THIS IS THE ANSWER TO MY BOOST LEVELS. Cheers pumaspeed. Interesting question on the Boost. MAXD Out mapping is load based, not boost based. So, what this means is the ECU is trying to make a calculated torque figure. If the ECU/Map can match this request with only 20psi, it won't push any more. If the car needs more boost to get to the requested torque level it will push up the a preset limit in the mapping. Hopefully that makes a bit more sense :)
Please quickly for me, what was the main Problem. My English is not the best becase i am from Germany and have also Problems with my boost after 4500 rpm. i am right then i say it was a Softwareproblem?
@@PumaG3 Its not a problem, de ecu commands the dv open before full boost because its already at the programmed hp/torque w the small boost built up. So the car has reserves in it, could be pumped to more hp and torque with full boost utilisation
Interesting topic, my car is stock and was thinking of having a leak so all pipes checked etc etc, still only 217kps-220kps Now looking at MAF it's 155 So if believing the calculation that's 193bhp. And load is 98% so ECU won't boost more then it needs. Now, only mods are: cat back 2.5inch exhaust and mountune air box and filter, my take on this is car is breathing better/more freely so makes desire torque without need of hitting higher boost ✌️🤔😉
Also, bear in mind that on a stock turbo setup, most mapping will tail off boost from 5.5k to the top end as the turbo is past peak efficiency, if you tried to hold 1.55 bar to the redline then the turbo WILL go back fairly quickly. Its not the case for all stock turbos however for the most, the above applies. The 1.0 turbos on Superchips mapping will hold 22.5psi from 2k till just before the limiter.
It wasn't boost tailing off that confused me really it was the fact peak boost was hugger up hill compared to flat ground. But I found my answer why and pinned it as the top comment.
@@Sparkplugsteve some maps available for the ST180 from a certain tuner max out the load maps and set a single byte duty cycle limit to control boost. Poor way of doing it and if you fit a stronger actuator or have a boost control issue then the turbo will boost till destruction.
Should of got a Forge.. in response as for why ... I've logged all valves extensively, from measuring real world variables like effect on duty cycle, fuel trims, response time (you can measure the time it takes from the requested opening by the pcm) and even if you get any spikes at the throttle inlet during that time as well as the obvious peak boost number. For me the Forge has proven itself exceptionally reliable when installed correctly, gives the benefits of better part throttle response like the GFB with improved holding everywhere else, it uses a much higher pre-load spring as well as a boost reference signal, doesnt dry out the piston either so you could leave it a good 30,000 miles or 2 years before having to service it, unfortunately seen a few GFBs dry out in a short amount of time resulting in jamming of the piston and loss of boost, I have tried all types of oil from machine oil, engine oil, grease, you name it and it never lasts, in a hybrid application it also sounds like a pigeon and does nothing to reduce the part throttle whistle which the Forge virtually eliminates.
I'm surprised you haven't gone for a turbosmart BOV yet. Seems to be a very common replacement for the stock parts rather that revamping stock packs. Still, great content. I was going to do a video of the BOV replacement but it was a nightmare to get the angle...as you know 😂
@@Sparkplugsteve oh sh!t mate... worth a look to see if it still there. Great content once again. I had a boost leak problem once. I made a tool to test it. It involved a piece of tube with one end welded shut, two holes drilled in the welded end , one for a car tyre valve, and another with a gauge, removed a turbo boost hose and put the tool in it, then I hooked up an air line to valve and put 10 psi in. found the leak spraying soapy water on the connections. It's a little scrapheap challenge, but it worked.
According to the pumaspeed site it's supposed to increase throttle performance as well. I'm realy wondering if there is any real world difference to be noticed (unless your stock one is shot ofcourse). I'm not realy planning on spending the money if there's nothing to be gained.
Mine got stuck and i had only 1.1 to 1.2bar boost. i was almost ordering the new turbosmart em and the next day it went back to 1,5bar! i will open it nxt week and have a look at the brass cylinder. and yes mine is original!
This maybe of some help steve if you're still running cat safe crackle. After i got a gfb dv+ fitted, I noticed I was still only boosting to just over 1.5 bar. After a discussion with a mechanic who isn't keen on the crackle maps, I decided to load on my non crackle. I noticed the non crackle was version 8 and the cat safe was version 5 of 2R. After loading the v8 file, 20 mins into driving it I was hitting the 1.6 bar pumaspeed claim for 2R. I emailed pumaspeed about it, they told me cat safe stops at version 5, so it will be slightly down on version 8 boost levels. You can definitely feel it while driving, the mid range is a lot punchier on the V8 file. Maybe something for you to look into if you haven't already.
Awesome video! Have 16 usdm; installed mine and had no boost to - 12psi max lol. I’m reading all measurements on a COBB port and not sure how accurate it is. I took everything apart twice already; and even placed the og housing together (managed not to brake my plastic clip 🤪) and it was back to normal. Placed, the DV+ back on and like you said noticed a little difference after installing and now I’m just completely stumped and confused 😖
your turbo is simply running out of puff up the higher rpm range its struggling to maintain the 25psi due to the increase in consumption of the engine. the turbo will be best compromise for quick spool and being a good all rounder making the power it does from factory. every car iv had does this except for the ones iv fitted a larger turbo too ;)
Looks like it's making 34 extra psi there. So seems to have helped. But seams to make it up at peak torque from what i saw. So might be the map cutting it off when it hit that torque figure.
@@Sparkplugsteve sorry mate never read any of the comments etc just watched the vid and thought i would reply. My RS turbo will make peak 18psi and hold 15psi, obviously if the actuator etc wasnt up to much then it wouldnt be able do either reliably. Not 100% on this but on these st180s im sure iv read somewhere that boost isnt increased much over standard?
Maybe your ecu had adjusted to what the factory valve was doing and after a few pulls started to adjust to what the engine wanted to do with the new valve holding the boost the tune is designed for. I'm not sure if that's a thing it does but seems logical in my mind.
On my focus ST 225 the GFB dv+ retained the ecu control to hold boost slightly longer than the factory dv before dropping off, when revo mapped to high boost would hit the needle into red before dropping off, could be a ecu control to protect the turbo from blowing
Had a dv+ myself for about 15k km, but the cylinder inside the valve leaked after this distance. Changed now to the closed Turbosmart. Maybe this works better on long terms. So after all, I cant recommend the dv+ anymore.
Hi Steve, after watching your videos I finally bit the bullet and bought my own ST180 from copart. Progress is slow rebuilding it but it’s got a few aftermarket parts already fitted! I’ve noticed that there’s quite a lot of oil around the k&n pod filter. Have you ever had this with any of yours and have you considered fitting a catch can? Cheers!
Would you recommend the GFB? I’m running a stage 2 map and have heard that the GFP replacement improves throttle response and holds boost better. Or is it just less likely to go wrong compared to the stock DV?
@@SparkplugsteveSpoke to Ross Laird and Gary from collins performance and both have said they've noticed the GFB DV+ isn't very reliable after extended testing. I think Gary recommends the standard BOV and Ross recommends Turbo Smart Dual Port for reliability. Gary actually said the stock BOV is from a Mercedes which actually runs 2 bar of boost reliably!

The turbosmart stuff for the ST180 is shite. So many reliability problems whereas the GFB has had few issues

Throttle response is sharper between shifts for sure. The GFB closes quicker than stock.
I believe the factory ecu has a 16 sec over boost mode depending on the conditions
So what was the verdict? Are these parts necessary?
