Davidv Posted December 5, 2015 Report Share Posted December 5, 2015 (edited) There is a basemap already available for Altezza, if you look in the "Base maps" sub directory of PClink.I'm assuming you've got a wideband installed.It should be enough to get you going, by loading that map and then tweaking the "master fuel" value up and down until it runs about right. Only really good until you can get it to a tuner though.What ECU specifically are you using?If you've got custom wired inputs and outputs, no one's going to be able to just give you a file that works. There's a fair bit of time in the configuration.where abouts are you located? Edited December 5, 2015 by Davidv Quote Link to comment Share on other sites More sharing options...
Joseph Yong Posted December 6, 2015 Author Report Share Posted December 6, 2015 Thanks for the info David, I am using altezza G4+ plug in. I am located at Malaysia. Quote Link to comment Share on other sites More sharing options...
Davidv Posted December 6, 2015 Report Share Posted December 6, 2015 Okay, then you should be able to get most of the way there by adjusting master fuel value...And make sure you enter the deadtime for your injectors if you know it. Quote Link to comment Share on other sites More sharing options...
Joseph Yong Posted December 6, 2015 Author Report Share Posted December 6, 2015 Hi Davidv, is it OK for me to replace the original narrow band o2 sensor with the wideband o2 sensor for permanent. Quote Link to comment Share on other sites More sharing options...
Davidv Posted December 6, 2015 Report Share Posted December 6, 2015 (edited) Absolutely, thats what I do... it helps with fuel economy when you've got the wideband set to be constantly trimming the fuel when cruising.Do you already have a wideband kit for it? A few things to keep in mind...1. Generally speaking the wideband needs to be mounted further downstream than a narrowband sensor, and it's very important that you have it mounted at the correct "depth". As in, the tip of the sensor should not be protruding into the exhaust stream at all like a narrowband does.Generally they come with a bung that you weld into your exhaust, read the instructions for correct mounting location and position. 2. Most widebands come with a Bosch sensor, there are two variants the 4.2 and 4.9 sensor. The 4.9 sensor has a better lifespan due to some design changes, I've used the 4.2 sensor and it now needs replacing after... less than a year.So now I'm paying for the slightly more expensive 4.9 sensor on top of the original kit, the poor man pays twice!The Bosch 4.9 sensor is used in lots of OEM cars and if mounted correctly etc is supposed to last 100,000kms if I recall.Going to a wideband is definitely a great idea, not just for trimming fuel while cruising but it gives you invaluable information in your datalogs, if you ever go to the racetrack or whatever. If the car starts running rough you can quite quickly tell that either fuel is a problem, or it isnt.

Joseph Yong Posted December 8, 2015 Author Report Share Posted December 8, 2015 May I know how to wired the 6 pins bosch wideband LSU49 o2 sensor to the Altezza plugin ECU? Quote Link to comment Share on other sites More sharing options...
Simon Posted December 8, 2015 Report Share Posted December 8, 2015 You need an external controller that will then convert the signal to a 0-5V signal. This is then wired in to a suitable AN volt input on the ECU.You are not able to connect the sensor directly. Quote Link to comment Share on other sites More sharing options...
Grant Baker Posted June 5, 2017 Report Share Posted June 5, 2017 Out of interest... How did you get on with tuning this?I'm just doing one now - wondering how the base map supplied worked out with regards to VVT operation and the turbo...? Did you alter the VVT settings much?
