too rich

[TheWhiteCB7]

Hey guys. Im running a dsm turbo setup. I havin problems with the AFR as it reads im runnin rich (9.7-9.8) at idle and when running. Can runnig the setup with the dsm 450cc gray top with green tips cause this problem? if so would i have to change to the Blue tops. Please get back to me ASAP. thanks

More often than not cars typically run richer at idle. That's why most people say that idling your car "wastes" gas!

I thought 450s were blue tops??? Check the tune on the ECU and such? Didnt you say you had soem sort of boost leak also in a previous thread?

If your car is doing that then something is wrong. AFR around idle should be around 14.7 which should be atmospheric pressure or whatever. If your rich when your idling something is wrong.

or its tuned slightly rich to give abit of extra protection.

9.7-9.8 isnt a lil rich that is basically billowing black smoke. 14.7 is pretty universal you wont really blow shit up at idle.

i checked for any boost leaks n theres none. im still havin the same problems as i did before. is there a way juss to tune or burn maps for the AFR and only the AFR or do i have to make my own map off the PO6? i really dont want to use the car until i figure the problem out. so please any other suggestions?

holy rich jesus!

anything under 11 is WAY to rich! unless you are boosting at idle, it should be a normal afr. which is around 14.0-14.7.

you're gona wash your rings out like this. lean it the fuck out asap.

do you have a burner? if so, just lean it the fuck out until you start reading 13's.

idle columns are the first few on the left. you can tune with just a wideband and a chip burner.

here's a guide you can go by.

Well... this depends. If you first start your vehicle, and your engine isn't warmed up to operating tempature, when it is idling, the fuel doesn't get completely burned off. It has nothing to do with your AFR settings in the computer, it has everything to do with the mechanical operation of the engine.

Cold Idling = Lousy Combustion = Running "Rich"

[NAiL05]

Cold idling is a diff story. Still 9.8 idling even if its cold is not right at all. The computer adjusts settings according to what the sensors tell it and when your normal idling with the car warmed up you should be around 14-14.7 just like what jose said.

and you seem to know about tunning the pt6. I cant burn the chip in it. but i bet you can!!!!I have a really weird setup and its is just going to be a nightmear to figure out how to tune with out help. I mean shit Im not even turbo and im already running rich according to my afr.
any help would be great and Im sorry for inturpting this thread!

[NAiL05]

Why are you running a pt6 on your setup...Its not tuneable at all. Your better off with a p06 first of all...
