Title: MED17.5.5 Boost Problem Post by: VagHead on August 07, 2020, 02:35:15 AM Hello everyone ! I'am new at forum and tuning world. I'am trying to tune my own car 1.4 tsi 6j ibiza cupra. I have hybrid turbo, intercooler, forge wg , watermeth kit. Now i'am running with 15.5 ignition timing advance but i can't increase my specified boost more than 1.5. I want to 1.8 peak boost. I take 1.7 peak with Forge Wg after that it decreases 1.5 fast. I couldn't increase my specified boost. Anyone can help me about this ?

Please consider reading and fully understanding the s4wiki Gesendet von meinem ONEPLUS A5000 mit Tapatalk Title: Re: MED17.5.5 Boost Problem Post by: VagHead on August 10, 2020, 04:09:18 PM Your target boost capped with LDRXN, and Max compressor Ratio, Please consider reading and fully understanding the s4wiki Gesendet von meinem ONEPLUS A5000 mit Tapatalk I have read the S4wiki. As far as I know there is no LDRXN for MED17.5. Does MDMAXNMOT do the same as LDRXN?

You cant request more than 2590mbar in charge, only on intake... it will eventually go over 2590 and start decrease to achieve 2590 on charge Title: Re: MED17.5.5 Boost Problem Post by: Blazius on August 11, 2020, 01:33:19 AM This has been asked many many times.. Its similar problem to me7 but in different clothing, unfortunately for solution you gonna have to pay as nobody wants to share it really...
In addition to that , fairly sure that 1.4 tsi me17 also has svbl.( could be wrong ) Title: Re: MED17.5.5 Boost Problem Post by: VagHead on August 11, 2020, 08:34:27 AM Yes, work like ldrmx... but % of maximal torque.

Now i couldn't see more than 2500 mbar Title: Re: MED17.5.5 Boost Problem Post by: VagHead on August 16, 2020, 12:51:22 AM Hello everyone ! I'am new at forum and tuning world.

I increased KFMIRL %40 from ori file. I ıncreased MDMAXNMOT to 65535 . I tuned some torque maps end of the file. Now I can run 2bar peak and 1.7 cont boost Title: Re: MED17.5.5 Boost Problem Post by: ktm733 on September 04, 2020, 07:33:29 PM Thank you for helping that community.

Title: Re: MED17.5.5 Boost Problem Post by: nyet on September 05, 2020, 09:39:34 AM increased 40% IRL across the entire map?
That's not really ideal either :( Title: Re: MED17.5.5 Boost Problem Post by: overspeed on September 05, 2020, 01:16:26 PM Even requesting 300% on KFMIRL, MDMAX 100% and PV"stuff" to 3200mbar will not chance you requesting 2599 on charge... only allow you to pass throught this value on manifold... but n75% will decrease until charge pipe stay near 2599mbar.
There are 2 requested pressure, one from torque path (kfmirl/kfmiop/mdmax) and other from turbo protection, that will limit your pressure on 2599 top Title: Re: MED17.5.5 Boost Problem Post by: VagHead on November 13, 2020, 02:06:29 AM Thanks for reply !
