Dampend vac/pres feed

[b'have]

I currently use the dampend feed from the plenum for my map sensor and use a seperate undampened feed for my fpr/ebc.
Should all those feeds be dampened? Anyone know for sure?

Yh thats fine Charlie. Their main function is to stop any moisture getting to the electrical sensors like the MAP.

Cheers Ryan, getting near to finishing it now, looking good for some mapping in March?

:thumbs:

I have the morning on the 15th free and then in the afternoon im mapping at SRR so we could stick it on the dyno after we have done some of our famous road mapping :rlol:

Sounds good to me :) Pencil me in please.

It stops the MAP sensor getting a reading that is, in technical parlance, "all over the shop" as well. I did a thread on here somewhere demonstrating the difference in signals. Swapping back to the dampened output for both stock and GReddy MAP sensors certainly fixed some wibblyness in my fuel map :)

And that :D

So, should I share the dampened signal with my ebc and fpr? I would prefer dedicated feeds for each (I have 5 feeds from my new plenum).

Boost controller and BOV can be undampened as far as I'm concerned, a boost controller is a kinda coarse device that fluctuates constantly anyway, don't be fooled by it's display showing a rock solid figure :)

The FPR? Probably I'd run it off a dampened connection, having said that I can't recall what mine is off at the moment so it's probably sat in the garage undermining me by being attached to a non-dampened output as we speak :)

I would just run the Map sensor on an Dampered line as this is the most sensitive. I doubt you would notice any difference if you logged the Fuel pressure with and without.

I bet you it is :D

Also Mr C get your name down for the SRR day again. We can have a chin wag and a fiddle with that IGN table of yours :p

[Ian C]

The timing is bad for that alas, I'm away in Italy :complain: for my brother's wedding slap bang in the middle of those two dates, although the later one (24th) is more plausible.

Might even have fitted the WI by then lol

Just had a mail from your fpr moaning about your ign map. :)

[Ian C]

Actually it needs some dyno tweaking for one ignition aspect for sure, as the stock ECU retards ign by 10deg once you reach the stock rev limit. I want to find the balance point where I can wind in +10 deg to counteract this to say 7200ish, without putting in say an interpolated +5deg at 6700rpm and detting it's nuts off :)

Doing that on the road by myself at 150mph doesn't appeal...

PS tell my FPR it can go suck vacuum :p
