You should be able to run B9T9 on a k03s with minimal timing pull. Perhaps the stock fuel pump is struggling? I'm presuming you don't have an LCR one installed?

Yeah I did hear that alot of people run T9, im going to have to find someone with a sps and wack it up and take a few logs, nope standard pump.. I think I will buy a LCR pump next week.
 
The only thing was that I had a fair bit of pull now... if the fuel pump was failing and it was running a bit lean could that cause and extra timing pull?
 
Hi Guys,

I took a few logs 002 020 004 today (I can only do basic logs)

My car doent feel quite right..

Can anyone tell me if anything looks wrong :) cheers

your injectors are max'd after 5700rpm >100% duty cycle, so I would imagine your afr's are starting to run lean then also...

wideband gauge advised or get it confirmed at a dyno with wideband logging ability
when they run lean they will run higher CF's

That would explain it.. it feels like it just doesnt want to rev freely after then.. say this is proven by wideband logging what would you advise to do? would a 4bar pump make any difference? I cant up the injectors because it is only a stage 2 map..
 
on these, the map determins the injector duty cycle.. I believe from airflow... Or hard coded...
its driving too high a duty cycle tho in the map as is..

wideband will confirm if the fuelings actually leaning out or not..

Well it seems very reluctant to go past 6k so say I just assume from duty cycles and that that it is running lean what do you think will resolve this problem?

I have just recently fitted a forge unos and bypassed the n75 (still leaving it plugged in) as Alex from backdraft took a few logs for me and advised me to do so. It had very irratic boost... spiking over 30psi and holding about 9psi.
Obviously that was down to a duff N75 as now with the mbc its fine.. i have set it to spike at about 24 psi.. but now its holding a lot more boost now, between 15-20psi at about 6k (cant remember exactly)
do you think this could be the reason its leaning out?
 
hmmm. not 100% :think:

I would get a working N75 for which the software was written for.. Question if the N75 was'nt cause for the erratic boost and something else was, the mbc has masked its issue.
if its holding boost like that tho, thats a little more then k03s normally do that I've seen

From looking at previous logs revo stage 2 asks the turbo to produce as much boost as possible after a certain rpm (cant remember exactly when) but definitely before 5700rpm meaning the wastegate would be completely closed and the turbo would be working flat out at the point where the injectors are at 100% duty.. so it would make no difference having a mbc or n75..
As for the spike i just set it by feel working up from 20psi.. and got to about 24 psi which to me felt like it was pulling its hardest.. anything more than that and it felt like overboost.

I will have to try and get some boost logs up in the near future.

Just a thaught here.. if i were to put lcr 225 injectors in and run them at 3bar would that possibly work? any overfueling could be taken off using the primary fueling in lemmiwinks or something like that.. or is that just never going to work
 
james i would really be questioning your revo map i can try and get the number of the mapper but as you well know it was kinda doddy set up for water meth when i first got that car might be worth a pop.

Alex did play about with it on the SPS box and only boost and timing is adjustable on the ibiza's.. and being as the n75 is now bypassed i can only adjust timing.. which isnt far off may need increasing a tad.. all stage 2 maps are the same appart from that. I dont think that is the problem..:confused:
 
yer i guess they are just generic maps im stuck here mate my car does the same just stops pulling after 6 maybe its cr turbos lol i just like blaming them for things.
you really have learnt a lot mate hope you get this sorted only thing else might be worth a pop is to put the ngk bk7e plugs back in did you change them?
please stop me if im talking crap lol

Haha yeah i know you do!

The turbo feels really strong though.. boost really hard now.. its deffinately a fueling issue rather than an airflow issue.. which is backed up by the fact the injectors are working flat out at and after 5700rpm..

I am going to buy a lcr fuel pump next week because my one must be working overtime with a 4 bar fpr and 100% idc.

As for the plugs they are exactly the same plugs just iridium versions rather than copper, i did notice all the plugs i took out had the wrong gapping..

there is just too many things it could be its so annoying :(
 
i just got the lcr pump good mod if you going bigger power later on in life. i would say its most likely to be the pump my car was running silly lean with a crap pump. old cars now
what are you future plans im saving for a 350 bhp turbo hehehehehe

Thats what im hopeing .. how much are they about £200?
Good shout your engine is calling for it!.. you thinking about a diff too?
 
Yer 200 from bill badger 5. Yer I'm going to have to get LSD but going to just try it with boost controller first see how it holds the power can't wait got a lot of saving to go :(
 
looking at intake temp i wouldn't run any more advance timing and cf on cylinder 1 in 4th shows that its about at it limit at 5.3 which i think maximum is 6 from my limited knowledge but your logs look good 177 gs sounds about right for a stage 2 revo map
