Sold my turbo kit and want to get the car back to stock injectors.

Currently have a P28 running on uberdata (BBKA map)

Can I install one of those “performance” Ebay chips (I have a couple kicking around) in place of my uberdata chip?

The reason why is that I don’t have anyone to burn me a stock map but I do have a couple of those chips from ebay.

 

sure why not

 

or cut j1

 

I heard something about that before, what exactly does that do?

 

then you are driving with the stock ecu map

 

So even though the map that’s on the chip for boost, cutting J1 will make it so it only reads the factory part of the map and allow me to run my stock injectors again?

Sounds to easy.

 

J1 makes ecu stock again if cut. Jump it it goes back to eprom

 

Ok, so I will not have to get another chip with a stock map? I can still use the chip that’s already in there with BBKA map?

Thanks

 

Can someone post a pic of J1?

i went ahead and googled J1 for you and found this
