15psi On 10psi Generic Capa Flash

[quadie]

Not sure where to post this and tried searching but couldn't find a good answer

So finally I get my Flash tuner2. Being greedy I head straight for the 10Psi map.

Fash goes well car starts. Setup data logger on laptop. warm car up watching the

logger so the vital signs. all is good. head out down the road and give it a hit.

And as soon as the boost raises over the std 5psi(boost guage) it breaks out into

wheelspin. hit 2nd (auto) all is good. continue on sedatly having a quick look at the laptop

all data seems good , AFR's EGT's all withing safe limits. boost settles at 10Psi

I haed of smiling down the road. head for the highway to do some more logging

nice clear road , give it a good hit, check data all is well. knock it into 3rd and floor it from low revs

boost rises to 10psi .. then continues out to 15psi , back off, check data, data shows 15psi spike

try 2nd , and boost heads to 12 Psi. head home saftly to check forum for any known issues

most overboosting is noted with exhust changes . mines is completely stock only 3 mods are

K&N panel filter , bov vented to atmo. plugs down to .89.

Any1 have any ideas as to why such a big overboost on stock setup with just an edit?

Thanks

sorry if its been answered but I couldnt find it anywhere searching

Two words - generic tune.

The generics aren't tailored to your car - hence the name. Your boost control could need fine tuning, or your actuator could be too soft. Best bet is to get a custom tune ASAP - what do your afr's look like on the data logger?

Hey bud, I had the exact same problem as you and after a lot of reasearch I decided to do the actuator and waste gate mod (I would highly reccomend XR6Turbo Developments they did a top job) I have done this mod and am still running a generic tune, I have done the data logging the same as you aswell.

I know everyone knocks generic tunes, but my car is making good/reliable power, with just an exhaust, cooler and generic tune 10psi (awaiting $$$ for custom).

but yeah do some research, I ended up finding 2 people in my area that wanted to do the same mod, saved $$$ on postage and what not.

Hope I could be of some assistance

Another question, senna_T have you done much with the data logging program or know of anyone that has?

I am just wanting to find out what increments the readings are in?

GET A CUSTOM TUNE!!!

I would not trust the generic tunes as I have had first hand experiences of motors blowing up on the 10PSI generic tune...

At least you have technical knowledge and realised right away it was over boosting...but other people who just load up the generic tunes and just keep drivng around their car with it overboosting and pinging end up desintegrating their motor....

HI

I just purchased the flash2 unit for my F6, and have requested a 10PSI tune that I expect to work as good as a factory tune.

Considering my car is standard with no modifications, the capa generic tune should be perfect.

I would be very pissed of if the tune is not 100%. Why?

Because a custom tune should only be needed if you change major components like injectors.

Does Ford have bolkes at the end of the production line doing custom tunes for every car? No.

If the 10 PSI tune has problems, then I am certain that either Capa have not done a good job, or its all in the game to make you spend more money!

Anyway, I hope all goes well with it.

Cheers

LMAO...best of luck

Yeah in a perfect world that would be the way, but...

Ford writes the mapping for these cars very conservative, in regards to timing and fuel metering, ie rich on boost, and tame timing to prevent knock on hot days/lower octane fuel ect.

A 10psi generic tune basically has the timing advanced to help make more power, more boost as you expect, and more fuel... but, there's a limit to how much fuel the stock injectors will flow.

On standard boost, they have plenty of reserve fuel, on 10psi they are close to maxed, so your motor is now ever so close to detonatation.

Throw in a hot day, petrol that you thought was 98, but really wasnt ( it happens ) and it pings.

This limited safety margin is why poeple are allways saying, get a custom tune, get bigger injectors... sure ford puts the same programs in all the same model xr6ts & F6s, but they have big saftey margins built in.... generic tunes don't.

Not bagging you or dictating to you, but its just the way things are with these cars and our tuning platform that we all love to use.

Cheers

Hi Chris,

I understand your point but it doesn't make sense when all I am asking for is a proven and reliable tune to upgrade the power of my standard car.

Capa must have tuned many cars to know what is a safe reliable tune with a small margin for saftey.

The worst thing was what the tuner said to me after he offered a custom tune for $500 bucks. I asked the question "Do you update the comupter live or do you update the Capa box and then download it into the car - If so, It would take a long time to get it right ?" His response was that he updates the capa box but he has so many files from past cars that he may only go thrugh this proceedure 2 or 3 times. This is fair enough, but for $500 bucks I would expect he would be on the dyno almost all day fine tuning - the price doesn't justify the work if this is the case.

Anyway, I haven't even loaded the file into my car, so I am probably jumping the gun and being too negative before trying it.

I fully agree on a custom tune after any modifications to the cars factory Hardware.

Cheers

Ahhh, the lure of cheap and easy horsepower...

And everyone know that most experienced tuners will "cut and paste" tunes. That is, start from a base tune that has very similar mods to yours, then go from there. Its saves time amongst other things.

I agree with you if the tuners have had so many cars why the $500 fee?

I understand that they have got many tunes for variouse mods and you would think there would be a bit of a price drop becouse of all these saved tunes and it takes less time now days.

$500 is a bit rich
