Hey does anyone know if the haltech engine managment program come already default or do you have to hook it up to a computer and input it in? Well i got everything hook up don't have a laptop yet and was wondering if it is wise to turn on the engine or do i have to install the program and adjust my bars to get the car going?

 

The haltech has a base map, but it wont do you any good, unless who you bought if from loaded a base map for YOUR particular car. Otherwise, i recommend going on ebay, getting a decent laptop with a serial port and doing the tuning. Or! leave it to the pros to tune your car.

Where are you located, we might be able to work something out, i will be in the states in october.

 

agree...i would let a pro do the tuning. A small mistake can cost you an engine. Or download a map from someone with the same mod and start from there.

 

Don't assume there IS a base map installed for your application, unless the previous owner (if used) guarantees there is one.

Straight from the Haltech manual...
Please disconnect all coils and fuel injectors before turning the Haltech ECU on - this prevents damage to those components when changing configuration in the settings for your application.

Oh yeah! let me tell you more about this Haltech i have. It's a OLD dinosaurs F9a engine management system. "DONT ASK ME WHY I EVEN HAVE IT" . Well anywase this Haltech takes a RS232 serial port and only older laptop's got them. But now all the new laptop got the new serial ports that look more like a monitor port or USB port. So different serial ports. I was wondering if i was to change the Haltech serial link extension cable into a USB serial port and plug into the new laptop would it be alrite? Would the computer be able to read the haltech?

 

No dude, just get an older laptop and download the software of the haltech site if you dont have it. If you want to use a new laptop it will have to have Windows 2000 or older, cause XP dont work with DOS. The other option is to use a USB to Serial adapter, but there are problems with that too. So, ebay your self a P3 or older laptop with serial port and Win2000 or less. Preferably Win98 or Me.

And also, the other strange looking serial port on newer laptops is an external monitor port, not a serial port.

 

Also wondering if any one would tell me if my wiring connection is correct......by GREY (Switched 12v) and BROWN (Trigger) in the Haltech manual instruction. This is for the F9 or F9a Haltech engine management. So i ran Haltech Grey wire to the TAN wire and the Haltech Brown wire to the PINK wire on the leading Coil?

 

thanks Claudio RX-7.... for the computer help!!!!

 

The grey wire is for 12V switched, to turn on the haltech you have a heave read and heave black wires that go directly to the battery, and an additional black that goes to chassis ground. The Brown wire goes to the tacho out on the trailing ignition module, or the negative side of your leading coil. I missed what setup you got.

F9, F9A, F9-8 and F9A-8 are basically the same ECU, the difference is how many injectors they control, and they have or dont the additional features. The F9 and F9-8 only control 4 or 8 injectors, and dont have the additional features found on the secondary connector available, how ever, the O2 sensor input does work and its through the secondary connector. Haltech can change the firmware on your ECU to turn it into an F9A if you need it.

 

Ok On the F9A setup i got my FLYING LEADS "BLACK (ground), Red (supply 12V), Grey (switched 12V), Orange (TWO Orange wire - 12V and fuel pump), Brown (Trigger), and Blue (Aux Input). I'm still pretty new at this sooo let me how i did.

I ran the the (BLack) wire to the Battery Neg........
(RED) wire to the Battery Positive......
(Grey) wire to the Positive Leading coil...... I think!!!!!
(Orange) one wire to the fuel pump and the other to Batter Positive......
(Brown) wire to the Negative Leading coil..... I think!!!!
(Blue) Unused

Oh yeah the BROWN (Trigger) wire did metion about tachometer output some where in the dashboard don't know where exact. So i hook it up to the negative Leading Coil. Let me know if i did it correct.

 

NO! QUICK! DISCONNECT THAT GRAY from the possitive lead coil. Even though that is a switched 12V, its not recommended for powering up the ECU.

One of the orange wires goes also to 12v switched, the other to the possitive lead of the fuel pump, and the negative lead of the fuel pump goes to ground.

Finally the Brown wire is exclusively for the haltech to be triggered. So you need an RPM source, the negative post on the leading coil is where you hook this up IF you are using an old distributor, if you use an MSD, connect it to the RPM output on the MSD.

Now, inside the Haltech there is a dip switch pannel, that needs to be configured depending on the installation you have.

 

Can you Help me out! when it comes with wire i'm a begginnerrrrrr!!!!!! wondering if you can tell me what wires go what and where? Sometimes when it talks about triggered i get lost trying to find where and what it is. Any pictures would help a lot!!!!!

 

Ive already mentioned what wires go where, but here:

- Thick RED to Battery pos.
- Thick Black to Battery neg.
- Second Thick Black to chassis ground (not battery)
- Brown wire to an RPM sourse, either the negative terminal of your leading coil, or the tach output of your CDI box, since you havent indicated what kind of ignition system you are using i cant tell.
- Grey/Red wire is the 12V activation switch wire for the ECU, it goes to a 12V switched sourse (ie. something that comes on when the switch is opened to the ON possition, not the ACC).
- Orange wire goes to either the same switched 12V you used for the fuel pump, or a separate one that also comes on when the switched is in the ON possition.
- Other Orange wire (usually one of the orange wires has a grey stripe) goes to the fuel pump's possitive lead terminal, this way the haltech has control of the pump.
- The negative terminal on the fuel pump goes directly to ground.

The rest of your wires are for sensors, fuel injectors and other things. Is that clear enough for ya?

 

what should i do if i only got one Black wire .... to the chassis ground or battery neg? Oh yeah i'm just running a stock turbo II motor no modifaction... should i put the old FB distributor and install msd ignition (but what kind of msd ignition?). With the Grey/Red wire let me know where is the best spot. Can you tell or show me?
