Turboge,

Here in pittsburgh, it can go from 30-40 degrees, to 7-80 during the spring an fall. Is the Haltech FLEXIBLE enough to allow fuel mapping for such extreme changes ?

Also, on the Haltech site, it did say that that eh e6X is capable of 4 different fuel, and timing maps, and can switcjh between 2 fuel maps, and 4 timing maps, on the fly. Would that be applicable in answering my question? seeing that the Haltech reads intake temps.

The Haltechs work so good, that when well tuned they work perfect at any temperature altitude or load.

In South America, where we sell most of our kits and Haltechs, we set up the cars where you can be at sea level and 95 degrees and drive up hill to the mountains for a couple of hours and be at 8500 feet above sea level and 40 degrees and still keep a good A/F mixture thru the whole rpm range regarless of boost.
The key is the air temp sensor and map sensor which compensate for a good performance.

When running closed loop, it is even better.

I am looking at the Haltech E6X right now, but I only have one problem: the interface. Not only do I have a lot of programming experience, but I am an artist and interface designer by trade. I would love to create a more user-friendly Windows version of the the Haltech interface for myself if I get one. Has anyone attemped this yet? I know it's a long shot, but I could create a beautiful and user-friendly interface for the setup if I could get a discounted price on it. I would just need the I/O specs information, or ideally, drivers.

It would make it a lot faster and easier to tune with, and I could make it so that you can overlay the maps for comparison and see the timing, boost, and fuel maps simultaneously. You could also graphically draw/manipulate the points with a mouse. You would still be able to manually enter data, too.

Let me know what you guys think.
 
I'am mesmorized by all the info. I really want to change my tranny or car, to get more out of my kit. My car must be a one of, since I am running around 11 psi max, hitting the throttle hard and making globs of power, no detonation, egr within limits. I am so happy with my kit, is the only thing I wouldn't get rid off or maybe I could if I get a E6X (laugh)

Go all the way baby!! I would buy that interface from you! And I am sure everyone else who has an E6X would do the same.
 
I do not believe haltech will release the source code. The main interface for the E series and F series is Serial and DOS serial at that. No one has been able to succesfully use a USB to serial converter and run the program from within windows XP.

The E-11 has windows based software, but when it comes down to tuning, it really isn't about looks, its about getting the car to run well. The haltech is one of the easier systems to tune because you are dealing with bar graphs, you simply raise or lower the graph until your fueling or timing is correct... however you can also enter a numerical table with cells as well.

Your best bet would be to contact haltech, but people have tried this in the past as well. Go to www.haltech.com and click on downloads, then download the E-11 software and see if thats more what you're looking for. The E-11 retails for around $1600 and packs way more than any FS motor would ever need.
 
best thread evar

it sounds like that on a MSP, since to run more than 9psi you need 440's and EMS, you're better off getting forged internals and upgrading to a T28 too. that would be a beast.
 
Yes in order to run over 9psi on 91 octane you would need to upgrade the injectors ( when using a tuned Haltech )

The 440's will allow you to run up to 15psi on the stock T25. However I would not run over 10psi with the 440's on 91 octane. With 100 octane I would run above 10psi.

If you are going to spend the money on forged internals, might as well go with a Big T3 or the hi-boost IHI ;)

exactly.

yea, but my friend's sr20 T28 will need a good rebuild and new owner by the time I can afford all that jazz. which is never...

i'm just trying to learn as much as i can before i throw down on a MSP this summer *crosses fingers & saves more money*
 
ok i just bought eric burmiesters rally engine and i need a stand alone to tune it so i dont blow it up

how much is the haltech with all the parts i need...

how would you say haltech is better than microtech?

would you say this is a good ecu for high compression applications...

my engine will have 11.5:1 compression... and all the goodies

can you switch maps for 100 oct to 94 oct ?

so i CAN use the stock maps and modify them?

would you say haltech's programs are easy to tune?

thank you

The E6X with 1-Bar MAP sensor and connectors runs $1350 shipped.

Cheaper, easier to tune, does just as much with half the hassle. Heres a quote from a well known tuner from Australia who deals with both systems daily.

OK, the real world difference.

