Timing / Fuel question

[jfsrt4]

Ok Hes a question I have been looking for a answer for. Timing and fuel is a big deal when it comes to power so, heres two setups would one be more powerful because it will be giving more timing.These are not real both say 20 psi boost.

1. Say 40psi on the fuel regulator clamped at 4.2V making a 12.0 air fuel ratio
2 35psi on fuel reg. clamped at 4.7V making a 12.0 air fuel ratio.

Would one be stronger than the other. I am wondering this because I just got a dtec and withh be now using it for fuel control instead of my mapclamp. What do you guys think...

More timing does not mean more power. Ignition timing needs to be such that peak cylinder pressure occurs somewhere around 15 degrees after TDC. To figure what timing you need to achive that you need either really expensive test equipment or put it on the dyno

The least amount of ignition advance that produces the most torque is usually what you want.

^^^this is correct, and with that being said, try for a clamp around 4.6 volts, this usually produces the best timing, and then adjust the fp to such that at the 4.6 volts you have the a/f you want

How would I go about tuning for Voltage with the dtec. I am new to it. To you guys know where theres like a how to for the dtec on tuning it. I get a little confused on tuning at different throttle %s

The dash display on the Dtec shows voltage out. Taking the car for test runs would be the way to see where you're at.
