awesome (IMG:style_emoticons/default/beerchug.gif)
Which turbo project will last longer before blowing up, Mike B's or McMark D's?? (IMG:style_emoticons/default/biggrin.gif) Have fun (IMG:style_emoticons/default/driving.gif) PS - Sir Francis Drake Blvd through West Marin was just re-paved. No lines painted yet...still some construction. I'm hoping to inspire a West Marin 914 weekend cruise loop as soon as it's done. This is all part of Excellence Mag's various "test loops" as I've seen local landmarks in many of their photos. It's been epic fun now that it is no longer pot-hole riddled crumbly road (IMG:style_emoticons/default/shades.gif) |

Did you ever figure out what happened? kinda kicking myself that I didnt want to drive it. Maybe next time I come up I will ask (IMG:style_emoticons/default/confused24.gif)
I know I will be up in the area for some Vintage Racing in Sonoma, hopefully some of you guys will be there as well! |

I blew a fuse that operates the wastegate solenoid, O2 sensor and MAF. Not sure why. When I replaced the fuse, the ECU is holding the WG solenoid open all the time. Not allowing any boost to build. When I saw you, the fuse was blown so I had too much boost without the MAF or O2 working. I can't believe I didn't blow up the engine. So the car has been sitting for 2 weeks with the battery disconnected. If the ECU will not work the solenoid, I may put in a manual boost control until I can either swap out the ECU or repair it. (IMG:style_emoticons/default/sad.gif) I will play with it this weekend and see what happens... |

Given your experience with aftermarket ecu's are you still happy with running the factory computer? Seems like a lot of drama

Given your experience with aftermarket ecu's are you still happy with running the factory computer? Seems like a lot of drama When it runs good, it runs better than any aftermarket system I have tried. At low or no boost, it runs like a stock Audi. Perfect! When the boost comes on it runs like a raped ape! As much drama as it has been, the car only spent about 4-5 hours being tuned on the dyno. Compare this to an aftermarket system and the benefits show. Most of us don't own a dyno so with an aftermarket system you will be tuning for days, weeks, months and it will still run crappy in certain areas. Most aftermarket ECU's look at hundreds of variables per second. Factory ECU's look at thousands per second. Driveability are big issues with aftermarket ECU's. Poor Jim with his Microsquirt can't get rid of low rpm bucking. I can idle forward and feather into the gas and the car runs smooth as silk. So far the cost is about the same. I'm into the ECU and injection about $2k. An aftermarket system will cost you about the same after you buy all the peripherals. So I had a phone call with my tuner on the way home today. After some phone call troubleshooting, it sounds more like I popped an intake tube off or torn a silicone coupler. The WG spring is 10psi. If the solenoid malfunctions I should see 10psi boost minimum as this is the pressure of exhaust that will push it open. I am seeing 1-2psi max which is more indicative of an intake leak. I have some piping that is really hard to get to nor can you see it. So I will have to remove some parts to get in there and look. When the fuse first blew, it was spiking boost over 30psi, so it could have esily popped a tube off. I will know for sure this weekend... Stay tuned... (IMG:style_emoticons/default/biggrin.gif) |

I agree it sounds like you popped a hose. When did this happen?

Well a nice 30psi spike would definitely cause some popped hoses...
Why did you swap the 5 speed back in? Issues with the 6spd? |

Mike, didn't I see a Haltech Platinum ecu in the trunk of your 914, when you were down in L.A. ?
Or was it just an HECU-1 coil igniter ? Marty |

Well a quick look at the tubing and it looks intact. (IMG:style_emoticons/default/sad.gif) I'll have to look carefully for a ripped silicone connection.
If the tubing is OK, that leaves a stuck diverter valve or a bad turbo... (IMG:style_emoticons/default/dry.gif) |

If the tubing is OK, that leaves a stuck diverter valve or a bad turbo... (IMG:style_emoticons/default/dry.gif) Smoke Test? Not that kind. (IMG:style_emoticons/default/slap.gif) I'm starting to think my WG may be bad. If you go back a couple pages you will see my WG had fallen off and was dragging on the ground. For about 10 miles on a twisty road! All I did was fix an adapter fitting and bolt it back on to see if it worked. It did and I drove it until now. I have a new WG sitting on the shelf waiting to be used. I think it's the WG since I'm running a Forge DV in semi-blow mode. If the DV was bad, I would hear it whistle. All my intake tubing looks intact. All my silicone fittings look intact. I'm going to pull the WG and see if the valve is stuck open. The valve may be bent from all the road rash... The turbo still spins freely and when I turn off the engine, I can hear it spin down for some time before it stops. I think it is probably good since I never heard or felt a problem. I have to think if the turbo had a catastrophic failure, I would know when it happened. Since no FOD entered the intercooler and the exhaust still spins it, 90% chance it's still OK. |

The turbo would make a noise, dentist drill or similar or sound like an exhaust leak.
Forged DV's really dont go bad. It makes perfect sense for it to be the wategate that dragged on the ground (IMG:style_emoticons/default/smile.gif) Those turbo's dont just up and go bad instantaneously unless something comes in the intake and its the blades. |

Exactly! FOD would have to get through my air cleaner and MAF grid first. Turbo makes no noise at all. |

There's you problem right there... (IMG:style_emoticons/default/tooth.gif)
The Waste gate broke! The two halves separated and all the exhaust pressure was going out the WG. no spring pressure at all... (IMG:style_emoticons/default/wavey.gif) (IMG:style_emoticons/default/headbang.gif) Looks like it took some abuse but it was enough to start the self disassembly process. (IMG:style_emoticons/default/biggrin.gif) Here is the one I had sitting around. 38mm water cooled JDM POS. I have had great luck with the WG vendor so hopefully it will last long enough. This one was bolted on with new gaskets and high temp thread locker. |
