Dave Kumar Posted June 24, 2007 Report Share Posted June 24, 2007 Hi guys, I have just purchased a Link LEM3 with adaptor for my V3 STI. Just wanted to know if its possible to interface an innovate LM-1 air fuel ratio meter to the ECU? Thanks Quote Link to comment Share on other sites More sharing options...
ashesman Posted June 24, 2007 Report Share Posted June 24, 2007 Yup, wire the analog output of Innovate controller to An Volt 2 on the G3 ECU. Set up the appropriate voltage scaling in the controller and ECU.... Wire to the An Volt 2 wire between the ECU and adapter or solder to the An Volt 2 pad inside the adapter...

ANDY C Posted June 26, 2007 Report Share Posted June 26, 2007 Also i wouldn't use the standard subaru 02 narrow band for CLL as they aren't accurate enough , use the narrow band channel from your LM-1 and splice it into the loom before the adapter link..

ashesman Posted June 26, 2007 Report Share Posted June 26, 2007 I would tend to disagree, narrow band sensors are extremely accurate for 14.7:1 CLL dithering. They provide a large output change for a small variation of AFR from 14.7:1 (hence the name narrow band). However they cant be used for CLL with a cat converter in front of them (as is the case in some Subaru's). For general tuning and accurate AFR over the entire range then a wide band sensor is definitely the go.

ANDY C Posted June 27, 2007 Report Share Posted June 27, 2007 I'm just going off personal experience and i've been through 2 of them and now the 2nd is inaccurate compared to the wide band. CLL would target and AFR of 14.3 then using the narrowband channel from the LC-1 it was spot on 14.7. I'm not an isolated incident with 02 sensors failing in classic shape subaru's.I and others believe it's the location of them being just after the turbo, also it's probably why Subaru have moved them mor downsteam in the newer models.