MT has 16 load point vs E6X having 32
MT injection time resolution is 0.06ms vs Haltech at 0.008ms. This is a bigger and bigger issue the larger you go with injector, or the smaller the motor is.
MT has 3D fuel maps (they call it Matrix Mode), but 2D ignition rpm with 2D MAP correction. Not true 3D. Haltech is true 3D
MT has a pretty handset so it is quick to make changes. Haltech is laptop only.
MT is locked for your ignition type, meaning you cant eg. switch from a Nissan to a Mazda. Haltech is user configurable.
MT you cant save and load maps.
MT is cheaper.
MT has a few things Haltech doesnt (but should), like MAP based throttle pumps, and throttle pump ignition advance.
MT comes with 20psi MAP sensor on board. Costs extra to go 30psi.
MT only calibrates closed throttle, not full range.
MT comes pre-configured so the car will start and run as soon as you wire it.
MT staged injection has rpm and load selection
MT does not fully do idle control, boost control, or closed loop. It does basic forms, but not very well at all.
Lots more little stuff.

Draw your own conclusions. For me, the ignition mapping and injection time resolution is the biggest issue. Try something like 850cc injectors on a 2L 4-cyl, and with MT you can pick between 10:1 and 16:1 for mixtures. Do it on a Haltech/Motec/Autronic and you can pick the mixture you want, and get it repeatedly. I had a 20B the other day with 6x1600cc injectors with an LTX12 trying to run it. I had the same issue at idle, 10.3:1 and fouling the plugs, or 15:1 and stalling from too lean. I have done 12A's with even old E6A Haltechs that have idled smooth on 1600 injectors at my selected mixture. I had to instruct the owner to run a smaller set of primary injectors. I am not saying MT is bad, it just has limitations that some applications will be fine with, and others will show up as bad with. I have had an LTX8 on a stock standard 13BT pass full EPA emissions tests here, but I have had a race prepped 13B ported, T04, custom intake, big injectors, etc... pass the same test much much easier with an E6K.

For me, the extra small amount of money is worth spending on a Haltech, but if you are on a total budget an MT can get you going reasonably well. They are not the bee's knee's, but they are probably the best of the busget systems IMHO. Just because Racer Joe uses MT does not make it any better a system than it really is.... something the kids on the forums are blinded by.

would you say this is a good ecu for high compression applications...

It's good for all compression motors, as long as the motor is good, the tuning is the same. Haltech's run all kinds of motors including high compression.

my engine will have 11.5:1 compression... and all the goodies

I'm sure it'll be capable of making plenty of power, but it may or may not be the best street motor.

can you switch maps for 100 oct to 94 oct ?

Yes the E6X has a dual map switch you can setup for use with a dash switch.

so i CAN use the stock maps and modify them?
You will not be using the stock ecu fuel or timing maps after you install the E6X.

would you say haltech's programs are easy to tune?

Out of the other programs I've used, the interface is rather simple to learn and undertand as compared to those. Visual learners work best with the haltech software.

I was clearing out some of my old files and found something the N/A guys might have wanted to see. This dyno sheet compares my 1.8L N/A BP motor running only a 3" exhaust with the stock ecu and with the haltech e6k.

my plans are now to go with the microtech... i can get everything i need for under a grand...

and one of my friends does know how to tune... so he is going to help me out..

all my stuff will be in by the end of december...

im so friggn excited
 
Sounds good, I'm still not a fan of having to replace alternators and the such. Good luck with your endeavor.
 
Yes, go read up on Spool's system using the microtech. Theres like a $500 core charge because you have to replace your alternator.
 
but what spoolin is doing is removing the stock ecu and having the microtech control everything...

you do not have to do that with microtech... the microtech can be used the same way the haltech is used...

i sat in a 3rd gen rx7 with microtech in it that had all the creature comforts...and was using the stock ecu...

i plan on keeping the stock ecu to control all those parameters. eg. ac , alternator, lights, odo, tach....

i see the microtech as being a better choice for what i plan on doing...
 
So why would Spool even want to go that route when he could offer it as a parrallel system? What's the point of it?
 
to be honest i have no clue... maybe he is just trying it to see if it works..

imho i think that its a waste of his time trying to do it.. bc there is no way he could do it better than mazda could.. there isnt much to improve on.. other than fuel and ignition timing...
