predator questions

o.k. i installed the 93 CAI tune, anything else i should do? I did set the tire size for the tire we have on for the winter, i still have to reset the TCM. should i lower the fan on speed since the t-stat is now 180 degrees? if so what should i lower it too. any thing else?

Good ?. Someone will answer soon.

you can leave the fan alone...

tstat will open on its own...

and fan will kick on when needed...



can maybe adjust shift points... slightly...

turn off speed regulator, well turn it UP...

turn the fan about 20 deg lower than stock across the board. i think i have mine at 185LS/190MS/195HS not 100% sure thats what i have mine at but it sounds right.

john says to change fan setting, chris says no...hmmm what to do

if you dont adjust the fans you will still see high coolant temps near how it is stock. no point to putting in the low thermo if you are gonna see those temps anyways. just because the thermo opens lower doesn mean the fluids wont get hot. you have to cool the fluids themselves too. otherwise you wouldn't even have fans.

I also have mine set at what Jon has his at.

ahh, i see. is there a noticable difference in your heat now?

also what are the speeds you refer too? mph? if so what is low speed, med and high

raise your top speed limiter to what ever it says in your gauge cluster ( just cause you can), reset tcm adaption, firm up the shift points!

when you go to adjust your fans you will see it.

there is a low speed fan for light cooling, medium speed fan for medium cooling, and high speed (the one you hear outside the car)

im not sure if the r/t has the 3 stage fans or not but it still has the 3 settings in the predator menu for them.

you will notice there are 2 fan menus one for with AC on, and one for with AC off (air conditioning). you need to set them to the same settings in both modes.

big difference. in stock form i saw up to about 215-220 on the guage in autostick. now it never gets over 197 or so.

i mean like your heater heat.

i don't want to tear up the car so, what should i raise my shift points to and what firmness?

no change it works the same as before.

No, heat still blows hot. The car will run cooler though.

good input guys!

to recap fans at 185, 190, 195 for ac on and off, top speed to somethin' higher (i'll match the speedo) reset tcm, firm up shift points, and shift firmness.

the user manual says the shift points are a set value so i'll go with that (obviously)

and the manual says the shift firmness is also a preset value.

cool, thanks


and jon this is from the user manual for the fans

Fan control:
AC off high MPH high speed fan on temp so i want 195
AC off high MPH low speed fan on temp 185
AC off high MPH medium speed fan on temp 190
AC off low MPH high speed fan on temp 195
AC off low MPH low speed fan on temp 185
AC off low MPH medium speed fan on temp 190
AC on high speed fan on temp 195
AC on medium speed fan on temp 190
AC on low speed fan on temp 185

right for the fans?


thanks guys

You want to drop everything about 20 degrees from the stock settings.

thanks guys

are these the stock fan settings?

cool thanks

im looking at buying one soon, isnt their preset tunes or is this something ill also have to do

ghost no.. i copied the adjustable paramaters from the predator user manual and put the temps next to the setting to see if what i tryped in is what i should use.

jesse, there are preset tunes, these are quick adjustments in addition to the preset tunes, i'm still trying to tweak what i got.

Don't forget to make a backup copy of your stock tune. The Predator will automatically back it up for you and store it in the Predator but if something happens to the Predator, you risk losing the copy. Mine came with a USB cable (not sure if I had to pay extra for that - maybe) and there's a program called DSDownloader you use (download that from the Diablo site) to back it up to your pc. I reset mine to stock every time I take the car to the dealer just to be safe.
