Anyone tried one of these (link @ bottom) to give a narrowband signal from a wideband Lambda. I have an AEM wideband kit and it will not allow me to have a narrowband signal and have wideband signal at the same time it's either one or the other :crap:. Typical I can't fault the AEM kit at all other than this lack of additional analogue output's were as the Innvoate LC-1 will allow you to do this.
Basically my car once warm has an idle afr of 10.8-11.1:cry: and sometimes get's so rich bloody thing dies. On cold start she sit's nicely @ 14.7- 15.0 and I believe when you first start the car this is open loop and relys on engine Coolant Temp Sensor (CTS) and Air Intake Sensor (AIS) once slightly warm after only about 10sec's it switches to lambda then relies on the OE lambda sensor. As I am not using the OE lambda and I really don't want to have to take the F7p turbo downpipe off to get another bung welded on as it's a pain in the arse to fit the downpipe back on I am going to use the attached link and T into the wideband signal wire and use it to give my ECU it's 0-1v feed it needs (0v is lean & 1v is rich) so I can still monitor my afr's, basically I have no feed at present as no OE lambda plugged in so 0v so ECU is throwing loads of fuel to richen it up:crap:
Unfortunatly you can't just take the signal feed from the wideband and plug it in as the signal's are very different.
