Microtech vs Haltech, help me choose.

[becauseican]

I am trying to decide which standalone to go with for my 1jz. I can get both for a good price. My friend is very experienced with Microtech, he worked at Mazsport in Australia for the last year and a half installing these units......3hours installed in a stock FC RX7 from pulling it in the shop to installed and running on the MT ECU. He also runs a Haltech E6X in his AE86. I am leaning towards the MT unit, LT10 with the X6 ignition box. I know the LT12 has sequential injection, but after like 4000 rpms, its a moot point as things are happening so fast anyways. Do any of you have experience with these units?, and what do you think about them?. Which is more user friendly?

Post your opinoins.

Sequential injection is a nice feature WHEN things are happening really fast. :)

It means that the injectors are opening and closing once -- for twice as long -- rather than opening and closing twice for half as long. It has the practical effect of stretching out the operating range of the injector.

Haltech E6 is really outdated. If you're considering Haltech, go with E11v2, not less.
Idk about microtech, but wired, installed and tuned Haltech E8 myself a year ago.

The only annoying issue with E8 was jerking at light load due to ugly stock 7M CPS design (it has too much freeplay). Later I tried different sensor and that problem went away.

As for software, it's not very user friendly and top notch, but can be used for sure. Tuning manual is VERY user friendly and will guide you from installing Haltech till tuning. Native datalog viewer is complete POS, so I've made my own (If you'll go Haltech - pm me, and I'll send my datalog viewer).

PS: now I'm dealing with AEM... what can I say, it has its own issues and bugs, so now I'm thinking that most system has bugs so the only question will you be able to live with them =)

I think if I go Haltech I will use the E8 or E11. I am starting to lean that way as it has closed loop 02, and a few other good options. Does the E8 and E11 have target A/F option?.

I reasearched those units and the Haltech E11v2 is the way to go. It is feature rich compared to the Microtech, and you don't need to send the unit back to get upraded. You can use the map sensor or an outside map sensor with out having to send the unit back to the factory. The LT12 vs the e11v2 cost more when you add all the things that will make it fly.

That all depends on how you pair them up. You can fire three pairs of two injectors and still fire them once per cycle.

I'm biased (I'm a Haltech dealer), but the E8 and E11v2 are solid performers for their price range. I personally think the E8 is a steal, and will work flawlessly for you if you don't need full sequential/direct fire control for your 1JZ. If you do, or you may want to in the future, the E11v2 is the way to go.

For peak power, it doesn't really matter which EMS you choose. For drive-ability, I like the Haltech units, the idle control and closed-loop boost control are the best I've used to date. The latest Haltech firmware release (as of July 28) now has a target AFR map for autotune.

There is also a plug-in wiring board available (through my website) to let you plug right in to your 1JZ wire harness.

nope sorry.

Per Engine Cycle = 2 engine revolutions. ;)


Per RPM perhaps but gains you absolutely nothing.

Haltech E11 Randy, do not go cheap now.

Jeremy

p.s. Not that eather is a bad option but I think the Haltec offers some more fetures and is somthing you can grow with.

I'm going to have to disagree with you here Joe ;)

OEM applications that I've seen, use sequential until around 3000rpm, and then they go back to batch fire, due to fluid inertia.

Remember, you only have a very narrow window in which to inject the fuel (only 1 of 4 cycles ;)) - by injecting half the fuel needed ahead of time, the fuel is already in suspension when the intake valve opens :)

Haltech E11 Randy, do not go cheap now.

True dat....they got new auto mapping feature, and a few people in ny running hard with them.

Anthony

regardless of how much they hype "autotune" (From the New ProEFI to the everything inbetween). Do not rely on it!

It is meant to be used to get the final portion of the tuning done but not the major parts.

I watched some one try and use the Auto tune on there Aultronic and it cost them an engine. Do not rely on it at all, its great feature for the last bit of tuning if any. You still needs good tuner to get it set up and running safly.

