I hooked up my SMC 500 and now I throw a code 13 which is a barrometric pressure code. I try to reset it by either pulling the ground or pulling the ecu fuse, but it doesnt go away? Any idea what the cause is? My car runs ok but idles wierd, im guessing because its in limp mode from the code? Any help would be appreciated!

 

Did you check to see if your Atmospheric Pressure sensor is bad?

 

How are you using the SMC... are you using it to do an "injector" hack with larger injectors and a limited map voltage? If you are boosting and you're doing your fuel management this way then you haven't trimmed enough voltage from the MAP which is probably why you get that code.

If I'm off base here totally then I apologize...

(One other thing you might check... if the SMC is actually wired in to intercept the MAP voltage, check all your wiring to make sure you're hooking the right ones up in the right places. Also, solder and wrap all your connections.)

 

Code 13 is the barometric pressure sensor, which is built into the ECM, right? MAP (manifold pressure) sensor is code 3...

 

yeah lots of people also get this code when soing the AFC hack...sometimes you cant get rid of it, and sometimes u can...not a problem though
