You are definitely right. Though I’m not that worried about the lag since I measured the receiver’s side impedance to adapt the capacitor (1uF) in order have a reasonable response time.

I’m still trying to solve my issue. I’m considering this option to allow me to enjoy my car... I’m planning on a trip to the ring next September !

Next step is to dismount/remount all the connectors...

Thanks !

Did you inspect the front and back of the connector? Could be a bad contact or crimp.

update :

Redid some of the welds on the board, added a ground on the E% sensor side, no luck

Since there are much more drops occurring for the 1st 2 min after a cold start, I checked my fuel pump.
Car has 30k, with 20 on ethanol, and my pre-pump filter looked like this :



So replacing it immediately jumped on top of todo list...

Did not dismounted/remounted all the connectors yet.

Wait, what's going on here? Has the fuel been dirty? Is this an issue with ethanol?

I guess... and it might disturb fuel feeding and ethanol content reading (again, just a -wild- guess...)

I imagine ethanol cleans the fuel stations system pretty good and we get the gunk in our car. Other possibility (the super scary one ^^) is that it’s the car fuel system that’s being eaten by the ethanol !

Its likely contaminated fuel\e85 or fuel additives



Ive got over 6 years and 80,000 km on e85 no issues with fuel system or ethanol readings
