now the injectors runs maximum at 39% at maximum boost (7 psi)
didn't know it was an increment %
hks ssqv (I think it's a fake) obviously tested for leaks
my version of O2 clamp
random photos
now boost pressure is 10+ psi (0.7 bar)
Dunno how, but I can reach maximum boost on first gear with that chrubo, really impressed!
whell... It's time to set the spark advance
maybe I will post a video soon

it's happening again
precisely three times in two days, one of these during a 6th gear pull (saw only 200 kph before SHHHHHH)
btw
off topic mode: ON
"hey buddy, look at my new super racing seat"
"cool, can I try it?"
"go ahead!!"
<awful noises while I try entering in a miata with that seat>
"awersome!! compliments "
-back to home
-mobile starts to ring
-see that:
mfw had to buy another mobile: 300€ gone
off topic mode: OFF
have to wait another mounth for rev ms

When I can buy rev ms2 first step must be gm iat sensor with bung right before throttle body and obviously afm removal, but until that I have to read wrong intake temperature (hotter than real)...

I'm running an emanage blue: increment is %, and when I am on boost and low tps and rev, the oem ecu is still on closed loop, trying to reach 14.7 afr.
Also I am running LPG, and this particular O2 clamp do three things:
when on gasoline is a simple O2 clamp (1.1 bar absolute pressure and 2 seconds delay before return real O2 signal) setted to 0.45V
when on LPG a bypass on afm mod. is active (420cc rx8 injectors required afm modification) and when in boost automatically switches to gasoline activating the O2 clamp too and removing afm bypass

compression test today:
cold engine: I couldn't warm up because intake line is at the workshop
wot
without spark plugs, ignition and injection connectors disconnected
very strange results
27 bar average (390 psi)
pic related:
cyl n°1 is 5
cyl n°2 is 6
and so on
after first check battery was low, crank was lower and readings too
but... I've read about 200 psi for a new 1.8 engine: this is almost double pressure!

I know that, but it's the oem sensor, which is impossible to seal against boost pressure.

this little miata is still running very well, but it's time for some cheap improvement:
1.3 bar radiator cap
set of ??? grommets (dunno the name in english)
to do this (thx acedeuce802):
and, last but not least... I have enough money for the rev ms2!!
but I don't have my tune driver anymore... he is in canada for a mounth
Oh, and I'm preparing an ebc with an ALLOFIT button for 12 psi, I hope it will reduce the boost threshold
aaand it's time for a cold air induction, precisely a filter box
worst problem is: I have no time for this hobby

turbo started to whistle when in high boost (10+psi)
I checked for leaks, but all seems right
when I checked for shaft play, I notice a little play, around 0.5-1mm (0.019-0.04 inches)
Is it normal? I don't remember that when I installed it...
