Does this come with the latest version of the Haltech?

Tunermax, SC? jeez your car is going to be a beast

Also, I noticed on the Haltech site that it says MT only. Can someone confirm that this will work with AT?

2 more questions - need answered quickly

Does this completely replace factory ECU? Do I remove the factory ECU and put this in its place?

I have been having intermittent problems with limp mode, with no CEL. It happens when I drive my car hard for more than 10 minutes. I havent really been able to figure out exactly what causes it. It will go away if left for a few minutes

I have every breather mod you could mention - all the pipes going into the cylinders and all coming out, and my exhaust smells like a go kart after driving hard. Is it possible that a tune would fix this smell, and maybe get rid of my limp mode problems? I am baffled by the fact that I am not getting a CEL. So I feel like the problem might be one the designers of the car did not anticipate, such as people putting non OEM exhaust etc.

5/16" Spacer, Fast Intentions HFCs, Borla TD Exhaust w/ magnaflow X-pipe, Top Speed headers, Stillen CAI, 3.7 FD, VLSD.

I think thats everything as far as power is concerned.

No, this is a piggy back. The stock ECU stays where it is, this hooks up 'in-line' with it.

As for your smell, I'm working on a way to get rid of it, it's becuase you took the cats off primarily.

but there's been some speculation that the primary cause for the smell is the stock Crank-case recirculation. Thusly a Catch can setup might take care of the smell,

Bump for some actual interest.


The HR guys sure have it a lot worse when it comes to PNP Haltech systems....

is the HR ECU/harness different again?

Yes the HR uses a special harness, and its a lot higher then this setup

I am actually looking for one of these! I am replacing my Uprev program and looking for the str8 plug and play Haltech.
Please PM me some pricing. I am located in vancouver/Calgary and need shipping to Blaine WA

If your car is a 03 Coupe then you do not need this special version of this system. (going by your sig) edit reading more into it you said your using osiris right now, so this def is not the system you need. The ECU this is for Osiris does NOT work with. Thats the whole point of this special system.


This is for 03 Sedans with Auto trans only. And not a lot of them even are this grey plug.

yup. Early 2003 sedans only - build dates between 02/02 and 11/02 i believe

anyone ever get one of these? might pick one up to tune my car for NA one last time before I go FI, any chance of free shipping to 92057?

so you can still tune from the MAF w/this right, or do you need MAP?

quite a few maximas are running these,

you can use maf , map, tps for load source, tune with VE, Injection time, and Lambda corr.


most haltech tuned will tune with map and in VE.
