ECU tuning

So, has anyone try to chip tune the ACE ecu?

I will try it in a short time, at SKN. The figures are +15hp and +10NM.

Including the other mods i have made (60mm exhaust, tubular manifold, throttle body) i think it will be great.

Maybe not what chiptuning tuning the engine after such modifications will get a power increase to any appreciable level, but I think first you should comply have any sharper camshafts and adjustable circle.

friend,you need more than 15hp for move well your S8´s

did you it finally?? results??

hey!

well not yet, i just finished the exhaust and intake, i have begun to collect parts for the head overhaul, will buy schrick cams too, and the last thing will be the remap.

and how many power could you wait with that mods?? 160hp??

well i belive at least 170, if not more...

no, i will not swap the engine with a 2.2T, it is not gonna happen

B.T.W where is compi's ecu module ? I look under the passenger carpet - no luck. ?

behind the airbox.

remove the passenger side trim below the glovebox, and reach with your hand behind the airbox. pull it down.

Ok, i found it. What is the voltae between 23 pin of ecu and earth in your car in idle ? This pin is VAF potentiometer 2nd pin. mine at idle shows 1,46V, but Autodata says that it must be 0,4-0,75 at idle. Tried adjust potentiometer with screw near connector, but it ranges from 1,40V till to 1,60. What next ? Change potentiometer ?

I found the way, soldered potentiometer and, now i can adjust in ranges 0..5V

where is this potentiometer?

Originally it is located under the black silicon shield near the jack of VAF potentiometer, but soldered one, sho looks like tihs:

instead of old one (10Kohms) and now can change resistance in ranges 0..10Kohms, and so change the voltage to the ecu in ranges from 0..5V

http://www.obd365.com/wholesale/v54-fgtech-galletto-4-master-bdm-tricore-obd-function.html with the latest version V54 properly can do that. Works no problem for cars, trucks, motorcycles, Marine, BDM MPCxx, BDM Boot Mode Tricore and checksum.

hi, skull all is okey with programm SKN?
