Ok, so I had a fuel leak from my fuel tap for the n2o. It was leaking for close to a week (yea yea, I know). Anyway, I got it fixed. Well from what people have told me, my car is running rich as hell.

The reason I ask this here, I have the utec and have been learning to do my own tuning (mad props to the guys that can, this stuff is nuts!). Anyway, I haven't changed anything utec wise for the fuel, so I am thinking that the ECU upped the fuel flow in response to the leak? Is this a valid assumption? Should I reset the ECU? Is it worth it? Or should I be looking for something else. Maybe I should wait and just put in the wideband and get a better idea?

I was running fine before the leak, so im not sure what the deal is. Any advice would be greatly appreciated!

 

my theory is this, unless the fuel leak was major, more than a few drops every second or two. you shouldnt have any problem with the computer altering the fuel injectors. its a returnless fuel system so it just constantly flows fuel into the rail and the injectors use a little of it as needed.

i think you should be fine...

 

Even if your ECU did sense that leak, and up fuel pressure changing A/F's, your UTEC @ WOT overrides EVERYTHING the ECU is doing-meaning whatever A/F maps yor running is what your getting....

Your best bet and best investment as far as tuning A/F will be to get that WB, datalog and go from there.

 

Yea, I think your right Bert. Just a bit frustrated cause I haven't adjusted any of the A/F ratios. So the UTEC is doing something naughty I think. Also, Tony mentioned that he could smell my exhaust really bad on the way up. Im headed home right now to A) do an oil change (cause I hit the miles driving home) and B) see if I can get some tuning done. Maybe hit up my friend and try and get the WB put in (if hes home I can use his welder).

Thanks for the info guys!
