Is it possible to have two maps and go from E85 to 91-94 octane just by switching maps? There is only one gas station that offers E85, wich is 10-15 minutes from my house. If I go on a trip with my car I wont be able to find other ones. There are only 2 E85 stations in Ottawa and one or 2 others in canada (guelph)

I guess if it is possible I would need the cobb ap or something?

 

What size injector's do you have. E85 is some thick stuff.

 

I would get the necessary harware like 1000cc injectors, fuel pump and tunes for both maps.

 

I know you have to get them dialed in. I might consider E85. But considering the scarcity of E85 especially on road trips it would be nice to have a dual setup. Wouldn't want to end up on the side of the road and have a Texas Chainsaw event happen to me.

 

LOL Yeah! Thats why I want to be sure before I proceed with this.

 

If it is possible, I will probably have one of the only RA's in Canada with E85 :P

 

What mods do you have currently?

 

Drop-in air filter and GST 91 oct tune.

 

Maybe you should do some other mods then this. I think its about bang for your buck and maybe at this point E85 might not serve to best. Tuning is very expensive, well at least for a good one anyway. Maybe drop an exhaust, cold-air intake to go with that filter. Then maybe an exhaust manifold. Then boost the bish, then get E85.

For sure, this is just the begining of my mods, I just want to know if both tunes can work.

 

If you want to switch map you'll either need and AccessPort or a Tactrix Cable+Laptop.

Also, from what I understand you need to run MUCH richer with E85 compared to normal pump gaz to achieve proper combustion (someone correct me if I'm wrong). That means, if you thought 93 octane was expensive you're going to be surprised.

As proposed above, start with more basic mods (intercooler, exhaust, BPV, bigger turbo, etc...)

Once you maxed out the potential of those mods then it would be time to go with E85.

But at that point you'll probably have maxed out your transmission torque tolerance and will need to put a LOTS of money there...

 

I'm changing jobs soon like I said the other day, so money will be less of an issue now
Thanks for answering my question Buddy.

 

Yeah 94 octane was 1,34$/litre! E85 I dont know yet, thats why I want 2 maps.

 

I think E85 would be a little cheaper but you need to much more of it in your mix. For N/A car with normal pump gaz, the target AFR is 14.7 but with E85, it's something like 9.76.

That means, for the same amount of air you put approximately 50% more fuel...

 

Yes E85 is 85% alcohol and 15% gasoline, with a proper tune and appropriate parts it will make more power then normal 91-94 octane..
