Note: When tuning the car, be sure to data log several sessions prior to making small changes. There is a learning period associated with PID controls (Proportional gain, Integral gain, and...

I did some more tuning lately and it yielding some serious gains and grunt down low. One thing I noticed is that if you place all of the higher kW in the (Engine>Torque Management>Engine>Driver...

I think I have found the key to closing throttle and KR at WOT. Its all about reducing the turbo duty cycle so that the actual boost doesn't exceed the target boost. Data log the following info:...

I just cranked up my base duty cycle X 1.15 above 2200 RPM and did a data log. Currently all max torque tables are 600 ft.lb, Knock Air Mass is 2.0 at -2 and up, Boost Max is 260kpa, and driver...

Word to the wise, don't mess too much with the Wastegate Open Boost map or you will see real knock.

I was actually logging many different values to see if I can find a trend between them and the issues I was having. I attached my current config file.

How much did you raise them and where? Can you give us a compare picture?

More specifically it is the engine torque exceeding the Boost Engine TQLimit. This TQ limit is not the TQ limiters in the TM>General>Torque Max maps. I need to figure out what is driving the Boost...

I get the Knock Air Mass. My thought for the pressure delta has more to do with WOT downshift response. Lets say you are cruising in 6th gear then you stomp it. I want to boost to respond quickly. I...

So I am looking at all of the boost control setting in the Engine>Torque Management>Turbocharger section and I am trying to make sense of the maps here. The best way I can do that is to try and...

I reduced the knock air mass per what ATS4me suggested and the tune is a little more consistent. ATS4me can you explain how you are moving the TM out of the way?

I agree with the sharing aspect on this forum. I'm not sure why folks want to make is a guessing game and only providing hints to issues they claim that they figured out. Here is what I have so far....

Any chance we can get some more specifics? I'd imagine you would advance the exhaust cam and retard the intake cam to limit overlap. Can you post up a tune?

Now I can datalog KR per cylinder and intake/Exhaust cam positions. Hopefully I can figure out the KR in light load, and I am still seeing some KR under WOT but it is not consistent. I believe that...

Bill resolved the PID issue for me. Thanks Bill.

Here is a screen shot. Perhaps there is a newer Beta version I should be using?:banghead:

I have been monitoring commanded AFR and it is between .80 and .78. There is some Knock Retard but it doesn't seem to have any relation to any other variable. Many times it is just cruising. I even...

I looked and none of these are available.

I have been monitoring those PIDs and since then changed the tune. Here is what I have currently. So far so good.

Knock retard, Torque, AIT, Commanded AFR, Max allowed Torque, etc.

I have been following Ghost and others as they tune their 1.4T to get an idea as to how to tune the E39 ECM. They seem to be pretty similar. One sort of issue I found was when you raise the Turbo...

I have been reading through all of these 1.4T tuning threads to get a grasp on tuning my ATS. One thing that I didn't see pointed out is that if you raise the Turbo Overspeed limit Min = 2.00 you...

What version of software was this? I tried the VCM Scanner 2.24.99 but it would not recognize the ECM. Also any update for the ATS 2.0T compatibility? I purchased the Trifecta tune but I honestly...
