Oh, and the XEDE conditionals were programmed, in this case, to work with the factory narrow band o2 sensor. No wideband in this car! AFR display on the right....

I have had that thing blow off 3 times

. Luckily, race gas and the stock ECU have come through for me. Just another point that its damn near impossible to blow up a car w/ a XEDE

That (using the narrow band o2 sensor ) is excellent shiv. Can this feature be used with the "nonsmart" maps?

But of course. You can also have the XEDE trigger conditionals based on knock activity as well. But getting that input will require the optional knock buffer for $100.

I will install somewhat of a poormans version of this, but by using totally different mechanism. It's called alcohol inj with a flow sensing unit that supplies 5vdc to a WG act solenoid when less than 200ml/mil is sensed.

Pulling the hose off the regulator at 20 psi would not cause engine failure in any other kind of situation. I don't agree at all with that statement. I have had the FPR hose blow off an many cars at different levels of boost. I have yet to hurt one from it.

I have a question:
I was about 21 psi at around 7000rpm (not sure may be more) in 2nd (wot) and for some reason, the car felt like it gradually lost fuel. It wasnt sudden but wasn't like the limiter either, kinda in between.

What happened?

My fp has been running in hi mode in mid throttle recently, could it be going bad or is it something else? no SES either

THANKS

There are atleast 2 other ports on the intake to tap into. The BOV line is the easiest.

Not trying to cause any problems, but men should stand behind what they say. Would Dave be willing to pull the line off his car in the middle of a pull? On pump gas? Genuinely curious based upon Dave's statement (and the fact he knows a lot more than I do). I am trying to know what I see as a discrepancy between what he said in this thread and the linked one.
