I think this is a bit of an overreaction. Think about it, it is ONLY on the component above $57k and the increase is only 8%. Let's say you pay $63k incl dealer delivery for an F6, you are currently paying ~$1500 LCT. With this 8% increase you will be paying ~$1980 LCT, so a $480 difference. That is hardly going to dissuade anyone with that sort of coin. Who pays full price for these vehicles anyway?

No, he isn't. LCT is only on the amount above $57,000. The first $57,000 has no LCT applied. The difference from the 8% increase would be less than $200 at that price.

Where do you buy this stuff? Is there anywhere online or a major chain?

Now I'm really embarassed. On our sh*tty, slippery track up here with a 10psi generic tune the best 60ft I could cut with the ZF auto has been 2.4x so far. I am basically putting it into performance mode and flooring it. What other techniques are quicker? Is launching in 2nd quicker?

Just wondering, someone with tuning knowledge may be able to answer this. Say you have a factory standard car, on the factory tune. You fit 50% larger injectors and now need to modify the ECU to rescale the injector size. Is the injector size a simple value in the ECU, or does the tuning software you use (e.g. CAPA, the sniper one etc.) take the new scalefactor and multiply all fueling values by this scalefactor? Also, if it is just a simple value, once youve changed that, will the car run approximately the same AFRs or does it need further fine tuning?

Is this the "$2000" I've heard previously mentioned? That's not too bad if its for real... but it contradicts what a local mechanic here said "... we looked down the CAPA route but the software is ludicrously expensive so we'll wait for the HP Tuner software ..." Does the CAPA solution also require anything further than a Flash tuner purchased like perhaps a serial to USB interface or similar?

So what is the deal here, we still can't tune our own cars? I know in general it is best to leave tuning up to tuners but it is frustrating we still don't have something for personal use like the LS1 owners (are they using vcmsuite?). There is a subsection of enthusiasts that are clever enough (and conservative enough) to learn to tune their own cars on the road with a wideband O2 meter and a laptop and tuning software. So CAPA Advantage is for workshops only, Sniper seems to be crippled for home use (is this right? only allowing crude high level changes?) and noone seems to have bought it, and HP Tuner for the XR6 turbo still seems to be vapourware. If the HP Tuner software does eventuate is it likely there will be a personal tuner edition like the LS1 stuff? I.e. full functionality for tuning an individual car but missing stuff like the ability to tune multiple cars, locking etc? I have no tuner available here and would like the ability to make minor adjustments to my tune, make use of injector scaling etc, and maybe even tackle a full tune when I feel I am ready.

No torque curve unfortunately sorry. Still interested in seeing some more stock dyno sheets to see what boost control is like if anyone has one.

[quote name='Adam' post='670065' date='May 4 2008, 10:41 AM']I disagree... If the pump has a higher pressure then you'll find that the car will run richer.[/quote] richer I can deal with as long as its not like going from standard injectors to 60lb injectors :)

I'll take one for sure then, thanks. Cheap insurance.

Do you need a retune if all you change is the fuel pump without changing injectors? I am a bit worried my fuel pump is dodgy and would be interested if it doesn't affect the tune.

what exactly is wrong with those AFRs? I'm talking about the boost "curve" on the standard tune not the AFRs

Yeah that was great fun.. I'll be back for the next one (colder night) My slips say the track temp was 45 degrees! 13.8 @ 105mph was my best I think. I really have a long way to go on my 60fts couldn't get below 2.4, the track was utterly ridiculous.. I could hear all the T's spinning into 3rd. Results are here http://www.hiddenvalleydrags.com/raceresul...lts20080502.pdf Interesting on my run with the slick tyred Clubsport I still ran higher mph and he ran 12.9.

Dyno chart attached. Boost control on the stock tune looks woeful to me.. is this normal? Note the 3 tunes are standard, 8psi and 10psi .. lowest to highest power respectively.

It's not actually overboosting on any of the tunes. The 8psi and 10psi tunes do as they're supposed to. The factory tune boost goes up and down all over the place but no higher than 6psi, which I believe is normal. I'm just not sure it should go up and down all over the place though and not hold boost steady.

We can't get a date without getting numbers first unfortunately and securing a tuner. Let's just say we'll run for early-mid August.

A custom tune isn't going to fix a boost control problem (I.e. if there is a problem with the wastegate for example). Either way, I can't get a custom tune here in Darwin.

