Since I'm still learning how to tune this makes it really hard for me as well. For instance. Last week the Evom post said there was an E85 station in long beach. Needless to say this was false and I had to fill up with pump gas. The big problem was I had to fill up with pump gas with 2.5 gal of e85 in my tank because I drove over 1.3 hours before I saw my first gas station and I was virtually on rempty. This option motivates me to tune tremendously. I hate draining my tank then having to dispose the extra fuel I have. I also don't think my tunes are up to par so it makes it even worse when I have mixed fuel(I don't drive the car in boost at all when I do).

 

Hi guys,

Unfortunately it seems to be bad news for flex fuel patch.

Last time I have been in contact with donner was about two months ago. The patch has never went out to public as far as I know and now it seems that the only place you can get it is commercial rally shop in Finland who sells flex fuel conversion for Evos (http://www.printsport.fi/kauppa/prod...kqhmsbro2c6247). They also don't give you the XML and there are only a few dyno shops that can do the mapping if stock maps are not good for you.

Last time I was in contact with donner I asked several times if the patch is commercial or free to distribute but never got answer for that question. I'm still waiting, if you are reading this...

I'm very sorry guys that I have wrote some messages "promoting" this and I'm very upset how this turned out in the end. I always had the impression that this patch/ROM will be freely distributed, otherwise I would never have put any of my time testing and giving development help to it

I hope somebody would have time and skills to write a free version if things don't change with this. I'm happy to help and I can even write a document to describing the operation of the patch if needed to help the work provided that it will never be used commercially anywhere.

 

Hello,

Anyone from US or UK for this job ?

ast- :will help you out best he can and all of us get huge benefits from this.

Request :

HC Coders needed !!

 

I wonder what that black box is?

 

Converter for Flexfuel sensor. Makes data of fuelmixture for ECU.

If im understood correctly.

 

The ECU has to know what to do with the ethanol content signal though. Do they advertise a special ROM for the ECU?

 

Yes there is special rom.

For people who are interested about status of this patch, at this moment I prefer watching my beautiful baby girl to learn smiling than coding. This does not mean development is over (actually far from that) but I just don't have time for this like I used to have and porting code to other roms takes more time and there is also other related things to test. If someone is not happy with this and does not understand that family overrides hobbies (and of course want this patch right now) I recommend you find some time from your life and start learning how to do this on your own With that said, one more 8859 tester needed in the near future (unfortunately with unconfirmed schedule and I expect tuning experience like with 9653).

 

I hope if it's using a Tephra rom as a base he is getting some kick backs...

 

Yes donner's ROM in the kit that Printsport sells is using Tephra V7 base.

Those who asked about the black box. It is PIC microcontroller based frequency to voltage converter similar to Zeitronix ECA but without display. So ethanol content information is fed to the ECU as analog voltage signal.

 

My own implementation is now available for Evo 8 ECU (96530706)

Live!!!

 

any movement on this, I know this is a super old thread by evo IX and X guys are certainly interested - thanks everyone

 

Any updates? FiTronic system is an option but I'd rather donate and keep it open source!

 

I think its been 6 years since I started this thread and no progress. Pretty bad. I know I can do it, but I'm so dedicated to running full time E85, its just never become a priority.
