    I installed my AEM cold air intake today, then after I got the yellow check engine light I realized that I installed the MAF backwards (not the connector)! After I turn the MAF around the yellow caution light with exclamation point went away, except now the check engine light is still light up. Does anyone know how to clear the yellow check engine light?

    Much appreciated!

    Regards,
    Systemlord.

    You would have to use one of the code readers that has that capability. If that was the only problem, I think you can go through several start/stop cycles and may have to drive it some and the code will eventually clear out of the short term and clear itself.

    I believe it is 7 start stop cycles where the car reaches proper temps and a certain number of miles are added. I could be wrong on the details.

    You were both correct, this morning I went out to warm up my MCS and after it reached operating temperature the yellow engine light disappeared. When I was driving last night with the yellow check engine lit up it seemed as if when accelerating that I lost that low-end torque. I also noticed before my drive that I was unable to get the engine to woosh when stepping on the gas aggressively (to 3000rpm) at idle, did the yellow check engine light put my Mini into a decreased performance mode?

    :cornut: Just my $.02. Get a ScanGauge II and you can read and cancel codes and have 4 real time gauges of your choice. ~$150. Plugs right into the OBDII and takes at least 5min to install.:Thumbsup:

    Do I risk damaging my ECU? Can I have the ScanGauge II connect to my iPhone to display the gauges? Boost gauge, coolant temp and HP gauge would be nice!

    :cornut: No Sir! no damage to anything. ANY data that comes/goes through the ECU can be displayed even while you're driving. 4 gauges of your coice can be displayed that give real time info. Several examples are: Coolant temp, air intake temp(post inter cooler), amperage or voltage, Manifold Absolute Pressure(MAP) or you can adjust the gauge to give Boost pressure(I just do it by mentally subtracting 14.7/15 from the MAP). Get one, you won't be disappointed.:Thumbsup: IPhone- you'll have to ask one of our other fine MINIacs.
