Got this off Moes (Updated Nov 2009 I think) might clarify some future hope for all set-ups?

*Idle RPM, Rev Limits and Speed Limits available on 04-08 Models for initial release. 03 through future update. Transmission Shift Points 05-08

It was my understanding that it could be adjusted with a custom tune. This was after a conversation with a Diablo rep on another forum. I may be mistaken, though. It's happened once before.

 

Yes, I drive it in the winter when the roads aren't too bad. It doesn't have any tuning issues but I keep 10W40 oil in it so it needs to stay in a garage for the winter.

 

Ack. So it needs to warm up the components. Was just wondering about the underneath stuff (assuming thats where your Turbo is) cause although no real salt on the roads except that potash stuff, I figured you must have nice tubing and such underneath that you want to keep shiny. 1Unless I'm out to lunch and your Turbo is upfront with the Motor.

 

It is an improved version of my old STS setup with all the tubing being aluminized steel so it holds up as good as the factory exhaust. I used to install the snorkel for the winter but I don't bother any more as it is now too small.

 

Maybe that is where I saw it posted. I like the features of the DSP but I feel I'll need to do something about the rev limiter and the speed restricter. What is the stock RPM limit and speed restriction actually set at?
I'm shifting at 5900 rpm now so really not a big deal. I think?
I really went to the DSP to get a custom tune. So I'll be good with a custom tune if indeed it keeps the engine happy and makes power on the street. excuse the babble.....

 

If DSP says it's coming we gotta give them a chance.

Comfirmation Question WRT my e-fan warmed up the truck today and the e-fan came on for the first time around 194 degrees. I figured thats probably OK. Question is what is a good operating Temp, albet I got a 180 Stat doesn't mean I can keep it at that temp right. Even if that where possible which I doubt in the summer, wouldn't my gas mileage suffer.

So I guess the question again is ... 195 before it comes on OK or should I allow it to go higher. The switch is slightly below the Normal notch on the switch in the middle.

VATruck you mentioned yours don't come on till 205 or something but can't find that.
I know with the clutch fan my truck would hit 210-220 on the highway in summer.

 

Now that I have a gage to actually monitor the temps. I see that on the highway I usually have 186-188 engine and 140 -160 trans. In heavy traffic or data runs the trans gets up to 180. The engine slowly works it's way up to 205 and the fan comes on and the temp goes back down and cycles back and forth until I hit the highway again. I feel there is plenty of radiator and the fan does an excellent job of moving air once it starts to heat up. Today I'm suppose to recieve the HD2500 trans cooler so that should prevent any problems on that side.

 

So I confirmed that if you run a 180 thermostat (MG brand) with the factory clutch fan you will in colder weather especially get P0128 CEL's as it takes to long to warm up the engine/temp guage. With the e-fan added the truck warms up within parameters and that trouble code is gone away. Can't wait till winter again (Not really) so I can get heat in the first 5 miles of driving instead of 15...we'll see.

 

so you're saying the e-fan counteracts the disadvantages of the 180 tstat in colder temps?
