MHD+ acc. times Ron100E5 vs Ron100E45 vs E40 map.

Hi all,


I have recently acquired the flex fuel system from MHD.

As you can see I have been testing quite a lot yesterday, but to be honest I don’t see much difference between the maps.

I do understand that wheel spin is very much a thing in 0-100km/t, but the 100-200 times did not improve at all, that is a bit surprising to me - what is your experiences?

Stg2 OTS Maps:
Ron100 and pump E5,
Ron100 and added E85 to hit E45
E40 map (with tank full of Ron100 and added E85 to hit E45)

0-100km/t = 0-60mph
100-200km/t = 62-124mph

I would not say I feel a difference, from E5 to E40, this is also a bit of a puzzle to me..

In 100-200km/t I see only 0.4sec improvement from Ron100 pump e5 and dedicated E40 map!



What are you thoughts on the missing performance improvements or am I expecting to much here?

Do you have logs of both E5 and E45?

Nope, what should I log, what would make sense to look at?

This list would be a good start:

So, pretty much all factors, as I see it?

I better get going!

Ps. I even got this, this morning?? (Sensor said e45 on dash)

I'm starting to think the map isn't adjusting for your ethanol level. Which exact map do you have flashed to the car? Are you using the Flex Fuel OTS map?
