It's only going to turn on if boost goes high enough to enable it.

If you don't want it to turn on at all, even in boost, map B should be blank all the way across the board.

You could also put a switch on the negative wire that's hooked to the chassis, then you can manually turn off the negative. No negative, no power.

I ask because I'm not sure how my LPFP will take this right now and if it doesn't like it, I want to disable it until I get my Stage 3. Also would running this with a 50/50 E85/93 mix hurt anything?

Map A will be the only map that'll have any changes made to it. Map B is left blank, at least so far. Basically leave the SS in map A if you want it active and adding fuel. The two maps on the first page don't effect Map B. One of for the N20 Map sensor and the other is for Stock map sensor.

I may end up doing this.

Maybe I don't see the info somewhere, but how do you switch maps on the AIC? Over the serial cable?

Edit: It looks like the AIC only uses map B for a different firing pattern with more injectors/strokes so you can't switch to that map, unless I'm understanding something wrong. If this ends up being a problem I might just look at the serial protocol for the AIC and add a fuel map editor to the apps.

The AIC we provide completely ignores map B.

Hi Terry,

Are there any updates to the PI maps? It would be helpful if you could put a date next to it or version number of some sort.

As for the backend flash, do you suggest lowering the Fuel Scalar and altering the AFRs? Saw that you said you use slightly leaner AFRs, but how much is "slightly"?

That is an original AIC4. IF you have that model the boost reference connects to the diverter valves. Also you must copy fuel map A to fuel map B.

I have a 100% E85 MHD back end flash file. It might be what I already sent you? I'll be adding the 100% E85 flash files to the first post shortly.

No the AIC4 only reads up to 26.5psi give or take. But this is suitable for up to 30psi actual boost. I ran it for awhile with great results. Just be aware the maps are a bit different than what is posted. If that was the used one I sold then it already has maps loaded. Leave those on there to start.

ps. Checked the email and it was you. I'll forward your invoice back over to you to refresh your memory.

No codes. All running fine.

I have the same setup, I occasionally get the jerk but can usually avoid it by letting off the throttle gently. That said, it probably shouldn't jerk like that even when letting off abruptly.

Got a log of the "jerk"? Wonder if it's going rich for a split second...no pun intended.

I think I have several logs of my car doing it Steve. Nothing looks out of the ordinary though. It's weird.

Wait you threw me off here, so with the split second bic we can only boost up to 30 psi? What about those single turbo guys pushing over 30psi?

Its almost certainly running very rich, the injectors included are intended for large turbos, on stockers you need to run much smaller injectors (like half the size) to achieve proper results. When you run the ipw so low (10-20%) its not utilizing the injector properly, your car will run pig rich as it can't pull any more fuel than it is already.
I'd suggest looking into these for stock turbos:

Let me go through and find a good log that may show something. If we're talking about the same thing it's like a random buck once you drop off the throttle.

Its impossible to know. When you let off the gas the throttle closes cutting off oxygen to the engine. So even if extra fuel is injected during that time, it won't result in any power generation. A log of it coming up might shed more light on whether there is a mapping issue there that needs to be corrected, etc.
