Guest TurboSedan Posted November 17, 2005 Report Share Posted November 17, 2005 unplugging the ECM controlled wastegate will give you max boost and it will spool up as fast as possible. very very dangerous....i wouldn't recommend doing that. some guys are getting away with it at high elevation, but they still bleed off some of the pressure (or else you'd hit fuel cut). i myself don't have the balls to try it. you could go with a MBC like i am using that essentially does the same thing...it will spool up MUCH FASTER but you can set your maximum boost level with that to avoid engine damage or hitting fuel cut. they are cheap and very easy to adjust. although if you have an automatic i still wouldn't recommend it. maybe track only.

Guest TurboSedan Posted November 17, 2005 Report Share Posted November 17, 2005 where is it at? MBC mounts between the fitting on the compressor outlet and the wastegate can. you will need a boost gauge to adjust it. a narrow band A/F gauge would be good too.

qmtgp Posted November 17, 2005 Author Report Share Posted November 17, 2005 lol i meant the ecm, a a/f guage is just a light show they dont work, you need a wide band 02 to do any tuning. so if i get a mbc i can just turn the boost up?

LukeZ34 Posted November 17, 2005 Report Share Posted November 17, 2005 Sure, but if you have an automatic tranny you lose all the saftey controls that the stock boost controller uses. So unless your looking for a reason to kill your 4T60, I'd refrain from doing it. Quote Link to comment Share on other sites More sharing options...

Rocketman Posted November 17, 2005 Report Share Posted November 17, 2005 I've got a AFR gauge on my turbo Capri. Sure, its a light show when the ECU is in closed loop but it does it's job when you are under load. If you have it floored and it migrates into the lean region you've got a problem. Dont put narrowband down unless you've used one. Quote Link to comment Share on other sites More sharing options...

So unless your looking for a reason to kill your 4T60, I'd refrain from doing it. yeah it's an auto , but my tranny is very well built so i guess i'm not to worried about it, "unplug the computer from controlling the boost and tire smoke in less than a second" "unplugging the ECM controlled wastegate will give you max boost and it will spool up as fast as possible" is it where the 2 vacume lines are goin to the wastgate actuater and the one for the boost guage? cause that's what i seen when i put on my talon 1g bov last night.
