that's not bad for a k03 ibiza in 3rd - a little low, but not terminal

What mods do you have done?

 

[DPJ]

Mark, don't you think that the 203 g/s at 4720 in the other run is a sign somethings not right with that MAF?

 

[m0rk]

or the run.....

the 3rd run is the only one consistant with what I'd expect to see - wondered if the others were part throttle etc / on off

 

[ibizacupra]

erratic MAf..

 

[r8byb]

Others were defo flat to the floor 100% cause i made sure..

Plus letting off the throttle wouldnt suddnely give 203g/s would it ? I had quite a constant 200g/s when SUperCUpra off here did a log for me.

Im full stage 2, forge everything, n249 bypass, blueflame turbo back, bmc filter, REvo stage 2.

 

[ibizacupra]

it, as has been said a few times already, not posisble for a k03 to flow that qty of air... and your own logs now are at a very much lower (more realistic) airflow, so "erratic" is still the word I would use to describe it.

 

[r8byb]

The logs were all done on the same night, on the same stretch of road, only did that one in 3rd though, all others were done in 4th, 3 up if that makes any diffrence :| lol

Anyone got logs of a stage 2 ibiza ona ko3 to show me what a good log should look like ?
