Switching between E85 and pump on chrome?

[TUFFTR]

Apologies if this has been asked before. Running a chromed ECU with the SL ROM, currently having it tuned for 98RON (Australia)
My question is this.
I have an AEM progressive meth injection kit which I am in the middle of installing. I like this because it runs off the MAF signal, not a primitive on/off

I haven't seen (please show me the way if I've missed it) if there is say, switchable maps, between, let's say a pump fuel map, and an E85 Map.
Is this possible with Chrome?
If not, will it be?
Is it possible, but you need to flash on different maps? (bit of a pain to have a laptop and flashing cable with you everywhere, but do-able I guess.

I'm now second guessing myself a bit. I spent a shitload of money on the Meth kit, not wanting E85, but I've just seen the gains on an NA 3.8L here in Australia (15% power increase just from E85!) and it really got me thinking. I just don't want it to be a fiddly way of switching maps.

Anyway, I guess that's the jist of it...

Gotta use the laptop for now to reflash. Greg is supposed to have switchable maps all tested out waiting for release with the next Chrome update but he's working on some other stuff before he's sending out the update.

Greg plans to use the active exhaust switch (AE) to implement this. I believe it will use separate sections in memory to load tables for fuel, boost, timing, etc and you will just switch between them with the AE switch.

there are already high and low octane maps for timing and fuel, it would be amazing if the ecu averaged between them via a e85 sensor rather than knock level.

[TUFFTR]

Well. Really good to know this!!
Because that would be perfect......I mean....a friggin waste of me buying the brand new meth kit really!
Does anyone have a timeframe on this? Might be worth me picking up some high impedance high flow rate injectors and a stainless steel fuel filter to get tuned on this later on......
Car's currently being tuned via email for the next few saturday's (lost licence, need friends to drive it for me!) so if it this came out in 2-3 months time it would be perfect

Switchable maps has been done a long time almost a few years but he didn't want to rush it with the v2 release so it will be on the next with more features. I believe the majority of the flex fuel coding is written but not tested at all or at least he said the equations he needed to use for blending fuel and timing based on ethanol content was going to be easy. He has a flex fuel sensor but has been busy trying to figure out a bigger MAF solution.

Awesome news to hear!
The main reason why I opted for Meth > E85 is the range, i.e. On meth + 98 I can drive 1000kms no issues with fuel. On E85 not very optimal, as there are only servo's local to me.
This is very good news...
Guess I'll be on the hunt for some 450's in the meantime

Most maps have a high/low octane but not all. Like the start up tables for example. Those I had to rewrite from scratch.

I can do amazing things with the code.


...just seems like no one has a running car these days.

running absolutely fine here

So this means you're ready for me?
