K&N Typhoon CAI (Bad gas mileage)
Hello all.
I recently purchased an K&N Typhoon CAI and got it installed. The sound is deeper, engine sounds smoother and pickup seems a bit quicker. The main reason for this post is to understand why my gas guage is giving me readings as if I am driving like a madman when I havent changed my driving habbits since I got the CAI installed. Before I got the CAI installed my gas gauage would show mid to high twenties when on the highway and now when on the highway I am getting like high teens to low twentiesw (17-20). Do you think its because of the cold weather or maybe my ECU needs to be reset. I really dont know. Any advance would be helpful. Thanks in advance.

I believe I found out what the problem is with my gas guage. I was driving to work today and it looks to be my gas guage is behind or slow estamating my gas mileage. For example it might take 5 mins for it to change from when I was on a local street speed avg then I would switch to highway speeds and it will think I am still driving on a local street. For example I would be on the freeway for 10 mins and the gas guage would show avg speed at 25mph and avg gas would be 17mpg but I would be on the freeway driving at 65mpg and the mpg should be around 20+ ? Make any sense? The ECU is confused?!?

The gas mileage indicator is a running AVERAGE. If you understand what that means, then you would know that what you see is perfectly normal. Reset you mileage indicator immediately before you want to get a reading under the present conditions so that the earlier average does not contribute to your readings. I doubt you gauge is 'wrong'. And the cold weather has a lot more to do with your gas mileage than the CAI.
