a dyno is just a tool- it enables you to tune more combinations of load and rpm than you could ever do on the street -if it's used properly-. sadly, i've rarely seen anyone tune anything other than WOT on a dyno (and a lot of dynos can't even do that accurately wrt how the car runs on the street. just because you have a hammer, it doesn't mean you are a carpenter

 

So the 6.5 TME 10.5 16g that I replaced my old VIII 16g w/9.8...not worth it??......assuming I am never to run anything higher then pump gas...??...

 

I wonder if the squirrels in my yard will be donning these in the spring:

 

i'm going by what i read and speculating about the possible reasons. also, the compressor wheel and exhaust wheel that you use in the turbo will also factor into what is best for a hotside size. fp was also talking about their fp evo green turbo, specifically, so there's yet another variable in the picture.

the 6.5 TME has a better compressor wheel, though (titanium aluminum) so you will get better response than the VIII turbo (less rotational mass).

 

...and this is why I am starting to ask questions. Its easy for me to:
1. call said tuner
2. make appt
3. show up for tune
4. give them $$$
5. drive home
6. Hope to feel the difference, and if so, know that I am safe everywhere in my maps.

ECU is a completely new language to me. I just need to learn it.

 

it's tough- i chose to learn it/do it myself, not because i think i am better than anyone else but because a) i'd know if something was halfassed or not done properly and b) it someone was going to my **** it, it was going to be me .

i think the key is trusting whomever it is you chose- a least in the subaru world, there are literally a handful of people who i'd trust my car to. not saying the others are bad, per se, but i wouldn't feel good about it. i've written off shops because the tuners were arrogant. there is some art to this, but really it comes down to physics. it's not like engines are magical- the combustion motor has been around for a longass time and despite various improvements (VVT, direct fuel injection, electronic spark), the idea hasn't changed much. the key is to understand what you want to accomplish and understand the ramifications of what you are changing. also, making sure the changes are giving the desired behavior is important.

i think the best advice i've ever heard is from Christian@Cobb- 'Do what makes the motor happy' When you know what to look for, you can tell when the motor is unhappy, either from incorrect AFRs, too much boost, poor timing maps. If you don't force the car to do something it doesn't want to do, you generally won't break something. It's when you try to force 400 whp out of a setup that only wants to make 380 that you find things go awry. That motor won't be happy [for long].

 

that part depresses me. the best thing about the dyno is being able to dial in pretty much any load-cell, but what tuner actually takes the time to tune a large portion of your map? *sigh*

 

I am touched by all the value added posts made today. I really need to start experimenting with tuning my car. I have been reading a lot and I think mikie can attest to the countless coversations we have had on the matter but it really comes down to just taking that first, uber conservative step and making some changes to some maps.

this talk makes me horny to get out there and tune. to bad the weather is negating that want.

 

Agreed. I can't wait to finally be able to do some tuning...Still need a WBO2 though. I think I am going to fix my car next week, as long as the gaskets are in. I can use my future sister-in-law's garage so I can take my time as well

 

Is the ZT-2 a failsafe or just the WBO2? It seems the ZAVT is what TTP pushes - and that is just an audio/visual alarm??

I already have a wideband - Innovative XD-16 w/ LC-1, wondering if it's worth it to switch to a WBO2 setup like TTP recommends.

I would like to stick to pump, but I'm tapped out as far as pump gas mods on the stock turbo...I need more power and alky seems to have the best bang for the buck, nevermind that you are seriously handicapped for any step you take forward turbo wise.

 

He was talking about the evo 8/9 specific alky kit I have made.

I don't need megasquirt because of a few nice guys on here have given me the ability to utilize the stock ECU to take care of everything I basically needed with adjustable LOAD% on/off points, multiple failsafes, including alternate fuel maps and boost map switching if any failsafe is triggered. This system is designed using a single alcohol safe fuel injector (not for use with water) and is directly controlled by the same pulse width as the stock injectors so its always a perfect ratio of gas and alcohol injection. You can dial in the alcohol/gas ratio from 30-40% alky and the best part is....its ALWAYS that ratio! Not like the alky kits which aren't quite as exact as boost and rpms change. So far it has fuel pressure monitoring, fuel flow monitoring, protection if a system leak is detected and protection is the fluid reservoir becomes low.

We are currently working on a failsafe that hooks up to air/fuel monitoring from a wideband 5V linear output trigger (zeitronix has this for example) so if the system goes leaner than a desired level while over a specific boost level or throttle point the safer maps get triggered. When using 93 octane gas, the system will increase your effective AKI octane rating to 100 octane (R+M/2 method). Between the octane increase and cooler air intake temps from the injection process, this system has many advantages over a universal water/alky kit.

And it has a separate LED display panel that can be mounted on the steering column, dash, etc... which alerts you of any failsafe triggers (and which trigger it was), lets you know you are running on the safer fuel/ignition/boost maps and even has an audible alarm buzzer (except when its in the alternate maps because of a low fuel level in the reservoir).

If any of you guys in the RI/MASS/CT area and are interested in beta testing this setup, PM me for details.

 

yea i think i want it. how much is it?

 

Honda paul-

did you end up going out?

i am heading to sleep. very inebriated.

actually i think i will just sleep on the couccch because i am here already.

i'm on my couch. being drunk.

see you *****es tommrrrrrrrow!

 

It was easy

 

i didnt even go back to my place till like 8 then d3xt0r ended up headin out and we just grabbed some food and a couple brews. what are u guys up to today?
