Power lost while shifting gears. Help

Javi335 · 05-02-2010, 01:20 PM

Hi all.

Well, thats just the problem. Got a borrowed JB3, when i shift on high revs i get a great "empty" between gear and gear.

Anyone have experice this issues?

mkPOTO · 05-02-2010, 01:23 PM

can you explain more, thats a very vague description. Is there no pick up after you shift and hit the gas, or is it the time between shifts?

Boost leak?

Get a BT Scan tool and run a scan.

BoostedCosta · 05-02-2010, 01:26 PM

sounds like a bog....
shift a little bit earlier

Bimmer This · 05-02-2010, 01:45 PM

if you shifting pretty high up in the rpm's, sounds to me like the turbos are just running out of breath.

themyst · 05-02-2010, 01:58 PM

nah, that's a bog or throttle closure. lower the RPMs or bump the bogfix setting.

cstavaru · 05-02-2010, 02:18 PM

It sounds like the bog everyone was talking some time ago.

Even better, i put some vids

Here's on Map 7 changing almost redline and faster i can. (please dont pay attention on the race itself but on my car

)

On that one, Map 7 again, and like some mates say i do it at 6700 rpm, less agressive on the shift and the thing improves.

But, how could be that huge difference on 300 rpm?

Bro what the hell is pulling on you a prius!..... .WHatever lol if you 6mt stop shifting so high shift @6000-6200 if your AT then try the same i could see it in the video your just boging.

U mean what car? is a Seat Leon Cupra chipped by Revo, Stage 2.

What the hell is bog-boging?

Mike@N54Tuning.com · 05-02-2010, 02:43 PM

Lots of possible causes. You would need to update to the latest 2.0 firmware then do a datalog to determine what the problem is. Then there are some settings in 2.0 you can use to help resolve it if its a boost related manual transmission shift bog.

Javi335 · 05-02-2010, 02:47 PM

ok, i googled some and i get it. Sorry if meanwhile somebody was answering. And thanks all for you help.

With bogfix, boost jumps quickly below target ready to rock the next gear as soon as you mash the pedal back down. With the latest R8.3 beta BMS has tuned the JB3 to hold more boost through the shift as well, really rocketing you in to the next gear. All in all fun stuff for us manual drivers

Javi335 · 05-02-2010, 03:47 PM

That thing is a Seat Leon Cupra with ECU flash by Revotechnik and a few thing more.265 hp stock, now thought about 300. Less weight, short gears ... its a pretty fast thing, probably the "best bang for buck" for a whole car in Europe. Is FWD.

Seat is now under the VAG empire, back in the time was 100% spaniard factory. The engine is the same you find in others VAG cars, like the Audi S3 or TT.

Alessandro · 05-02-2010, 06:17 PM

There is no way a seat rev2 can hang in with you on Map 7 if you are running as it should be. Can you let me know your mods? what else besides Map7?

Also try to shift a little bit slower it will help as well and also update to 2.0 ASAP.

Youre right, while the Leon his chipped, DP, IC etc i only run with the JB3, im was just testing it, the rest of the car is stock. Plus, 98 oct fuel, 19 inch wheels ...

AltecBX · 05-02-2010, 06:56 PM

You have to calculate the difference in Weight = HP (Leon=3110: 335i=3580). The car is much lighter than a 335i and uses a similar 2.0 TSI engine that AUDI has. You might need to produce another 20+ HP to keep up with him.

Are you bumping on your speed limiter while doing these runs? I know those Leon have a speed limit of 147 MPH and 165 MPH when chipped.

You need to play with the bog fix settings on 2.0.

Its a pain to do, some people get lucky.

If your not on 2.0, you cant adjust and you're stuck with the bog between gears, especially on hard shifts.

People talk like its easy to just "ease" into the shift to reduce the bog, but you shouldnt have to do this, it should just work correctly. My .02./
