Hello Everyone,

Just ordered a Trinity from Speedlogix and I wanted to know if there was any recommendations either before or after hooking it up to the car that I should do. I've read a few issues from people saying that you should update the tuner before hooking it up and some say that its ready to use right out of the box. Besides that is there anything else or what do you suggestion.

My car is a 2013 SRT 300 all stock.

Any help would be appreciated.

Yes, plug it into your computer, go to the Diablosport website, then update it per the instructions there.

Then you can load the tune of your choice.

This is probably a dumb question but these tunes from diablosport website free? When I called Speedlogix about the tracking number and I asked them about certain tunes and they said that they would charge me $125 for a tune.

For right now all I want is something to bring out a little more power even though the car is stock as well as put something on there that is similar to a "valet tune". Reason for that is because the car will be shipped overseas and im not to fond of random people driving my car yet alone someone I know.

The "updates" are operating files and crom file updates for the programmer, not tunes for your car. The tunes Diablosport develops are already on the programmer and ready to load on your car.

Custom tunes are ones that you can get via email from individual tuners, such as Johan at Diablosport, or built as part of a tuning session on a dyno by a Diablosport trained CMR tune technician.

The attachment will give you an idea of what a crom file update to a handheld tuner consists of.

So the trinity came in and I loaded the 91 octane tune on the car. We only have 91 here where im at.

Now I planned on getting the 180 thermostat next but I had a few questions.

Is the 180 the way to go with a daily drive that is driven in texas where its 95+? I've heard a few thing about a "fan mod" which from what I read it can be done on the trinity by just changing the temps that the fans come on. I've also read that if the fans stay on they can eventually ruin the motors on the fans. Is this true?

Any news on this on which thermo to go with and also what setting for the fan for everyday driving in hot weather? Will this need to be adjusted in the winter if the car is driven so the motor can warm to operational temp to not throw a code or do any other damage?

Just trying to do the basic stuff to the 2 Gen SRT to get the most power I can. I am a newb when it comes to tuning.

A 180 deg thermostat will open earlier than the stock 203 deg tstat. Given that spec, you can take advantage of the lowered coolant temperature and modify your fan settings to help the engine run cooler. It kind of defeats the purpose to set the fan temps at 195 but your stock tstat doesn't open until 203 degrees.

Your concern regarding the life of the fans is well founded. Setting them too low means they will be running all the time, shortening their life. Finding the right settings can be a bit of an experiment, however, look at it like this. Determine where you want your engine temperature to be in a couple of situations, such as low speed cruising and stop and go in high ambient temperature.

I would think you are seeing 217 or higher in stop and go with 95+ degree weather there, right? Let's say you don't want the engine coolant temp to rise past 205 in stop and go. That's a good spot to set the high speed (HS) fan.

The LS fan is normally set at a lower temperature (it's originally programmed to come on at a lower temperature) so when you are slow speed cruising, where would you like that temp to be? 195 might be a good spot. Spend some time looking at the temps you see now to establish a stock baseline.

A high speed cruise really won't mean coolant temps much above the tstat opening temp because you are getting maximum air out there on the highway. If it's really hot you might see 5 - 7 degrees above the tstat setting but not enough to turn on your low speed fan if it's set at 195.

Those are the temps I have mine set at after 2 or 3 settings to see how they worked in day to day traffic.

MADDOG I appreciate the help.

I'll take a look at the temps what they run at stock here with the temps so high.

Is it pretty easy to adjust the fans with the trinity? I haven't messed with it much besides loading the 91 octane tune.

I am a newb with tuning but am I able to adjust the fans while running the 91 tune? Is there a how-to to do this properly? Don't really want to mess up anything if you know what I mean.

Glad to help. You may want to call Diablosport to verify the menu to get to the tune adjust portion of the InTune program.

Just monitor the temps in your normal driving and also, if you can, a freeway run at highway speed in hot weather.

You can adjust the fans running the 91 tune. Take a look at the link below, go to post #7 and scroll down to 9) MODIFY TUNE

http://www.300cforums.com/forums/tu...es/96284-predator-knowledge-base-how-tos.html

Ok guys so I left work today and down here in Texas the temps were reading 100 degrees. Yes very hot...so I saw on high driving it was fluctuating from 203 to 205. The little stop and go that I had to do before reach my house it was running around 207 I believe. Im pretty sure I saw a 208 on there.

All the temps were based off of having the AC going and reading off of the digital gauges the SRT's have on them.

Is that a pretty good basis for fan settings or should I hit the road again and monitor more?

At those freeway speeds I would expect you'd be around 195 or so. What are your fans set at now?
Everything on the car is stock except having the 91 tune from the trinity. I can take a look at it tomorrow and see what the temps are again.

When you are ready, try these settings:

LS all conditions 199 degrees
MS all conditions 199 degrees
HS all conditions 205 degrees

Then listen for the fans and watch the temps. I suspect they will go down but what I would worry about is that the LS fan may run all the time in your hot, hot Texas summer...and you don't want that.

The thermostat is installed, right?

No sir the thermostat is not installed. I wanted to find out what things need to be set at before arrives.
