You changed directions a lot.There is obviously a lot of info and dialogue missing here.Do you have links to other threads on other sites you exercised along the way about the ins and outs ?I've got some questions too .... Question #1 -- open to all comers in the know.You said your dial gauge adapter wouldn't fit the TDI pump head.Can a faktry stock AHU TDI (98 Jetta) Inj Pump be fine tuned/timed with a dial indicator - just needing a different adapter than what we use on IDI ?As in - set/verify Injection Timing mechanically - versus VagCom.(and any specs on thread size needed for TDI hole)
Yes the AHU pump CAN be tuned in the exact fashion as we do on our IDI.. But I see no reason to, as the computer can change all the timing values at any given time by itself. All the parts are there for the gauge to physically follow the plunger in its movement. However upon thinking about it, it almost seems to me that the AHU pumps may be set initially by dial gauge.. and then fine tuned with VagCom, else why would they have the ability to put a gauge in the end of them right?
the rover pump resolves 1-2k pumps for tdi-m... 2-300ish.. almost direct fit and such..
