MTX-D EThanol Sensor reading high!

Post by mrspades252 »

So Ive recently installed the innovate mtx-d ethanol analyzer and hooked it up to my v1 s300. On the gauge itself shows that I have 10% ethanol (93 octane) but for some odd reason, my laptop shows a higher value at 48%! The analog 0-5v is being wired to b6 (yes i deleted the resistor) and its giving me 0.80v from this wire... i even tried to swap out the ethanol sensor itself just to see if itll rule it out, but no... Can I get help please! I need to get the car tuned as soon as possible!

Ok my gauge is actually reading 19% ethanol at 1.19v, my apologies.. The reason why its at 19% is because I was at the dyno over the weekend and tried to tune on the car on ethanol for nitrous. We couldnt figure out why the software was showing a higher percentage so i dumped 93 gas back into the tank which is why its reading at 19%.

I have reproduced what you have described on the bench and let the software engineer know. I do not know if it is something we will be able to solve in a short time.
