What parts do I need to replace the unichip with the UTEC system?

 

Start with the search button.

 

Not actually that much info on people that have done the change using the TT kit (im assuming thats what you've got??)

So a bit of help wouldnt go amiss. Im looking to do the same very shortly.

utec, 3 bar map sensor, map selector(if you wanna run different fuel and ignition maps, and turboxs boost solenoid(optional).

 

Does that solenoid definitely work ok? cant see it on the website.

 

You will need to purchase the following:

UTEC
Pressor Sensor
Some kind of boost controller, or a boost control solenoid.

You will need to remove the following:

Unichip, and all wiring...including the APS solenoid.
You will also need to reconnect your factory crank angle wire. Some people will opt to leave the shielded APS wire in place, and rewire it the factory ECU harness.

If you need UTEC's, let me know!

 

I bought the UTEC and the MAP sensor.

I cut my Unichip crank angle wire about 6" from the Unichip. I cut my OEM crank wire about 8" from the stock ECU. I spliced the two together, to maintain the shielded cable (although I'm still not sure I believe there is a problem with the non shielded wire).

Thats about it. I didn't change out my solenoid, but I haven't gotten it to work yet. I think I can make it work, I just need some time.

 

the solenoid i'm referring to is from the dtec system that turboxs uses on the srt-4. that's why it's not listed on their website. my car is currently getting tuned, so i'll call the shop in a couple of days to see whether or not it works.

 

I would also recommend purchasing the tuner so that you are able to have the A/F ratio monitored with the utec. This also allows you to road tune.

 

If you already have a wideband then don't get the tunerpack. 3rd party software allows you to log AEM, among other, widebands with the UTEC data.

Oh, and thats another 'must have', 3rd party software that makes the UTEC look like it was created this century.
