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!

Post the calibration as well as a datalog showing the issue.

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.

Does the value on your gauge move at all? Is it displaying just a number in the format XX.X, or is it actually displaying "E10"? If it' showing E10, that isn't the ethanol content - that's an error code that the gauge is not reading the sensor correctly. Confusing...I know.

The gauge is perfectly fine, the value does move up and down.. ive even tried 2 different sensors and another MTX-D analyzer from my other car and its still doing the same thng.. hey hondata can you send me 3-4 past previous so i can get this thing tuned?

You cannot use the previous version with the updated firmware.

I don't have an ETA at this time. This is now in the hands of the software engineers.

This has been fixed and we will do a release tomorrow. The display of the ethanol content in SManager was 2.5 times the actual ethanol content, but the operation of the ECU and S300 was correct. So there's no change to the operation of the vehicle; only the sensor value in SManager datalogging.

Was this also an issue with flashpro manager? I’m having the same issue on my 07 fg2. Just wired in the mtx-d and it’s reading 16 on fpm and my gauge is at 10.3-10.4.
