Highest Value for Stage 4 Map

Big-Sexy907 · 01-28-2006, 12:40 PM

Whats your highest value for your stage 4 fuel map (vf34, 30 etc)? I'd even be interested to know what your average values are.

Thanks all!

Sorry, I'll be a little more specific.

I'm using STI pinks and have a high fuel value of 8.8 with a average fuel value of 7.9 or so. Does this coincide with other people who are running a stage 4 car with a vf turbo and supporting mods?

What is your scaling set to? What firmware are you running?
Your fuel map will differ from someone elses if your scaling is not the same. Even if your scaling is the same it will differ depending on who tuned it.

^^^^^
I know that was not very helpful.
But there are so many variables with your question that it is almost unanswerable. Every car is different, every tune is different, and every tuner is different. That is why people pay hundreds sometimes thousands of dollars for a custom tune.

No worries, Let me see if I can recall. Injectors are scaled to 550, with 4.6 firmware I believe. I'm just looking for several general answers to see if I'm on the correct path. I'm currently boosting the VF34 to 18psi with Egts around 1400F or so. I have been reading that I can increase EGTs up to 1500 or so, but I'm hesitant due to the cold weather here in Alaska.

I have been suffering from a bit of boost spike, due to the cold air temps. I'm curious to know if I can increase my fueling and decrease my boost values to compensate for the problem.

First post up a log from logger1.
If you have a WBO2 it would be easier ffor us to sugest changes to your mapping.

Be careful using egt only as it can be affected by the ignition timing as well as the fuel. I wouldn't play too much with the fuel without a wideband- they can be had for well under $300 these days and will help save your engine.
