Just ordered a 160 t-stat as well, anything from a 05 + LS2 will work, as they have the T stat seperate from the housing, unlike prior LS1's that need the whole goose neck.

Looks like it will be fun to change, as one bolt is pretty concealed near the ex manifold, and not to mention the massive amount of coolant it will **** upon removal LOL. Better than running at 200 degrees all the time and having 90 degree IAT temps regardless of ambient.

 

AWESOME!!!! Nice cars & good tuning!!! I sometimes miss my '01 Monte SS, which I am sure is no comparison to the '06' SS's!!

 

Yeah i have my fans set to come on full speed at 200 and it still runs over 195 all of the time. It immediately goes up to 210 or so after coming to a stop after driving a few miles.

Thanks for the info... didn't know the LS2 t-stat would work. Probably will get a 160 or 180 myself. Needs a transmission cooler too, ive just been to cheap and lazy to get one so far.

 

Couple more pics of the monte and the Camaro.

I had a guy take professional shots of both car this weekend, i get the CD from him today. Ill post more of the JUST monte later. Gonna try to get the Camaro in GM hightech with these, maybe the monte too at the same time if i do some more mods to make it worthwhile hahah

Some of you with sharp eyes will notice the slight visual changes for the better i made to the monte.

 

Well, I too took the plunge and bought hp tuners. Sounds like every mod you put on these cars, you need to change something in the computer. Hopefully I can get some help from you guys when I start tuning. I'm sure I'll just do some minor stuff at first.

 

hey i have no torque managment and i maxed out trans line pressure i think. sitll doesnt chirp into 2nd or feel that hard of a shift. what are u doing to make it chrip 2nd at wot?

 

Just started tuning yesterday on mine. Removed 1/3 of the TM on shifts, upped shift pressure 10%, seems like the shifts are not as 'managed'. I like it, more tinkering to follow. Anyone notice the max torque per gear? Looks like 1st gear has a limit on it, but the rest are wide open. The calculated torque is pretty high, but I wonder how real world based that table is. Anyone pull that yet? Looking for a little preview until the next chance I have time to tinker.

 

I just made 1st gear equal 6046 like the rest of the gears in the max torque table. Im thinking it probably got rid of the abuse mode when you get too much traction at full throttle from a stop. (when it kills the throttle and makes you eat the steering wheel) However I haven't tested that theory out yet so im not sure what changing the values did.

I haven't messed with any of the other torque values under engine torque management yet.

 

hmm we did that to mine as well but i still dont chrip 2nd gear at wot

 

Got my tuner today!

Basically just doing what you guys have done so far(shift points, rev limiter).

Also wondering where you guys are getting rid of the torque managment? There a few areas that can be adjusted from the looks of it. Is it in the engine tab or transmission tab?

Really awesome product!

 

Under the engine torque management I only changed the Maximum Torque (RPM vs Gear)... set the 1st gear values to 6046 like the rest.

In the transmission torque management I set both abuse mode tables to 0 in all fields. In the torque reduction tables I set the 1>2 and 2>3 shifts to 0 in all fields for both normal and perfomance mode. I removed about 80% of the torque reduction for the downshifts.

However after I removed all that torque management I noticed it was not grabbing good when shifting during heavy throttle.(kinda shuddering) So I bumped up the shift pressure tables a bunch. I have 1st gear at max pressure at 207 ft lbs and higher... then smoothed it down to the lower torque values. Did pretty much the same thing with 2nd gear except I set 85 at the highest value. Basically I added alot to the mid-area of the pressure table. Once I got the normal table looking like I wanted I just copied it to the other 3 pressure tables. (im not sure what the "power/brake on" tables are for) Also copied it to the 2 downshift pressure tables.

I really shifts good now at full throttle... I still have alot of driving to do to see if I like it though.

Set the WOT shifts at 49 mph and 6100 rpms... and the rev limiter in gear at 6200 rpms. Even with the 49 mph shift speed it still shifts a few mph higher. That took some messing around to get it close to the rev limiter without actually hitting it.

Don't know if anyone else has the problem, but my TCC was slipping under very light throttle above 60 mph. I multiplied the lower TCC duty cycle table by 2 and it has stopped.(thanks GM)

Also on mine the minimum and maximum TCC duty cycle are labeled backwards. It is pretty easy to see cause the low values are in the maximum table and high values in the minimum table. Just ignore the names.

Adjusted the fans to come on sooner. Changed just the table based on ECT. It keeps it a little cooler, but not much.

