Hondata

Hi, i'm from spain, sorry if i write bad.
The ECU is a p28 of a d16z9 and i'm running a b16a2 with a usdm-p30 map.
In the closed loop option, in the parameters of the smanager, when i select the "closed loop (wideband signal) voltage..." the car runs fine. The problem i have is that after a certain period of time (or engine temperature, i don't know...) it seems like it runs in open loop and at idle i see on the afr gauge 13's 12's...
I don't know why it changes from closed loop to open loop when i selct this option ("wideband signal...") after a time...
The ELD is disabled and when i select the "closed loop narrowband signal" option in closed loop parameters the cars hasn't got this problem, it works fine all the time.

Anybody can help me??

Ciao!!

The hondata is a V2 and on the box i see writed the ref. 23528.
It was bought 1 month ago more or less.

Th car is a 1994 civic e5g with a b16a2 (eg6) engine swap. (plug and play).

The calibration is the same that comes with the stock usdm-p30 map. it isn't modified.

please post the calibration you are using as well as a datalog showingthe problem.

The problem is very simple.
In the closed loop option, in the parameters of the smanager, when i select "closed loop (wideband signal) voltage..." the car runs fine and works in closed loop perfectly. The problem i have (i don't know if it's a problem) is that after a certain period of time it runs in open loop and at idle i see on the afr gauge 13's 12's...
I don't know why it changes from closed loop to open loop when i select this option --> (closed loop "wideband signal...") after a time... and i don't know if this is normal or if the wideband signal is only for running in open loop.... or....

P.s. If i select the closed loop option, but narrowband signal, i haven't got this problem..

A datalog will give information to solve my question...???

Yes, it helps us see exactly what is happening and what may be causing it in the calibration.

ok, as soon as i can i'll do a datalog..
thanks
