Bf Injectors With Good Spray Pattern For 300-350Rwkw

Sounds funny but you want a full custom tune

So many places do NOT do that hahahaha

Boost is intake temp selective and a bunch of other multipliers all of which work together to give a "dynamic" outcome, ford smashed it with the stock calibration its amazing

Some tuners wont ever bother to keep this up when lifting boost/timing/afr so effectively dumb the system down

Times money and your another dollar .....

I'm aware that this takes time and money, I did it on my old skyline and ended up having to do it myself as other tuners wouldn't put the time required into it.

Intake temp vs enrichment is pretty easy to do on other ECUs, a very simple 2D table of degrees vs % enrichment (entire map is enriched apart from idle), only takes about 2 minutes to set up properly.

Ignition temp retard was a similar 2D map on the ECUs I've used. Do the ford ECUs do it this way? I'm guessing they provide more variables and are hence more complicated to do.

Afr will change with intake temp and coolant temp, fuel temp can also be a factor, peak engine torque is closer to around 4700 rpm on most of these motors

How is it set up though, a simple 2D map?

I know what your looking for and its not like that bud, AFR's are scaled in the "normal" temp zones and TP so when temp increases its usually the IAT's throwing things around or the physical state of the fuel at the time

this is why a tuner needs to account for EVERYTHING as best as poss when tuning these cars, this is why its maintaining a steady state of lambda but just equal leaner, allowances and multipliers need to be set up right

Yes, stock pcv check valve is ineffective at those sort or pressure, it allows boost pressure into the crankcase and this forces oil mist out the crankcase vent.

A can on both is best, otherwise a check valve to prevent boost pressure entering the crankcase and a can on the pcv is a must imho

KPM said they have never seen a PCV fail and think it is just increased blow by, so you have seen it fail yourself?

[Ralph Wiggum]

I've never seen on work. Take it off and blow through it

[rollex]

Got the car retuned, it is like night and day. Made a way more midrange and low down power, and even more top end. Car drives so much better, no more doughyness or needing 75% throttle to make boost, also doesn't backfire all the time like it used to. I've never had a tune change the way a car drives this much, It literally feels like a different engine. Can't hear it pinging any more either.

I'll post the dyno curve up later, I realise you can make them look better/worse but end of the day how it drives is what matters and how it drives reflects the new dyno sheet, eg way more midrange and down low.

PCV is apparently working fine as well, they couldn't get it to pass but I might check it myself later.

As long as your happy mate

Here is the new dyno chart

Here is the dyno with the old one overlayed, this is with their "flywheel kw" number, no idea if it is accurate or not. Either way you can see the extra midrange which is what I was raving about before.
