2 bungs... What to do with them???

[180crafter]

Hey guys.

Finishing up my SR and I've got 2 bungs I dont know what do do with. One is located on the Greddy J-pipe and the other is on my Downpipe, where the cat is supposed to be (my downpipe is extended so that you dont need to have a Cat).

Now my setup calls for the Power FC, which I am not sure if it uses any signal from the stock O2 sensor, and I've got a EGT gauge from DEFI.

Suggestions please, and thanks in advanced.

If you're talking about the hotpipe on the greddy fmic, that's the bung for the stock recirc. The other bung on that custom DP seems like it would be for a sensor or something? maybe EGT or O2?

egt on the dp would be useless...the one in the j-pipe is for the stock 02 sensor.the powerFC will want to see that. the second one could be for a wideband that you haven't installed yet.or a plug if you're not gonna do that.

Thanks EX. So let me see, you recommend that I use the stock sensor location for the stock sensor, and then use the second bung for custom A/F monitoring.

Then Im guessing mounting the EGT gauge in one of the runners would be best. Thinking the one before the last, if your looking from the front of the car to the back. This cylinder would have the highest temps of all right??
