Hi guys well like the title said I'm running rich. Like 11.9 at idle and 12.3 at cruseing speeds(I get 34 mixed mpg). I have a chipped p28 with a unknown chip. Here in the next few months I'll be going with the Neptune setup but for know I just need a new chip. Dose any one know of some one to burn chips for cheap?
Re: Hooked up a wide band and running stupid rich.
You can't run a wideband with a P28 no matter how much you "chip it".. You need a proper engine management system if you want to use a wideband. A wideband is a lot different from a narrow band than most would know.
