How To Set VW ALH TDI Pump Timing Using Autel Scanner

[@julian8615]

Hello! I have a 1.9 tdi agr 90 hp stock, the IQ is 2.8 / 3.0 with a temperature of 92 ° at idle and with everything off, are these values ​​correct? If I increase the IQ more (close to 3.6 / 3.8 ) I will to achieve better performance? thank you so much

I know around 2.8 is where you want to be for the most optimal setting, the higher the number the less fuel is sprayed, so if you are looking for more power you should lower the number and run higher boost. But obviously do that at your own risk and too much fuel will cause you to fail smog due to too much smoke out of the tail pipe

Also the higher the number the less torque you make, horsepower isn't affected much when you raise the number

@@Cepyy916 thank you very much for your valuable information! 👏

Finally I adjusted the IQ to 3.2/3.0 MG at 92° and although it lost little in performance it gained more smoothness at idle and even sounds a little better

@@julian8615 That's good news! It should also increase mpg slightly

Would the autel mk 808 scanner work also ? I see yours is the maxi pro mp808 , the mk is cheaper and wouldn’t likely use it much but it’s what I found

[@Cepyy916]

You'll probably be ok with getting the cheaper mp808, the only difference between the 2 is the pro has the hot functions menu but the mk808 doesn't.
