såpass dyrt ja... noen som veit åssen jeg måler ladetrykk da?

1. Start Motor

 

2. Move the MFA selector to "2"

 

3. Press and hold the MFA end button (keep holding)

 

4. Stop motor

 

5. Start Motor

 

6. Release the MFA end button.

 

7. Press the MFA End button one time.

 

 

You should now see 84-104 readings fluctuating with idle. Anything higher than 104 is not right (vacuum leak). Much less than 84 is probably too much timing advance.

 

Go run your car!!! 3rd and 4th gear to REDLINE. Carefully note the highest #'s you've got.

 

A pullied charger should not make less than 11.6psi, and even so, thats weak. A Stock charger should make ~~11psi in perfect shape!

 

USA EURO Hg(#'s of boost/vacuum) Comments

15 200 -23.7

55 400 -17.8

90 600 -11.9

127 800 -5.9

148 1000 0 (Atmosphere- ala no boost, charger is bypassed)

172 1200 2.9 psi (Your charger is dead or big boost leak)

192 1400 5.8 psi (Your charger is about dead or big boost leak)

211 1600 8.7 psi (Your charger needs new apex strips or big boost leak)

228 1800 11.6 psi (Great for stock pulley, Probably needs new apex strips if 68mm pulley)

242 2000 14.5 psi (Great for 68mm pulley on stock charger)

255 2200 17.4 psi (Great for 68mm pulley on heavily ported charger, hold on to your ass fast!!)

 

255 and up folks need to be careful with fueling, as the programming maps end at about 242 on the ecu Dynotuning, and air/fuel/egt gauge, and custom chip recommended
