Hi, Maybe @Adamw can achieve that data! Regards.

Thanks Adam for the Decoder, Overrun fuel cut is configured for a threshold of 5% of AP and 2500 RPM. Map.pclr

Hello, I'm experiencing some strange issues with the overrun fuel cut. During track testing the engine was working well, but sometimes you could feel and hear momentaneous power losses. I checked the data and saw a variable 'Limits Word Flags' which coincides with the overrun fue cut activation. It activates correctly when it is under the setted %AP and over the setted RPM, but sometimes the ECU randomly activates it very shortly. I attach the logfile here. Could someone please explain me this 'Limits Word Flags' variable represents? and what the issue with the overrun fuel cut comes from? Thanks in advance. T8.llg

Hello Vaughan, The thing is I'm unable to save a pc log, I can upload an ecu log instead. Is this okay for you? We don't use turbo in the vehicle, do you know of any safety feature which could affect rpm limit?

Hello, I've experienced a problem using electronic throttle regarding ignition cut. The thing is that the engine works properly while running, but when full throttle is applied, it seems like the ECU is limiting RPMs as you can clearly hear the ignition cut. I've searched for safety features of the electronics throttle but couldn't find nothing related to this, does someone know what can be going on here? Thanks in advance.

Okay! Many thanks, we will have to wait for it then.

In G4+ is not possible, but in G4X?

The thing is that we already developed a map for the staged injection, which is okay but doesn't improve the performance too much. Therfore, we want to study the possibility of improvement in the second stage, by adjusting the injection timing.

Thanks for responding Adam! I explained my issue incorrrectly, sorry. What I would like to achieve is, to have one fuel map for the first stage and one other for the second, this way when the pre-setted RPM are reached and the second stage starts functioning, it does it with a different map while the first stage keeps functioning with its map. Therfore, my issue sums up to how can I configure a different map for each stage. Many thanks!

Hi! We have included an extra ramp of injectors in our prototype's motor and I got to the following issue. I've been searching in the G4+ Configuration and Help section a way to use 2 fuel maps in order to switch between them when the second ramp is active or not, in funciton of the RPM. Does someone have an idea about how to achieve this?

Perfect!! Just what I was looking for, many thanks Adam!

Hi, I was playing around a bit with the time plots and I couldn't find a way to plot the logging data to see the variation of it since it started. I mean, you are able to see the full log in a time plot once you stop logging, but while logging, you can only see a short period of the data. I would like to know if it is possible to have a time plot which shows the whole data logged while pc logging. Thanks in advance!

Okay, many thaks! I'll wait for your confirmation about the sampling frequency

Hi, I'm designing a Data Adcquisition to measure the torque of a motor on a bench and I need to know the sampling frequency of the Analog Input Voltage 0-5V in order to determine the RC filter I want to introduce in the signal which is sent to the ECU. Also, it would be very useful to know if the proper ECU has any internal filters in this pin configuration. Thanks in advance!

Here you have Adam, I had to start with 10% of APPS as it won't even try to start at 0% (2.5% of TPS). It went on idling for about 10 seconds and die, the trig1 error counter went up by 2 at the beginning and 2 more errors when the motor stopped. Also, there was a peak of RPM at the moment it died, just like I commented yesterday. 1234.pclr ETB IDLING.llg
