Hello all.

Curious if anyone has had a similar problem to this.

Got ussual mods and a 10-12PSI tune with just over 270Rwkw

Im getting what can only be desribed as mini repetitious fuel surge...?

Later on in the RPMs on full boost in first and second its like a small engine/car shudder of it extremely quickly loosing and gaining power.

The car has never done this before even under 1/4 of a tank and its now doing it with half a tank of fuel.. Ive replaced the fuel filter without any improvement.

Scan tool shows no codes relating to this fault. Ive got a suspicion of it being the FPR. May even be something else?

Anyway, If anyone else has experienced this your input would be greatly appreciated.

Thanks, Dave

Try logging a few things with your xcal during a wot run. Should give you a better idea of what it could be.

Oh thanks mate, completely slipped my mind.

Never used the xcal for data logging before, I've used different editing tools before. I'm guessing it's as simple as following the prompts?

Very easy mate. Download livelink from the herrod website and off you go. Just need the USB cable, same one most printers use.

Okay I've done a bit of logging.

Can somebody please reccomend the most vital 22 things to log and if possible there names..

So many settings and only a 3rd of them seem to display information.

Ive had a look at basic things and they are all within completely normal specs..

Except for inlet temps.. OMFG! Furk the monza, even right down south in the cold bits.

Are you logging on a xcal3 in a ba? If so you can only log the lower case pids! Need a xcal 2 to log the rest,

What temps do you get?

Yeah xcal 3 in a BA..

Damn.. Im like one of the only people with a tuned falcon in my town.. Doubt a xcal2 would be available.

I saw it go upwards of 150, Not sure if its displayed in C or F? either way that's pretty warm.

No one can recommend settings?

Im actually leaning towards valve springs. 1st gear WOT doesnt seem to have problems, Change in to second WOT and it has the shudder.

But no lumpy idle...

I just bought a xcal 2 for datalogging cause a newer device don't work lol

I had the same problem as u! Flat stick as soon as it hit 5500rpm in first there was a surge! Not fuel as I have a surge tank. Replaced plugs and coils and now all is good. 1000klms later problem is back :/ sometimes........ Logs are mph and F

When my springs were shagged car would nearly stall after giving it a boot full but no problems with surging....had to give it a rev and then it returned to normal

SCT is always in degrees F.

You need an xcal2 to log the DMR's which hold all the vital info like the source of torque reduction requests etc.

Is it a problem that just just started out of nowhere? I have like 3 spare regs but I have never seen one fail so I would be very surprised if its that.

Yeah it just appeared out of nowhere.

I did my plugs and coils less than 10000kms ago.. Genuine coils too, It gets pretty wet down here but I extremely doubt water has got up there and damaged them.

Its fairly random too, Sometimes it does it sometimes not, Much more apperant in the cold though.
