E92 335i and 350Z vs C32 AMG

[kindafast]

I was at a car meet in Mexico tonight, met my friend with a E92 335 stage 2 ecu and asked him for a rematch. We ran before when he had the chip and I was stock. Right now I have all the mods listed in my sig, he only has an ECU. About two weeks ago I ran a different e92 335i (stock) and beat the guy confidently in all the runs we did (3+). Well this time it was a different story. We did our first roll at 60, he got a jump on me and kept pulling, after a few seconds I knew it was over for me, we kept going till he braked up to about 130~140, by that time he had a good 3 car length on me. A moded 350Z was riding along to watch and he asked me to run him, we did a 20 and a 60 roll and I beat him both times. The Z had aftermarket cats, FMIC, some other stuff I can't recall, he runs mid 13's. Now back to the bimmer; we pull up to a red light, the guy didn't wana do a dig cuz he had problems hooking it up but I convinced him and with massive wheel sping managed to get a jump on him, by the time I was doing 50 he started to slowly pull on me, by about 100 he passes me and begins to slowly walk. Well.. I gotta say I tried and there is no way in hell I can beat that car with my current set up. I gota be honest I'm amazed what a single ECU does to the performance figures of that bimmer, stock C32 is supposed to be neck and neck with stock e92 335. Once I get the pulley though...

im assuming the 335i had a piggyback as opposed to the Dinan ECU? Do you know which one it had? Proced V2 or V3? JuiceBox? SSTT? or the Helix Attache?

It is impressive what those cars can do with just a piggyback. Many immediately drop to mid to high 12s trapping 110+ easy on pump gas

turbo > supercharger for power.

Why did the 350z have front mounted intercooler if he's na? i'm assuming he's NA if he's running 13's.

I have seen videos of 335i with ECU & exhaust keeping up with E60 M5s

The 335 is one of those cars that REALLY PISSES OFF E60 M5/E63 M6 people, such as myself lol(jealousy factor)...with a simple ecu, that car can be as fast as either of our cars...I have a very heavily modded m6, and came across a "very stock looking" 335i about 2 months ago...i was able to get ZERO separation on him until the very end of 3rd gear heading into 4th. Just wish it was as easy to mod my car as it is to mod that one lol

That's why I'll eventually get rid of the M-pig and go FI baby! Tired of this NA

He didn't have a FMIC, my bad, I dunno a lot about those cars. he had some cooling mod that I forgot.

I love beamers but..... Those 335 seem to blow turbos pritty easily. They can only handle around 14/15lbs of boost. If I had one, personaly I'd go with Dinian just because of the warranty.

You said you ran him before when you were stock and he was chipped like he is now. So my question is how much did he beat you by the first time when you were stock? I am just trying to see how much the LET tune helped.

Ya when you get the 185 that should really make it a race then.

lol, i was going to say. That guy must be a horrible driver is he's turbo'ed and only running 13's.

First time I ran him was 1/4 track. His time against me was 13.4. His best that day was 13.0. Mine was 13.7 this was only til 105mph or so as you probably know. However, with his wheel spin I almost get no griping issues on track surface, I think it would be a damn close race right now if we were to do it on a track.
Also my intercooler is leaking, the intake mani has green residue all over the walls and water is my coolant for now instead of mercedes stuff. I'm not using these as excuses, but I'm sure they have a significant effect on my times and performance.

That actually helps you, not hinder you

[CrazyDonkey]

Does the Dinan ECU really not void the warranty? your at just around 40k for a car that easily outperforms the M3 number wise.

Edit: around 40k if you dont load the car up.

[TemjinX2]

i dont think the dealership is really going to be able to tell, short of taking out the ecu or plugging it into a obdii reader.

[CrazyDonkey]

Hmmm very interesting idea.

Doesn't the special MB coolant stay colder longer than water?

Actually, the dealers are WELL aware of the situation with the piggyback ECU's and most are plugging in the cars and reading the boost levels and stuff like that immediately voiding warranties. The piggybacks have that problem I guess.
Would a simple ECU reset fix this problem? I'm not sure. I never seemed to have this issue with the Audi and I was running 23 psi and just put it back to 'stock' mode when I took it in.

+1. Dealers made changes in the 08 models and have updated many 07 ECUs to allow for more readability by the dealers to detect the mods. The tuning companies making the piggybacks, i believe, have in turn adjusted their products to improve invisibility, though obviously it is never smart to bring in the car with the piggyback attached.

With regards to resetting the ECU, I believe that the BMW dealership can detect that it has been reset and it would look awfully strange to bring in the car to be serviced right after the ECU was resetted as the amount of miles and boost readings and everything would be reset. I'm not 100% sure on this, but I don't think it is a viable option for 335i owners.

Perhaps someone is more knowledgeable about that can chime in.

[Jbizzy21]

I had a small conversation about this with someone knowledgable to the BMW workings...The dealers have not just made changes to allow more readbility...in the new models of the twin turbo engine, they have actually put a block on the ECU of those cars, so that you are unable to change it whatsoever...My guy was pissed because he was attempting to boost up his 135i to race in it, but could find no way to do it...this was about 2 months ago so perhaps things have changed since then, but that was the last that i heard about it.

That's horrible! My little brother is going to get an 09 335 and we planned on getting the boost turned all the way up. Where theres a will, theres a way...but the 335 is very attractive since it's so easy and simple to get an extra 100hp out of it.

[SLK55R]

you didn't get a pulley that changes your boost on your supercharger .. his ecu tune changes his boost.

This is not even close to an apples to apples comparison.

Why should it piss you off? The M6,M5 are in a different class then the 335i. So the 335i is quick as the above with mods. You say your M6 is heavily modded. I assume you have a blower in there?

[Jbizzy21]

obviously yes the cars are in different classes. its just frustrating that it is so simple and so cheap to make that car just as fast as ours. yes its easy to do that with a lot of cars, but the fact that it is a bmw and its still that easy to do, but yet it costs thousands to decently upgrade the m5/m6 is very disappointing. guess thats the beauty of FI. and no, i dont have a blower, but have done pretty much everything else u can do to the m5/6 short of a s/c kit(theres only 2 available and they are both in excess of 40g's). ive never heard of or seen a new m5/6 that had a blower in it, besides one in a magazine.
