d16z6 supercharged weird behaviour at 1/4 throttle
d16z6 supercharged weird behaviour at 1/4 throttle
hello, having some weird problems
setup:
93 del sol with d16z6
jackson racing supercharger 6psi pulley
rc440 injectors
hondata s300
innovate mtx-l wideband & gauge (powered with fused wire directly from the battery, grounded to the firewall, like the ecu, connected to hondata on D10 ELD)
after i get off the gas and keep the throttle at about 1/4 the gauge jumps up and down from full lean to rich and the car is all over the place
(the car runs on open loop, it seems to be still reading the wideband)
it only does this after i get off the gas and keep the throttle at 1/4
you can see this behavior straight away in the recorded log (attached)
i also attached the tune file
sorry for my bad English :D
thanks
alex

Re: d16z6 supercharged weird behaviour at 1/4 throttle
Has this been properly tuned on the dyno?
Re: d16z6 supercharged weird behaviour at 1/4 throttle
not on the dyno, tuned by a pro

Re: d16z6 supercharged weird behaviour at 1/4 throttle
this behavior started about 2 weeks ago, worked fine for almost one year before

Re: d16z6 supercharged weird behaviour at 1/4 throttle
Has anything recently been changed on the vehicle?
Re: d16z6 supercharged weird behaviour at 1/4 throttle
no, nothing
just oil :D

Re: d16z6 supercharged weird behaviour at 1/4 throttle
It looks like it may be a problem with the wideband as it is jumping pretty much at all times. It could be the sensor or the controller itself.
Re: d16z6 supercharged weird behaviour at 1/4 throttle
hm, probably the controller as i changed the sensor already some time ago
should i remove the connection to hondata and use open loop?

Re: d16z6 supercharged weird behaviour at 1/4 throttle
You could try it.
Re: d16z6 supercharged weird behaviour at 1/4 throttle
you were right
in open loop with the wideband disconnected from hondata the car runs fine
any suggestions for a reliable wideband brand and model (i won t buy innovate again) for closed loop operation?
is it worth it or should i just leave it in open loop? (daily driven car)
thanks

Re: d16z6 supercharged weird behaviour at 1/4 throttle
I would recommend the PLX Devices widebands as they are very reliable.
You will get better economy with it in closed loop.

Re: d16z6 supercharged weird behaviour at 1/4 throttle
PLX gauge and sensor installed, problem solved.
old issue still there though
i get an o2 cel (code 1) almost every day, most of the time during deceleration from 4000-5000 rpm, car goes into limp mode (4000 rpm limit)
if i turn off the engine and restart it cel remains off and does not come back on that day
it seems to happen only under closed loop operation
was the same with my old gauge and sensor from innovate

Re: d16z6 supercharged weird behaviour at 1/4 throttle
How exactly do you have the wideband connected?
Re: d16z6 supercharged weird behaviour at 1/4 throttle
power: fused wire directly from the battery, grounded to the firewall
D10 ELD connection to the ecu

got it a couple of times during overtakes...
