Title: Max charge pressure exceeded Post by: shelev on December 20, 2018, 07:23:28 AM Hello!
I have a problem with the Nefmoto stage 2 firmware, when I switch to second gear and press the gas to the floor, I get an error regarding the increase in the maximum boost pressure — permanently. (at this time there is no boost, but as soon as I let go of the gas and press it again the boost appears) On 1, 3, 4, 5, 6 transfers of this error is not present (it can be shown on the third, but very rarely) If necessary, I can remove the LOG using VagCom I traveled with a laptop and in fact there is no transfer The car goes normally (sometimes there is uneven engine operation at idle, almost imperceptible) Title: Re: Max charge pressure exceeded Post by: nyet on December 20, 2018, 08:22:54 AM Get a log with ME7L and post it.
Don't bother with VCDS. Title: Re: Max charge pressure exceeded Post by: shelev on December 20, 2018, 08:24:32 AM Get a log with ME7L and post it. Don't bother with VCDS. What parameters do I need to write? Title: Re: Max charge pressure exceeded Post by: nyet on December 20, 2018, 08:25:29 AM What parameters do I need to write?

On the Nef stage 2 and stage 2 ++ software, I get an error — the maximum boost pressure is unstable. I checked the intake system with pressure and hoses for the opening of the turbine extensive - everything is fine Excessive increase after 2100 milbar Air leakage was detected after the mass air flow sensor in the corrugation to the Y-pipe and on the vacuum brake booster. I do not know why there could be excess pressure, I registered the logs with the help of VTsDS. Alas, the wire can not contact the registrar ME7 By groups 115-020-003 and 118-032-001 When I changed the engine, I only had the old air filter Crankcase ventilation system Corrugated pipe Y Intercoolers (old engine had the same problem) On other ECU programs, the car is relatively normal.

Title: Re: maximum boost pressure exceeded Post by: shelev on January 30, 2019, 02:51:14 AM I managed to record a few logs
Do not judge strictly, this is my first time using Me7logger I will attach a link to google disk with log files https://drive.google.com/open?id=1BGdx6-IXTvXcasSkq4ydWd-620tsxi3F Title: Re: Max charge pressure exceeded Post by: shelev on January 30, 2019, 03:14:35 AM I managed to record a few logs

You are out of injector and you have heavy knock. Please create one clean log in 3rd or 4th gear from 2000rpm wot into the revlimiter. non of your logfiles is complete didnt have a deeper look into this but is this tuned or stock? would recommend to log it stockwise first. Title: Re: maximum boost pressure exceeded Post by: shelev on January 30, 2019, 06:59:49 AM Yes, I'm a little confused topic, I apologize
I will find a road without congestion and write down a normal log Could you throw me a normal file of a typical profile, otherwise I don’t have all the values in the file that are written in S4wiki Title: Re: maximum boost pressure exceeded Post by: aef on January 30, 2019, 07:38:29 AM https://github.com/nyetwurk/ME7L/blob/master/ecus/8D0907551M_0002%20RAM%20Variables.txt

Title: Re: Max charge pressure exceeded Post by: shelev on January 30, 2019, 09:52:54 AM I think you and I have a misunderstanding because of my not very good knowledge of English

Please get your thoughts in order, tuning requires a bit of discipline and a better attention to detail. I removed the logs on the 3rd transmission gas to the floor to 7000 rpm Evaluate them if I try to take pictures again. Long recorded these journals as we have a frost -42 and I did not dare to start my car in such a cold) Title: Re: Max charge pressure exceeded Post by: nyet on February 11, 2019, 09:55:02 AM I don't see anything obviously wrong in those logs
Title: Re: Max charge pressure exceeded Post by: shelev on February 13, 2019, 02:18:13 AM I don't see anything obviously wrong in those logs I constantly get an error (with it sometimes there is an error on the detonation sensor G66)I tried to change the ECU, I have 8 of them at all. The machine works on the same. If I upload other firmware such as ABT, giac or even my own custom firmware and other people, there are no errors and the boost is always smooth, but I really like the dynamics of the Nefmoto firmware and I would like to keep it. What else can be associated with such problems with excess pressure boost?

My only suggestion is to look through the FR to find under what conditions that error condition is set, and log for those conditions. I will dig through the FR again (time permitting) and try to give you some pointers. Alternately, compare the two files (NEF vs working mod) and look at each change and see what might cause it. You do have quite a bit of overshoot, so you could be hitting DLULS. Pull a bit of IMX and try to get the overshoot under control.

I have such a mistake only on firmware Nef stage 2 and stage 2 ++ I can not understand why this happens with this machine, I have already changed everything for a new one MAF N75 Ignition coils N249 valve ECU temperature sensor boost pressure sensor nothing helps the error gets out basically when you just started the car and in the first hour or two of the trip 98 octane gasoline (constantly) The main place where air leaks in the car is the Maf corrugation (the exit that goes to the injection pump) Title: Re: Max charge pressure exceeded Post by: shelev on February 13, 2019, 12:36:30 PM My only suggestion is to look through the FR to find under what conditions that error condition is set, and log for those conditions.

You do have quite a bit of overshoot, so you could be hitting DLULS. Pull a bit of IMX and try to get the overshoot under control. What do you mean by "FR" I do not quite understand you. The error as I have already said appears arbitrary, mainly on 4-5 gears with low engine speed and up to 3000-3500 rpm. At this time, when I go with VCDS, I observe the increase in pressure up to 2400-2450 milibar in the 115 group. The error manifests itself - you press on the gas and the car gets into an accident, releases the gas and immediately presses - the accident disappears Now I have a new engine from Japan from Audi Allroad with a mileage of 70 thousand kilometers, the old engine was APB (the one with which I bought the car in the USA) It had the same mistake, but I bought a new engine completely assembled with turbines and sensors, and the same thing on it (( From the old motor only remains: Clutch RS4 (Flywheel, basket and disk) Engine wiring ECU (with firmware) Air filter (it was almost new) Spark plug Maf (I have 5 of them) Exhaust RS4 B5 Lambda probes (I bought them new bosch) Spider ventilation system for crankcase gases behind the engine and Valve of the sentiment system that is inserted into the Y-pipe Title: Re: Max charge pressure exceeded Post by: ettla on February 16, 2019, 03:51:22 PM ME7 Documentation

Title: Re: Max charge pressure exceeded Post by: shelev on February 25, 2019, 02:41:21 AM Log MAP sensor voltage. Perhaps it is noisy and/or seeing voltage spikes. I had a broken wiring to it, I restored it (soldered). So I also wrote this parameter to the log, if you look at it through ECUxPlot, you can see everything, but if necessary I can write the log again |
