Lets play a game...Guess the Gears!

[backwoods]

alright i toasted a pcm on my car a couple weeks ago ive been retuning my car using ford IDS my door tags reads SE or 3.27 limited slip that is not right when going 70 mph the speedo reads 84-5 to make my guessing game easier so i dont have to continue to reprogram my pcm until i get it right lol maybe state your ratio and rpms ats certain speeds and ill try and match it
thanks guys

Sounds like you may have 4.10's I have 4.30's, in 4th gear at 60mph im sitting at about 3300-3400 rpms with t45 transmission

Looks like you are probably either 3.90 or 4.10

(85/70)*3.27=3.97

Since 4.10 is much more common than 3.90, I'd go with that

Why guess? Jack the rear end of the car up, mark the driveshaft back by the pumpkin, turn the rear wheel one rotation and count the driveshaft revolutions.

Slightly less than 4 revolutions, 3.90s, slightly more than 4 = 4.10s.

you can put your info in this calculator until you get a chance to jack up your car and verify....worked perfectly for me...

Gear Ratio Calc

That's because the IDs can't program any strategic codes older then 2005 anymore without consent from ford

Where do you get that info just curious and I work at a ford shop so how would I go about getting consent?

As do i you need to email ford give them the vin number and a reason to why your doing what your doing and they will let you open it up.

On the ids does it let you do any strategy reprogramming for your vehicle?

The process takes a few weeks.

It did when I rewrote the new PCM but it allows me to input the wanted specs states it rewrites and checks then continues to read out at original inputed gear ratio (off aproximatly +15 Mph at 70 mph)
