Understandable but BMS told me that 2-3 gallons of E is fine to use with the JB+. The HPFP and injectors on the b58 gen2 is actually capable of up to e50, but since JB+ is just a piggyback, stock tune fuel trim map can't compensate past e30ish.
Yeah the whole E thing is a bit odd considering this to be the most mildest tune and cheapest lol.Am I the only one that wants to run the car on pure 93 and leave it at that. Why is everyone obsessed with adding Ethanol on almost stock cars. Surely it's not worth the trouble unless you are bothering with a half decent tune?
This.

The reasoning is simple. JB+ is adding nearly 5 psi of boost and has no logging capability. If the engine is making timing corrections (ie pre-detonation), I would have no way of knowing. I am taking the precaution and using E to raise my octane to ensure engine safety and improve performance consistency.
Not really. The information in this thread is confusing and there has been no clear link made between running any mixture of Ethanol vs pure 93ULP causing a net benefit. In this thread, all Ethanol has done is add an unnecessary layer of complexity on what is arguably a simple no nonsense mod. I'm sure I'm not alone in saying that if I have to blend Ethanol to use the JB+ it's a complete waste of my time and not worth the price of admission. Besides, isn't 93ULP beyond what the stock Supra tune needs anyway.. and therefore already acting as a so called precaution?
Suit yourself. Taking 3 extra minutes to fill a couple gallons of E at the pump is neither an inconvenience or extra cost for me to do. FYI - Owners manual says E25 is perfectly OK (page 326). Perhaps give it a try before discrediting the 4 of us (And BMS) who have tried it. No one ever said it was a requirement for JB+, just said that it helps with power consistency.Not really.

While I understand the benefits of running Ethanol blends in tuned vehicles, in the case of the JB+ I think it is largely just placebo.
And? Just because it's OK doesn't mean it is good. Besides, without logs you said it yourself:
You realise this applies with or without Ethanol in the mix right?
Not really willing to continue discussion if you aren't being constructive. If you try the JB+ with and without E and still hold the same opinion, leave that feedback here.
You still don't have your car... and the manufacturer of the product literally said it was okay.
Ok mate.
That's fine. I was trying to show you that your reasoning is flawed but whatever.. enjoy your Ethanol use and the benefits it brings you.
Does this apply to an automatic, too?Suit yourself. Taking 3 extra minutes to fill a couple gallons of E at the pump is neither an inconvenience or extra cost for me to do.

Yes.
