    VF Version 4 tune E46 M3

    I have to say that the version 4 tune has made me fall in love with my car all over again. When I initially got in it, I was pleased to start the car and it idled quiet and steady. After clearing my adaptations I eased into boost to allow it to adjust accordingly. I did notice for whatever reason the car seem to pull harder earlier than before. It has a nice smooth transition powerwise between shifts. The car is nothing short of amazing now. I have to say that it satisfying power for the street and then some. Hats off to Nik, Paul, and the VF crew for working this out. As a shop owner myself, I understand that tunes must be revisited and updated...dealerships have to do this as well. This is why I chose to be patient and wait for VF to work it out. And they have done just that. Now on to answering the general questions:

    1. did you have a tune with your vf stage 2 before this?Yes, I had the GIAC ver 3 tune

    2. if so, what was it (e.g. the previous mafless tune, last maf+ tune, etc.)? mafless

    3. if yes to #1, then did you ever get ses light on for "cat codes" with previous tune(s)? No SES light for me.

    4. if so, how often did it appear (e.g. every few hundred miles, etc.)? NA

    5. what headers and cats are you running? if you are catless, be sure to say so. AP Headers, AP section 2 with j-shaped o2 bongs, no cats

    6. when is the last time you got a dme/ecu update from bmw through the gt1 (approximate time is fine- e.g. early 2007)?2007

    7. how many miles have you driven since getting ver4 software? 100ish today

    8. any issues with the car since getting the software including but not excluded to ses light, hesitation when taking off from dead stop or slow roll, rpm hanging when shifting at wot or close to wot, idle roaming on cold start, idle roaming on warm start? NNone at all. The idle is perfect no matter what, hot or cold start. 11.1-11.3 at WOT.

    9. if you have had ses light come on with ver4 software, what were the codes/causes?

    10. is your car smg or 6mt? SMG

    11. do you have the new or old intake manifold (if you are not sure, "new" has "vf" in raised lettering on the front of the manifold; "old" is the one in the pics seen below)? New Intake Manifold

    12. what is your afr range at idle? 14ish.

    13. what is your afr range at wot? 11.1-11.3

    14. what is your peak boost? 8.5-9

    15. what is the ambient temperature range (approximate) at which you are providing answers to #12, #13, and #14? 30-37

    16. what is your location? Fayetteville, NC

    17. if you know, what is the altitude at your location?

    18. does your vf stage 2 car have mods that are in addition to or modifications of the standard OTS stage 2 kit (e.g. water methanol injection, smaller s/c pulley, different trim s/c, etc.)? No....well not yet anywayClick here to enlarge

    You can read my feedback from a post sticky made. I have been very pleased with the results from the new in houe tune.

    They did the right thing and got away from the GIAC tune. They did it in house so I wouldn't think the investment would be huge as to bringing in someone from the outside, just time consuming.

    It's ok, he's an owner and sharing his experience. We don't have much VF info and I am interested in his feedback.

    Elaborate on that large investment though.

    An additional question I would have for you would be what issues you had with the GIAC tune? Idle search I presume? Anything else?

    Yes, I had the idle surge on cold starts with the previous GIAC mafless tune. At times, I had the throttle stick. All of these issues have been resolved for me.

    Thanks for your reply. No, I don't spam on every forum. I was under the assumption that forums are to share information, so that others may research it...I'm not sure of any large investment, I just know they invested in correcting a tuning issue that they trusted another company with. Usually when you can't get someone to do something like you want it to be done, you have to do it yourself.

    They are, no worries, happy to have you share your experience and I'm hoping to get more details on this new tuner at VF. I think I'm going to try to interview him and Nik Click here to enlarge

    I think that would be a great idea. They can talk through what they had to change in the GIAC tune to get the tune as good as it is now. I am really enjoying my car again. The car is more alive then ever now.

    What I want to know is why GIAC couldn't do it.
