Next week end i will raise the boost to 1.5 bar and will do a new datalog

 

it would be better to post a photo of the files rather then a zip file which could contain virus's more people would look at it.

 

I tried but it didnt work!

 

Here i print screen captured it for ya

 

Thank you ,how did you find the logs?

 

im no expert on them and it is a bit hard to dig through the long files

its easier to read single run data then partial throttle data and a run in the middle.

and off the top of my head i cant remember the calulation to convert the decimal signal value to AFR so ill just stay quiet

 

To calculate the AFR you just multiply the lambda value by 14.7
per example 0.8 times 14.7=11.76

 

Get the logs looked at..... seems like she pulling timing and going rich to protect itself...
what gas you using...

 

+1 to Markski. The timing angles are all over the place, and the AFR's seem very low in several places. I'd strongly advise you to send these logs to your tuner before increasing the boost. You might consider doing a run up from 2000 to redline in 3rd or 4th gear, also logging injector time. To make it easier to look at, perhaps you could hide most of the lines of data and export as a pdf.

 

Agreed.

I'd recommend reducing boost to .8 or .9 BAR (EBC turned off) and getting some more files to compare to. That way, we'll be able to see how your tune should look when higher boost is removed from the equation.

I'd also not recommend running the car at 1.3 BAR any more until your tuner get's a chance to review your data.

 

Now i am confused my tuner saw the logs and said the logs looks good

 

Okay then.

 

what should be the best value of ignition timing between 5500 and 7000RPM?Thanks

 

Ali, send those over again if you have any concerns. You are running 98 RON/93 US octane correct?

Best,
Neil

 

This will be different for every car and every set up! Work with your tuner on answering this question... in general they will be the only one that can accurately answer.
