once you get all the settings correct i think you will be pleasantly suprised with the noticeable difference in low and mid rpm torque, as well as the engine running much smoother than when it was on gasoline.

 

Actually its true, even with incorrect settings I noticed the car was a lot peppier at low throttle. In 5th and 6th gear there was a noticable increase in power while at cruise and giving it a little more gas.

Guess we'll see what happens on my next tank of e85, sucks that I ran it down to zero bars and filled up with 93 today, haha.

 

If I am understand you guys correctly. I assume that I will have to flip a switch in my engine bay every time I switch blends of e85/gas?

Will I have to make adjustments when I go back to just running gas with no ethanol in it?

 

Someone please correct me if I'm wrong, but won't the ethanol eat thru the seals in your pump/fittings/injectors?

I work for a major auto manufacturer, and I know for a fact that we have some significant parts changes on the assembly of one of our engines, due to making it E85 compatible. I'm not just talking a new computer that will remap fuel settings appropriately...

When I get back in the office next week, I'll check with the guys that are working directly on the project, to make sure I have my info right. But we already talked about it once a few months ago, and I remember this coming up.

These E85 conversion people might be costing a lot of people a lot of money in the long run!

 

believe what you want when it comes to what the auto manufacturers say. However people in Brazil have been running these kits for many years now and their vehicles aren't having any kind of trouble with seals, injectors or any of the other items you listed. Just my 2 cents.

 

no, the conversion kit and the cars ecu make the adjustments automatically. the only adjustments that you have to make are at the time of original install.

 

Well, I tend to trust the people that make decisions on cars that are at the top of the long term reliability lists. But as I said, I will confirm the changes before making any final assumption.

 

here's a good video where a 2000 Chevy Tahoe (not a flex fuel vehicle) is run for like 100,000 miles on e85 and when they tear it down they find even fuel system components are in better shape than when run on regular gas.

any new updates????

 

Its possible your unit is set too rich. So it works ok at low rpm and throttle position, but if you push it the injector is getting pushed past 100% duty cycle probably because the unit is requesting too much fuel.

That would also explain the bad gas mileage.

Get on a dyno with air/fuel and test the different settings.
