Don't get me started on DIY, and support/documentation. I'll leave it at that.

 

Hehe... I'm going to do this and document it then! Since the one and only E85 station in BC just opened 5mins from me and the owner is a previous customer!

 

Good. Do it.

It took me a whole thread to get 2 simple questions answered. Nothing pisses me off more than vague documentation that literally just mentions like 1 setting of like 10 and you just have to magically know everything else.

 

I envy your ability to get e85. My closest station is 50 miles from my door.
Looking forward to you figuring out how to configure the flex fuel sensor... it might come in handy for track days or something on my NA.

Lower combustion temps for the win!

 

Its DIY man, Do-It-Yourself, not Do-It-For-Me

Just giving you grief.

bcrx7 the main issue that I've seen is noisy signal from the ethanol sensor. Read here for more info: https://www.miataturbo.net/general-m...ecklist-84106/

 

$600 bux is the difference between the two
lol
It's all good, I know you are.


*Edit: parked the car until the DW gets here, hopefully tomorrow.

 

Right. It looks like one or two people tried it and nobody is reporting if the filter fixed the issue...

 

According to msextra, that filter issue only pertains to MS2. I started a thread and one of the main developers said that hooking it directly to the MS3 should work.

 

I switched to a return style setup, I like it it's very consistent/repeatable in boost vs the stock return-style setup. AFRs are literally a line now vs a wavey curve of whatever they want to be. First time I saw it I though my wideband was locked up not updating....

 

Also I keep EGO on with 15% authority. I recommend it as it should help you deal with variations in gas/ethanol mixtures.

 

I use EGO correction as well, but only after my Fuel table is perfect and doesn't require much compensation.

I achieve perfection before I turn on a band aid

 

Pat: Maybe the returnless explains my wavey AFR's. Perhaps the dampers are bandaids themselves. 15% EGO is huge, especially up top.

18: I think that just the changes between Winter and Summer gas, we need to:
1) Adjust Req_Fuel seasonally,
2) Use EGO
3) Run richer in the summer by default.
4) Use long term trim. I don't know if anyone has tried this. I'm a little scared to try it. I'm also trying to get to the point that I take the laptop out of the car.

I think #2 is the worst because it will always chase a little. But I do use it with diminishing authority as MAP goes up.


With changing levels of alcohol, how can you get VE table dialed in without a sensor?

 

What you need is an octane sensor. I have one sitting here that I can send you, but the shipping is pretty expensive. It will solve all your problems.

I don't want to take a picture of it, because I don't want anyone stealing the design. It works by allowing the different octanes to separate, then you connect the fuel pump to pull from the "level" you want.

Ok, so maybe it's a processing tower from one of the refineries here. A little big and heavy, but it's amazing what happens when you show up with a bunch of flatbeds and just start doing something. People think you belong and don't ask questions.

 

A lot of OEM's actually go up to about 15%, but of course all of them run OL in boost.
1) I've not had to do this before. It wasn't as big a swing as some think, at least not here in CA.
2) This is always a good practice, but ONLY after the map is completely dialed in and consistent/perfect. Never to compensate for unfinished map.
3) I tend to run my cars on the rich side anyway, and even more so on pump gas (91 junk here). For instance: some run 12.0-12.5:1 in boost even on pump gas, and I wont do that even on e85. I don't take chances.
4) I use it all the time on other cars. Not on a miata.......yet

I don't know about your guys' states, but here it doesn't swing that bad. I've never seen long term trims swing more than 5% on a properly tuned car.

When I say the alcohol changes, I mean when I was going from pump gas to e85, for the 1st tank. Now that I'm on E, I don't expect it to change that much.

at least I hope. at least it hasn't before. who knows.

Also on E it's so forgiving, you can run 13.5:1 in boost and the car won't even hiccup.

 

Let's see who gets it

 

DW200 came in. Went in right away.

Then I went out and completely re-tuned the car. It didn't completely throw off the tune, but there seemed to be enough places that the fueling was different that I just felt better starting from scratch.

3 hours later and she runs like a champ.

The real test will be over the next few days with varying temps and conditions, but I think it's good now.

 

All day and for the short drive I just did in the evening she ran like a champ.
In fact, a little on the rich side, which is fine.

I know I keep saying this, but IT'S SO MUCH FUNNNNNNN

Today I trolled a modded 05 WRX Wagon. Little home-boyz in flat brimmed hats and it was insane loud, so probably "stage2" or something. The best part was when they finally pull up to the next light and his passenger is like "damnnnnnnnnnnn, what's done to that thing, it flies!!!"

I smile and say "intake and exhaust"

PS: the look on their face as I'm passing and flat-foot-shift right in front of their window, shooting a nice flame - PRICELESS

Who woulda thunk a miata could be this much fun?

 

Intake and exhaust...

I lol'ed... Props for that.

 

This thing was on 2nd page... Can't have that!
