Turbo 22-60 Vk injector nozzles+ 160% diesel Pump * larger Chanel inside and also 12mm pump head. large down pip large intercooler. My problem now is wen i lift pedal from throttle engine steal spin for a instant * instant bigger that original And a the idle car is not stable. what i have do until now, I reduce 15% in pump voltage and car stop the beaver at idle . steal make the delay wen lift car with original file and only -15% and map calibration for 4 b makes 200 Hp what i think that i have to do I have plx gauge with 4.9D senor , see AFR in all rpm and work with v until get a good base on pump map to start remap. but im a bit lose now. i leave here Log from vag with a short run Thank you Antonio Title: Vw Mk4 1.9 tdi 110hp with hard modifications Post by: Antoniovc on February 15, 2019, 09:35:03 AM I have Vw Mk4 1.9 tdi 110hp with some modification.

Its really fukin' hard to understand what you mean with broken english ? what the hell is a beaver idle and engine steal spin lol Get one of your mates to translate the post to english for you, I am sure somebody knows english decently in your circle Title: Re: Vw Mk4 1.9 tdi 110hp with hard modifications Post by: aef on February 16, 2019, 01:51:59 AM He is trying to say that his engine still revs or speeds when he lift the foot from pedal because diesel detonates by its self
this is not a diesel forum, you will not get any decent answer here. especially without file, story behind it and so on. did you buy this car? did you put all together and hope it will work with some internet tune you found or what?

Thank for your help aef and Blazius and sorry for my English aef correct me well. Im working on the car now and already have some results , i adjust idle removing V to pump and now i will start give some boost.

If you run 12mm pump and big nozzles idle IQs are nearlys impossible to control correctly. Increase idle-speed after pump voltage and SOI maps fit and problem still exsists.. btw.: running 200PS on VEP 11mm pump with bigger nozzles are enough an a lot easier to handle |
