Aps Remap's

[danko]

Hi there

I have had my car remapped by APS, but doing so when I had it done there wasn't a running road (Dyno) so I didn't receive any before and after information. but I had the car dyno'd today and it's showing 365BHP! and in the books its 420PS (which is 414.25 in BHP) so on a new car realistically it should pump out about 390-400BHP at the least, but 365... we checked the fuel and its running before 10 from 16~ and it should be around the 13 mark consistently, but its running ridiculously rich after the map.

I am not sure on what they have changed, but it looks like they program one software and then just apply it to all cars, rather then do each car as an individually item.

If others have had it done please post your feed back, as I am annoyed before it's showing 365BHP after the map, so I don't know if it was there map that done something to my car. They did mention due to it was a 09 car on the ECU there was a blockage, but after a day they somehow got around it, I was a little bit skeptical about it, but they saying that the car has more torque and faster through gears so I physiologically think to me self its true because its "Mapped"

After having it on the Dyno and seeing the results I am not very happy with the remap service.

I will also contact APS in regards having there "map" taken off and a full refund.

Sorry I do not mean to come across as a slater, but the results I got, I am just shocked! and also seeing the car running so rich its not good!

Oh and on top of that I have the Miltek system installed (Which is loverly) and it adds a solid 20BHP and the remap adding 10~15? so that means my car comes out the factory as 330BHP that's not right at all. So if you can see my point the remap is the only mod that has altered around the car's settings, so Im thinking its the remap that has caused this.

Give me your thoughts

Sounds like the map is a bodge up or hasn't been applied properly.

Personally I don't believe half of the claims for re-maps and after market exhausts.

There is nothing for nothing and what you gain in one area you must loose in another.

If it was easy to get more power with no negative side effects the Audi would do it in the first place.

From the nitemares I have heard @ remmapping I am afraid to let Audi fiddle with my '08 R8. And a dyno is definitely in my plans to have as proof to show incase of a bad remapp so I can reverse and refund if bad things happen. Hang in there.Your situation is very relevant..The speed throttle is a nice new gadget from LLtek.com/r8speedthrottle.Has anyone tried one of these?(on ANY car) ?

quick question is the 365bhp on the wheels.....or is it crank, cause our cars should get around 340whp to 345whp ( on the wheels ) which equates to around 420bhp......now if ur getting 365whp then the remap did do its job and ur actually getting 25whp more!!!! usualy tunes are made to run rich so dont sweat it too much.

Thats what I'm thinking also. Here is a Dyno showing power at wheels with EVOMS Software and stock

Thanks for the reply guys, I believe it's at the crank, as the guys was shocked when they saw the results seeing Audi claiming (420) and the dyno showing 365.. I told them how the APS guys "mapped it" they took data of the car loaded into there computer and then tweaked the binary codes which was in chunks of different maps of the car. then they just fed the "new" data back into the car. Even now I am still skeptical about it, as I was there I saw a van outside saying " something tuning" and I asked the guy who did my car, and he said its his company, and he just did the remaps for APS and sell the service under their name. So anyways I asked the guys who Dyno'ed my car on how they would do it, and they said they will have the car on the dyno to get a reading, then access the entire code of the car and look at different sector to see where they can achieve better power from, and doing this each map links to another as if you do one change you tend to have to change another for them to all operate together properly. With APS to me, is they just get the R8's original data "tweak" it and apply it to any R8, with mine being an 09 model, it has the Audi ECU block on it to stock tuners changing the data, however they managed to get around it after a day.

I am just going to ask them to load my old map back and get my refund as this is most likely the reason for my car to be showing 365bhp and also the richness is way below the number it should be steady on even after a remap which is around 13 and now its on boarder 10.

With the company that dyno'ed my car, at least they can proof to me the area's they looked at and tweaked and show a graph of improvement unlike APS providing no proof, part from myself psychologically thinking its faster as I know it just got mapped?

Il will contact APS with regards this, and I'm sure they will see this post as they are active on this site. I will ask them to re-install my original map back in and get refunded in full. What do you guys think? Would you do the same if you was in my situation?

Looking at the Evom's results, there stock power is around 380~ and mines at 365 with Miltek and the APS "Map" Definitely something isn't correct here.

Yea I'm not getting that chart. Here is one showing an R8 with supercharger against a stock that has a Stasis exhaust. I have a Stasis so like seeing the gains they claim verified by someone other than them

Also I would like to dyno my car, I heard Audi's can be a pain in the ass to strap down, Did you have any problems having yours done?

I would have a couple of questions:

1)How could you be measuring "crank" BHP unless you have your engine out in a test bed (and then it's "flywheel" really); if they didn't pull your engine and they're talking "crank", they're extrapolating (read guessing). I don't care what claims they make for their software, unless they've got a database off the same car (R8) I think "correction to crank" is B.S. because there are too many variables and they're different from design to design.

2)Was your dyno a proper awd dyno with measuring brake on both front and rear? Not enough to just have rollers up front; minimum 5%+ of power is going forward under all conditions

3)what do 4.2 awd R8s normally dyno on the awd dyno? 20%+ flywheel to rubber driveline losses are pretty normal with awd cars (and sigt. higher than 2wd set ups)

365 sounds very good to me on an awd dyno and probably better than stock, though I don't have any figures; I have some experience with awd Volvo R's (2.5 liters rated 300 hp stock but normally awd dyno around 230-235) and Subaru WRXs also I know can have 20%+ "loss" from flywheel hp on the awd dyno.

Both these cars, BTW, are fairly highly boosted turbo cars that can benefit DRAMATICALLY from remapping and wastegate tweaking as well as intercooler enhancement). An atmostspheric engine like the R8 4.2 is not as likely to be leaving much on the table for the tuner to gain. The factory boosted cars are always a trade-off between getting the high brochure number and keeping the thing from blowing its guts all over the street at a stoplight while it's still on warranty!

That's not the case with an engine running at atmospheric pressure. Virtually all tuning enhancements just improve air or fuel supply or valve timing or revving ability and don't adversely impact longevity, so the oem has much less incentive to hold back. Not that the after market tuner won't tell you different.

Bottom line is, the 365 sounds to me like you DID benefit from the remap. Moral: Don't Tune Your Car Until You've Dyno'd It Stock!! (Even someone else's car's numbers aren't necessarily an entirely valid benchmark.)
