I'm merely suggesting don't go wild with ford speed density.

One of the games played when converting to MAF is to trick the wiring on the 02 sensors and just use 1. The primary advantage for dual 02 sensors is that the computer can regulate the fuel flow for each bank of cylinders dependent on the 02 readings from that bank's 02 sensor. There is no capability for a SD system to accept dual 02 sensors.

Mustang speed density computers used two O2 sensors, and the truck MAF computers (EEC-IV only) used a single O2 sensor, so associating one system to how many O2 sensors it uses doesn't always hold true...

Waiting patiently
All,
I am planning this exact upgrade once I get back from Afghanistan. I have a '90 F350 Crew Cab 460 / E4OD 4X4 I want to convert to Mass Air. Almost all the previous posts are concerning 302s and 351s. I don't exactly feel like spending $2,045.95 from Mass-Air.com. Everyone is talking aout how easy this is but I have yet to see a step-by-step for the 460. If you do, can you please enlighten me?

Being picky
All,
I have noticed massairsystems.com (PMAS) has a kit but it is temporarily discontinued. It was only $1,382.00, still high but cheaper then Mass-Air.com's $2K+. I know it sounds like being picky, but at the same time I am doing all of this, I might as well get one that converts my batch (bank) fire to sequential fire also. Might as well get some fuel economy while I am at it. WMS Racing has a pretty good kit that is better than Mass Air but it doesn't say whether or not it is also sequential. I have an email in to them to find out. Does anyone know of a system that won't cost an arm and a leg that is Mass-Air (or equivalent like WMS Racing) AND sequential fire? Thanks.

"Also be sure to include info on the E4OD guys"
I agree!! The e40d has been my biggest problem in trying to convert to MAF. I'm still not sure whether i'm supposed to have 8 or 9 wires on a 92 e40d/5.0.
