MAF logs help please

[cocadave]

Was just hoping someone in the know could have a look at these and tell me if they're ok or not?

Engine is pd 150 and the run was in 4th gear, thanks for any advice.

It's a cool little boost plotter program that you simply open your log file in and it'll give you a nice little graph like this

 

[cocadave]

Thanks seatman, i'll give it a go

 

[Bondiblu]

The MAF readings are sitting on the Diag limit all the way to 4000rpm so seeing plenty air, means a remapped car with increased boost, and the EGR is constantly closed. Not much more to say from that log. Are you looking for something in particular?

Thanks for the clarification, to be honest i was hoping that the MAF had seen better days and that being a reason why i'm down on power, well not really down on power but maybe why a didn't get a bit more when i had my hybrid mapped,

Do you know what block to log to see how much boost it's producing?

 

[Seatmann]

Group 11 in measuring blocks.


Hey up Bondi, I knew you'd be able to read that log, for the rest of us mere mortals though it's easier with a little line to look at lol

 

[Bondiblu]

A hybrid would explain the high MAF readings and yip block 11 for turbo as seatmann said .

 

[cocadave]

cheers guys, i'll post them up when i get them.

 

[cocadave]

Right then, i've logged block 11 and hopefully it looks a bit clearer than the MAF logs...

any chance of explaining what these results actually mean?
