    RENNtech N54 Tune Update

    Compared to the previous RENNtech tune or Alpha, the current update is just another animal. How do I though explain this in words ? Well it can be explained in words because when you love something you tend to over exaggerate its contents. Numbers is the only conceivable and understood communication that plainly tells the reality of the store.

    I havent been focusing on launch control much from since after I got my drive train and diff replaced. So I decided to focus more on "shift points" in the RPM band.

    My second time out on the PBIR track with the new RENNtech N54 update I was starting to discover the "sweet spot" in shifting with the updated tune.

    Unfortunately last night was crowded with all the muscle bound guerilla oil pissing cars, that continously dropped oil causing delay after delay.

    I was only able to run three times, within 4 hours, experimenting with a combo of shift points.

    With less effort on a 60' I was able to establish a 12.0 ET with a 2.0 60' @ 114 mph with a significant increase in the 1/8 @ 93 mph

    Does this signify a high 11 second car ? I will leave that for you to decide.

    Will need more time on the track to experiment more. Good thing there is a PBIR private event hosted by Street Car Drags coming Sunday Dec 9th 2012 to put in as many runs as I can

    Much thaks to the RENNtech team

    I think it's more your transmission than the tune. 114mph is nothing to brag about from a tune. But the results are very good.

    Very Possible, I am nearing 200 launches from since I bought the car new. The December 9th event will surely put me over 200 launches...

    Holding on as much as I can to see how far clutches will go. Need to do a 4th pull on a dyno to see if I am loosing power somewhere or if I just need to shift differently.

    My Name is ET 12.0

    Seriously, these were my runs yesterday back to back. There was dew on the other half of the track. I passed through two patches of it that almost caused me to lose control. If I didnt have my DSC on I would have been kissing the walls. Thats why my ET MPH look so awkward. The first run, 1 hour before the other time slips, there was no dew on the track at all.

    I agree with not running DR's but you should dyno the two and see the difference.

    Surprised you are able to run that with traction control on. I always have to fully disable it.

    it was bad. I ended up in the middle of the track twice lol. I didn't finish a single run without coasting thru. you will run 11s easy BuraQ. the track was scary last night.

    114mph isn't the best trap for the mods. I would be gunning for 117mph and considering you had a 50/50 mix of 100/93 octane you should definitely be targeting more than the 111-115mph range.

    There's no harm in trying out a different tune.

    I think he has nominated himself to be official forum RENNtech spokesperson. More power to him. Click here to enlarge

    But we've had customers run 11s @ 115mph+ on pump gas and stock tires 3-4 years ago. Not really a big deal. The way we do the tuning, the features, etc, have changed a lot though. A static flash like the RENNtech is simply obsolete these days. You are better off using a Cobb tune or JB4 to achieve the same or better results with more features and convenience.

    Obviously you offer more features but I just want to comment that that the power delivery of the Renntech flash likely offers a consistency and smoothness it is difficult for the piggybacks to match.

    I'm an all out performance kind of guy but there is something to be said for flashes as well.

    No offense to the Renntech guys and OP, I'm sure they are great, and do nice things on other platforms, but this N54 tune is just obsolete flash technology. There is nothing better about it except that OP seems to be getting special attention on getting his car dialed in. Good support is always nice.

    But I'm just calling it as I see it here. Click here to enlarge To put it another way if he were to run a JB4 piggy tuned by myself, or Cobb AP flash tuned by Dzenno, or even a PROcede from Voldemort, I'm sure he would have better results, more features, better drivability, in a package he could install and remove from the convenience of his driveway, for less money.

    I have ridden in his car and I will say without a doubt that the drivability of the car is very very smooth and consistent (as shown by his timeslips as well). Kudos to Renntech for the job well done on his car that makes a vast improvement in power compared to his previous tune.

    Its always nice to have more options in the tuning world and I am sure with his relationship with Renntech, he will be taken cared of whenever an issue should arise.

    Frist of all, your not acquainted with the PBIR track. Just because someone can do average 117 1/4 speed trap on one track doesnt mean that can achieve the same speed trap on another track.

    Secondly, for my mods being that I am not running cattless speaks for itself and expecially with stock midpipes.

    It has already been laid down for the reason of my low speed traps that night. There was dew on the other have off the track in whcih I went through two patches of and had to slow down

    I have been known not to jump on the same band wagon with everyone else. After Dinan I just got more hungry power and desired to go another direction.

    I am not a DIY person when it comes to a problem with any of my cars. When there is a problem I dont want have to call up Cobb or any other tuner to find out wtf is going with my car and then be told send us logs. I like it when I have a problem to just drop it right off and be done with it and not have to wory abotu the mathematical game.

    I have always considered Cobb, but I just found a tuner that provides warranty, and support that NO OTHER TUNER can match.

    No offense to the Renntech guys and OP, I'm sure they are great, and do nice things on other platforms, but this N54 tune is just obsolete flash technology. There is nothing better about it except that OP seems to be getting special attention on getting his car dialed in. Good support is always nice.

    But I'm just calling it as I see it here. http://www.bimmerboost.com/images/sm...icon/smile.gif To put it another way if he were to run a JB4 piggy tuned by myself, or Cobb AP flash tuned by Dzenno, or even a PROcede from Voldemort, I'm sure he would have better results, more features, better drivability, in a package he could install and remove from the convenience of his driveway, for less money.
    Different strokes for different folks. I like what Renntech is doing with the BMW platforms personally and their Mercedes turbo tuning is pretty much the best out there right now.
