cobb ap 1 cel question

Mydadssti · 06-11-2008, 03:47 PM

My sti was reading that it is too lean. wat does that mean?

ninjaboy76 · 06-11-2008, 04:45 PM

What mods do you have? What was the engine code? To lean means that it not reading enough fuel with an 02 sensor. The air to fuel ratio is not correct.

right now i have a fmic, tbe, intake, m boost controller and cobb ap stage 2.
Dont i need to change my fuel pump to get rid of the code. It read PO171.

The FMIC isn't helping on the stock turbo.

The intake is throwing the code though. Get a protune or drop the intake.

cn07ob · 06-11-2008, 05:20 PM

my intake doesn't throw a cell. He needs a protune with a fmic. Can't use ots map with his mods.

ninjaboy76 · 06-11-2008, 05:34 PM

Ummm yea, those mods wont work with a Cobb stage two map. Why are you using a MBC? The Cobb maps use the stock boost solenoid to control boost. You aren't suppose to use a MBC. The FMIC isn't helping either. The intake might not be that bad, it just depends on which one you are using.

+1 for protune, and you should get rid of the boost controller

Mydadssti · 06-12-2008, 01:32 PM

But my MBC is always all the way down. I dont really need much boost. I just keep it there in case i run with my nephews. SO its a protune that i need to get?

ninjaboy76 · 06-12-2008, 01:43 PM

It doesn't matter if you have your MBC set all the way down. The Cobb maps are not setup for ANY aftermarket boost controllers. They are setup so that boost is controlled by the stock boost solenoid which is controlled by the ecu. You will continue to have problems until you decide to get a protune for your aftermarket mods that are beyond the limits of stage 2.
