. lots of things are based off of them...

 

yeah, I kind of figured that had to be done. I have done it before in the past with all of the hondas that I have had. I never reset the ecu with those vehicles. Then again I had to reset the ecu with my SRT4. Oh well, live and learn.

 

I installed my rrm sri, I never disconnected the battery cable.

 

You don't have to. It just takes the ECU a little longer to change over to the new air

 

I thought is unplug the positive (power=red color) cable to reset ? I am confusing I am not sure which battery cable should I disconnect to reset the ecu now? Positive (red) or negative (black)? or doesn't matter?

 

It's safer to disconnect the negative battery. You don't have to disconnect both of them.

 

It's always safer to stay away from the positive whenever possible. Remember red = hot like fire.

 

Just curious what made you change from the SRT4 to the RA.

 

The reason I switched from the SRT to the Ralli is that the quality of the SRT was not very good. Yeah it is a very quick car, yeah it is turbo, but as far as long term reliablity is concerned I dont feel that it was there. Like I had stated before in this thread the A/C went out, an axle was going out, the driverside seat was starting to rip. I had a lot of problems with the Dodge dealer blowing smoke up my @ss. All these problem happened under 20000mi. I have to face the fact that Japan has surpassed US automobile craftsmanship and reliability.

 

yeah i was also looking at the srt4, but something about the fact of 18psi on a dodge motor just turned me off... i mean dont get me wrong, dodge builds good autos... but they are not exactly known for their turbos

 

the turbo is the only good part on the srt (it's the small mitsu 16g) but the dodge is made in mexico (like the jetta & sentra) & people have had problems with reliability. the people in mexico are getting paid pennies an hour to build cars. just like the ford escort in the late 80's was actually built in south africa & those people got paid .67 cents /hour!!! for comparison, an american car plant worker averages $22.00-46.00/hour.
