they are at 3200 absolute peak bars, after the boost pressure stabilizes at 1.8.
if I'm not mistaken the compressor map is the KFLDHBN right?



No, the compressor map for K04s.

3200? Seriously? Are you sure about your numbers?

So you are totally clueless, need a map pack or a damos for your file, and yet *somehow*, you've managed to modify A TON of things in that file, that would be unpossible to modify properly without a damos. So what the hell is going on here? what aren't you telling us?

absolutely guys I won't hide anything from you. Then I'll explain more clearly how things are. I have the damos for my file and I made all the changes doing tests on proofs and reading your forums. But now I have reached this point, the throttle valve chokes me when the car overboosts at 2200 mbar and I can't solve the problem in any way

And you determined you can't solve the problem without logging using ME7L?

Nye come on man! How would he use ME7L on a MED17.5 ECU?

hi guys, then I proceeded to make a small log, unfortunately for now I can not do anything else because here in my part it rains a lot and therefore it is dangerous. As you can see the boost pressure is not the law, but it stops at 2550 mbar, but from the log you can see how the butterfly closes and then reopen above 5000 rpm. I'm trying them all, now I'm sending you another map with which I logged. I thought I had found a torque limiter at the end of the map I tried to put it to the maximum but instead nothing does the same problem.

then guys I would like to recalculate KFMIRL for good.
I read that to calculate it you have to do MASS MESSAGE / MASSA STANDARD.

The problem from what we see in Log is at 3000 rpm, at 3000 rpm it ingests about 240 g / s of air, so I do this operation


[(240 * 60/3000 * 0.5)] / (cc 496 x 0.00122521)

The problem is that I get a wrong value, where am I wrong given that I get out 16? Can you help me?

Hi guys, I thought maybe my problem could be too much difference from the requested boost pressure and the actual boost pressure. In order to have a different boost request would it be right to intervene on the KFPED?

What. The. FUCK?

How on earth did you get that impression.

The s4wiki outlines EXACTLY what goes into requested boost.

I'm sorry, I don't understand why you always have to respond in this rude way. I'm asking questions with education. I have read dozens of times s4wiki on the tuning page, but I have not understood how to outline the request for the boost, and based on what is precisely calculated. There are dozens of acronyms and with the translator everything becomes more difficult. Can you explain to me roughly?
