My first log, be gentle with me LOL!!

[Mark300zx]

Thanks for the help guys

Are the MAF readings low because I haven't hit the higher end of the rev range, or are they low compared to other LCRs at that rev point, or do you just mean I need a new MAF?

 

[Damoegan]

Poss low due to lower rpm, but we wonte know till you do anoth log

 

[8bit]

Also, log no more than 2 blocks at a time.

Why only log two blocks at a time?

 

[Damoegan]

So that you get a better sample rate...

Cool, thanks

 

[DPJ]

And it makes it a lot easier for us to read / weigh up.

[truCido]

Still MAF readings are a little low, not quite where they should be. The timing pull at peak would go with that as well I guess, its not big timing pull (6 is max you wanna see really) but on a non-remapped LCR I guess I wouldn't wouldn't expect to see any? What fuel do you use in it as well?

 

[Mark300zx]

Thanks for the feedback, it has got tesco 99 in the tank.

 

[slappy_dunbar]

The MAF numbers are fairly close for a K04 boosting less than 1bar. ~165g/s is only a touch shy of the ~175-180 seen typically. Clean the MAF sensor? Pressure test?

 

[Mark300zx]

Thanks for the help bought a new MAF and a nice improvement in performance followed

New logs?

 

[Mark300zx]

Not yet bud, only put it on today, I live in London and finding a clear stretch of road to do logs, is slightly problematic

 

[ChrisGTL]

ok cool

But you can feel a noticable difference in power/perfomance with the new MAF?

Hope you don't mind but i've pinched your peak figures for a little database i'm doing. I'll add your new MAF figures if you do another log.

 

[Mark300zx]

Yes I haven't even given it a good blast and there is a very noticeable difference in power and the smoothness of acceleration, no worries about the database

 

[truCido]

good work

 

[Damoegan]

So the forum to the rescue again then

 

[Mark300zx]

Ok done my first run with the new MAF and although the flow have improved it hasn't been dramatic and I am still getting some timing pull, here is the log!

Some defo timing pul which is bad on a OEM LCRl...How old are the plugs mark?

 

[Mark300zx]

They are about 3 months old and are NGK 7 iridiums, any ideas as to what may be causing this will be appreciated
