Can anyone tell me whether this module just increases fuel pressure or does it also change timing and duration?

 

The one I have(EZD1000D) is fuel pressure only, no timing or duration. I think all Edge EZs are fuel pressure only.

 

I think its fuel and map. but the question i have is how much do i need to worry about egt's with this box cranked all the way? i dont have a gauge yet

 

You are right about what it does! But you NEED gauges if you are going to run it on any level, just more so on the higher levels. These trucks can hit the max EGT's stock and go WAY over with the box.

 

I dont really tow with it and when i stick it its only for couple seconds wide open

 

You dont need gauges with an EZ unless you are towing.
Hotrodding around town with an EZ does not warrant gauges.

 

Ok, yes the MAP connection is used. I assume this is the monitor/fool boost for the extra fuel pressure. I have not tried the EZ by itself on a stock setup. I did have a DR Performance 85hp fuel/boost pressure box that on sustained WOT would push EGTs over 1500* empty. Did not have that box for long.

 

Thanks for the replies. Iwas wondering if I could Use the EZD1000D with a Bullydog power pup downloader?

 

The answer is yes, the results are subjective. I certainly would not do this without full gauges.

 

I think I read once that there is actually some timing change as a by-product of the pressure increase.

 

Well I suppose timing could be affected by fuel pressure and boost fooling, but not by changing the ECM timing and duration programmed maps. The EZ does not have link to the ECM to do that with.

 

You are correct ........ I said as a by-product.

 

Thanx for helping me out, I'll use all of your suggestions.
