Hondata

Well i setup my base map for my car and got it to idle around 1500rpm at around 14-15 a/f. here's the problem i ran into. with the car fully warmed up and idleing the a/f ratio would jump to 17-19 i blip the throttle and it goes back down to 14-15. any ideas on why this would happen. also it appears i can't build any boost. and for some reason around 5k rpm's it studders and the a/f seems to be on par. another thing i noticed is while applying full throttle i watched my autometer boost gauge rise up to 5psi but my datalogs showed the highest it got was -3.5in :?:

setup goes as follows:
built h23a1 10:1 cr
t3/t67 .63ar
1000cc injectors
255lph pump
a/w intercooler
M&W pro-10

It sounds like you are running in closed loop usign the wideband. How do you have everything wired, what inputs and outputs are you using on the wideband and ecu? What Wideband are you using?

its a plx m300. i wired it like the instructions said....

white signal output wire of the plx to o2 signal input.
and a 1k ohm resistor between 12v heater and heater ground.

The instructions specifically state you cannot run in closed loop if you input the wideband signal into the ECU's O2 input.

Reread the instructions: http://www.hondata.com/techplxwiring.html

so in parameter, just unclick closed loop operation and i should be fine?

and btw, i was actually going off the plx instructions that came with the device not yours, as i installed this prior to running hondata

It is recommended to run in closed loop. I would highly recommend following the instructions posted on our website and wire it with the Wideband input going into the ELD and the narrowband going into the O2 input of the ecu.

excuse my ignorance but what is eld?

ELD is the electrical load detector....it is an input on the ecu.
