so i installed my innovate wideband this weekend. the sensor was programed with clean oxygen as the instructions stated and placed just after the down pipe on the 1,3,5 bank. while the car is at temp and idle the gauge reads 10.3 which i understand to be rich. i turn my fuel pressure down to 20psi and it does not lean out. while stepping on the accel it continues to get rich. not sure if this is a problem in my wideband, ecu or some where else. im running a walbro 255 with 555rc injectors on factory rails. not sure where to go from here.

 

First Off.. Congratualtions on getting the Wideband.. You can learn a lot about what the Car is doing by watching it..

1) What is the AFR Dispaly?.. Gauge ( What type and what does it read.. voltage/Data Stream ).. are you reading with a PC?.. Have you?..

2) Before you start the Car ( After a Prolonged shut Down ) does the Dispaly go to 20.9 after the gauge warms up?

3) When you Decelerate, and the ECU does a Fuel Cut, Does the Dispaly go to +20?..

4) Depending upon what gauge you are using, is the LC-1 Set to output Lamda rather then AFR?..

Cap

 

its reading direct threw the LC-1 gauge display, yet to hook it up to my pc. while the sensor is heating up it is at 7.7 until the car is fired. havent taken the car in the road as I fear im washing the cylinders. took the ecu out of the car and does not appear to have a chip so i believe that it is just dumping fuel due to the 555's. im going to look into gettting nistune but no 1 seems to have a type 2 board f/s. thanks!
