I do not mod my car, personally. Haven't made it to a shop yet. Doing research.
Thanks a lot for your helpful response. Much appreciated.Hey man, welcome to the forum. I see that you’ve posted 133 times in about 14 days. Love to see the enthusiasm. My recommendation to you is to check out the search feature here. Much of what you’ve asked and have started new threads on has been covered in detail.
Here’s a picture of it for reference.
To answer your question with a very short answer:
1. Not safely. It’s very likely you will cause a lean condition without some system adjusting for your E content, and definitely would be guessing about what blend you’re mixing.
No, you cannot run pure E85, even with a proper tune it’s erroneous, because after about E50/60 you start to actually lose power.
2. 2022 Supras CAN be tuned, there is a ton of information about it. It’s not cheap, and you will be without your car for awhile while your ECU gets unlocked and potentially cloned.
2a. If you don’t want to spring for a tune and all that’s involved with unlocking your 2022, but are set on making more power, look to the piggyback systems on the market. The most popular is the JB4 unit by BurgerMotorsports. The jury is out on overall longevity and reliability running a piggyback that essentially fools the ECU into thinking it needs more air / fuel / boost etc, as opposed to a full fledged tune which will directly interact with the maps on the ECU. Even with a JB4 unit, you’ll need a FuelIT sensor to measure, sense, and take advantage of any E content you’re putting in the car.
Hope this helps — and again, welcome!
And yes, I know about sending the ECU to Finland for $3000 but I taint doing that.
Yes and no.
Maybe if you’re driving a 30+ year old car. Modern cars are fine with ethanol from a corrosion perspective. The problem with E85 isn’t corrosion, it’s fueling requirements. Ethanol requires about 40% more fuel per gram of air to ignite/burn properly. E85 simply requires so much extra fuel that the stock fuel system can’t keep up, you end up having to drop the boost so low to keep from maxing out the fuel system that you make less power than with a blend. If you add a stage 1 pump and port injection to handle the extra flow then E85 is fine.
Happy be educated here though.
It can. The stock map will support up to E25 as-per the owner's manual.Would adding 1-2 gallons of E85 to a tank of 93 even do anything on a stock tune? I have always assumed it was pointless to add any E85 if you are bone stock because the stock tuning won't adjust for it.
It could be used for knock prevention due to the increased octane and cooling, but I'm not sure if that's even a concern in the first place on the stock tune.Would adding 1-2 gallons of E85 to a tank of 93 even do anything on a stock tune?
