Speed Density?

[wilderyzed]

Anyone ever tune speed density before? In other words eliminating the MAF and all the bs and tuning fuel and ignition based on RPM and Throttle Position? I think it would be easier to get my big cammed car to run more properly(get rid of the hesitations and such) if I tuned speed density

Are you wanting to switch to a stand alone ECU? As far as I know, there is no way to set up a SD model in any newer MAF based Ford ECUs, but I've only tuned Fords with SCT and TwEECer software. What is your setup, my guess is that you'll be able to get it to work with the stock ECU (unless it's really wild).

This is Alpha-N modeling. Speed density creates a VE model based off of manifold pressure and RPM to calculate desired fuel mass.

speed density cant work with an aggressively cammed car. It works off of vacuum, and an aggressive cam doesn't give off enough


SD sucks, stick with a good MAF setup

tell that to the LSx world :shrug:

You can make it work with a aggressively camed car. But it is difficult to get good drivability compared to a Mass air car.

What software are you using?
