Title: Timing cut instead fuel cut
Post by: walter on December 14, 2009, 04:20:48 PM
Is this possible using TE or Crome?

i saw some threads talking about antilag, i found this device, BeeR rev Limiter, that cut timing instead fuel cut, and i was wondering if that shuold be possible make samething with TE or crome.

 :noel:

some vids of Beer Rev limiter.

Ther is a trick with Crome to get an antilagish thing going on search

No trick necessary if you have Crome Pro, although none of this relates to this thread.

i have always wondered if someone with more programming abilities than myself could modify crome to cut ignition rather than fuel

Antilag is a long walk off a short peer for your turbo.  This has been discussed before.  Know what your getting yourself into.

i was under the impression he just wanted ignition cut and not anti lag

Ya know that's what youd think. I did. However when talking to am actual honeywell/garrett engineer last year about why I may have been seeing random smoke and mentioning antilag and that mine is pretty nasty he dismissed it.

No flameballs no care. I need some video of my antilag and the dashboard trying to flex its way out of my car  :noel:

You have a problem with oil temp vs oil pressure.

Have the antilag conversation with a Garrett engineer, but state that it's a rally car.  Their tune will change as those vehicles exist in antilag when not WOT.  Well, not when the oil smoke is intermittant, but they'll have something to say about it.

That's interesting. It seems like you would want good throttle control with a rally car since there are changing traction conditions and drifting.

He meant between shifts.  The flutter/compressor surge they are known for is part of the timing retard function of the antilag w/o the fuel.  Those systems work by looking at load, when you have the throttle open (not wot) and load starts falling, antilag kicks in.  Its smarter than that but you get the picture.

We did get into a conversation regarding shaft speed vs the"seals" ability to do its job.... raising the idle 150 rpms seems to allieviate the  issue. But I could understand what ypu were saying being relative to  that as well

that system is used in WRC , faggot and it's something like antilag, antilag you use in crome , you try to retard a lot and put more fuel, with this shit, you dont get spark and get fuel, almost sameshit.

Rally cars are something altogether different from other race engines. Many will run in alternating half-cylinder mode near zero vacuum. They flow more air into the turbine, inject the fuel, but only ignite half of it in the engine. That's one of their sort of anti lag, keeps the turbo spooled for instant response.


If you do a timing cut redline limiter, you'll run into major issues once your power is high enough. Very late ignition can allow for detonation at peak cylinder pressure, but you're still making enough power/flow to keep revving. Ignition CUT is where it's at. I can't tell you how many small children I've made shit their pants on the city sidewalks with gunshot-like reports... It was also funny on the dyno, everyone thought they blew up my car.

I almost killed my turbo the first time I used antilag in eCtune.

The shaft was stuck or I don't know what. Reved the engine to the sky on the highway and finally started to boost again.

Antilag in eCtune is serious business!  :noel:

chances are you just sucked a poutine into the turbo.  it was hungry for greasy cheese potatoe gravy.

Maybe you are right, that would explain the smell.
