Since having stg1/2 ive noticed that the car sometimes fells really flat. Looking back through some block 118 logs (2K>6k in 4th) The n75 goes from 0% > 99.2% almost instantly.

Heres a bit of a shitty log snippet, but anyway ....

rpm,intake,n75,boost

3400 24 82.4 1930
3600 23 87.5 2160
3840 22 93.3 2260

4280 24 99.2 2190
4480 24 99.2 2120
4640 24 99.2 2060

Fitted a new TIP on friday afternoon, the car seemed to be totally different, but now its back to it usual flat self. I didnt get chance to run any logs in the time it was behaving, but having a search, am I right in saying that this is probably a boost leak somewhere?

I noticed when fittin the TIP that the very bottom metal take off was pretty badly wrapped and you could see a layer of ply's, it appeared to be solid and airtight.
 
Nor me :lol: Do a search for n75 duty - should give you some idea what its doing. Either that or wait till someone with some knowledge replies.
 
Can you post results of block 115 and 118 on the same run please fella? The high duty might be because you've upped the boost beyond the turbos capability.

Logs will help me :)

N75 duty relates to how 'shut' the wastegate is...I.e 99/100 means the wastegate is pegged closed in a desperate attempte to help build boost. Most mappers tend to try and map to 95% duty meaning that the turbo isnt run flat out.

how would he of done that? using a sps3? i dont beleieve hes collecting it until sunday and Grant set the boost at 3 when he had REVO?
 
Ill get 115 and 118 done lunch time and post the results :)

As David said, Grant set my stg1 settings @ 3 all round, stg2 is running b5t6.
 
saying that matt has just had stage 2 so may of had boost turned back up by grant when he was there?
 
i assume youve had a remap? i would expect MAF to be a little higher if its had a remap, mine is 153 max and mines std
 
cuprasteve correct me if im wrong but dont you have a leon 225? if so your MAF readings will obviously be around the 150 mark as you have 225BHP!
 
nope its just a cupra 180 have got the logs sumwhere if u want lol? im not convinced by that bhp calc thing from your maf
 
oh i forgot i logged some guys cupra yesterday too 180 model, that was pulling 149 for maf and agains its totally std
