Best wideband location for this setup?
347 LM7 forged shortblock
Milled/ported 243 heads
DELPHI 42lb injectors
Torquer v4
TSP long tube headers
102mm TB/Short runner intake
340lph Holley Sniper drop in fuel pump
4l60e
Stock ECU
Stock harnesses
Ngk plugs/coils
Holley Waterpump
Alternator with slightly higher output can’t remember exact numbers rn
Big 3 wire upgrade
Has AC
So my main question like I said is what is the best setup for the o2 sensors to go? And where would I put the wideband sensors? Front or rears? And I believe you can delete one or the other? Of course deleting the AIR and EGR, and aiming for no check engine light obviously and an accurate AFR reading. Will probably go with the AEM sensor and gauge.
Next, with the build basically being just a slightly stronger version of the ls1 that came out originally, the stock harness and ECU will be fine for tuning this correct? I’m going to have my tuner send a start up tune and then take it to him for a dyno. And if I decide to get a new gauge cluster and want my Map, Maf, water temp and fuel pressure etc. would I need new sensors and to make another small fuse/relay box for those just so I don’t have to fk with the stock fuse box? Haven’t had much experience with this side of automotive work so any advice would be greatly appreciated! If you need more info just ask
For the WB02, put it in either side, less than 10 inches from the collector, in the 9-12-3 clock posistion, anything in the top half of the tube.
If you put in the lower part, it can prematurally kill the sensor
