Light show guage tuning
Well I can't sleep and I thought of this question while trying to fall asleep,
I'm hopefully going to install the final parts next week, but I'm curious as how to tune. I'm running TE2 and all I have to go by now is the air/fuel guage. i know it's ---- but until I can get a wideband I need to know how rich I should go. How rich should I run it, all the way so the last rich light is lit, or somewhere inbetween. What is the aproximate range for the air/fuel guage, 15-13? it's the automter if that makes any difference. |
Re:Light show guage tuning
Well, I would guess that if your at the last rich light, you won't really know how rich it really is, so go to the second to the last rich. That would make you rich, but not too rich. (One would assume) ;)

Re:Light show guage tuning
In boost, you want your a/fs in the 12s, which means beyond the limits of the autometer guage, or your stock o2 sensor. I"m not sure, but when a/f start to go beyond the limit of the guage it shuts off, this graph shows you the limits of your narrow band o2 sensor http://www.plxdevices.com/M-Series-C...utputGraph.jpg
it maxs out at about 14.2:1, so it's useless for tunning while in boost. I know a EGT guage can help you with tuning, they can be had for relitively cheap. |

I have both the NB 'light show' and my WB hooked up.

Re:Light show guage tuning
Doesn't exactly peg at 14.2, it does show change from 14 to 12 but nonlinear and without precision, depends on the sensor temperature and other parameters.

I nver knew that :o

Re:Light show guage tuning
So How exactly should I tune it, mabye have it rich so that it bogs, and then slowly take fuel away until it starts running correctly? THis would probably be VERY rich right.

Re:Light show guage tuning
either buy a wide band, borrow one, or go to a dyno, with skill and understand you could tune by just fucming around with it and with a EGT, but don't waste your time, sell your virginity if you have to.

Re:Light show guage tuning
no offense but if you are asking the question about whether you should tune with a narrowband, i think your best bet would be, sell the narrowband to a ricer, try blackdelsol and spend the money on rolling road tuning

Re:Light show guage tuning
I see where this is going, I am just asking for ball park tuning now, I plan on getting a wideband in a month or so, this is just to make sure I'm straight for the time being, I guess I'll just take someone elses maps and richen them up a bit.
