Re: Whats new with Teh Gheyrod...
 

I'm done power modding, its now time to focus on proper balance. I'm going to a new suspension setup in a few weeks (GSR KYB shocks, Swift Sport springs, and possibly a Whiteline Roll Center Kit) and will be upgrading my brakes (RacingBrake ET500 pads, SS lines, and ATE Super Blue fluid). Eventually I'd love to add more chassis bracing and a lightweight driveshaft.

Re: Whats new with Teh Gheyrod...
 

You should see about replacing steel parts with aluminum ones after the suspension.

Re: Whats new with Teh Gheyrod...
 

The Evo body and suspension already has a fair amount of aluminum which is nice. There are some heavy cast iron pieces in the back, but I don't really want to make the car any more front heavy than it already is.

Tonight I fixed my wideband and tightened my throttle cable; tomorrow I plan to replace my cabin air filter and install an AIT (air intake temp) sensor in the intake manifold. I of course forgot to get an ECU pin so I'll need to tap into an existing wire so I can log the temps.

Re: Whats new with Teh Gheyrod...
 

Well the GM AIT sensor in the intake manifold is working perfectly, but my GM BCS took a crap or something because I've pretty much lost all control over my boost. I guess I'll be picking up a DB MBC tomorrow when I'm out there for a Shane-tune. Probably for the best though, I've never really liked it since I got it and its always been more hassle than its worth to me. I think I also damaged my EGT wire when running the AIT wire because the EGT gauge no longer is working. Damn it!

Re: Whats new with Teh Gheyrod...
 

Broken EGT: I blame it on the new cabin air filter!

Re: Whats new with Teh Gheyrod...
 

I got retuned today and am so happy its amazing! I've been having a lot of issues with the GM BCS/ECU-controlled boost so I decided to ditch it and got a new powdercoated black MBC from DB while I was out there today. Shane also mentioned this is the most powerful Evo with stock turbo on pump gas that he's done :D
I'll let the dyno charts speak for themselves; the change was quite impressive.

Red/blue = retune with MBC
Green = as I came in with GM BCS

New whp and PSI
Nice and smooth boost curve with a conservative 24psi!

New whp and wtq
Nice fat powerband with a lot of area under the curve!

Another interesting note to add, my Perrin FMIC is doing a wonderful job, as is the intake manifold coating and barrier gasket b/c my air temps inside the intake manifold are lower than the temps at the MAF.

Thanks again Shane!

Re: Whats new with Teh Gheyrod...
 

I can't believe how different the bcs behaves on they dyno vs the street. I'm glad you switched back to the MBC though; I was getting sick of hearing you whine about the thing ;)

I like the powerband on your car; its sooo phat! Its a wee bit of a shame your top end isn't better, but I think its obvious that the limit of the stock turbo on pump gas has been reached. This powerband shall serve you well for a long long time! This is a nice safe, conservative tune.

Re: Whats new with Teh Gheyrod...
 

Agreed on both counts! I was sick of complaining about the GM BCS because it never worked properly and I think this power level will keep me satisfied for quite a while while I focus on other aspects. The two main draws to the GM BCS for me were quicker spool and more power on the top-end, but on my car neither proved to be true. Spool-up is the same or slightly faster with a MBC, part-throttle boost response is much quicker with the MBC, and as we know my car did not respond favorably to holding more boost in the upper RPM range.

Although I don't think the GM BCS is a "bad" mod per say, it just wasn't a proper mod for me. My car saw no gain in being able to hold more boost in the upper RPM's since it seems to prefer timing up there, and boost is a lot more steady and consistent with the MBC. Plus, its much easier to adjust now. I'm still glad I have the JDM MAP sensor though and have no plans of selling that since its nice being able to log boost. I'll probably go ahead and plug the stock BCS back in for now so I can sell the GM BCS and not get a CEL (until I figure out how to safely disable that in the ECU).

Lol, I was telling Scheides earlier while his car was on the rollers that he should slap one on his car.

An old-tech $35 part schooling a fancy pants electro-trickery gadget :lol:

Re: Whats new with Teh Gheyrod...
 

Amen. MBC's are so cheap, and they just work. I'll never run anything else.

Re: Whats new with Teh Gheyrod...
 

Same here..although my DB controller failed on me last dyno session I had..so I got teh basic hallman MBC..hopefully won't ever need another one again!

Re: Whats new with Teh Gheyrod...
 

Not bad! But I gotta say, no MBC and a rock solid 20-21 psi FTW ;) haha

Re: Whats new with Teh Gheyrod...
 

nice power.

Re: Whats new with Teh Gheyrod...
 

24 lbs before 3100rpm is spooly good.

Re: Whats new with Teh Gheyrod...
 

Awesome results dude!

I feel like the car has more top-end in it somewhere, but I'm sure its probably just because then stock turbo is beyond maxed.

Re: Whats new with Teh Gheyrod...
 

Hmmm good. I agree with floppy.

Re: Whats new with Teh Gheyrod...
 

I installed some Swift Sport springs and nearly new KYB IX GSR SE shocks today.
