Hi all,
Trying to diagnose an issue I'm having with my S52 OBD2 swapped late model e30:
Thoughts? I plan on getting the car tuned as I've got a 3.5" HFM and piping I want to run to match the 540i TB and also want to account for the cams. Do you think my setup is just different enough that it's the tune making it act weird, or does it sound more like a VANOS issue?
Trying to diagnose an issue I'm having with my S52 OBD2 swapped late model e30:
- Fresh build 0 mile S52
- M50 IM
- 540i 3.5" TB
- light weight flywheel
- 24lb injectors
- Riot Racing cams
- Hacken TT canned tune (whatever that means)
- Freshly rebuilt VANOS with Beisan seals
- Low on power below 3k rpm, big power surge above
- Mostly steady idle but runs a bit rough
- Progressive ticking between 1k-3k rpm
