I've yet to do a 2.5l 5 cylinder build. If I recall it's one of the best flowing VW heads ever. Gasoline dreams, ALH broke ish reality.
It would be nice to see big TDI power. As in like 600-1000whp stock head and block perhaps porting internals and airflow fuel mods.
I suppose if you go sky is the limit and fab heads etc. This is my first foray into diesel after age 10-40 wrenching and growing up in a household and family who were gen 1 haltech users and tuners when turbocharging was less reliable even to OEM.
Bought a MKVI JSW solid top 6spd TDI and loved...
I don't think you will be able to squeeze 1000hp out of a 2.0l common rail 06A block even if it's been filled solid. Factor it down by 1/3rd of a Cummins (6.0l or so iirc) It may do a few pulls but that's it.
I don't think a common rail can do the head flow required to get air in, and the...
New ECU with same tune provided less Flux in IQ and timing at idle and under load.
As usual more than one issue. Next is running new QA wire and MPDS wiring possibly N108 wiring as well to ensure it's as good as it can get.
Runs great with an IQ OF 2.2-2.6 at idle and even less control...
Scan. Codes. This is a symptom that comes with my p1651 Quantity Adjuster control deviation*
If you lift off throttle after it happens once the rpm drops below 2000 it's back and working again.
Heat does make it worse.
You leave my Monster (TM) Injection pump harness magic gold plated oxygen free cables alone you big meanie. You'll see when I gain .2hp and .001 seconds in the 1/4 for a ripping 16 second pass.
No srsly tho. 4 real. What I have dug up from forum members here analyzing MPDS & QA signalling via...
I think there is one but I am looking to run entirely new wiring from the ECU to the injection pump in parallel. For now there will be some solder action and ghetto fix.
Bosch says gold plated only for the injection pump harness. Given what wiring issues can cause here I want to do...
