Title: HELP 24V VR6 swap Golf MK2
Post by: JTDPerf on July 07, 2021, 08:27:00 AM
Hey!
I own an MK2 Golf and I swapped the original engine with VR6 24v code AYL from VW Sharan. So far the car runs but acts weird.
With the VSS unplugged rev limit is around 5000 RPM and car drives fine and with VSS plugged revs to 7200 but with an infernal rev hang between gears and stutter only in 4th gear at any rpm. I can't understand why stutters only in 4th gear (feels like intermittent fuel cut) because ECU down't know what gear is selected.
I scanned the ecu and i have 5 DTC's in the picture attached.
I performed SAI delete and don't have ABS on my Golf. I read on other forums if ECU doesn't communicate with other canbus partners throws some problems.
I don't know what to do next, I even asked a friend to scan my ecu and give me the bin file hoping you can help me..

heres your file with sai removed and vss error rev lim removed. youll still get a cel for the error as i did not remove that.

Can you post again the bin file because for some reason it doesn’t appear here anymore. Thank you in advance!
