So i got my ECU today in the mail with the new APR chip on it...i put it in the car and drove it and...nothing...still boosting 7-9 psi...It says something about the cruise control but it mine the cruise control is not working....what can i do?....Also thinking about deleting the cat...is it worth it?

 

From APR's website:

How EMCS Works

Step 1
Press and hold the "set" button on your cruise control. After approximately five seconds, the "check engine" light on your dash will begin to blink once per second. This will tell you that you are activating program one. This blinking sequence will continue for approximately five seconds.

After this five second interval, the "check engine" light will begin blinking twice per second. This will indicate that you have activated the second program. This process is continued to access any remaining programs you may have purchased. (three blinks = program three, four blinks = program four).

Step 2
Once you have activated the desired program, simply release the "set" button. The "check engine" light will stop flashing. Turn the ignition key off for 10 seconds, turn the key back on, and you will be locked in that program until you change it again.

It's that simple.



Sounds to me like if this is the setup you bought & your cruise control stalk isn't working, you're probably still in stock tune. You might have to fix your cruise control in order to select another tune.

 

Ok.. So i did this...i held the set button and the CEL blinked once...turned off for 20 sec and drove it and.....nothing...still the same

 

My APR is a single-program unit so I'm not entirely sure, but from what I'm reading with APR's guide is that you activated program 1, which may be stock tune. Try holding it for longer and "selecting" program 2 and see what happens, then program 3, then 4. I would have guessed they would have given you some documentation as to which programs they put on your chip.

 

Mine is single-program too.....what should i do?

 

Give them a call. They should be able to give you the best answer.

 

Oh, my bad - I was under the impression you had the multi-program one. Like evelluser said, I'd give them a ring and let them know what's going on, they should be able to help you out.

 

APR has great customer service, call them walk them they will walk you threw!
