finally every problem has its solution the problem was the spark plugs They were changed before the engine was built but not after. By continuing to think, the conclusion has been reached that when the piston rings dilated, they let oil pass into the chamber without burning, which made it ''pearl'' as they say here in my country in the spark plug, affecting the jump of the electric arc since the unburned oil settled on the electrode randomly. the synchronization fault that even caused cylinders to fire out of time was due to the fact that the m3 e30 needed a spark plug extension. In the case of insulating this extension with silicone, as one might think is the best option, it causes an electric arc to break towards the ground of the coil, meaning that if for any reason the spark plug is left with oil deposits, an electric arc jumps from the spark plug housing to the coil housing and induces a false current jump, of very little amperage but enough to make a cylinder explode. This is solved by not protecting the spark plug extension. thanks to everyone!

more checks today - the fault is that cylinder nº4 does not explode reviewed: - trigger signal OK without faults -compression test OK - coil replaced by another, same fault - coil when the engine is running, it is changed for another with a spark plug and makes the spark jump - revised itb's, especially cylinder nº4 where the servo intake has been well sealed - Completely revised 12v power supply, resistor box (5.3OHM wired without connecting injectors for each one). - Continuity from the link ecu to the correct injector, all the wiring was working for months without flry cable problems Does anyone have an idea what could be going on?

In the registry the problem is present all the time but it is greatly accentuated when you exceed 15-20% the tps and the rpm begin to rise The mixture is not the best since the last thing I do is change the m3 e30 evo2 injectors for the original ones to rule out any open injector and simply change the master fuel to be able to test, having the same fault. It is as if the ignition of more than one cylinder was cut randomly It's very strange

Hello everyone, I am writing to you because I am going crazy to solve a fault in this car A year or so ago we installed a g4x ecu with various modifications which has been working very well. The car has run 2 rallies without any problem and is also used on the road. About 4 months ago it started failing overnight and there is no way to detect the failure, it seems like a random cylinder fails. Things we have tried: -another ecu link g4x -other injectors -another resistor box -other coils (r8 cop) -spark plugs changed -check wiring and new gnd -checked fuel pump and pre-pump -tested pressure regulator -the engine was rebuilt completely thinking that a valve was left open or that there was a failure in a ring since sometimes the dipstick had been pulled out of the oil (although it worked well) and we thought it convenient to do it to rule out an air intake and that with something else After 300,000 km of the stock engine, it had to be tuned The failure only occurs from 50-60 degrees when the engine starts to be hot, when cold it never fails. No trigger failures are seen and the signal is always good with no error counts and on the oscilloscope everything looks ok We do not know what else to look at or what it could be since we are running out of where to look, I am attaching a log (being larger than 4mb I had to upload it to another platform) if someone can help me with this problem. If the activation test is done, all the injectors work as well as the coils. Thanks https://mega.nz/file/ygI0kZbb#iSGNpUhGM5PZgKNSGx8BVY4rNp01x99WttoHu79keEA

good morning I was wondering if it would be possible to control this motor with some solution other than thunder. the problem is that you do not want wasted spark so you would need to have direct spark could you use two storm in parallel? would there be any other problem? Thank you!

I attach an image of my times for the coils The car has been working very well for months, but just like that it has started to give faults (only when hot) that seem to ignite and above all it happens with little engine load, in the upper zone it is practically perfect looking at the afr the mixture has become very poor I have looked at compressions in addition to checking that the same lambda and sensors do not fail and everything seems correct so I suspect that it may come from the coils have you had a lot of problems with these coils?

Hi! I have installed some ngk u5014 coils that I suspect that some of them are failing me only hot sometimes Is there any possibility of logging each ignition coil? If I do a test with the car stopped, they seem to work well but I have suspicions that something is wrong somewhere Thank you

I have finally fixed the problem with a cherry red hall sensor with a bespoke bracket seems to be working fine seems to be working smoothly with the e36 60-2 flywheel with a gap of 1.5mm Regarding the rpm count, I tried a booster with a transistor but this has not worked, the only thing that has worked is the photograph that I have previously attached with the coil of a relay

Hello I've had an electronic with link g4 + for a while Some bosch orange injectors are installed and out of curiosity I have looked at the dead time injector and it does not correspond at all with what I have on the map would changing the injector dead time to the one provided by bosch change the fuel setting a lot? or just a little tweaking would fix it can there be much difference between two different dead times? Thank you

thanks for your help I just verified what it says and you are absolutely right! I have adjusted the gap from 0.5mm to 1.5mm with no apparent changes (perhaps in 0.5mm it failed a little less) so I will try to make a more robust support if I have the failure, it must be with the vibrations of starting it moves the sensor. I will keep you informed of how I solve the problem Thank you

thank you attached the map and the log It gives me the feeling that there is some fault in the trigger but I can't see it, it tries to start even sometimes it lasts for 2-3 seconds but the rpm is dropping as if it lost the signal 323i BMW base.pclx TriggerScopeLog.llgx

thanks I'm trying to adjust the ignition but I find that sometimes the light strobe works and sometimes it doesn't I have looked at the trigger and during the adjustment I see small errors in the error counter between 1 and 3 I have attached the capture if anyone can know what it may be I am using the modified flywheel from a bmw e36 60-2 with the hall sensor from a z3 Thank you 4cc3e782-9d48-46f3-ad06-455e0d98ccc7.jfif 33f97495-3f62-4828-9732-3a9e917f316f.jfif

After a while I am trying to start up and finishing configuring some sensor I was wondering if it is normal for a fuel pump to appear in red (no faults). The pump seems to be working normally Thanks

just completing a few missing wiring things I see that the instrument cluster seems to work for a coil negative signal Has anyone come across this problem? being a k-jetronic engine I think I may have problems with the tacho signal Has anyone come across this problem? with the attached scheme could you solve the problem?

Thanks!
