TurboBrett Posted April 27, 2008 Share Posted April 27, 2008 i have an Afr gauge i bought for tuning the mini but never made it onto that, I'm going to fit it to the supra, am i OK to take the signal from the diagnostic port wiring or is it best to take it from the sensor loom (by the turbo's), will do step by step pics aswell if i remember, cheers, brett Link to comment Share on other sites More sharing options...
Ian C Posted April 28, 2008 Share Posted April 28, 2008 If it's a narrowband gauge, take it from the door light or the clock or the throttle position sensor for all it'll help you monitor the car But the diagnostic port Ox pin will indeed give you the narrowband voltage. Just don't use it to tune the car as "rich" on a narrowband can be 13.5:1 which is "Lean" when you are on boost. -Ian Link to comment Share on other sites More sharing options...
TurboBrett Posted April 28, 2008 Author Share Posted April 28, 2008 yes it is a narrow band, and its all fitted i pulled the sensor signal from the ecu loom, i dont intend on tuning the car with it, just some cool lights too look at;) i did successfull tune the mini on narrow band, i got the needle profile almost spot on through a trial and error method, then took it to a rolling road to have it tweeked under load SU carbs are so simple when you understand the basics, ecu's are not simple for me:( Link to comment Share on other sites More sharing options...
