C250 Coupe Tune available from Burger-Motorsports?
#78
Hey guys:
I noticed that Terry had put up a picture on instruction on how to increase the power settings with the tune that nobody moved over to here. This is what he said:
"If you open up the case by removing the two small screws there is a small dial that can turned using a small flat head screwdriver. Towards the "max" increases the boost gain while towards the "min" reduces it. The adjustment range is around 2.5psi. By default we ship with and suggest the 60% setting as shown. But if you want to increase the low end boost a bit you can turn the dial towards the max setting.
At higher settings you'll notice the car will become a little less smooth at lower throttle angles and it also increases the chance you'll throw a low boost mode (which clears itself when restarting the car). Due to the weak wastegate and diverter valve system the dial will not have any effect on performance over 4000rpm."
Here is the pic he provided:
With that said, I know you guys are saying power is increased in the low-end, and due to the weak wastegate, no peak power gains. But I'm curious as to why the power or 1/4 mile times has not improved - even slightly noticeably.
I'm still going to get this as soon as I collect some cash from my receivables, lol. The only thing I hope we can get sorted out is the intermittent CEL some people are experiencing from overboost. Does anyone have any ideas on how to help prevent this from happening (besides turning down power output in the box). As in, improved wastegate, downpipe, etc. Not too knowledgeable when it comes to boosted cars...

I suspect that the MPG change is not because the car is much less fuel efficient. But because people are beating on their cars to try out the new tune, and because it is more enjoyable...
#82
Can anyone else chime in on their experiences with the tune? I am strongly considering getting it but would like to hear more about what reservations people that already are using it might have.
Thanks,

I am at 80% no issues or CEL/Overboost light. I think this setting is where I will stay until we have supporting mods.

Hey guys just thought I would chime in here for a second. I looked at the intake he is making for our car and ummm, for real? I made something like that months ago and it looks exactly the same you can do a diy of this easy. Not trying to bash on them just saying it seemed like a lot of hype for something that you can make yourself?

The car is a little louder, little better low end nothing drastic. It's just a cheap easy mod that makes the car sound better and have a more enjoyable ride. I can do pics if you guys want but I am not too sure how to post them up I don't really go on forums much. The JB+ is good from what my friends told me and Burger seems alright they just aren't that amazing.
#90
I can't seem to find the forum on the burger site about the C250 progress... Can anyone post the link again?
Also, as far as the cone filters go, are you guys using a heat shield? Otherwise the mod is pointless and would probably degrade performance.

n54tech.com that one? How is the mod pointless? I don't understand why people say that, a heat shield would prevent heat soak yeah, but you are running a cheap short ram in the first place lol. That's why I was saying don't spend a whole bunch of money on it, they should know it's nothing crazy and make it cheap. I didn't see a heat shield on the BurgerT thing on the forum so idk if they use one either.

Personally, doing this mod over what we have stock is negligible at best, the stock setup is probably better, just throw in some green filters into the stock housing if you want and you will have better results. About the only thing this mod may do is a better throttle response, but I doubt air is the bottleneck in our system, it is probably more the drive-by wire safety system utilized.

LOL... There will only be heat soak if you leave the air box uncovered. I have been running short-rams on all types of cars and heat-soak is only valid when intakes are fully exposed to the hot engine temperatures. If you keep the cone filter in the air box covered there will be no problems. That's like saying the stock crap filter gets heat soaked lol.
Topend speed is improved by keeping the filter completely exposed. I do a lot of city driving and will keep the air box closed for better low-end/throttle response.

FWIW I ran a 0-60 test using Dynolicious with the JB+ at 65%. The app is pretty accurate in my opinion, I've used it on other cars and it's spot on.

I've tried many times (stock vs. Race Chip Pro) on my C250 CGI Coupe but I didn't even come close to 7,2 seconds that are stated by MB as for 0-60.

My launch technique was to turn off stability control, left foot on brake, right foot on accel pedal, and once the rpms hit 3k i let go of the brake. There was actually too much wheel spin, which increased my 60' time. If i got it to around 2.2 seconds, my 0-60 mph would have been around 6.3 seconds.

Any idea how harmful this break-accel method is for the car?
