I have a S5 91 na vert. Can anyone help me out fixing code 27MOP (General) - Basic Fuel Injection and fixed timing. If i rpm the engine up to 3500rpm the check engine turns on and engine doesn't work quite good.. I've scanned the ECU after that and gave me that code. If i disconnect the OMP and use premixed i can solve the problem, right? thanks!!

 

I don't think you can disconnect omp on s5. It goes straight into limp mode.

 

You would have to replace the MOP to get rid of the code. you cant just disconnect it, the code will still be there.
You can either go to a standalone ecu, or use Rtek ecu stage 2 flash to get rid of the MOP completly.

 

Or just use the omp... But I also have one for sale if you need one.

 

ok So i know that this is an old post, but how much would it be to get a new MOP

 

brand new from mazda? probably $1000+

 

I deleted my MOP...I use a Sham-Wow!

 

I used Kool Kreem

Now my mop is 20% cooler

Looks more like Fluttershy or Skrillex actually.
