Default RSX and E85

I am planning on getting an E85 kit for my Acura RSX Type-S. Simular to the ones sold here. http://www.change2e85.com

I know I can use it and not have issues. My question is does anyone know if I got the Hondata IMG for my car, if the car and kit would still compensate for the E85 and not run to lean?

have you tried asking about this on clubrsx.com? You'd probably have a better chance of getting it answered over there.

True but I was curious if the local guys had any ideas.

Does anyone run E85 in their RSX?

Plenty of guys in here have been running it with good and bad side effects. I can only hope they take a few minutes of their time to help ya out and guide ya in the right direction.

Yea that would be great. I'm really curious what the bad side effects are. The kit makes it so you don't need a tune or new injectors. I am however worried about the rare possibility of components failing. I am also curious about the Hondata image if it would compensate properly still. Don't want to ruin my car by running it to lean.

Your best bet is to PM one of our members in here (deadmoans) from wrenches automotive. They have a dyno and a tuner that have worked with folks using E85. They could easy tell you the good and bad......just make sure you specify what you already about the fuel change so you dont get a full lesson on it...LOL they can handle the rest.

Good luck man

Is that Brian or Chad? Maybe I will just talk to them in person. I'm sure they will hate on the fact I want to use a kit. lol

I am currently running E85 in my RSX. I will say that you will need bigger injectors and KPRO if you don't already have it. I am not to sure about that coversion kit, though as I have not heard of anyone using it on their RSX. So far the car has been running great even though it is not fully tuned yet.

Thank you for your comment. I don't think I want to go that route due to how much it will cost. I would much rather put my money into my S2000.

If the conversion kit won't work I will probably not worry about E85.

Does any part of the fuel system have to be replaced in a Honda due to the caustic effect of E85?

Ok, first off the "FFI" that they are referring to in the link you posted, after just skimming the instructions, I would say this is basically an "FMU" to up the duty cycle of the fuel injectors, since E85 requires approximately 33% more fuel than standard pump gas. So therefore you need to up the flow of the injectors, now that raises a question. How much can the stock injectors take? Don't know, also don't know what percentage the stock injectors will take.

Let's just say for arguement sake, that this conversion kit bumps the duty cycle of the stock injectors to 90% to accomodate the requirement for more fuel. Now how long will those injectors last running at 90% of their maximum? Don't know. What I do know is that I would have no issue with running a quality aftermarket injector like RC or FIC at that rate, in fact, I would say those can even take more. So bottom line, need to find out what the stock injectors will take.

One possibility of a side effect is the increase in moisture in the engine from E85. I'm not sure if I'm full of shit with this, but I've seen catch cans full of moisture that smelled heavily of fuel. The solution......change the oil more frequently.

Yes e85 does generate more moisture and also will thin out your oil a little faster. Depending on your planned use for the car, switching engine oil to a regular or synthetic meant for diesels would be a good idea. Rotella T has a higher zinc content meant to slow the breakdown of oil by methanol/ethanol based fuels.

The kit doesn't make the injectors work harder. It actually has them open twice instead of once to deliver more fuel. Then the computer compensates for the rich mixture by giving shorter fuel bursts.
