Hi,
My aps tt kit is installed succesfully but we have encountered some problems with the Utec software. I cant insert my injector size and I dont have any "options" to click on like in the manual. The only thing that comes up the screen is: " For future applications only". It isnt on the cd that came with the computer.
Help!

Thx

 

The basic injector scaling feature is not in the 2.8 ver. of software any closed loop fuel changes will need to be applied to the 0 percent column and the 10 to 100 columns are injector pulsewidth.

Thanks,

Its the 2.8d version of the Utec. The duty cycle needs to correspond with the size of the injectors.

 

In the parameters of the UTEC There is first line: open loop fuelling
Second line: Injector flow
third line: Stock injector flow.

Line 2 and 3 says for future use. How to solve this? What did go wrong?

 

You can´t use this 2 lines , you only need to make the corrections in the fuel map , if you are using a 550 cc injectors you need a -15 in the 0% column......

 

just leave the two lines both with 380 and 380 in them, you scale the injectors by changing the 0% column on the fuel map.


550s will be somewhere around -15 % on the 0% column

not a utec problem though

 

We are using the stock aps injectors. They are 500cc at 4 bar fuel pressure.
