Hey guys someone wanna tell me the advantages of doing this? what sort of gains can you get and how much money do you need to spend?

also what actually is involved in doing it, some specifics would be nice hehe :)

Matty :)

well, if you want to JUST do your A/F ratios, you can get either a A) Apexi AFC (something) II or a Greddy,

if you wanna do Ignition timing and really advanced stuff,

HALTECH :badgrin: :badgrin:
gains to be had, depending on what mods, but you can surely increas your hp by up to 40%

take me for a exampe ;)

Well i Drive for a living im an onsite tech so i dont wanna compromise drivability, more power for minimal dollars would be what im after ive already got a k&N panel and a redback muffler

I guess im just looking at whats next. what is gonna make me the most power for the least amount of cash?

Matty

(thanks for your input booya :))

yo matt
u saw my car after the unichip and how much it kicked ass!!! Driveability wasnt lost at all. For a next mod id say for u to go a set of extractors. Then go the unichip later on :D

Haltech in general takes over all the aspects of the car,

If you are looking for drivability and the occasional grunt, use the Apexi SAFCii where you can set your A/F ratio for drivability and economy as well as performance as a press of a button, mind you, it's not cheap but it's user defined and programmed unlike Haltech which you will lose all the OBD, fuel economy problems, cold/warm cranking. I'm not saying it will happen but generally, that's what Haltech is prone to. Haltech is better off in a mild/high modified car.


CHEERS

The alternative to consider is the greddy e-manage which can give you full adjuistablitly over fuel and ignition curves like a haltech, but retain your stock driveability and can be altered on teh road with a laptop computer.

Think of it as a Unichip but one that you can alter yourself or any dy no of your choosing.

We use it on our TT Magna and its awesome.

We also sell it for a good price and can provide wiring harnesses diagrames on how to wire it up.

dave - does this still retain the functions of the trip computer / avg fuel usage etc?
if no,
does the unichip?
cos i wanna upgrade my computer eventually but i refuse to upgrade it at the expense of the trip computer..
Ben.

Dave, what about Motec systems, are they similar to Emanage ones or standalone like Haltechs?

I was reading on their site and it seems they're like the Emanage.

Do you have any comparisons on the emanage to the motecs? I think the one for our cars would be the M48 (correct me if Im wrong)

Thanks Dave!

i think motec do piggy back and they are also renowned for their stand alone systems like the haltech. they are expensive...when i got quoted for my gemini

and booya.....the greddy does ignition timing too me thinks

I can't comment on piggy back MOtec don't klnow about them but the normal motec is like a Haltech.

The greddy will not disrupt the trip computer or the fuel economy readigns etc - the only time you hav a problem ther is like with my car where I have larger injectors and the readings are no longer accurate.

I've got a unichip in my car. The unichip doesnt affect the trip computer at all.

Unichips have to be taken back to the place that sold you the unit for re-tuning and so fourth. Sounds almost like a case for the unfair trading mob.

At least the SAFC/GREDDY unit can be tuned by anyone with a descent amount of expereince - not to mention every time you perform a modification to your car you won't be spending $$$ on a re-tune.

Nah you dont have to go back to where u got the unichip to retune it. Im pretty sure you could tune the unichip urself if you got the software. It was pretty simplistic when i watched the guys tweaking it on my car.

Seriously - you have to. I've got it in a previous issue of Hot4s or something that says you have to bring it back all the time.

Nah you dont. It doesnt make a difference. The only reason they say that is because you would have someone working on your car thats already had experience on it.

There are actually alot of people in Victoria who can tune the unichip.. just that they don't advertise their services...

Where ever you go... DO not go to ART and tune your chip....

As for tuning the unichip yourself Gami, I'd rather u not do it :p It's not as easy as u think 8)

E Manage on the other hand... easier to tune though...

I'm getting Autronics for the Evo!!!!!!!!!!! :D

To clarify you cannot tune the unichip yourself as you cannot purchase the software without a unichip licence hence you can't do it yourself.

You can only get it done at registered Unichip agents.

As opposed to the greddy whih we can buy the software and do it yourself or a dyno of your choosing.

yeah that makes sense... Unichip is kinda dodgy in that respect, but atleast he has a piggy back computer whihc deos the job he needs...

BTW guys, in Victoria at least, ALL these chips, computers and interceptors do not comply with EPA regulations. This means that if the cops inspect you and give you an EPA notice (or you get one in the mail) and the EPA person sees the device and isn't feeling friendly, you have to either take it off or pay a few grand for an emissions test.

So you might want to be careful about how obvious you make your mods around the police. And if you piss people off they can report you to the EPA and you'll get called in.
