mestew87 Posted June 19, 2012 Share Posted June 19, 2012 I am just finishing the single turbo conversion on my soarer and was wondering about the factory lamda sensor, The factory loom is very short on it due to the location of the factory downpipe, however with the top mount kit the sensor will not reach, So i was wondering what people with the single turbo conversions have done ? I have also fitted a full standalone ecu system (AEM EMS V2), would i be able to utilise a wideband lamda in its place instead ? Quote Link to comment Share on other sites More sharing options...
mellonman Posted June 19, 2012 Share Posted June 19, 2012 i think your ecu can be mapped to have a closed loop map where it trys to maintain 14.7 afr, what i have done is just extended the wires to the stock lambda to keep my closed loop as i have a large turbo T67 which doent make enogh boost while still in closed loop to be a issue and have a AEM FIC 8, cheap piggy back ecu Quote Link to comment Share on other sites More sharing options...
mestew87 Posted June 19, 2012 Author Share Posted June 19, 2012 I was thinking about just cutting and extending but wasnt sure if the extension would affect the voltage figure from the lamda, I have went down the Holset HX35 route Quote Link to comment Share on other sites More sharing options...
mellonman Posted June 19, 2012 Share Posted June 19, 2012 its best to extend the wire on the sensor not the loom, im not 100% if it has an affect as i have fitted a n/a sensor on a TT car due to the TT having a flange on the sensor, but after the car is hot and left for a couple of minutes it will stay lean when started for about 20 seconds but a cople of blips of the throttle sort it out.

Swampy442 Posted June 19, 2012 Share Posted June 19, 2012 Yeah just extend the loom on the O2 probe, job done. Quote Link to comment Share on other sites More sharing options...
little num Posted June 19, 2012 Share Posted June 19, 2012 Hello mestew87, is your ECU plug and play or has it been hard wired in, im also single but still on stock ecu but looking to change in the very near future to get the most of of the car, also what injectors have you fitted and have you had it mapped at all.

mestew87 Posted June 19, 2012 Author Share Posted June 19, 2012 The ecu was a plug and play unit but it had a custom harness made for it to be plug and play, the car is still on the standard injectors for the running in of the clutch etc, I have a set of 550cc injectors, so should hopefully provide enough fuel for 500bhp I bought my e u and harness from drift motion! There's one for sale just now for £800 with the patch harness I bought the same turbo you are running Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted June 20, 2012 Share Posted June 20, 2012 James this is a stonking deal from a mate of mine, much better option than old skool emanages http://www.driftworks.com/forum/parts-sale-private-sales/178336-fs-aem-ems-2-soarer-1jz-harness.html Quote Link to comment Share on other sites More sharing options...
