Wideband reading different at high revs

Post by mickytruelove »

Bit of strange problem,

I am using a innovate lc1 with gauge, wired to the ELD input for full 0-5v.

i have put the correct voltages/lambda settings in and set the voltage offset so the ecu reads the same as the gauge. I had done most the tuning on the street and had went to the dyno to finish up the high revs and high boost parts. I then noticed the AFR reading on the ecu matched the gauge (and dyno wideband) at lower revs and load but when into vtec and WOT the AFR the ecu records is a whole point leaner 13:1 while actually is 12:1.

Is there any common things to check? ELD input ok to use?

Id like to get to the bottom of this so i can record some pulls on the street and make some changes.

Have you removed the resistors as the help file recommends?

nope, just read that now.

I done some searching but cannot find out what those resistors actually do? I will try remove them as the instructions say but would really like to know what effect it is having on ecu.

will annoy me until i understand it.

By them being there it can cause the readings to be skewed.
