Dual fuel mappings Help pleas!! I'm new!!

Post by MertensToon »

Hi,

I'm Toon Mertens. I'm from Belgium and I'm new on this forum.

I'm starting with a tunerpro project.

I'm going to study in France next year and I would like to rune my car (BMW 316TI) on bio-ethanol. Now the problem is that there are no bio-ethanol fuel stations in Belgium so I would like to put a dual fuel, ignition map in my ECU.

Is this possible with tunerpro? Can I make something to do this? With a button or something?

I have a bit of experience with megasquirt but this thing I would like to make with my Original ECU.

I Hope somebody can help me?
Kind Regards
Mertens Toon

if you already have an xdf, you much easyer can adapt ignition, fuel (very important, because you need up to ~40% more E85 than gas), startenrichment....


the easyest way would be, to use a chip on which you can make a hardware-bank-switching. one part of the chip for gas (fuel), the other for e85

for example:
0-7FFFh E85, 8000h-FFFFh fuel. you could realize this with a 27C512.
you have to switch the adressbit 15 by hardware onthe 27C512

I don't know, what kind of chip your ecu is using :?:

falls du deutsch verstehst, ich täte mich mit dem erklärbär leichter :D

the harder way is to reassemble and reprogramm the ecu to be a real flexfuel.....there TP isn't helpful.
if you can programm assembler, and you know IDA and NoIce, fine!

have you already adapted ignition and fuelmap,'choke' and so on for E85?
