ATTENTION TURBO GURUS!!!

[BOOST69]

Just purchased an 07 apex with MCXpress turbo. Heading to revy. in a couple days and just ran the thing around the yard a few times to test it out. Was ok for the first few times, but now keeps throwing a code. If its outside and cold, sometimes, it wont fire up great and code 23 is up. I get it running and take it out and it runs alright. Bring it in the shop shut it down, fire it back up and its fine. Take her out again and its ok for run, then throws 23 again. One time I noticed it wouldn't throw it if you just putted around, but as soon as it builds some boost, it throws it. It wont idle on its own if the code is flashing. It also threw 14 a couple times, but not as often. I saw a chart and 23 is supposed to do with the atmospheric pressure sensor, 14 is air intake pressure sensor. It's intermiditant which kind of worries me ( after all I also own a 900 polaris!) Anybody got any ideas?? Would be muchly appreciated. I dont want to have a bad start with this thing as I hear the ranting and raving about them. Thanks for the time guys!! MJ

I have seen code 14 on several turbo sleds and traced them all back to a poor connection where we tap into the Intake pressure sensor to power the fuel controller. Not familiar with where MCX gets there signals however.

How is your atmospheric sensor connected and installed?

Please take your time filling in your location in your profile, site requirements There may be guys close to you who may help you out on your error code issues.

I know you have to take the sensor itself out of the air box and install it back into the wiring harness. This will make that error go away. ( I had to do this with my S/C)

I just zip tied it to the harness down along the delta box.


And yes, please do fill in your location...Thanks.
