If you check Log(1) On Stock Turbo DME BT was Normal in 6th Gear,
But in Log(2) after installing the PS2 the DME BT dropped little in 6th gear.
Now in Log(3) after getting Meth DME BT Drops A Lot in 6th gear.

It seems there is some type of limiter in 6th Gear, Maybe the Trans cant take that much of a Torque ??
Correct. I have been high lighting this issue to BMS and PTF for the last year. No body knows how to solve it. Looks like it happen every time TMAP read above ~20psi in low rpm. It does not always happen if you shift at high enough rpm.

2)Second log is the best that we could achieve with the PS2 - Before realising that i will need meth since the timing was really killed in the log because of the IAT's and low Octane in my fuel. Here we could reached 22 PSI HPFP was holding up - but timing was killed so in final tune without Meth and in this log we were targeting 19PSI

3)Third Log is after i got meth and the car is fully tuned now : With Meth we target much higher timing - close to 11 With 20PSI of Boost


What Do you think Guys ?
What happened to your AFR here? Try flat 20psi from 4000 and up - looks like you have enough fuel and octane to do that. IAT looks great!

raising boost targets up top won't make a change, turbo is already maxed out up top.

It is far from maxed out - look at your WGDC!

in Waqas car, the Pure stage 2 turbo is maxing out at lower boost:


maybe a boost leak ??
Peter@Pure, any idea ?

Either the intake system on the 535 has a huge restriction, or there is a boost leak.

Where do you see it maxout?, because wgdc is below 50 when.

It is very likely there is a torque limit in the trans. The 6AT had one, but we have been able to remove it with the xHP trans tune. I am not aware of anything like that on the 8AT yet.

When dose it max out ? is it On 50 or more ?? Because if its on 50 , then it reaches 47 in some spots which seems maxing out right ?

Not sure what are you saying.

Normal wgdc value on jb4 is from 0 to 100. So 99 = max-out turbo or boost leak. On your log shows 50. Now, I dont know whats the scale if isnt the regular 0-100

I think the Wgdc Value scales from 0-50

Anyone ??

No man, check one of your excel log the wgdc column. You will see values above 50.

Ok , Just to Try - I Did 3 logs

1- Trebila's Given PSI ( 20PSI Tapering to 16PSI up top )
2-4000+RPM - 20PSI
3-4000+RPM - 22PSI

So, I think from the logs Trebila Was Right, I Should not Up the boost - The Turbo is Maxing Out ( Boost is Not On Target )

What is your elevation? This looks close to PS1 levels. My three guesses are one, you have a boost leak. Two, you are at a higher elevation and this is the limit of the PS2. Three, you installed a PS1 and not a PS2.

Haha,
1)Maybe A Boost Leak ( But should be a small one ) Since it can produce some power.
2)Elevation (f) 59 feet
3)PS2

I had a boost leak and was capped at 20.5 psi flat. When I tested for a boost leak I could hear it at 1 psi. If you have a boost leak it is greater than mine was. This was at 175 foot elevation.

Wasqas/Yoandry...Understanding the left x-axis of the Interface

All values that are considered percentages: Throttle/Pedal/WGDC/FF/Meth/?? are displayed as 0-100% on the left x-axis no matter what you set it to on the settings page.

The other values: AFR/Trims/Boost/Ignition/HPFP/IAT...are following the scale. Dont set the scale below 50 as that might lead you to believe your trims are maxed out (50) even though they are not.

pure stage2 should do 23-24 psi at 6k rpm in 4-5th gear. If you only do 16 psi at 6k rpm for sure there is quite big boost leak. Unless you are at very high elevation which I dont think you are. Yes the turbo will make power still at 16 psi. However you are overworking the turbo which can shorten its lifespan. So I would check for boost leak!

WGDC goes from 0 to 100. However on the graph the values should be multiplied by 2. Also in graph above 40 (80 real value) is considered not much left in the turbo.

Could it be the hot weather in my country is the problem ??
Its 30C at night here when i am taking the logs

But i do have meth witch should eliminate the heat problem right ..??

My experience is tha hot weather usually allows for more boost. I could do 27 psi in summer and 23-24 in winter. However cold air has more oxygen than hot air.

16 psi at 6k rpm is really low. I would have the car checked for boost leak asap.

it could be a huge restriction on 535i, with stock turbo, boost wasn't exceeding 10 psi at high rpm...
on JB4 logs, when you read wgdc = 48, then real wgdc is 96%, so completely maxed out.
