E85 guys, do you test it?

That has been my only concern about going e85 but after reading and seeing that tester looks like I could control it. Can some one tell me tho, if say E93 like the guy in that thread had will go lean will E75 make the car run rich? I have always wondered that since the less ethanol the less octane right?

I do test mine 90% of the time.

I think that guy is a little bit 'Chicken Little' with his "dangerously lean" comment.

Nick - if u r tuned on a true 85% blend en yes it will run a bit rich if u r down to 70%. It's nothing to be worried about. I asked this of Lund when he was revising my tune.

Well this guy repeatedly tracks his car so hes understandably vigilant.

Yeah IDK if I would worry that much for two reasons. If you aren't on the ragged edge of your tune, shouldn't be a big deal. 2, IDK that if being more ethanol than gas would lean it enough to over come the added octane to cause problems.

Have yet to test any of mine but do plan on getting a tester just for shits n giggles

@Falcon
You trolling, or genuinely interested? I know you're pretty opinionated about ethanol from the E85 thread I started a while back.

In all seriousness, I used to check mine all the time using the graduated cylinder method, but I stopped recently due to the blend never changing out here. I only use one station (Western Convenience) and they're always 85% ethanol... never even switching to the 70% blend in the winter.

I have two AEM widebands and watch them closely all the time. I have a pretty conservative tune as well.

Yes I do periodically. Last batch I got was 90%.