Hi All Just wondering if anyone had dyno charts from their standard car so I can see how much boost it was running and what the boost curve looks like. I just had my car dyno'd again on the factory tune and 2 other tunes (C&V) and on the factory tune something is very wrong. Boost goes up to about 6psi and then drops down to 3psi and then back up to 6psi again late in the rev range. The boost control solenoid has been lubed (right before the run and other times) so it doesn't appear to be that. Ridiculously it put down 230rwkw on the factory tune, peaking late in the rev range right where boost hits 6psi again. The other two tunes look better, peaking at 8psi and 10psi respectively before tailing off ... should boost on the factory tune really be so all over the place? The car is pinging (very mildly) on all three tunes but AFRs are fine. I have a feeling there is a boost control problem somewhere. Will post the charts later. Adam

+1 on this. No joke how bad this can get. 3 of mine were finger tight and another support bolt on the turbo to block support was half way out. Car only has 17,000kms on it and was supposedly serviced by Fraud a few weeks earlier. My book says 105,000kms for plugs but this is a BF2

I have been having a problem with my car for some time now which I thought was pinging (sounds exactly like it). Had other people listen to it, and the Ford service centre listen also and they also agreed it was pinging at the top end. This was on the factory tune. This had been going on for months and 3 visits to Ford and still the same old sh*t, can't find the problem, bad luck etc. I changed plugs, fuel filter and did a million other things to try and diagnose this. Someone on this forum suggested that there is an outside chance it may be a loose bolt and not pinging, but may sound identical. So I took it to a local mechanic friend and we put the car on the hoist and the first thing we noticed looking up at the turbo from underneath is a bolt that is more than half way out (!) that supports the turbo against the engine block. We also removed the factory heat shielding and looked for exhaust manifold bolts that may be loose and what do you know, 3 of those are loose too (finger tight). This is a known problem with these cars and Ford even have it in their manual (for my BF2 at least) that the exhaust manifold bolts need to be retensioned at EVERY SERVICE. The car had only been serviced a few weeks earlier so the bastards obviously didn't do it. I haven't heard a peep from the car yet and it sounds like the problem may be fixed once and for all - it may not have been pinging at all. A few more days hard driving should confirm this I am so pissed that Ford can't even follow their own maintenance items and have decided this is the last time I will take the car to a Ford service centre.. what a joke. In 3 visits to them surely with their knowledge they should have been able to spot a bolt that was well on its way to falling out!

I'm struggling to understand why a tuner doesn't just jump into this thread and end the speculation. I'm inclined to believe what C&V say as opposed to what you hear from Ford employees

I've got a few XR6T's parked at work so I will leave a note for them .... from what I can tell we probably only need about 6 or so to make it happen ...

I'll start - 10/2006 Ford Falcon BF2 XR6T - ZF 6 speed - Currently have an F6 CAI, flash tuner but will also have a ProcessWest stage 2 intercooler kit, MetalCat, Siemens Deka 60lb injectors fitted by the time the tuner arrives. - Car is currently running generic tunes - Looking for a safe and reliable 300rwkw with perhaps 12 or 13 pounds of boost and another less aggressive tune

Hi All I am hoping to get a tuner up here at some stage in the near future to tune a few cars, but to get the ball rolling we need some numbers and information for the prospective tuner. It would probably be best if we also get strong commitments from people to go ahead, including a non-refundable deposit. Accordingly, if you are interested in having your car dyno-tuned by a reputable tuner, brought up to Darwin from wherever they may reside, can you please post the following details: - Make/model/year of car (e.g. 2006 Ford Falcon BF2 XR6T) - Transmission (e.g. ZF 6 speed auto) - Mods you will definitely have on the car by the time the tuner arrives - Whether the car has been tuned already for the mods that are on it or not - What you expect from the tuner (e.g. do you want a high boost and a low boost tune? how much boost do you want to run? what's most important to you.. reliability, drivability, big power etc?) - Contact details (via PM) You will need a CAPA flash tuner and importantly, if you are tuning a car that is modified (or to be modified), the mods must support each other. e.g. there is no point fitting a plenum, exhaust and intercooler to your BA when you haven't fitted tougher valve springs and expect the tuner to be able to tune your car. Pricing is yet to be determined (depends on interest, and negotiation with the tuner), but expect it to be expensive. Many tuners charge nearly $1000 for a tune but spend a lot of time on it. It is likely the tunes will cost more than this given that the tuner needs to travel here, requires accommodation etc. However, this is a small price to pay given the alternative of getting your car to another tuner interstate, having the tune done and getting it back here. We will need to find a dyno we can book out for a few days. I can't imagine this being a problem, but it would be great to hear suggestions on which one we should use. Finally, I am not sure at this stage which tuner we can entice up here, but be assured it will only be a top shelf tuner that contributes to this forum regularly and has a great reputation for their work. Thanks guys. Adam

So you reckon a T with 55kw at the flywheel wouldn't be capable of moving at all?
