engine management system?
 
Posted this question in the haltech forum as well. I was looking at the haltech f10 as a possible candidate for my 12at. But was wondering which engine management you guys used for your 12at projects. And if someone has used this haltech unit before, would I need a boost controller as well or would this engine management system do both? I'd also like to know which management systems you guys have used and would recommend?

F10 is a fuel only computer.
I really don't consider it to be an "engine management system", as it's only fuel.
A true EMS should control fuel and ignition timing.

If you're looking at just fuel-only, you're asking the wrong questions.
You're looking to control fuel delivery of a fuel injection system - nothing more, nothing less.
Distributors are so archaic technology compared to modern ignition timing control via mag sensors and toothed trigger wheels.
When you figure out how to properly control ignition timing, come back and and ask us for more info...

okay I'm just looking for the best system that will control many aspects of my new 12at. I'm regularly a carb guy but when I finished the 12at I put the EFI harness on it and need some computer system that I can install on my car and start it up. I don't want to go back to a carb but I'm unsure of what I need to make this engine run. I know you guys know which system would be the best for my 12at project and I was just wondering which one it is. I said the haltech f10 because from what I've read you can basically hook it up and start the car...but it wouldn't be the first time I was wrong about my assumptions...

that was a little bit on the harsh side, don't you think?

if this is your first ems, maybe a microtech would be a little bit better choice. just tell them it's for an fc when you order it. fc parts are abundantly available, cheap, and relatively reliable. microtechs are a snap to tune also.

Sure.
That was my point.

why would you just be rude like that? you do that in a lot of your posts.
we all know you know what you're doing, but just leave it alone if it's not gonna help.

Lee Lyons Mar 11, 2005 02:39 PM

thanks for the help guys I've been looking around and doing alittle homework and found the haltech E6X...if I do get it I'm going to get it with the flying lead kit, E6X connector kit, map sensor for up to 15psi boost, single ignition coil, and boost/ fuel/ ignition trim module...what do you guys think...anything I'm missing

GUITARJUNKIE28 Mar 11, 2005 03:19 PM

do a search on the e6x. myself and a lot of other guys have had trigger/ignition problems with them.

if you get one, i'd suggest using the stock CAS wiring and splicing them into the e6x right at the ecu plug. the new wire haltech is using for the CAS is garbage.

Cause some of this stuff is getting repetitive.
A LOT of the questions can be answered by doing a decent search.
Most people asking questions like this do not bother with a search.

I can punch in "Haltech F10" into any web search and get the answers pretty quickly.
Did the original poster try that first?

Society is getting too damn lazy...

this is true, but why does it bother you that much?

eViLRotor Mar 12, 2005 11:17 AM

Anyway, on the topic of E6X ignition issues. I went ahead and bought one anyway, since the one we installed on my friend's car works perfect. We ran the CAS harness separate from the rest.

Also, I will be covering the CAS harness with this EMI/RFI adhesive supression shield :

The 12AT is pretty rare nowadays, so I don't know if you will find too many people with 12AT experience. This link may help. Note that the F9 was replaced by the F10, so the article is a bit dated.

So when you go to the Haltech website, and click on the Downloads menu, and open the F10X Manual pdf file to page 79, what does it tell you? :D

Add one more wrong assumption to the list. :)

A fuel computer or EMS needs to be tuned by a professional for good results. Anybody can certainly try to blindly find their way through tuning, but damage to the engine is a greater possibility during an educational tuning process, so keep that in mind. A good rule of thumb is to not attempt any part of the EMS installation or tuning if you don't understand that portion of the manual.

GUITARJUNKIE28 Mar 12, 2005 07:25 PM

evil. good idea with the wrap, but i think the stock wiring is sooooooooo much better that it would be worth it to tap in right by where the original computer plugged in.

but more power to you if you can make it work easily... it took me forever to get rid of the rpm spike/rfi, or whatever that was on the few i did last year.

Yup I finally got rid of mine as well! I agree it was a PITA! but in the end my car is fairly drivable, now if only I could handle the Cold Driving problems... :(
If you get the E6X or before you do do a thorough search, microtech may suit you better is easier to install and comes with a descent base map. The haltech is a little tougher in each one of those feilds.

GUITARJUNKIE28 Mar 12, 2005 09:50 PM

grab yourself some turbo2 coils, crank sensor, and air temp sensor and tell the microtech it's an fc. it's getting tuned anyway, so what does the computer care?

hell, even i'm switching over to microtech lately.

Lee Lyons Mar 12, 2005 10:30 PM

alright thanks all so much this has been unbelievablly helpful...and I have done searches but just found myself more confused so thanks...the engines got a brand new distributor and wires...will the t2 coils help with the microtech system or is it just a recommended upgrade...and would I want to buy a crank and air temp sensor out of a t2 of would I buy it as a microtech option...as per telling microtech its an fc...what exactly will that accomplish other than giving you a basic map to work with?

GUITARJUNKIE28 Mar 12, 2005 10:37 PM

it's the whole setup of the microtech...
you can take a haltech off a car and load a new map and use it on another totally different car...microtechs have to be configured.

just post a wanted ad in the 2nd gen section for the sensors. you'll pull your distributor out and plug in the 2nd gen crank angle sensor, then use the t2 coils instead of your current one.

i'd be happy to come and install it all for you, but i'm in california...too far away.

what you might want to do before you decide on anything for sure is go to your local tuning shops and find out what they can do. if they install it, you might want to think about a system that they're more familiar with to make things go smoother.

Lee Lyons Mar 13, 2005 01:24 PM

I guess that would be the most major problem that I face...is the lack of tuner shops that are around here...I'd say that other than mazda dealerships we have no tuner shops in this area which I find quite odd as a fairly big city of just over 200, 000 but there just hasn't been a market for it so I guess any shops that their were couldn't stay in buisness...so I'm kinda on my own...I really don't want to have to cart my car to another province to have it installed and tuned...now if it were stereo components I could name more than a dozen places that do custom fibreglass sub enclosures and do interior work...but the tuner shops went out of buisness just before it got really big within the last couple of years which is a shame...but if you want you could come on a road trip in your 7 and tune my car...lol...I have a feeling I'll be on this or the microtech forum quite a-lot!!

GUITARJUNKIE28 Mar 13, 2005 01:40 PM

i love helping, but that would cost me thousands to drive up there!!!

jreynish Mar 13, 2005 02:01 PM

leelyons where are you located in Canada? There may be someone arround... I may know of.. what province or city are you located?

Lee Lyons Mar 13, 2005 09:43 PM

Located in Saint John...New Brunswick...don't live in town but am only like 10 minutes away...lol...ya it would probably cost quite a pretty penny to drive way up here...I was just joking though...although I wouldn't stop you if you had a thousand dollars you wanted to spend driving up...you located in south california or south carolina?

GUITARJUNKIE28 Mar 13, 2005 11:07 PM

california.
i need a vacation in the worst way possible, so if you wanna fly me up there, i'll install it for you :)

jreynish Mar 14, 2005 12:40 AM

well I am sorry I cannot help you out either I live in SK. I thought if you live in the west I would be able to take a road trip and help you out.... but NB is a little to far away for me... sorry dude.
But like guitarjunkie28 said, you want to pay to fly me up there... I would be happy to install it for you ;)

Lee Lyons Mar 14, 2005 01:18 PM

I think that tunning it to actually make the engine run insync would be the major problem.

GUITARJUNKIE28 Mar 14, 2005 01:30 PM

naw...that's the easy part

making sure you get all the correct parts is the hard part.
