Installed the mac cai kit and flashed computor with the predator tuner. The car runs great, but I now have and engine light on. What did I do wrong and how do I correct it. Any suggestions .

 

1. Check your MAF senor and wire

2. Are you using a tune made for the MAC CAI? If not you need to get a custom tune to get the a/f mixture correct. Your car is probably running lean.

3. do a search on this forum on CEL (check engine light) as there is a lot of info available.



Good Luck!
PS - if you need a custom tune try Brent at DTP. He probably could do a tune for the MAC (I think) through email for you. PM me if you need his info.

Use your Predator diagnostics mode and find out what the trouble code is. That will point you in the right direction when you call for assistance.

 

For those of you with MMR MAF, 5% fuel increase with extreme SCT Xcal tune finally turned my CEL off.... PHEW

 

what you did wrong is buy a mac product... i dont like there stuff , terrible fit , quality , and everything else that can go wrong .... but thats just my opinon

 

You can contact Brent at DTP Racing if you need a better tune. I understand that a recent customer with a MAC intake was very pleased...

 

Sorry for the lack of an answer. Have you tried re-flashing the computer yet? Sometimes this works well. Also, remove the sensor and check that there is nothing impeding the seal, in the sensor itself and also check the fitment on both the filter housing to the MAF and the screws on the sensor.

 

I had Brent make me a tune for Mac...and car runs great!

 

Mac needs a custom tune!
