At last! unfortunately there is nothing that really says anything, other than there is an initial -20% out of the airflow map? but this returns to normal, the duty cycle drops as it should during warm up, although you didn't record for long, but the duration remains the same, are you sure there is no adjustments to the front panel rotary switches?

Sorry Ricky, that airflow adjustment was me changing it back to 0 on the front panel on the first switch. they were all put to the bottom. As you could see it still didnt make any changes from moving it back to 0.

 

Im assuming the injector durations should alter then?? But mine seem to be stuck at 6.7 ms.

Yes Ricky, it is the stock ECU in there at the moment but i have tried my friends ecu before and im certain it had no affect at all and was still running rich HOWEVER, this was when my innovate was playing up and only displaying 7.4 afrs.

 

I will have to try his ECU again one time and check the durations on the e-manage software which is what i should have done before but ddnt know about this at the time.

Well emanage blue uses GSC to save data log files so it should do it automatically, cant understand why yours are LGI maybe the file compression has changed the format.

Did you say that the ECU has been changed? as i am starting to think there may be a problem with the output stage of the injector drivers.

 

I also wonder if it also could be down to the intake temp sensor, but I'm not sure how the ECU behaves if the sensor is faulty.

Honestly I'm going to have to start contributing to E-Manage threads again soon for the good of the community no matter how much it upsets you.

Please feel free Ian, the factual content of what you say has never given me a problem.

Since you where already contributing, i see no reason why you shouldn't continue.

 

I haven't used blue EM for quite a while and had to reload the software to try and display the file, and the first three files wouldn't open, or just fire up the EMU software,

 

I was under the impression that the duty cycle reduced as the std ECU came off warm up correction? but he duration didn't change, which presumably is why it has rich AFRs?

 

For my third answer, dose the N/A have a air temp sensor? and whats you opinion
