Ok i am interested in getting a haltech. I was wondering if any of you who have them could tell me how they are hooked up? I am not buying a stock ECU so does that work still? How does this system hook up to your car........ Does it replace the existing wiring harness? how does the module hook up to the existing connections? Is it easy to tune or do you have to know what you are doing and be some sort of computer wiz?
I have been reading the other posts on the forum and have more questions. For the flying lead loom, would i be better of getting that or the terminated one? What about the MAF? do i need that still or can toss that? I also want to simplify my engine bay too. so i will need some help with what will stay and what will go?

Yes it totally replaces your factory system ,computer and engine loom only ( this is what stand alone means ! ) ,However I do not understand what you mean by " not a stock ECU " , anyway , you use the supplied equipment which interfaces with the factory equipment ,ie injectors , ignition pick -up and trigger etc. If you do not have access to a dyno tuning can be a bit tricky and tedious at times , just start rich and then lean out and you should be safe , the software is desinged to be user friendly , basically you just modulate some bar graphs up and down .Get the terminated harness !!! (terminated means that it is already fitted with all the various jacks and connectors ) ,you would be able to just plug everything together, and no.., no MAF only a MAP.

Thanks for the info. one more question. well 2. what is a MAP sensor and what is a Bar sensor and where does it go?

Marcel Burkett

MAP stands for manifold absolute pressure , it is a pressure sensor used to sense and convert the physical pressure produced by a turbo ,vacuum etc.. into an eletrical signal which can be interprited by the ECU , it should be mounted on a vibration free ridgid structure like the " fire wall " ( located between you and the engine compartbent ) or apron (shock mount) area and also within approximately 13inches , if mounted too far sensing and response of the sensor are slowed down. A BAR sensor on th other hand is something new to me ,I can only guess that it is also a pressure sensor (BAR is a unit of pressre measurement 1 BAR = 14.7psi).

i think he said he wanted to clean up his engine bay a little. that is not going to clean it up.

is anything lost by using the k2rd harness? i mean, can you have the haltech tunned to full capacity with it. all i ever hear is that it is a 5 min install.
