This is true...

Ran e85 on 2jz is300 that was boosted and it was great! Ran it with 1jz injectors, wide band flex fuel and stand alone ecu... do not recommend this with a 5vz unless you build it to support more than 6 psi...calling @gamefreakgc

anyone tried this?:
APE Flex Fuel

I've never seen that before but looks pretty slick. Surprisingly, installation doesn't look too bad either except for how to figure out the fuel line connection.

Definitely has potential but you would have to be the guinea pig and try it first. We do not have the ability to advance timing so there's not as much of a power gain compared to other vehicles.

Interesting. It doesn't do anything with the ignition timing, E85 needs a bit more advance for best results, but that would probably complicate things quite a bit. Just bumps the injector open times up a bit based on the ethanol percentage.

It's pretty easy to plumb the ethanol sensor into the return line since that's not pressurized. Easier to keep non-pressurized fuel where it's supposed to be.

This is the way. 315cc injectors, either blue ones from 2JZ or lime green ones from 7MGE will work. They flow ~30% more fuel over the stock 245cc brown injectors.

I am currently running the 7MGE injectors, and ran a few tanks of E85. Long Term Fuel Trims (LTFTs) were in the low single digits. What's interesting is I can still run regular gas without tripping a CEL. The LTFTs go negative into the high teens, low twenties but apparently not enough to trigger the CEL. I have the California emissions that has the Toyota AFR sensor (i.e. wideband O2) and I can see what the AFRs are doing. The ECU has no problem holding stoich with either fuel at part throttle conditions. I have not observed WOT open loop AFRs because I rarely ever go WOT.

My brother ran a I think Dobek module on his ZX12 Ninja that basically did the same thing. Intercepted the injector pulse width and tweaked it. It worked great until someone figured a hack to the processor of his ZX12’s ECU.

It states that the factory ECU will run more timing advance with the APE.

I had the ability to advance or retard timing and adjust fuel curves with my Perfect Power SMT5 piggy-back, which died this month... Bought it in 2003. I'm pretty sure the MAF output circuit is toast. I can talk to it with the software, check all parameters, see the AFR in the software, so I know it's SEEING the MAF input. I can also reset it to factory, configure it for my engine, etc, but the engine will not start with it in line. I put the bypass plug into the connector. It's a black box sealed in epoxy, so no fixing it either.

They also had a 6 and a 7 with more features, They are now out of business.

Oh well, it was fun while it lasted.

Not very true with the 5vz, but many/most other models that is reasonably true...

Would you elaborate, please? TY

The 5vz ECU completely ignores the knock sensor below ~3k rpm and runs fixed (conservative) timing in that area. This is why the supercharged guys lave low RPM pinging issues. No idea *why* but, there you go.

The 5VZ-FE is mechanically noisy which is why I think they designed the knock sensors that way. I thought you might have some secret knowledge I wasn't aware of. 😉

Obviously there are a lot of solutions to the HGLRPM ping issue now.

Thanks for the response.
Cheers.

Hey, I appreciate the responses. I realize this not simple, BUT...E85 is *almost* half of the price of 89 octane here in CA...and if it may be at least remotely possible to convert...it would be worth the effort.

I went one heat range colder with my sparkplugs because of this. Between decking the block and heads for my rebuild I probably have .25 to .5 more compression.

The closest E85 to me is a 30 minute drive and is the ONLY station listed in the Portland, OR area. There are 5 total stations listed in Oregon on this site: Alternative Fuels Data Center: Ethanol Fueling Station Locations

Looking at the map, besides California, it's mostly east of the Rockies... WTF?

It’s very possible and simple. Throw in a set of lime green 7MGE or blue 2JZ 315cc fuel injectors, and go fill up with E85. I would recommend replacing your fuel pump with one from URD that’s E85 compatible.
