Seattle E63S

Does anyone have any experience with CarBahn’s flash on our E63? I had a lot of Dinan’s prior mods on BMW’s and they all performed flawlessly so I assume this would be no different. Not the biggest numbers but usually a very OEM+ type of upgrade with terrific reliability. Anyone with the tune that can speak to the positives/negatives?

I will be watching this as well. Dinan products might not deliver the highest power numbers but they are always reliable.

Nice to see more players in the game!

Had a Dinan tune on both my e39 m5 and f10 m5 and never had a single issue.

Any news?

Seattle E63S

I ordered it. Will report back after I install and drive for a while. I’m stoked!

Im assuming this is flash only, so if you have intakes and dp they wont be tuning with these mods in mind?

Seattle E63S

That is correct.

$1299 for a tune and handheld is the best deal on the market. 680hp/730tq is pretty good, too. It's not too far off of the other vendors $2k+ tunes. Interested to hear how it performs.

C2 Turbo

This is what I am talk'n about too. I don't want to squeeze every single drop of power out of the engine and it's OK to leave some powa for the sake of reliability.

Mojo20032004

Which would put it around the 564awhp with the 17%
drive train loss..seems low

C2 Turbo

Its the torque curve ithat seems pretty impressive with enough power to enjoy the car with all the safety parameters in place?

What do RennTech and Eurocharged put down?

Mojo20032004

My car in stock form put 510awhp..not bashing the company and all, but Dinan has always been known to make less power than its competitors. I personally feel a custom tune for each vehicle is the best route to take, especially if additional parts are being added to take advantage of improved air flow being with intakes or downpipes

C2 Turbo

Really don't want to do the Intake with who knows how muc the high flow of bad air be contributing to the engine issues. So with EC what did you put down?

Mojo20032004

Goes in Tuesday for tuning, will find out

And how is it bad air when it's a sealed system since it seals with the hood closed? And logs show turbos don't have to work as hard

Good luck, looking forward to reading the post drive report.

Steve's approach to performance is educated and refreshing, just hope he gets around to the W213 engine for E63s models.

C2 Turbo

I am just guessing the quality of outside air, what I meant. Yes there are filters but I think those high performance filters might not be filtering what they are suppose to filter/

JonM

Renntech and Eurocharged "stage 1" stuff are basically the same numbers as this tune.

Renntech +: 669/734
Eurocharged: 667/760
CarBahn: 682/732

Honestly, within a few numbers of each other. I wouldn't be surprised if they all put down +/-15hp/tq of each other on the dyno. ​​​​​​ Of note, the CarBahn tune claims the highest HP.

Mojo20032004

I mean if someone is after a flash only tune it's a killer deal no doubt even if it is 10-15hp less than the next competitor, but with that price tho, and real world experiences, should be a success

JonM

With the handheld it's about 1k cheaper than the next competitor with a handheld. Definitely a deal, and seemingly worth it. I might buy in.

The1stWright

Can't wait to see how you feel this tune works.

C2 Turbo

So MOJO just had his car custom tuned with DP's/Intake etc and if you consider 15% drive train loss, his numbers equate to

EC/DP/BB Intake-Custom Tune: 700/769 a gain of 18 HP/30HP , Impressive, not sure!

Would I spend money on DP's ($1300) + BB Intake ($1600) + Base EC tune $ 1700 + $750 custome tune + New Plugs ( $$$$) + New coils ( $$$$) = $4400 + to gain 18/30 power, definately not.

Am I missing anything here?

Mojo20032004

There are so many variables to this. Carbahn numbers are crank numbers(flywheel horsepower as noted), not wheel. A custom tune will be Taylored to the specific vehicle with the current ethonal that's available and temp/humidy as well. My car will run perfect at 60-80 degree Temps VS a car that's in Vegas running at 90-100 degree because your tune isn't dialed in for this Temps. Your off the shelf tunes(any manufactor that makes of the shelf tunes) doesn't take this into consideration, so it won't run at its full potential. I gained over 100whp from 3 mods that are specifically tailored for my car. I'm pretty happy for that. Coils and plugs are a must when u decide to tune. Stuff wears out faster and needs replacing sooner. My advice dyno ur car stock, dyno after tune and see your actual gains.

JonM

From what I've seen, a DP and BB intake car should walk a tune-only car. It's proven to put you deep into the 10s, where a tune only might get you 10.9. If you want that extra 0.1-0.6 seconds in the 1/4, the extra 3.5k might be worth it. For everyday street driving, tune only would be better for longevity and wear and tear. It's all personal preference.

Now, in my opinion, if you only want a tune, this option seems to be the best of both worlds: inexpensive, and comparable results to any other tuner. Guess we'll see. What we really need is somebody to dyno tune before and after they get this to really see the results. Or maybe use a draggy.
