ECM Question

[95sanger]

Hi All,
Does the V/8 ECM have to be reprogrammed for this swap for best performance? I would like to delete PATS and have unit set for my 33" tires and 410 axle ratio and set for 92 Octane (while staying smog legal of course!). My truck seemed to loose performance with the 4.0 when I changed the gears from 373 to the 410's (possibly the ECM thinks it still has 373's?). I found Ron Francis will do this, but can't find anyone in the Central Valley that can do this locally (most guys that tune are doing imports or GM only).

Any Help Or Suggestions Appreciated,

Mike

Mike, a lot of guys just get a SCT and so it themselves. I do know of a guy out in Colorado that does it for $200+. He can change all the perameters you want.

What EEC?
The Ranger it's going into?
And the donor engine & any mods you plan for it?

If you are interested in DIY tuning, here's a good link I wrote up to read over just to know if it's something you want to get into:
