I have gauges too. but now i can monitor so much more.
have you tried the new tunes on the site. They are supposed to stop the surging issues.
with custom tuning you could try this.
From Quad "Then I want to you to set the TPS Min for BOTH Can and Pump stretch up to 25%. Tell me if that helps.

Basically this will not let the truck start fueling until 25% TPS is reached.

I am not sure why this is needed but, it seems to only be there with the automatics. Setting the TPS MIN up to 25% seems to cure this.

Let me know what you come up with."
I tried it and it worked. Now with the new tune i have no more surge.

 

I don`t have surge with the new tunes but the comp tune has less power then the 2000a test tune i was using

 

Tried the New Comp tune today and runs smooth so far. Havent update the pulse yet.

Ive got a Pulse with your name on it DM

 

Guys with pulse! Try this,

set fuel stretch to 2200,
timing to 10*,
can min to 30, max to 100%,
pump min to 30, max to 100%,
boost scale to 25.

Surge free, killer bottomend, totally sick mid powerband! Strongest tune ever!!!!

 

Im just a poor boy from a poor family ......



I have some OT hitting this week so maybe you will be seeing a price quote thread soon ,

I dont have a lap top will i still be able to tune the pulse?

 

You will have to either get a long cord to reach the pulse from your desktop or just remove the pulse to download new updates.

 

Ok ill remove it then , right now its in a different state i'm not sure which one

 

Just update the pulse to the custom tuning in you first get it and you will be good to go until Quad releases a new update.

 

Cool , ill be getting one soon

 

I borrowed this from the other site. It explains more what you can do with custom tuning.
Quad wrote this in an earlier post when the custom tune beta started.....

Ok, I am going to give a rundown about how each tuning parameter works. I am going to do my best to explain this in plain english.

To start with, the test file I sent you is pretty mild but, can be made into the COMP file really easily. For the most part the actual fuel maps are the same across the board. Yes, there are a few different ones out there and when we actually go live with custom tuning we will also have more downloads that offer nothing more than map changes.

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 make the throttle lighter or more responsive. Basically it gives you a fudge factor that allows you to get a minimum amount of the max fuel stretch all the time. If you set this to 10% you will never get less than 10% of the fuel map. So if the map calls for 100% (1800) but, you are at 5% throttle you would normally get 5% of the map. If you set this parameter to 10% you will get 10% even though the mapping algorithm calls for 5%.

You have to be somewhat careful with this or you will be fueling way too much at light throttle. This is set to 0% on the tune I sent out.


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.



Hope that helps. If you have questions please let me know.

To turn your custom tune I sent you via email into a COMP tune follow these guidelines:

Timing = 7
Fuel Stretch = 1800
TPS MIN = 0 (both can and pump_
TPS MAX CAN = 100
TPS MAX Pump = 70
Boost Scaling = 25

Wholaa, COMP tune
