I've heard a lot of different A/F numbers being thrown around, should I stay in the high 11's above boost, for a pressure of 10psi. and what about 14psi????

Another question: I do have a Datalogit and a wideband. To those who have tuned their cars w/ a wideband, what types of runs should I start with? 3rd or 4th gear, slow or WOT? Where should I start adjusting first, should I start with fuel.. say, the 3000rpm band and move up, should I just log a 1/4 mile WOT run?? I figure I'd start with adjusting A/F at idle and then 0-3000rpm w/ no boost, then finish the 3k-7500rpm under boost? And then adjust my timing, or visa versa?? All help is greatly appreciated!

 

Does anyone have any expertise in the matter??

 

I'm sorry I have no experience yet with tuning but I'm curious about your setup. I have the datalogit and I'm waiting for my motor to get rebuilt and my single kit to be completed. I'm going to be using the DIY WB O2 sensor. Which O2 sensor are you using and how is it working out?

 

I purchased the FJO wideband, I haven't had enough time to mess with it yet. I'll be sure to let you know how things go. I guess I'll figure things out on my own about the tuning and from the SEARCH menu. Everything is pretty much self explanitory on the Datalogit. I just read through the manual a few times and messed around w/ settings a few minutes a night on the laptop, it all makes sense after while. I just thought someone could shine some light on the subject, maybe a few pointers.

 

I thought you would watn the a/f ratio to be the same wheather its for 10PSI or 14PSI because its a ratio. true?

 

Might try posting this in the ECU forum too...lots of folks there with aftermarket ECUs and lots of expertise too.
