Hey all,

I just got a Microtech LT-8 installed on my GXL. Check out the review and post comments and questions.

C'mon, guys! Comments?

This thing rocks!

Waiting for my MT-8 to be upgraded to LT-8 to do the install . Let us know the dyno results

 

I'm glad to hear something positive. I'll be purchasing one eventually, but not with the group buy. I currently have a weber 48DCOE on the racecar but will switch to some throttle bodies and an LT-8 as soon as the money(wife) permits.

 

Being in CA, my concern again is passing emissions, while still getting decent power... I know people that have done that just fine with the Haltech.

That and the complete lack of tuners in the area, means I drive an hour or two and spend and arm and leg to tune. No fun getting a ECU for $700-$1000 and then spending another $500 for someone to tune it.

I want a system that I can wire in, and have the car run fine, with minor tuning myself, then tweek on a laptop or WinCE device.

 

Well, we always recommend that a professional tuner tune any standalone EMS. Individual users have had incredible success in tuning their systems well enough to drive to the tuner (and maybe more). This is due mostly to the fact that you can do initial tuning in 2D, and get the car runned extraordinarily well. At that point, dyno/professional tuning is only necessary for maximising HP and fine-tuning the edges of the map.

What do dyno tuners do differently that a common user wouldn't? I have seen evil aviator's wolf 3d and his controller and laptop. It seems pretty easy to watch the grid while tuning the car yourself for the optimum a/f ratio.... What does a dyno guy do differently than that?

I'm sorry but I have never been to a dyno and have only seen them in videos. The only reason I can fathom to go to a dyno is so that under load you aren't on the road and in traffic and worried about hitting people while you tune. I could just go find some abandoned road couldn't I?

Well, there are a few reasons a dyno is preferable.

The first is maintaining high-RPM and high-LOAD, and keeping at an RPM point long enough to get a reasonable AFR reading. The only way to do that on the street is to stay at the top of high gears. That means very high speed.

Noise is also an issue. It's hard to hear soft detonation at 140.

The last is what happens if you blow up your car. You may well not have cell service if you're out in the middle of nowhere. Usually a dyno shop is somewhere near a towtruck, if not a full-on repair shop.

There're more reasons, but those are the big ones.

Brandon thanks for the input.

I would think with a good wideband and a laptop you could fine-tune your car yourself. Just get a passenger and start out really rich. Just take away fuel as you go, letting the passenger keep track of the A/F ratios.

 

Yes, but what do you do when you're trying to tune above, say, 7000 RPM? In first and second gear, it goes away far, FAR too quickly to be meaningful. In third gear, you're doing over 90 MPH, and it's still going pretty quick. In 4th gear, you're doing well over 130 MPH. Keep it on the dyno.

So what happened to the dyno results? I am anxious to know how it turned out!
