    im no forum mechanic, but im pretty sure a salesman wants to keep his customer happy. and under delivering with a less than stellar tune is not easily overcome.
    so by your method of though, the tune is actually delivering less than what the #'s shown?

    got links to said DD discussion?

    I think I'm going to promote this issue to the front page later today if that is ok with you.

    Would you mind pm'ing me with what you paid and some further details? Thanks.
    Actually, I'd prefer to wait if there's a chance I messed up the test by not letting the car adapt. I don't want to look (more) silly if it was partly my error...

    I'll go back in the next week or two and if the results aren't 20-25hp higher, I'll be raising my complaints with the dealer and Dinan.

    I paid $2400 for the flash.

    That is smart, I suggest you do a dynojet this time around if you can find one though unless you want to stick with them since they have your baseline.

    ok, ive read the input about dd and straps. i hear what your saying now. i just dont see it as something the dyno operator would have knowingly done in this scenario

    Thanks. Problem is I don't have a baseline there, so say I go and put down 440whp - won't know if that's better or the same as the 400 on DSGs dyno dynamics.

    Well, true, but if you put down much higher numbers we at least have a reference of a stock N63 on a dynojet putting down mid 380's. So, it would give you somewhat of a clue.

    Dsg has no interest in n63 tuning. However each time its removed the results are not quite the same. People need to be aware of that.

    Sorry, don't really understand this post?

    DSG?

    Each time what is removed?

    OTS?

    Sorry Bren, just asking for clarification.

    Sorry if it wasn't clear - flash was done somewhere else, only dynos were done at DSG.

    Thanks for posting the graphs.

    I actually just got my Dinan tune today on my 2011 550i x-drive.

    Comparing my "day one" driving to the graph, I'd say it's pretty close.

    The extra 100lb rwtq is very noticible and close to the advertised 125lb increase at the crank. As the graph shows, the rwhp numbers are up 70+ between 3000-5000rpm. It is disapointing that the gain drops above 5000 rpm and in the end only picks up 40hp , but overall it's still pretty impressive for real world driving.

    No regrets on my part.

    DSG = the dyno facility he used

    Each time the car is removed from the dyno, the strapping changes and that could possibly change the result in which sal@evolve emphasized recently with data.

    i never heard of this strap issue before and next time im at the shop im gonig to experiment to see how much power it can produce, with that being said if we are really going to add "strap pressure" to a variable on a dyno number then we might as well stop talking about dynos!!
    your car only made x cuz of y
    your car only made y cuz of z
    your car only made z cux of d
    your car only made h cuz of g

    should i continue??

    Great point. It does feel great driving, I guess my issue is that's not how Dinan sells the tune. They advertise 495hp and 573lb-ft, not 70hp over stock through most of the rev range with 40hp gains at peak.

    Even though I like the added power, I'm left feeling a bit short-changed at the moment.

    apparantly it only refers to that type of dyno though. it makes sens when sal/evolve explains it.. sorta, in theory..

    Do you happen to have any dynos of your car?

    You say there were 6 hours in between the dynos. So, the stock dyno was early in the morning and the post flash dyno at the time of the highest ambient temps, correct? If these are uncorrected figures it would easily explain why the gains seem to be less than the real gains.

    Good thought, but I don't think temps had a material impact. The baseline was done around 10:30am, the after around 4:30pm. No more than a 5-6 deg F difference outside and the dyno was done inside with the doors closed using a large ventilation fan.

    I'm not going to sweat it too much until I get some dynojet results. Spent most of the day yesterday doing a proper interior detail Click here to enlarge

    Some pix of the car from my PCD.

    Bren M3 - you and me going to be good friends!

    Guys, this dyno comparison is useless. It's needs scrapping like the rest of the dyno nonsense put on most of the forums.

    Who cares about strapping at this stage!

    The fact is that not one graph has a correction factor and therefore we have no idea of what's going on.

    I don't think anyone actually realises how much error can be made from one dyno run to the next and the only thing that can prove this is posting the correction factors for 'each test'.

    I really would like to make a video about all of this but I simply do not have the time to do it. Someone fly over with a camera and I'll explain everything in detail!

    Now, looking at the graph a little more carefully something is evident. Power seems to drop off lower than stock at the higher rpm's. I can GUARANTEE you that this is not actually happening in real life. That car may well have been strapped differently.

    Adaption is an incredibly important process for these cars to go through also. 3 runs? That's not even close to enough!

    Also, what we don't know is what the running temperatures were before and after.

    If operators actually start using these machines properly they can log:

    Ignition Timing
    AFR
    Long Term Fuel Trims
    Short Term Fuel Trims
    Inlet Temperature
    Coolant Temperature
    Etc etc etc....

    All of this information can be recorded for each run and shown on the x/y axis.

    So we have no idea about strapping, correction factors or running temperatures.

    So this kind of testing is so incredibly unscientfic and non conclusive that no one should even attempt to say anything about the Dinan tune.

    My personal opinion on the tune looking at the graph is that it's actually pretty good and is designed such that the car will actually make power consistently and not over heat the engine.

    ^ Keep in mind, it isn't his fault. He deferred to the operator. Considering the numbers are not what he expected or wanted I don't think the operator was playing games.

    Secondly, he is getting a dynojet run soon which should tell us more.
