HPtuners fan on/off points

[flyingfool]

JUst zeroed out the slip tables on the TCC, wow it feels so good when I get full lock up now.  Also set the min speed in V4 mode down to 40mph this seems to be a better place to have it activate.

 gonna start increasing my shift point speed , then increase clutch pressures and firmness next.

Did you remove TCC lock up in gear 1-3.  That made a big differnce to me.  I drive arond town alot so I like to leave 4th locking up.

yes, 1-4th disabled, I swear it feels like a higher stall converter, the truck now accelerates friggin fast, and no hesitations anymore  when stomping on the gas. i wish i data logged before and after HP numbers, feels like 15hp seat of the pants

 

I discovered a new window section which list eco mode, i assume is DOD v4, normal,tow, winter, and sport... what is sport mode?, and can i sync it up to a custom trans map via tow haul button something to activate and toggle manually pattern xy,z would be cool!  i know the camaro has this feature, can we splice this into the trucks?

You can set the tow haul mode to shift how ever you want.  I left mine pretty close to stock because I two a big wakeboat.

 

I really don't feel necessary though.  With the right shift pressures it should snap off gears at WOT and still feel smooth at part throttle.

I wouldn’t change the EQ ratio until you have a wideband.  You can get good gains with part throttle tuning using your STFT and LTFT.  Just tune your fuel before you go into power enrichment.

is there a better enrichment ramp-in /ramp out time for the PE table vs stock .050

Any lower than this can cause a fuel dump situation and creat alot of black smoke on the hit when going WOT.  Or at least it did on my truck.  I'm pretty new to tuning but I feel lke I'm picking it up pretty well.  Ask any question you want.

i notice the COrvette file i have keeps the PE  pedal a flat line 70 % while your settings taper off

[JONBLARC7]

I tried it with higher numbers at the upper RPMs.  But what found was if you where holding a gear and then rolled into WOT smoothly.  I could create a situation where it doesn’t go into PE.  Had it happen a couple times while I was logging and making second gear hits

 

remember Vettes are much lighter and it take a lot less effort to get them moving.

have you tried setting the rpm activation point to 1200 or 2000rpm? 

 

I also discovered the ramps in /out time prefers a factor of 1.0, and not .050 on stock

 

i am getting confussed on the ECT min max, temps, i will try your numbers , i think mine are backwards.

 

Amaized at how hot the truck gets when i do a pull, i got the cooling fans pretty well dialed  in, but they are always running even at 40% but maintaining my the 178 temp. I wonder if the radiators are a bit undersized for the power output and weight of the truck?

The only time I’ve had them higher is when I was tuning form part throttle fueling  tuning and I didn’t want it to go into PE.

Those PE settings are low, that is going to cause you to go into PE any time you hit the throttle hard off of the line in a part throttle situation. It can cause you to run really rich while in Closed Loop and can eventually fail the front O2 sensors. I keep the PE enable close to stock up until 3k RPM's, then I drop the PE enable to 45% throttle and reduce the RPM delay as well.

 

You dont need or want to be entering into PE just because you goosed it hard coming off of the line.

Can’t AFM be completely turned off as well with a tuner?

yes it can, i just like it active on the highway, its very simple to tun off with the software, lots of vids on youtube giving a full walk thru if needed

i will be increasing my setting higher rpm, my gas milage is around 11.5 mpg. mind you the truck feels so amaizing to drive around town. for a 5000lbs truck it feels like a hot rod now, but its eating fuel like a beast

 

i will also try disabling TCC 1-3rd gear instead of 1-4th, i kinda like a more solid connection in 4th after driving around for 2 weeks now

That’s what I figured. I’d like to eventually have my truck tuned once the power train warranty expires in a couple of years.

for the cost of a throttle enhancer or a DIablo tuner crap, just buy the mpvi and the credits from summit racing  for your truck, there is soo much tweaking of basic stuff that enhances the durability and performance,
