Kidding! Just playing around with v2 beta today.

The next two photos are pictures of the Terry Tuner v1 production install. Was able to go from an average of 0-60 of 4.62 to an average of 4.35 with the v1 +2psi, 91 octane.

Haha maybe just a little bit? Good luck with the final result Terry.

[j|rz44]

naw, you should be alright.

[RiXst3r]

you really need to get to a dyno

[jonerik26]

oh so that's what it looks like under there...

Jack when are you going to come over for a v1 install?

[A418t81]

LM1 in yet?

[chbrules]

Where in So-Cal are you, Terry?

Looks like things are getting a little messy there! You know what they say, if it doesn't get all over the place, it doesn't belong in your face.... well... car?

Good work!

No, I couldn't reach the o2 sensors under the car so I ordered their tailpipe adaptor. I don't want to weld a bung since it's only a temp setup. It should be here next week. Driving around town the v2 circuit is working and richening the car up under boost, I just need to dial it in with the LM1 and then slowly raise the boost.

nice work man. those 60 times are super low. GL with that v2

Over in Simi Valley.

Smart to black out the VIN.

Good work, Terry ! great numbers !

Always good to have competition. Seems amazing that something that looks sooooo simple, can do what you need it to do. Good work! Goes to show that sometimes the most brilliant solutions look simple, but infact are not. Have you noticed any sluggishness at lower RPMs? Any problems with boost targets not being met (doubtful since only a 2psi increase)? Any problems with hard starting? Does the power come on linear or just a big wallop of torque pie at 4K RPM?

I'm really happy with the v1. The install is clean, drivability is stock, boost is smooth, and it makes great power. No sluggishness, no codes, no hard starting issues, etc. Just a nice kick in the pants across the board. It's amazing that something so simple can make such a profound difference, but big props to BMW for making an easy to modify car.

I suppose if I were a marketing person I'd put it in a box to hide how simple it is, hype up how much R&D it took to develop, and mark the price up 500%. The funny thing is it’s actually easier for me to access the ECU and put this in than it is to reach the turbo tuner clip. Go figure.

The v2 needs work. Since I don’t have the wideband in yet I set the AF ratio overly rich, around 12:1 in the midrange and 11:1 up top, and at 10 psi it feels a lot slower than the stock AF targets at that same boost level. Once the wideband is in I’ll lean it out to around 13:1 in the midrange and 12:1 up top, and then slowly raise the boost until knock retard becomes an issue. I’m hoping to get away with 12psi / 330rwhp.

How do people who don't tune cars for a living get a sense of what will harm an engine? I'm a complete moron, and have no knowledge when it comes to tuning cars. I've heard discussions about the variables your working with, and it all seems reasonable. What are all the other shenanigans (sp?) Vishnu and AA doing?

The difference is that Vishnu and AA have done it and Terry tries to do it. Another one is that Vishnu and AA have a lot of tuning experience, especially Vishnu on that specific car. 2 Vishnu PROcede'd 335i's sustained a 12h endurance race, one of them won the race. The cars had bigger oil-coolers and the AC equipment removed to enable full air flow to the radiator. Special PROcede map. Exhaust without cat's. LSD.

I’m sure it varies greatly depending on the experience and educational level of the tuner, but all tuners rely on control systems to tell them whether they’re “hot” or “cold”. Scanning software, wide bands, dyno, etc, serve this purpose.

A bad tune will break an engine quickly. Assuming the tune is good (which you determine with the control systems), it’s impossible to tell how far you can push the package power wise until you break something. Shiv can’t tell you how much HP he can make before the head gasket or something else will blow out. AA don’t know how much boost the turbos can make before they start to self destruct. They’re going to have to break a few parts first, and breaking parts is bad for forum marketing. =)

Hey I'm not a shop or anything but I know my way around.

I'm sorry but every time I hear about the 12h endurance race I just roll my eyes. It's a great footnote, but in reality it doesn't prove anything, unless having your engine survive 12 hours with larger coolers and race gas is the criteria for modification. Most people around here seem to care about making it 10k, 20k, 50k miles using pump gas and normal coolers.

It's 12h reliability proof under race conditions ahead to the others, isn't it ? For me this says a lot about the knowledge of the tuner, well aware about that our cars are not 1:1 comparable to those used in the race.

Was there another 335 in the race that broke down? Did other modern cars not finish? To me it says more about the 335 itself than the procede.
