Wideband on D14 only reads 3.xx volts MAX
Got a bit of a problem... My AFX wideband reads 9-16 AFR from 0-5v but my D14 input on my ECU only reads up to 3.xx volts at MAX, and this equates to 14.5ish AFR. It makes it kinda hard to interpret datalogs sometimes. What do I need to do to get ECTune reading my widebands FULL 0-5v input? I have my wideband tab setup properly, and the readings cross over perfectly from the gauge to my datalogs. THANKS!
Well... that kinda sucks. Happen to have a link to the write-up on PGMFI? Well, now that I think about it, howcome the ECU can receive a 4.x volt TPS & MAP signal??? doesnt make much sense. I guess this is because narrowband O2 only uses 0-1v. Can I wire my WB up to a different input? which would be suitable for full 5v operation.1337EJ1 wrote:3.80V max Its normal, ECU can't read more. You can mod you ECU for full 0-5V read, there is topic on pgmfi for that

I have an afx and use EGR D12 with no issues.

yes you can or use serial loggingchepetrueno wrote:sorry to thread jack, but im using a lc1 and couldnt you just reprogram the wb to give 0.1-3.57v ??? would it be good that way

We have had some issues trying this.. There is some sort of restriction on the ELD input. I can't recall exactly what it is at the moment but I am almost 100% sure you will have issues trying to run a 0-5v on ELD. Using EGR required no modifications.98vtec wrote:use eld (D10) and disable ELD in eCtune. no modification needed.

I once investigated the various analog inputs with Calvin. If you follow the directions we put in the eCtune settings about replacing the resistors with 1Mohm units you will be fine. The basic problem is that the original resistors are 1K ohm. Ahaa so what does that mean? Well it means the output of whatever you´re connecting needs to pull anywhere from 2.5 to 5 milliamperes to drive that input. And widebands etc. are not designed to do that. Hence, replace the resistors with something much bigger. Rather than just yanking them out, this will ensure you have at least some protection against ESD and such and it won´t mess with the readings. Done this way, D10 works fantastic. /Allan
