peter's jabba'd cupra logs

gazjones · Oct 22, 2006

vag com'd peters car today as it went into limp mode the other day, no fault codes came up and i did a log of actual v requested and a maf i can spot any problems but its different map to mine and different turbo!
there was a big drop off in boost after 5k but was spot on through midrange, anyone have any ideas from thses logs as to why it went into limp mode

cheers!

m0rk · Oct 22, 2006

looks like it can't maintain the boost requested....

heatsoak?

What car is it? Ibiza Cupra mk3?

gazjones · Oct 22, 2006

yes ibiza mk3 custom map running 95 fuel but setup for that. so you think after about 5k it heatsoaks and losses boost due to small smic?

m0rk · Oct 22, 2006

Yes, ain't custom though to 'not' allow for heatsoak.....

what did the inlet temps look like when logging?

anything past about 60C will cause the ECU to pull back, but it shouldn't limp mode it.

what about wastegate duty (118?)

gazjones · Oct 22, 2006

did log all of them but he hit limp mod doing a high speed run the othernight as basically high revs in 5th if i meet up agasin ill log his intake temps and see if they get really hot
cheers mork

cordobabrendy · Oct 22, 2006

big spike from 2600 to 2800 then settles, would it be the spike causing issues?

gazjones · Oct 22, 2006

i know you always get the spike at about that rpm on a graph its a very short spike then settles perfect it weent into limp mod at high rev so wouldnt have thought that would have caused the limp
but thanx for feedback all will be helpfull

cordobabrendy · Oct 22, 2006

I take it the spike is a k03 feature as mine doesnt do it (didnt do it with standard smic nor fmic)

gazjones · Oct 22, 2006

mine does it as well with a ko3s but when ive had it logged by revo dealers they say there will be a spike where that is and they are always right might be a feature of the smaller turbo very fast spool up?

gazjones · Oct 22, 2006

ok will do ill meet up with him again and log the intaketemps and 118 is that wastegate duty does that check how the n75 is working

Bogwoppit · Oct 22, 2006

Thanks for the post Gaz, we will have to do another run

gazjones · Oct 22, 2006

yes just to check the other things but dosent look like there is a problem as such just dont push it that hard but good excuse for a fmic lol

Bogwoppit · Oct 22, 2006

Gaz I did another speed run on the way home on my private track and the car pulled fine with no limp mode this time. Got to similar speeds as my first run and limp mode definately didn't initiate. I will take it steady from now on though.

ibizacupra · Oct 22, 2006

MAF on logged REVO and CC on mk3 cupra I have seen 160+g/s
140odd looks low side to me

Bogwoppit · Oct 22, 2006

The car has still got a standard panel filter but I have smoothed the airbox and fitted a bigger air intake facing backwards in the inner arch as the original.

gazjones · Oct 28, 2006

these are thew logs of intake tmep and wastgate blocks 4 and 118 intake temps dont seem really high but not got a clue about bloke 118 so any input will be good!

The outside air was 17 degrees C during the above log.

cordobabrendy · Oct 28, 2006

60 degrees is actually quite high, with around 17 degrees outside with a fmic you wouldnt see much more than 30-32 degrees, less when not nailing it.

Bogwoppit · Oct 28, 2006

What temperature does the intake need to reach before limp mode is initiated?

cordobabrendy · Oct 28, 2006

to be honest i think you would have to be running very hot as it will just wind back timing otherwise and the car will boost a little less and feel more lethargic, similar to using really bad petrol.
I think boost issues and sensor problems would cause limp mode well before intake temps, some of these cars are used in isreael, egypt,turkey etc.
