Hey guys.

I know both chips have proved very good for magna owners. Im trying to find out if anyone has used the Haltech or Unichip on a AWD TL. It has a custom exhaust, CAI, BM Headers and a K&N pod air filter. It will also have Whiteline Swaybars and a Whiteline Strut brace at the time of chip install after which i will be looking at the brakes.

The main things I want to know are:

Is the E11V2 Haltech worth the extra buck?

Does the Unichip give sequential injection?

Has anyone else had trouble deciding and what was the determining factors for you?

Also are the Fuel Pressure Regulators worth it and what Brands would you recommend to work with a Haltech/Unichip piggyback.

Spent the money on another mod where you could achieve better gains, id recommend speaking to some of the NA guys pushing good fiqures because a chip is going to do is advance your timing and lean it out

I will be putting my old unichip back on after i get my extractors finally. I had it off my TE. The haltech will offer more options like multiple maps and possibly more inputs but its more expensive. EGO has one and has only had good things to say. The unichip will do the job but it all comes down to the tuner in the end. Either if badly tuned will not deliver the desired results. If you are going to do further modifcations and possibly turbo/supercharge you car then the Haltech will be a better option. I would like to see wat you get at the wheels?

Do you mean like Stage 2 cams and such?

Ego has a Haltech Interceptor, a piggy-back, which is Haltech's competitor to the unichip. The E11v2 is their top of the line full replacement ECU. It's a freaking good ECU but way overkill for what you have.

The Unichip is a piggy-back ECU, and all it will do is modify the factory ECU's injector duty by a percentage and delay or promote the signal from the crank angle sensor by some number of degrees. It doesn't give you precise control over either.

Also, the Unichip can only be tuned by authorised dealers, which may or may not be a problem for you depending on where you live.

its pretty unfair trying to compare a full stand alone ecu and just a piggy back

ive got the haltec in mine, had drama's at first but its goin sweet now..

as for fuel reg i got a malpassi in mine but they all do the same job its just a fuel reg

You got the E6X tho.. not E11v2. The E11v2 costs about twice what the E6X does. :shock:

yer, pretty much the same thing though. the e11v2 was kinda overkill for wat i wanted and needed

Yeah I was talking to Dallas about the E11v2 earlier today.. it's got some nice stuff in it.. better closed loop behaviour than the E6X apparently.. can drive more igniters and stuff like that.

Do you know if the guys that did yours set it up for closed loop or not?

dunno wat they did to it haha as long as its working :D

possible as much as a dislike RPW speaking to them might be a option but before hand id talk to cthulhu in regards to his modifaction progression in terms of powers and gains and whats best for your buck

or check out some of the members profiles

If you comparing the piggybacks that ok..

I Got The Haltech and its great..made the car drive like a differabt car.. The Haltech has a lot more settings.. i couldnt believe what it does.. i thought it was simple like the unichip..

The costs are a little higher for the Haltech and it works a treat.. From what ive been told the major differance is that the unichip runs ur ECU and then can chucks a wobbly and over take and cause drama and need a retune.. where the Haltech works with the ECU and doesnt try to take it over..

if you got the extra few dollars get the Haltech.. if not get the unichip..:D

They both work very similarly though..

They both intercept a load signal either from a TPS, a MAP or a MAF sensor, modify it up or down by some amount, then send it to the ECU to trick it into believing it's got a different load than what it does (and therefore make it inject more or less fuel). They also both intercept and modify the signal from the crank angle sensor to advance or retard ignition timing.

These are the things the I know the Interceptor can do but I'm not sure if the Unichip also does.. The Interceptor can:

- act as a boost controller
- modify fuel and ignition maps based on intake air temperature
- control an extra injector (think NOS)
- control auxilliary devices like shift lights, water sprays, etc.

These are the things the I know the Interceptor can do but I'm not sure if the Unichip also does.. The Interceptor can:

- act as a boost controller

The Unichip requires an additional module (small matchbox size box that connects to the Unichip) to give it boost controller functionality.

Has anyone gotten the e11 and found out how good the sequential injection is?

For that matter, has anyone used the G-Reddy or other brand of piggyback/chip/ecu? What's the feedback on these? What brands are other cars using?

Having used all of the above unichip, greddy, emanage, haltech and checked out some competitors I woudl say that the haltech is a better option over the unichip.

The emanage still in my opinion if the vehicle is using forced induction the best piggy back system due to being the only one that works on 1 input being maf sensor, and on injector and ignition outputs which means it can handle larger injectors iwth no problems.

All other piggy backs haltech, unichip, exede etc all have issues ifyou go larger than 20% on your injectors becuase they only work on the input side of the factory ecu and cannot pull enough fuel out to lean out at idle or cruise.

For n/a cars we pretty much go with the haltech now - in perth we do them fitted and tuned same price as we used to do greddy units. Give the customer the choice now of either unit.

There is no comparison between an E6X, E8 or E11 compared to a piggy back. My magna is going E11 but I want full sequential ignition (Going to six individual coils) and injection which the E11 can run. FOr the the majority of people the E6X is more than adequate running semi sequential injection and either semi sequential ignition via three duel coils ro stock distirbutor setup.

Unichip I beleive honestly, has lost its market to the newer and better systems as well as its antiquated system of dealer tuning only. With a haltech or greddy, you can go to any tuner and have them do your car.

And yes the Haltech interceptor has functions to control NOS etc.

Yes this is correct as Scott from haltech has it on his car and im still waiting for my free setup..:P
