So, I have been battling boost control issues for a few months now. After my hatch back was tuned last November it ran great for a while. Then, gradually I started having issues with the electronic boost control that is managed by my Hondata s300. The initial symptom was the car hitting boost cut instead of the boost stopping at 20psi and holding like it should. If I went full throttle the turbo would just spool to the moon and never stop, very annoying. I was able to “fix” it briefly by lowering my boost solenoid duty cycle in the Hondata Smanager software but it did not last long. Gradually it would go bad again and not hold boost, once again shooting straight to boost cut and the wastegate would never open. After much troubleshooting and testing that did not get me anywhere, I decided to try a brand new boost solenoid from Hondata. After I put in the new solenoid everything worked perfectly fine again! So, on the surface it seemed that my old boost solenoid just went bad or maybe got damaged from heat. Well, not so fast, as my over boosting problem returned only a couple weeks after I had the new solenoid. Back to the drawing board…again after more testing and troubleshooting I did not get anywhere. Luckily I got a tip from a member of d-series.org about a possibility that the filter on the front of the solenoid could be getting clogged up and not releasing air fast enough. This filtered port on the solenoid regulates the air pressure in the top chamber of the wastegate, and if it gets clogged up it cannot release air pressure fast enough causing too much air to get stuck in that top chamber. What happens then is the wastegate never opens, and magically you have no more boost control and will over boost. So, with that tip, I unscrewed the filter cap on my solenoid, said a prayer, and took off driving again. Much to my amazement, the boost control was working again, yay! So after weeks of fighting my boost control issues, and 2 solenoids later, the problem was solved by simply taking off the solenoid filter. Why both my filters got clogged up so quickly I’m not quite sure, although they seem pretty restrictive to begin with, I guess it doesn’t take much to make them worthless.

Recently I decided to get back into paintball. After not playing for 5-6 years or so I got the itch again. At one point I travelled for tournament play for amateur and professional paintball teams playing in the NPPL series (now defunct). Anyways, here is a couple pictures, blast from the past and also my new marker setup. An 07 Evil Minion, Pure Energy 45ci/4500 tank, and DXS Pulse loader…I have a few more things coming but this it for now.

Well, here we are again, another site update. This time it should be pretty persistent and the only changes may be to the looks in the future. Hope our 3 regular visitors enjoy!

Well I’m headed back to Japan. I will be checking out the 2009 Fukuoka Auto Salon among other things. Pictures and info will be up early February.

I got down to Colorado Springs to see my old friend Jeremy of http://serviontuning.com Servion Tuning this past weekend. Everything went great for the tuning session and he was able to get some great power out of the car on 20psi of boost. We stopped there to avoid risking damage to the engine since the cylinder head is stock still. Once I upgrade the valvetrain and cam we will retune and take it even higher! Check out the youtube video of the dyno pull here!

Ever wonder if you could sync your Mac Address Book to Gmail Contacts? Well, I did, in recent preparation for my new G1 Google phone that is in the mail It is a fairly simple process, it is easier if you have previously connected an iPod/iPhone/PDA or some type of handheld device to your Mac (because you’ve already setup iSync most likely). I followed the instructions here, How to Enable Mac Address Book to Sync with Google’s Gmail Contacts. It mentions using the command line to edit the plist file, but there are other GUI alternatives like PlistEditPro to make things simpler. In short the steps are:

1. Backup your Mac Address Book!
2. Modify the “~/Library/Preferences/com.apple.iPod.plist” file (if necessary).
3. Open Address Book settings and check the box to “Synchronize with Google”
4. Open up iSync and click “Devices -> Sync Devices”, or enable menubar sync.
5. Wait for sync operation to complete, then login to your Gmail and verify the new contacts show up.

All in all it works out pretty well. I have encountered an issue if you connect say an iPod to your computer and sync iTunes, it will overwrite the changes you make to the “com.apple.iPod.plist” file. While the link I posted above says how to remedy that situation I could not get it to work myself. Here are a few additional screenshots to show the process.

So, some months have passed and recently I have done some changes and fixes to my Civic hatch. After driving it for a while I felt like the turbo I had was a bit too large for the application, with the power coming on really late in the power band. I opted for a Bullseye Power t3/t04e 50 trim with a .55a/r turbine to replace my MasterPower turbo. This turbo spools a good bit sooner and faster as well. I have not driven it that hard being that my tune is off now but I was able to get a good idea of how it performs. My old Greddy bov also blew it’s diaphram and was leaking bad at the mounting flange, so I decided to upgrade and replace that with a new Tial Q bov. A new catch can was also installed recently. Finally, my boost solenoid is also about to get installed so I’ll have boost control. Plan is to get more tuning on high boost settings in 2 weeks. Stay tuned!

My Civic hatchback is back on the road, after a fresh tune on e85 and ~7psi of boost. It made really good power, 215whp/175ft.lb. torque, but it does not come on until real late in the rpm range. Looks like the turbo is a little too big for the setup. But, I am going to wait and see how it looks on higher boost settings. If it doesn’t turn out the way I like I will probably change to a different turbo and get re-tuned. Overall though I am enjoying the car, it still has some minor issues that need to be fixed but I at least have it back on the road.

Turbo installation is underway, but not before I had to deal with some other problems. I had to start the weekend (last week) by dropping the transmission to replace the main seal that was leaking. What a pain, twice now I have pulled and re-installed a transmission by myself, without proper tools or lifts/jacks. DUMB! Anyways, to the turbo install, I got the fuel system done. New in-tank Walbro pump and some RC1000cc injectors, along with a new liquid filled fuel pressure gauge. After that I got to installing the manifold, wastegate, and downpipe. Here I ran into some more issues related to fitment with the wastegate and downpipe. I’m working on getting those fixed up so for the mean time here are a few pics of the progress so far.
