Engine/Transmission (1998.5 - 2002) Quad-adrenalin

[BWagnaar]

So I just installed DDP150s and studs (studs are pain in the *****). I'm running the comp tune and when I nail it off the line or just rolling a little bit, as it comes up in the rpms right around 22-2400rpms it pops or crackles and feels like it defuels a tiny bit, than it bangs second gear and goes. Also I'm only getting about 28-2900rpms out of it on the top end. I thought it would fuel to 3200. My old TST set up felt like it would lite the tires way better once the trany banged second gear. The DDP and comp tune is SMOKEY!!..... CHoo CHooo!

i blew a boot the other night racing a rice rocket, needless to say i still smoked him but it scared the s$$$ outa me be she is still tickin, i am hoping to put studs a turbo and a exhaust manifold on (mine is cracked) my truck runs really strong doesnt smoke a whole lot especially when the boost comes up it clears out but it doesnt try to break my 305 all terrains loose, which my clutch slips a little so that might be why

Just some observations-I am setting here in Salt Lake City UT. after a pull from East Central AZ(5er 14,000#). Lot of different pulling conditions so steep some not so steep, etc. Interstate 40 west to Flagstaff and North US89 to Utah SR20 cut across to I-15 North to Salt Lake City, 660 miles. I have the Pulse set on level 4 and am using program 1025. I have it set to keep EGT below 1250. On pulls there where times defueled to 3, 2, 1 and sometimes even 0. It did keep EGT below 1300 which really is the goal. When defueling it feels liek it maybe missing or surging if you well is this because of the level jumping say fro 4 to 3 and back? Now if I go ahead and give more go pedal and pull it down to a solid 0 it does not do it, sound normal?

I also have my Pulse set in warm up to not let level jump from 0 to 4 unless it has water temp. above 150 degrees. Some times this is long enough I have mine set up to ramp up to 1200 RPM if the level is 0 and it idles for at least 2 minutes. I notice when this happened day for awhile is would fluctuate from normal idle RPM and up to 1200 then back down for awhile and once the temp climbed some but still below 150 it went to 1200 constant tell warmed up then level jump to 4 and high kicked out, sound normal? Finally stopped form some construction flagman and I have my Oil pressure warning set at 30 psi. While seating there the warning came on showing pressure was like 26 PSI I did not expect it to be this low though I think that is ok, you guys agree?

Will be reversing myself going back and will let you know if I see anything else.

Home from Salt Lake and basically everything the same as I described above. Since no replys either everybody has the same things happening and agree all is ok or no one knows for sure?

Sounds like torque management. My truck fuels past 4k rpm.

 

[Bob Cochran]

Well I think mine would also but I have it set to keep EGT below 1300 so set point 1250. It seems when defueling to keep EGT below set point it surges/jerks almost feels like a miss.

I set my de-fueling at 1450 because I don't think the Pulse is that acurate compared to my analog Pyro. When I plug the Pusle into my computer it can't find it. I tried three different computers even with the driver they have on their site. Both the Adreniline and the Pulse use USB 2. 0 plugs.

I had to use windows vista to update my pulse.

 

[Bob Cochran]

I don't want to take any chances maybe will raise my seting from 1250 to 1300.

For all Pulse owners Quad gave permission to post explanation of tuning so we will know what we are doing!

Pump Stretch.

This will make the biggest difference in overall power and smoke. This is the amount of time the injector is actually opened and spraying fuel into the cylinder. I have this set pretty low on the 1000 tune that I sent you. The COMP file is set to 1800. More than 1800 creates more torque and a lot more smoke but, actually makes less power on the upper end based on all the trucks I have had on the dyno. This is where the COMP file is set to. Feel free to run it to 2400 anytime you want lots of low end power and smoke but, realize you are giving power up on the top.

This does not mean you will get this amount of fuel all the time. There is a map, in percentages based off of this number as the maximum. Beyond that the map is also scaled by the TPS. So even if the map commands 100% but, you are at 50% throttle you will be getting 50% of the max stretch. If the map calls for 25% and you are at 50% TPS you will be getting 12. 5% of the max stretch.


TPS MIN. For both CAN and Pump fueling.

