FVD ECU FLASH results
 
Just finished loading the "tuned" file that I received from FVD to my ecu.

There is no noticeable difference in the throttle or the car's performance.

The only thing I noticed was that they did get the rev limiter raised to 7400 versus the 7200 factory setting.

So far $500, wasted.

I will put the car on the dyno this week. possibly twice. I am thinking about flashing ecu back to the original file while at the dyno. If I can get 4 pulls.

Adam 02-26-2010 01:46 PM

Well that sucks :( People spoke highly of that tune to. Maybe the dyno will tell a different story than your backside?

that's why I said so far. Maybe its me.

After installing the FVD software in my vehicle, I could discern a marked improvement in throttle response. That is to say, that the throttle response felt noticeably more linear and consistent throughout the "powerband". Unfortunately, some enthusiasts expect that re-mapping the ecu suddenly makes their vehicle feel like 100 hp has just been added. That is simply not the case. Like many performance upgrades, the actual increase in performance can sometimes be subtle or incremental. I would recommend driving your vehicle some more, particularly under various driving conditions, and see how it performs.

Dyno It!!
 
Has anyone ever noticed how better your car drives and feels when its clean!! Just our perception!!

Put it on the Dyno!! That will tell the truth!!

Well, some members can rely on their "butt" dyno to give them a good indication of power. I for one, have incredibly sensitive "cheeks" that, believe it or not, can readily detect power increases in one horsepower increments. :)

Steve Tinker 02-26-2010 11:43 PM

It's a good job you included the :) to your last post JD, otherwise people would get the wrong "impression" of your cheek sensitivity..... :rolleyes:

landrovered 02-27-2010 03:44 AM

Be sure and watch The adventures of Johnny Danger, bionic butt cheek boy in "where did my horsepower go"!

Johnny Danger 02-27-2010 05:04 AM

I've been building "cheek" strength for awhile now using my Jane Fonda workout tape. My goal is to some day be able to crack walnuts. Right now I am able to tackle peanuts, the styrofoam ones. :D

nope, it is actually a much smoother ride, really.

update 3-3-10
 
Scheduled dyno for this Friday 0900. The car has been running great. I think it will put down more than 246 rwhp this time.

and on a positive note i've been driving the car for 3 days now and the usual rear 02 CEL's are gone.

they disappeared when I flashed the tuned file and have yet to return.

Sounds like a dramatic improvement in one's outlook has occurred. Let us know what the dyno results show. :)

it's really hard for me to tell. I've had some fast straight line cars (1800lb curb weight on 15 lbs of boost). sometimes the boxster feels really slow and other times not to bad. like from a 5 mph roll in 1st. I think its just me. will see tommorow.

2K3_Boxster_S 03-05-2010 12:43 PM

update post dyno
 
All I can say right now is Bad news. my initial feelings about the car were correct.

FVD is currently working with me to correct the situation. I will not post the results unless they refuse to 1. resolve the situation or 2. refund money.

hopefully, I will have new dyno results next week sometime.

MikenOH 03-05-2010 05:04 PM

So--how bad is it?
do you have dyno reading before the flash?

Yes, I do have dyno sheets and video. before and after flash.

And yes its bad negative gains in HP and Torque. all I can say now. waiting for them to get back to me.

will have stock tune file dyno results tommorow night.

What did they say exactly? Try the stock tune again? Did they offer to modify the profile on their tune?

jhandy 03-09-2010 06:34 PM

Disappointing to say the least.
Thanks for saving me some money. I was going to buy that flash.

yes, Re-flashed with the stock tune file and re-gained HP and TQ. tuned file was dyno'd 3/5 and stock file dyno'd 3/10. same dyno, same gas used, etc.

Just wanted to be %100 percent sure because I was going off last summer's stock file dyno. The dyno' time is starting to equal the cost of the damn software.

I am sending the results to them tonight. dyno sheets and Videos. I don't know what there plan is. I hope they will continue to work with me as they have been very good so far. I don't want to throw them under the bus yet. They may have an answer. We will see.

I received a new file from FVD to try when I get back to VA. right now I am working in Vancouver, WA and will be working in Bremerton, WA next week.

So, mid april I will try this one last time and get it on the dyno. stay tuned for the fun :cheers:

Hope it works out this time. Are they willing to refund you the money if their software doesn't lead to the increased hp gains they claim?

They said they would. they don't even want me to return the cable. It can't be used for any other cars anyways. it's chipped once it's used it registers the VIN number. They have been very good so far. hopefully the new file will show improvement.