So I just ordered the E11v2 for my car, I hope to have it installed within a week or two. I will also be installing an E8 on a customers car (2jz swap) I will post my results, and BIC should be coming out with a P&P setup for the 1jz's. If anyone has any maps to share feel free to post them here.

i am think teh hall tec root but aem is still in the back of my mind thou

that or map ecu 2 if the timing works on it

After all the problem I have seen an herd with AEM the past few years If I was doing my car again it would be on Haltech or Motec.

Jeremy

[NashMan]

yae there is alot of mixed up minds about aem

i used em befor and have yet to have an issues
i like it cause it is plug and play halteck far as i know of does not make plug and play

i have yet to cheak thou

Haltech isn't plug and play but I think the Company that Makes the AEM makes a harness for the 1JZ/ and 2JZ. You must wire the car other wise Ryan. Go full standalone and for go any piggy backs. I got my Wolfv500 with dash display for 1735.00 delivered. That is cheaper than HPF is selling the AEM for. I also got a new wire harness with the unit.

Now going Haltech or anything other than the AEM gives you the flexibility to do what ever you want. I went with Corvette LS2 coils. This eliminated the need for finding an igniter, because those coils have the ignitre built in.;):naughty:

[Turbo Drifter]

One other thing Ryan is rememeber our harnesses are getting old and dry. We have been getting Randys Haltech wired in this week. Its so nice to see new soft wires that you are not scared to touch.

I have had may harnesses appart and all of them have had degraded wires. Even the harness out of the 95 Supra harness I used for my 2jz AEM swap had lots of old dry and broken wires.

After all the problems I have had with harnesses and AEM I should have gone Autronic or Haltech.........still may. :nono:

Jeremy

[NashMan]

oh i forgot to mention i have a brand new harness thus why i looking for pnp all sell it thou if i do go with halltec and get my money back

but for now i have maftpro and i might use it or use some thign els kinda still up in the air the only unit i have really never toyed wiht was the micro teck stuff witch i don't plan to run any way

but tell me how it goes randy with hall tec it's good uint

If your car isn't there give haltech a call in USA ask for claudio an he will have one made for you....
He has a 1jz MA70 PnP as we speak so give him a call for more info....
PM me for phone number..

[Turbo Drifter]

Just a update for you guys, Randys 1jz Supra running a Haltech E11v2 ran on the first try. The only problem was Haltechs pin out of the 1jz/2jz igniter is wrong, Bill was able to find it and fix it right away. Its amazing how simple it was for Bill to set the peramiters and then start it. Lots of detail was put into the harness and the time and effort was worth it it looks amazing.

I think we are heading to the dyno tonight or tomorrow. :naughty:

Jeremy

[becauseican]

Yes we went for the first road drive last night, there is a few things we have to work out but it drives very nice, I hope to get it onto the dyno tomorrow or friday.....just in time for the drive to SILV.

Randy

[tbcmorris]

Any updates randy?

I ask beacause I am doing research now to determine if I wanna go aem or haltech. You have to make your own harness for haltech?

Also I'd rather bump an old thread for an answer than start a new one!

Well I got it installed and tuned and had about a week to drive it before driving 1800 miles to Vegas, I made it all the way down and back, and i also Dyned (423 whp at 17 psi) and raced. Not to bad for only a weeks driving on a new EMS. The Haltech ran great, I even taught my wife to tune!!!, she was logging pulls and adjusting my A/F's on the hwy, it was great!!.

We did make a harness from scratch, the long harness haltech had enough lenght to build it. I wanted to make sure all the wires and connections were perfect, and with a 20 year old stock harness there is no garantees, I didnt want to risk potential problems. We also just installed an E8 into a 1jz car, and patched it into the stock harness...we had it running in about 4-5 hours.

For the price you get a great system, you basicly get all the options that the AEM has minus a few features like knock control, for a better price and with a much easier to use software. Haltech now has thier new Platinum Sport ECU's to replace the E8 And E11, I will be putting one in my car and running it this spring/ summer, and best of all they just plug into the older E8 or E11 harness plugs!

Claudio is working on a P&P harness for the 1jz, they do have a 2jz mk4 P&P but the plugs are way different than the mk3 1jz.

BTW, BIC Performance is now an Official Haltech dealer, so shoot me a PM or Email if you need anything.
