Thread: E85 afr

Is there a generally accepted "E85 How to:" that we can follow? How does the steel gas tank and the 98'-02' fuel system stand up to the stuff?

There are several threads on this forum which include most of the info you'd need to switch over to E85. I haven't had issues with my gas tank yet, but it is likely a good idea to change out the filter before you switch over, and then monitor it on occasion just to make sure it doesn't get clogged up. I have been running E85 for around 2 months now and haven't had issues yet (that I know of). haven't changed the fuel filter since changing it right before the "switch over" either.

How did you do it? Give us the short and sweet version. What tables need attention?

I feel like I could just open up the injector scale by 30% and be in the ballpark. I just cannot picture all of the consequences that will likely come from other tables.

How do you like it? Did you drop a pulley or raise timing? Have you been to the dyno?

I have a 1999 also (The Best year IMHO). With a 2007 cammed L32, a 2005 transmission, a 2003 PCM and the original 1999 fuel system and engine electrical. And she sets no codes and purrs like a kitty cat.

Ha, where to begin!

That is a short thread I put together on changing over and what can be addressed in the tune. A correction to the timing tables section: I would stick with stock timing and not add ignition advance personally. That has worked best for me and others have attested to the same thing.

I got rid of a TON of KR (like 9* of KR... no joke) dropped a few pulley sizes as well

Not yet but after I drop pulleys again within the next couple weeks, I am anxious to find out how much power it's putting down. Almost anyone who changes over seems to love it. shoot me a PM and I can help you with your specific tune. Should be able to set up a tune for you that will work well.
