So its the ECC that controls the limiter? Its not the Speedo(PSOM?)?
I have the Superlift speed corection box in my truck and it has a switch so you could choose from 2 different tire settings. So say you set on setting to your normal speed and set the other setting to a lot slower speed so when you wanted to go faster than 95 you could switch over to your slower output setting so the PCM thinks your going slower than you actually are. IDK if this would work but someone else might know. Just a thought.
Yeah it gets a parallel input from the VSS.. the PSOM is just for the speedo. And you need to know what the EEC box code is to figure out what tuners or chips are compatable, there is usually a label on the EEC connector with that and you may also be able to get it from the calibration code on the drivers door decal.

That may be true with the 4R70W transmission but he has an E4OD transmission and the PCM computer gets ALL of its speed information from the PSOM.
The E4OD does not have an Output Shaft Speed Sensor like the 4R70W does.
So, it will toss the trans into "fail safe" mode than... I don't know if I would want that, as it shifts REAL hard when that happens. I have a shift kit in there, and got the trans hot once playin in the snow, when it went into fail safe, I thought the dash was going to fly into my lap when it shifted.