Any update on Whether FVD has been able to proived software that yields a gain?

Re-flashed with an updated file sent from FVD. The car was Un-Drivable. Lurching horribly. I have responed to FVD with this information. Now there replies are starting to come slower and slower. Last time it took a week for them to reply. I am done playing games with this company. Hopefully they do the right thing. lets see.

Boxtaboy 04-27-2010 02:33 AM

If they don't do the right thing, post about your experience on 6speedonline. They are a board sponsor there and have a big following. Sorry bout your experience.

MN 986 04-27-2010 07:24 AM

I am sorry to hear about your experience, I was also considering this re-flash but I will now cross it off the list. I hope they follow through on their promise to stand behind their product.
I had a good experience with FVD with their 'sound version' muffler. Boxtaboy told me about their muffler having a little more sound vs. his Dansk (which I was also considering) and I am very happy with the look and sound. I read a lot of posts on 6speedonline, and they do have a strong following over there. I worked with Rhonda, and she was very helpful. I mentioned that I had read a post where someone had concerns with their flash, and it seemed like she had not heard about it but was concerned. If you aren't working with her, it may be worth contacting her. She is the person who posts on 6speedonline for them.
Good luck!

There are many of us who have had very positive experiences with FVD products; especially their ECU software programs. Moreover, in my experience, FVD's attention to customer service has always been exemplary. You clearly have something going on with your vehicle that escapes anyone's understanding. I have a nasty suspicion its those NHP headers.

Re-think, what you just said. As soon as the car is re-flashed back to stock file the car runs fine. Those nasty NHP headers help make an overall bolt on HP gain of 18 HP. That comment makes no sense whatsoever.

I know a few people who have had issues with those headers and cats. Namely, ongoing problems with CELS, and in some instances a loss of back pressure as compared to the oem set-up. Nevertheless, was FVD made aware of the fact that you are using those headers and cats ? And, were they sure to have written the software to accommodate these changes in equipment. Especially given the fact that you are now using 200 cell cats.

landrovered 04-27-2010 06:43 PM

The only part of the post combustion cycle of the engine that enters into the ECU EFI functions are the o2 sensors. The ECU does not care how quickly the exhaust gasses leave the cylinder, only the completeness of the combustion and the effectiveness of the cat. The MAF would reflect and correct for the greater flow through of the engine and the pulse width of the injectors would be set according to the fuel curves.

In short, headers not being taken into account would not cause the sort of problems the OP is describing.

You have provided an excellent answer to the question. However, if the MAF is not properly correcting air flow and fuel mixture due to a change in headers and cats, even if this is occurring on a low detection level, is it possible that re-mapping the ECU to increase these mixtures can exacerbate the problem ?

landrovered 04-28-2010 09:44 AM

Sure an improper curve can have an effect on the efficiency of the engine but...

The pulse width is the only real tool that determines the richness/weakness of the combustion mixture.

Now, headers could have the kind of effect you are suggesting if the pulse width was already at the edge of the rich or lean curve area and the headers had the effect of pushing the setting over the edge in either direction.

But I cannot imagine that the pulse width would not be set closer to the center of the band to ensure a good mixture and it would likely be set to the rich end to avoid predetonation and micro overheating associated with a too lean a mixture.

It may be the case but I do not think the headers can the cause of the entire problem.

blinkwatt 04-28-2010 10:29 AM

From what I understand and what I have spoken to w/ Rhoda about FVD,they don't even make their own flash....

FVD has their own affiliate in Germany who does their ECU programming for them.

Yes, obviously they were informed of my entire set-up. If you were at all familar with how FVD works you should know they wouldn't even send you a file without this information. You have to have an active internet connection to flash your ECU which validates your VIN and also sends your stock ecu file to them at which time you specify your mods and what redline RPM you prefer as well as whether or not you want a Top speed limiter removed etc.

2K3_Boxster_S 04-28-2010 07:03 PM

Also,

on a side note. on the first tuned file that resulted in negative HP and TQ gains the AFR's improved over the stock readings to idealy perfect.

2K3_Boxster_S 05-10-2010 06:11 PM

Final Post. FVD A+ Customer care
 
FVD is willing to continue working with different files for my car. I have chosen to give it up. It is just not working with something in my setup. MANY people have had positive results with this flash and I do not want to discourage anyone from trying this software. The re-mapped E throttle response and raised rev-limiter worked fine.

FVD issued me a full refund at my request.

FVD's Customer care is A+ and one of the best I have dealt with. I will continue to do business with this company, as I have 2 orders placed with them right now.
