Ok, took the Wastegate apart while under the car and since it was upside down you can immagine the work, anyways, it had 2 springs in it, a green one and a yellow one, the yellow one was HUGE so I removed that one, put the W/G back together and drove it, the car now see's constant 21/22 boost and holding it, just at the end of each gear it spours so its something to do with the Pdi (ez) fix. Now if that green spring is 21 lbs, what the hell is that other huge as spring inside of it...lol.....in tomorrow for another tuning day and c, if not Ill try going back to regular 93 octane.

 

I think u should give turbosmart a shout before u start disassembling and leaving out pieces of such a vital part. That spring combo probly added up to a certain pressure. Different combos different pressures

 

sounds like your running outta fuel up top like i told you.

 

It's your fuel map, it's got a nasty hole. That's why your unloading in third.

 

^^^ lol this guy..............hahaha.. but have Joe send me a log on the final ones.. ill look at it and send me the tune so if there is somthing I think that would needs adjustment

 

sorry, i had to. couldn't resist.

 

I would have if you didn't...

 

If there were 2 springs, its a 14psi and a 10psi spring. So you running the 14psi spring.
prob the boost controller is active to give the extra boost. Ive never scene that amount of boost with just a 14psi spring.

 

Correct me if I'm wrong but a boost controller can only raise boost above what the w/g is set at so if the w/g was at 24psi and the controller is at say 23 psi wouldn't they be fighting each other and in a car like the lnf you would have tuning issues?

 

You can control boost with the lnf pcmcia, yes is it more difficult to manage? Yes.but its possible. But you can not get less boost then rated spring

 

It's a ******* boost controller. You act like your some god with this ****. Besides the fact that I know 2 big turbo lnf's running manual controllers just fine. It's going to read boost through the maps and make adjustments either way.

 

Your correct it is a ******* boost controller. No Duh ... Did I say i was a god. No I ******* didn't. Using just a boost controller actually does cause drivability issues .. you calling for a.commanded dal and mal and also using proprtional, integral, and deriative gains and a wgdc. So therefore the ecm willl act as if its failing somewhere .... I've tuned.plenty enough of Tq based ecms to know what im talking about. The drivability issues may not be badly affected.but the cars power may or may not surge in areas or the car will shutter, stutter ect..

Yes you can disable all the codes, woopdy doo. But it still doesn't matter.. the car will act differently to just a manual boost controller then to the cars actual controller with a possible online manual controller.

PID controller

A block diagram of a PID controller

A proportional–integral–derivative controller (PID controller) is a generic control loop feedback mechanism (controller) widely used in industrial control systems – a PID is the most commonly used feedback controller. A PID controller calculates an "error" value as the difference between a measured process variable and a desired setpoint. The controller attempts to minimize theerrorby adjusting the process control inputs.

The PID controller calculation (algorithm) involvesthree separate constant parameters, and is accordingly sometimes called three-term control: the proportional, the integral and derivative values, denoted P, I, and D. Heuristically, these values can be interpreted in terms of time: P depends on the present error, I on the accumulation of past errors, and D is a prediction of future errors, based on current rate of change. [1] The weighted sum of these three actions is used to adjust the process via a control element such as the position of a control valve, or the power supplied to a heating element.

In the absence of knowledge of the underlying process, a PID controller is the best controller. [2] By tuning the three parameters in the PID controller algorithm, the controller can provide control action designed for specific process requirements. The response of the controllercan be described in terms of the responsiveness of the controller to an error, the degree to which the controller overshoots the setpoint and the degree of system oscillation. Note that the use of the PID algorithm for control does not guarantee optimal control of the system or system stability.

Some applications may require using only one or two actions to provide the appropriate system control. This is achieved by setting the other parameters to zero. A PID controller will be called a PI, PD, P or I controller in the absence of the respective control actions. PI controllers are fairly common, since derivative action is sensitive to measurement noise, whereas the absence of an integral term may prevent the system from reaching its target value due to the control action.

 

Now if you read through this, you'll notice you have commanded values and all three work together. So if the Pid is not seeing these values it will act differently ecspecially since its not seeing the actual wgdc or sending anything to control the wastegate.

 

O yeah I'm also a big turbo lnf ad I run straight boost controller inline with my wastegate and Pid. Never said you couldn't do it..

 

Want to know how I know you didn't type this post?

BECAUSE I CAN ACTUALLY READ IT.

you continue to say it will act "differently". I really think you're just full of it.

 

Lmfao yeah .. I did write that post there. You know the one you replied to.. the one before I even said it was from wiki. Lol. I'm full of it hahah. Yeah ok Mr zzp man.. lol .. tune a large lnf with just a boost controller and notice the differences. it will be a lil different. Lol.. ah .. your full of it.

 

Lsj isn't Tq based is it ? Lnf is a Tq based ecm.. there's a big difference. Not once did I say you couldn't do it. I've done it before but i run the boost controllers in line .... Since its ran online the ecm still pushes the calibrations through the Pid and amcan control it.

 

You'll notice the difference. It'll be a little different. Go jump off a bridge or tie your hpt cable into a neuse.

 

Lmfao comes from the guy who hasn't tuned a lnf larger turbo more then likely. So go jump off a cliff and sale Ure tuning cable since you wanna talk ****... Kid

 

Little difference / difference. Still drivability differences ..

 

At least I can type like an adult and not like a ******* retard....kid

 

Why are there so many douche bags and haters on this forum?

 

Your right. Talk **** about online grammar! Your such a big kid....

 

And boosted I'm not hating. Im just getting a correct point across lol..

 

This is Richard's buddy Wes. I wasn't talking about you James, I was talking about the flaming guy
