lc-1 titania simulation
hay people,
I have done some new mods so I just finished up a fresh tune, 324hp at the four wheels form my hnu13 sr20det
enyway with oxygen is turned off or unplugged afr are very close to target afr ,when I plugged oxygen sensor back in ( skinny o2 titania type) It started to f@#k things up, it started leaning out far to much it low load and idle like down to 16.5afr car gets a bit jumpy and ruff.
so I would like to use my lc1's yellow wire to ecu but I carnt find the volt output of the skinny titania sensor
I have watch my stock(maybe broken)sensor reading .39v-1.39v inside nistune
0.1v-1.1v for the fatty
?.?v-?.?v for the skinny
can someone please help

Re: lc-1 titania simulation
What ECU? Do you have the O2 min / max voltage ranges displayed in Nistune for your particular ECU?
Could try about 0.1 volt above and below these values (put these values into logworks for the simulated output)

1E000 with s13 board, 1E000 bin tuned
snap, mybad, yer I can see in the consult gauges that 1.5v is the max
I read in a Nissan fsm for gtir's that they use a range of 0v- 1.5v so its confirmed.
thanks

Re: lc-1 titania simulation
I had a quick check of the SR20DET code but not sure on the voltage values for rich/lean
I see several references to addresses that the O2 voltage is checked against, but not similar to the other ECU

Re: lc-1 titania simulation
1.5v worked fine.
so its drag racing time now, is there launch control for my ecu 1E000?
I just would like to limit the revs so I don't over rev and blow another awd box!! I run semi slicks so its not to limit wheel spin its for longevity of the box and replication of times
or can I just use the safety rev limiter speedo-0 fuel cut?
I would like to stand on the gas revs get held at lets say 4000rpm I drop the clutch all hell breaks loose with no limits

Re: lc-1 titania simulation
No LC for this model. Not a widely used model
You could try the safety limiter until the vehicle starts moving...

Re: lc-1 titania simulation
ok will try that for now,
there is a LC for s13 tho a? u13 and s13 have the same address file. same every thing just apart for the distributor.
my daughterboard has s13 on it
i was thinking that i just needed send in my ecu for a reflash to my older board and done , i guess i am all wrong here
is it because of the distributor?

Re: lc-1 titania simulation
Different ECU code between the two. Even though the same definitions (like RNN14 which is distributor, different ECU code)
I dont think S13 ECU code would work in U13 ECU (have not tried)

Re: lc-1 titania simulation
code, thanks i see
i mite have to look at trying to wire up 54c ecu moving forward then

Re: lc-1 titania simulation
I think that should work fine
