More issues with the beast K&N intakes made my problems even worse

avry8542 · 15th September 2007, 06:51

I went to get my car dynoed today because of all the issues I am having with the new OEM flash from BMW. Still not better we are way below my best number of 484rwh. They had a pair of K&N typhoon filters in stock. We got a 25 rwh loss after install. We knew the car needed to be driven for a good 50 miles for the ECU to adapt but the car was on the dyno already so we just made some passes for the hell of it. Please tell me that this is because the car was not driven. My car is sick and I have to get it better. This v27 flash from BMW ruined my car. Driving home today it felt like it was in p400 when I had the setting maxed out for full performance.

ALSO I NOTICED TODAY THAT MY CAR IS GETTING 6 MILES TO THE GALLON AND i WENT THOUGH A QUART OF OIL ON ONE WEEK. Doe's ANY ONE HAVE A IDEA WHAT THATS ALL ABOUT/.

[FONT='Times New Roman','serif']Are you referring to just the K&N filters, or the entire intake kit? If filters, there has been a lot of discussion that appears pretty conclusive the filters are a power suck. The intakes on the other hand...I don't think you can blame the intakes on the problems you're dealing with right now. The whole software issue is amazing, the oil draw is terrible, and something is definitely going on with your engine. Like has been said, getting air/fuel information is probably critical right now from your dyno runs. The intakes could hurt your engine performance given the headers if they pushed the a/f mixture too far out of wack, and v27 probably worked against some of the same changes your headers orginally created. The verdict on the latest software (v26.x or v27) seems to be to stay WAY away from it.[/font]

I got the intake kit. Doesn't it take time for the ECU to adapt to the filter

Not really. The ECU is running millions...or billions...of calculations every second. It does adapt to your driving style, but as far as environmental parameters (intake flow, engine operation, exhaust flow, gas quality), those kind of changes and calculations for optimal performance are nearly instantaneous. If anything, a few miles of driving to warm up the engine and at least have the sensors operating cleanly with the new intakes/exhaust/etc. may be necessary, but not days of driving. I guess I'm in disagreement with others on this, but I've talked with K&N's engineers and one of the guys at Dinan and they both noted that the ECUs in today's cars are incredibly more powerful...reading sensors hundreds or thousands of times a second and not operating on any memory of these readings since the engine can adjust almost anything, at any time, instantly.

This is your car speaking. "I am perfect and stop putting these mods on me that make barely any difference." I may go for an exhaust and wheels but that is about it. You guys(sorry not trying to make a blanket statement) are putting way too much money into these cars and I know the investment you are all making is not worth the return. The worst things about it is giving the dealer the chance to give you crap about warranty work. They are already enough of a pain in the arse to deal with. I understand that your concern is the new 27 software, but I doubt they would bring our power down without there being some sort of riot breaking out.

GreatM5Dane, thank you for your wonderful insights. Now please repost this in 50% of the threads on the board so we can all learn from your great wisdom.

I was not trying to hurt your feelings sorry.

James.

We did a before and after dyno. Right after the intakes were in we started the car. No warning lights. We made three passes. 25-30 rwhp less with the new intakes. Is it possible we did not give the car adequate time to adapt. We installed the intakes while the car was still on the dyno so we didn't even drive the car around the block. I totally agree with you that they should adapt pretty quickly, but maybe the fact that we started the car and dynoed right away is not enough time. I drove the car around last night and put about 50 miles on it. No warning lights. This morning I started the car and I got a engine loss of power message. It went of in as soon as the car warmed up. I have been turning the car on and off intermediately. I read to do this from guys on the board. James I have had nothing but problems and loss of power that is recorded on the dyno form the new OEM flash that BMW put in my car. I here that v27 will cause a conflict with modifications. I am very pissed because I told BMW when they did they change my oil and did the work on my clutch that I did not want the ECU flashed. They did it anyway. I am actively using my connections to find a way to downgrade the car back to its stock Version 24 OEM version. I was told that It can't be done by the dealer. They said only a BMWNAtech with a special unit can down grade the software and the car components. The dealer said that if they just install the v24 software the components that are upgraded in the car will conflict with the older ECU version. It makes sense. I would think its like downgrading windows xp to windows 95. If you dont downgrade your divers to the computer will probably not work right.

If you have any knowledge on this I would really like your advise. Since this new OEM update I had the ECU sent to AA for the stage to re flash. We did get a gain in hp but the car ran weird. The smg was hesitant and the car just felt lower. I heard form several people that BMW put encryption in this new software to make it almost impossible for tuner to enhance the ecu. I know for a fact that before this update my car was a beast. The AA tune was aw some. Not only in power put in drivability and shifts, it was awsome. I know is nothing AA is responsible for. They flashed my v27 ECU with the same parameters as the old one. But is it possible that BMW really did something to not allow the tuners to Work on these cars. Russ Ramz had a thread on this. Maybe AA did give me more Horsepower but maybe there is something in the OEM software that is playing games with the re flash. This all sounds crazy but this is what I am going threw.

Please if you have any advice or you know any BMW tech guys can you find out what is going on.

Do you know if it is possible to downgrade the DME-ECU to version 24 once its been updated to v27

PS. I WANT ALL THE MEMBERS ON THE BOARD TO KNOW THAT IN NO WAY IS THIS A ISSUE BECAUSE OF ANY THING ICS DID OR THE ACTIVE AUTOWRKES TUNE. BMW IS TO BLAME. THE NEW OEM SOFTWARE IS GOVERNING THE CAR. THIS IS WHAT I WAS TOLD BY ALOT OF PEOPLE. DOES ANYONE HAVE ANY KNOWLEDGE OF THIS. IS THERE TRUTH TO WHAT I HAVE BEEN TOLD.

Thanks

Avery

do you think the dealer will give you the whole void warranty song and dance because you have header and AA StageII?

Man Avery I feel your pain !!! That is incredible not being able to get your car back to where it was. I can't offer any helpful input but I will sure ask people I that know these cars. Last Sunday I sent several hours talking with Mike of Active Autowerke. Also the guy from ASR Engineering is local and he really impressed me, really sharp guy. Have you discussed this with Active? What do your guys say? Got to get the beast back. Juan
