lim327.ap2 Posted March 18 Report Share Posted March 18 Hello Everyone, New here, but this is my second time around a linkecu, and starting to love the practicality of stand alones! Anyway, I'm starting to use the G4x Plug in for my 04 ap2 s2000 F22C(non E throttle), and my main concern is, would the G4X NEED/strongly advised to keep the OEM narrow band? along with the post cat O2 sensor? if not, then I can I remove those from the exhaust, and leave the chassis connectors for those unplugged. In the pinout, it shows c1 and c16 for the "NB O2 Sensor" but I am just not sure what that really means... O2 sensor for me means the post cat efficiency sensor. Not the narrow band. And since I'm not running a catalytic converter as a track car, I wouldn't need the O2 sensor either. I assume the tuner can just disable the OEM wideband and O2 sensor. Also FYI, I will be using the Link CAN Lambda for wideband. Ideally if I can get confirmation that I can uninstall the OEM narrow band and o2 sensor, then I can install the LSU4.9 into the bung that was once the narrowband. Thanks for the help!

Confused Posted March 18 Report Share Posted March 18 The Narrowband sensor is practically useless. Ditch it, replace it with the Link CAN Lambda module, or if you happen to have another wideband controller that isn't junk, you can utilise this analogue input for it's wideband 0-5v output.

Yeah I get the narrowband can basically only sense stoich, Just wasn't sure if it was a needed sensor for the Plug-in G4x   7 minutes ago, Vaughan said: No need to keep the factory NB O2 sensors sounds good, ill remove both the NB and the post cat O2 sensor, and only run the CAN wideband Thanks for such a quick response!

lim327.ap2 Posted March 25 Author Report Share Posted March 25 Didn't want to start a new thread, but related to the pins and wideband, would anyone know if the CAN1, CAN2 ports of the ecu be enough to support the Can Lambda in regards of amps? I figured if I can keep the DTM connector to itself into the JST, rather than branching out power and ground, it would alot cleaner. TIA!

Vaughan Posted March 25 Report Share Posted March 25 The 4 pin JST CAN headers were designed with CAN Lambdas in mind and so should be able to supply enough power for them. Note you may still need the 22uF capacitor if you have heating issues. Quote Link to comment Share on other sites More sharing options...
lim327.ap2 Posted March 25 Author Report Share Posted March 25 Okay, just making sure, cause I've read in the past that the JST 4 headers were only 3amps continuous, and 6amps only for 30seconds... but when in the market of buying the can lambda, it seemed like it was all plug n play with DTM to JST4 and then in the instructions its saying preferred to a 10amp fuse ignition power separate, and that it calls for 8amps.

Vaughan Posted March 25 Report Share Posted March 25 I have used a Link CAN Lambda with the JST 4 pin plug on newer plugins and it has worked fine. lim327.ap2 1 Quote Link to comment Share on other sites More sharing options...
