Stillen A/F

[fxlr8]

I would love to get rid of the 7th injector and box. I sometimes worry the box isn't working... I ran the car with the cipher connected yesterday and just hitting around 6.5 psi boost my a/f was around 11.6..

Does this seem right? or is 11.6 lean?

11.6 is getting close to lean.

You're better off raising fuel pressure via the JWT FMU, than relying on the fuel tap the Stillen set up uses. http://www.my350z.com/forum/showthread.php?t=351173&highlight=fmu

I just emailed a rep at stillen.

Thank you for your inquiry!

That is just about perfect. We want between 11.2-11.7 on stage 4 to be safe.
The maximum boost (8psi) is at around 6500 rpm. Some cars will vary abit,
and headers, high flow cats etc will affect boost.

Hope that helps!

Looks like I am around the norm according to Stillen.

Getting pretty close to 12 to me, with possible heatsoak of the blown air the chances of pinging get higher and higher.

I probably need to test again hitting max boost at 8psi and compare again the a/f. What parameters should I log on cipher viet? I wish cipher could log boost.

I wish it could too.

I usually do the af ratios (have you entered the ecu mode yet?) coolant temps, intake temps, maf voltage, throttle position, vehicle speed, turbine revolutions, vehicle speed, and a few others depending on what I'm working on.