This allows you to set at what TPS% the module actually starts fueling. A higher number will be less aggressive, a lower number such as 0% will be the most aggressive. It is important to watch TPS% on your Pulse in determining when you actually want to start fueling. We set this at 30% on most tunes as that is about the min TPS% you will see while driving in normal conditions.

TPS MAX. Both CAN and Pump Stretch.

This allows you to determine what throttle position you will see max fueling at. It also re-scales the entire map based on what you select. This is set to 100% on tunes I sent out. This means that you will not get 100% of the map unless you are at 100% TPS. If you set this at 80% TPS that means you will get 100% of the fueling at 80% TPS. It also means that 80%=100% and the map is scaled between 0% and 80% but, on a 0-100 scale. In other words the map moves in increments of . 8% instead of 1%.

This can be really useful for those that drive light but, want power on tap earlier in the pedal but, not necessarily right off idle.


Timing MAX

Sort of goes without saying. 0 means we do not add any timing. 10deg means if the map calls for 100% you will get 10deg added over stock.

I never go over 7. 5%. In my opinion that is more than plenty. If you are going for only mileage and are going to be easy you can use 10 deg and it should be great for mileage. The problem is that under much boost it could easily cause headgasket damage.


Boost Scaling.

This function is more of a smoothing function of the map. There are 20 positions that this function controls. Think of it at columns. Until boost equals a certain amount, then it is in a certain column. It takes more or less boost to move to different columns.

So if you set this to 20, then each column is changed by 1psi. If you scale it to 40psi then every 2psi it changes.

While this can make things more or less responsive or smooth it out slightly it does not make huge differences because not necessarily every column is more or less aggressive than the next. There have been maps in the past and there will be maps in the future where they will be more boost reliant. For now we do not rely on boost that much other than as this scaling function.

Has anyone used the new Adrenaline program that is supposed to stop the surging. Did it stop the surging was there any other problems that showed up with this program?

I think for me playing as you said above Rick will; just get me into a lot of trouble!!!! I can see it will be great for others.

 

[monkeyman]

What is funny, is that I don't get surging with the 2025 program. But my truck is highly modified. Have not used the custom features yet on the Pulse as I just got it back.

Yes, the new no surge tunes are perfect on my setup. I had some surge/bucking issues on all previous tunes that you could drive through but, who wants to do that ? The custom tune ablity is great. You can make it as mean, mild, or smooth as you want.

 

[Bob Cochran]

Thanks will make the update as soon as I get the chance already have it down loaded. I felt the surge most when pulling the 5er up a grade and not much without load unless accelerating semi-hard.

[RSimmons]

I have not tried any power level over PL1 when towing because I have all I need with injectors. I used to get some surge even on level 1 (timing only) but that has been fixed on the new tunes also. Even unloaded I used to get some surge\bucking that seemed to get worse the higher the PL. I now can run around unloaded on PL10 with no surge. I did raise the pump strech (wire tap fueling) minimum to 45 TPS so I was not bumping it with normal driving. When you get on it, hang on!

 

[GOTSOOT]

why did quad not put a disconnect in the wiring harness so you can remove the pulse to update! not every one has a laptop. ?Am i missing something?

 

[Bob Cochran]

Right now I have Adrenaline module on my bench and very frustrated. I have a new laptop with Vista Home Premium and followed the directions exactly to down load and program the module with the new tunes. It cannot find the driver for the thing!!!! I had done this on my old laptop using XP to update tune last summer and had no problem. I have an email to Quad about the problem. I may have to take out the old laptop and load program on there to program the module. Lot of people do not like Vista but I am trying to be impartial and just assuming it is just different from XP and will like it once I get used to it.

I am sure Quad will provide the answer for me but has anyone else had the problem? What did you do to solve it?

 

[DCreed]

windows stinks, period!

 

[AllianceDiesel]

mine took forever to download with vista, but now that its seen it before it works just fine.



On a side note, has anybody heard of the adrenaline starting to smoke, buddy was jumpstarting his truck, he looked over at the chip and he said smoke just started rolling out of the box, he hasn't tried starting the truck since. I havn't had the chance to talk to quad yet.

 

[DCreed]

box it up and send it back to quad. the newest tunes are supposed to help prevent that.
