Ok, I have the Diablo tuner and want to know for people that have tuners in general. What do you change your shift points to? I want to change mine, but don't know what would be the best. I have an 04 with 5.4. Thanks for any info.

 

Does anyone know?

 

I doubt youll get much in the way of responses for one thats not a very popular tuner here it seems, and second the adjustments are made differently if I remember correctly. On a diablo its a % compared to the edge where its anumber. I could be wrong I havent had a diablo in almost 2 years.

 

I am wanting to change my shift points (what rpm it shifts at). The Diablo tuner has the actual rpm that you change it to. I just don't know what would be good places to shift to get the most performance out of each gear.

 

1>2: 5400 rpm
2>3: 5300 rpm
3>4: 4800 rpm ( torque converter limitation, to prevent ballooning)

If you also have a rev limiter setting, ensure it's set several hundred rpm above the figure above.

Analog tach is a laggardly SOB, BTW, so be advised

Your 1st to 2nd is good @ 5400rpm, and your 2nd to 3rd works well at 5100rpm.

 

I have the Predator tuner(p/n-U7153) in my 2000F-150 w/the 4.6.One of the reasons I purchased it was because of the different shift parameters you have to play w/ in the tuner,and that also is my biggest dissapointment,the shift parameters in the tuner.I've changed all the shift points,shift firmness,torque modulation and My trans.still does not shift like I would like it to.i've read many tech articles and they all basically say the same,that you really cant get the shift you want w/ a tuner,and thats where I'm at w/ mine.Its a good tuner,timing,maf,global spark advance,injectors,rev limiter,o2 sensors,egr and obd can all be changed or modified w/ the tuner.I've purchased a Transgo shift kit to help me w/ my shift problems,apperently thats the best way to go.I personally like the tuner,but if I had to choose again,I would go w/ a Troyer tune or have my truck tuned on a dyno,that truly is a custom tune.I hope this helped,good luck.

 

thanks 4 the info
