I have a 2008 Evo X and I recently installed a wideband gauge because of a problem with the injectors either staying on or just spraying to much gas after a rev. I found out that on cruise I'm running way lean like around 18-19. I checked for boost leaks and there is none. Would that mean there is a leak somewhere before the wideband gauge? because, I have done multiple pulls and have put about 20k miles on it before putting the gauge in and it hasent blown yet. I have evoscan and I don't get any knock and fuel trims are good. It still confusing me why it takes so long for the revs to come down after a rev? BTW im more of dsmlink guy so im not very formiliar with evoscan..


ADDONS... AMS intake, AMS intercooler, AMS piping, AMS widemouth 02 housing.

 

What are you using to log your afr's? If you're showing 18-19 at cruise I would be assuming an incorrectly calibrated wideband or incorrect calculation formula before boost leaks or the like, especially if trims are good and there is no knock

 

I'm using an autometer pro-street, I think that's the name. They told me that it doesn't need to be calibrated.

 

Have you checked the fuel relay in the fuse box under the hood?

 

no what exactly would I be looking for?