Of course I set the speed limiter to something higher than 140... I think 155 or 160... can't remember.

Did a bunch of adjusting to the part throttle shifts. You just have to adjust them to what feels best plus they also need to sorta match how your full throttle shifts are set.

So far I haven't done anything to the engine tuning... I have a wideband just been to lazy to install it.

 

hey where are u guys getting this tuner to get rid of the torque management? I have an Impala SS and cant stand it. i also just realized that my car calls for 91 octane or higher and i have been puting in 87 for the past 5 months i have owned the vehicle so last nite i put in 93. do u guys think i'll notice the actual difference?

 

So far on mine I reduced the torque reduction vs. torque vs. shift (& downshift) tables in the trans torque management section by 33% and added 10% line pressure to the shift pressure normal/performance/normal brpwron/performance brpwron in the shift properties section. Still wondering if the thing actually uses the performance or normal tables as there is no performance or tow switch in the car, but I changed em both anyway. Much smoother now in shifts and you can feel a little bit of a shift now too instead of mush land. Got rid of that max torque in first gear thing too. Timing drops less, but still +1 ATDC in shifts if I am reading the scanner right. Big help nonetheless. I think I'll try 50% torque reduction next.

I looked over the scanner charts and timed 30-60 mph before and after (this includes the 1-2 upshift. On the 2 runs I compared so far just doing what I did so far reduced the 30-60 time by .4 second! It was hotter on the day of the stock run, but still, something to consider. I'll do some same day tests later, but I thought I would mention this for anyone thinking what doing some tinkering would do. Gets rid of the noticable power drop in shifts for sure, I'm impressed.

 

HPTuners.com. The low octane table has lower timing settings mapped to it, so I would think if the engine sees spark knock it will switch to the low octane table and the corresponding reduction in power. I've always put premium in, so I dunno if it noticable seat of the pants wise. At maybe $5.00 a fillup more for premium, why bother with regular unless you are just going to sit on the highway?

 

I think I'll correct a little bit of internet rumor I might be starting here....I looked over some more runs and that .4 second might not be true afterall, so please ignore this boastful remark!

I tried out dropping the tranny torque management in shifts to 50%, but looking over the line charts for the runs, I kinda get the feeling that the tranny is starting slipping some after the 1-2 shift with 50% TM removed. Nothing major, it grabs after the shift, but comparing full TM with 33% removed and 50% removed, I feel more confident in leaving 33% TM removed in the car. The 33% removal makes my issue with how the TM works disappear, so I'm happy.

 

that isnt the DOD, that is the fuel cut off when u let go of accelerator. as of now u cant adjust the dod on the car

 

Adjust some of the settings and see if it makes a diff or not...

DFCO stands for decel fuel cut off...

however they DONT use this on U.S. issue cars due to the fact it increases Nox emissions from a leaner mixture.

It is a convienent place to put the controls w/o making another tab and makes sence to me.

I moved mine up to 40% throttle to dissable and raised the g/cyl for the maf input like 15%

And sure enough.. scanning it shows it disengages right at 40% throttle when cruising around town or a higher g/cyl than what i have in there (more engine load)

 

dumb question
what the hell does the credit thing mean?!?!?
im pokin around the hp tuners site and see the credit deal. is this how many times you can flash the ecu? or different amount of cars?

what package did you guys get?

 

Each car requires a certain amount of credits to tune. You get 8 credits when you buy HP Tuners... our cars use 4 of those (which leaves you with 4 more that you could use on another vehicle). You can always buy additional credits to tune more vehicles. Older model LS1s don't require as many credits to tune, while the newer cars and trucks usually take more.

This has no effect on how many times you can flash the computer. Ive probably done it 50-60 times now. You can keep flashing it till the world ends.

 

Unless im missing something I really don't see how that could be controlling DOD. The stock settings on mine would have it cutting off DOD at more than 20 percent throttle. Which would mean it would never cut on since throttle percent stays around 30-35 on the interstate.

Besides there are a ton of variables that the computer takes into account to decide when to use DOD so I would imagine that GM would have to have wrote specific code for it. Plus the guys at HP Tuners said they hope to incorporate some DOD settings in future releases.

I have no proof... I actually have no idea at all. Just doesn't seem logical.

Also just curious... what are you logging that would show whether DOD is on or not. I never really found anything definite. I just kinda judge based on sudden changes in MAP and MAF output.
