If measured as kPa, doesn't that include atmospheric pressure or like a MAP sensor - 300kpa only measures 2 bar of boost?

No idea, wish i had measured the stock fuel regulator pressure before rebuilding fuel lines.
Lean issue probably because of head porting?, checked leaks several times and cant find any more, adjusted +20 on whole fuel map and it started to run alot better.
Driving van into emissions test tomorrow, if its a pass, next mot.
Kinda starting to want this one finished as im building 4 project cars at once atm
Emissions were a solid pass now. IIRC CO was 6% and HC 2000+ previously.
MOT passed aswell today. Next mot in 2025 in 2 year intervals for now since van is now 40+ year old.
Going to drive some ~1000km before going to rolling road for re-mapping.
I thought it was twice before . . . . . . then you start playing / modifying it again ! ! !Originally Posted by Works

Yeah, i admit being mentally ill. Just cant leave anything be unmodified and my projects are NEVER finished.
After struggling with neverending battle with sump leaking oil (i have drained it 5 times, swapped 2 new gaskets, glued the gasket top and under etc. and still its leaking a bit from rear.)
Still managed to get ~500 break in km. without bigger issues before todays mapping/dyno session:
Graphs are a mess, wrong settings were on.
Got 236ps/300nm. 250ps would have been possible, but after two pulls clutch started to slip, then it was game over...
Also need better fuel pump aswell? Duty cycle was almost 100% which i dont remember being an issue last time, had same injectors then.
Going to drive this as is for now, engine out in winter and fix clutch issue.
Few months of driving and again trouble.
Drivers side rear wheel bearing and hub nut broke few weeks ago, took a bit of effort to find new ones but managed to find replacement parts.
Then sigh... oil leaks vol.7698654 more on rear on the engine:
And engine started to run rich again. Idles around 12-13 AFR and on cruise speeds just lightly opening throttlebody, AFR goes to 10.
Seems like spark plugs on cyl.3 totally black: (1 on right)
Noticed some odd readings on IAT sensor, ordered cosworth yb sensor + new coil pack.
Installed new iat sensor, calibrated both iat and clt sensors. Reflashed ecu. (iat doesnt bounce anymore like it did before.)
Installed new coil pack.
Checked & cleaned spark plugs.
Tested compression:
Cyl1=8.9
Cyl2=8.9
Cyl3=9.0
Cyl4=8.5
After engine is warmed up it still idles around 11.8 AFR
Giving some throttle it still feels like one cyl is misfiring on lower rpms
