The change between 94 and 95 is the TCC changed to a PWM version which had much heavier Kevlar IIRC clutches for more slippage and smoother operation and of course programming in the PCM bin file.
Hey EagleMark
How do I find out the rear/front ratio of a bin file if it isn't in the description? my truck has 3.73 gear ratios
After several hours of combing through my current 1994 bin file I came upon this "TCC PWM 1995 Only" and checked the SET box so now I won't need to rewrite my bin to accomodate my 1995 4L60E right?
Gear ratios in descriptions are just notes someone has added in. There's nothing in this particular PCM that has anything to do with axle ratios. I've found very little to no difference in how the tune is changed because of axle ratios... so don't worry...
Cool thanks for that I was worried about using the wrong ratio.
Well i"ve used the idle tables to really bring down the idle in park I'm at 700 in D I'm at 600 awesome!!
Now how do I get my Tach in the dash to read the same as the tach in TunerPro? it's about 500 rpm to fast since i switched from v6 to v8.
Yeah it might be a electro-mechanical thing (like a resistor change) because the tach is definitely still off by at least 500 rpm the redline goes OVER 5000 rpm and the shift points don't seem right unless I'm completely nursing it and when TunerPro says I'm at 600 rpm my tach says more like 1100 rpm
Oh no! another question!!!
I put in a 180 deg thermostat stock is 195 deg I don't want it running that hot are there any changes I'll need to make in the software to compensate?
All the aftermarket tachs I have seen have a switch on the back for 4, 6, or 8 cyl engines. They simply count the number of times the coil discharges in a set ammount of time and use that to display rpm.
Not knowing how the factory chevy tach is set up, I do not know if the curent one could be modded to work, or if it would need swapped out for a V8 one. I'm sure a little google searching could find you the answer.

Do-it yourself articles, the problem is, different years use different capacitor values.
