My turbo died, so went and bought hybrid upgrade from local reputable company - TurboSystems.
They did all the work needed. Took and put new turbo.
THE PROBLEM:
With hybrid car CANT get stock boost... it takes AGES i mean ~20secs in 4th gear flooring to get 1,6bar Boost. and 98mm3 of fuel injected.
They said they adjusted geometry control as per manufacturer's specs. But i never heard that hybrid is not able to do at least stock boost! Looks like they failed to calibrate geometry actuator.
Wen i changed VNT maps and added +15% to values then turbo spools faster and so on.. but still pretty hard to get 1,6Bar boost. While stock could pretty fast do 1,8Bar. in matter of seconds.
WTF? I think this is turbo problem not software. If i need to change +15% VNT map this is not the option.. it should not require that much of change. Car with no changes took 13 SECONDS! to get from 1700 rpm to 3100rpm!
Maybe this will give some clue - exhaust after hybrid got MUCH loader! So i guess too much exhaust gas comes with no effect on spool yes? Because turbo should act like silencer in some sence.
I uploaded csv log of my latest "tune". with more then 15% increased VNT map values.
