I have made the decision to opt for a change of fuel - E85 .
OK need fuel pump , FPR , injectors (440's to 625 's) + remap.

Now the hardware I can install and get a fresh tank of E85.
Now I have to get safely to the mappers !
Assuming I will have 625 cc injectors installed -The size determined by a 42% increase in fuel to meet the stoichiometric requirements of E85 .
Will I be ok to drive the car , given my existing map (Link) will not have been altered.

 

I guess you are not based in UK?
How far are you planning to drive without a remap?
Do you have any means of doing any data logging to find out whether you will be running stoichiometric?

 

I remember reading somewhere that E85 doesn't suit Subarus or their fuel systems, might have been in the now defunct Total Impreza.

 

You are correct - I'm in Oz.

Distance maybe 50km's


Yes I can log via PCLink.

 

I wouldn't wory for 30 odd miles.

I've discussed this with my mapper in the past and the car he ran did suffer with fuel leaks after about 12 months but the car was built out of parts so may have been an assembly issue rather than a fuel cause although many of the pumps at the petrol stations over in UK were starting to look very unhealthy after using E85!

I'd consider it if you can get your hands on some injectors and E85 was readily available.

 

I ran my car as low as possible on fuel and then let my mapper change the injectors and fill it up with E85.
