Hi guys.
New to the RB26 scene.
Bought the car last month and plan o. restoring it bit by bit ...
Engine Mods on the car:
- Motec M84
- walbro 525 pump
- Aeromotive fuel regulator
- ARC intake box
- Intercooler
- HKS intercooler pipes
- Titanuim down pipes and catback.
- Greddy spark plugs
issue, cat had RPM hesitation before and when i got it i did a full replacement for old oils and consumables and installed the motec and tuned it on 0.6bar ... cat drove fine for couple if days then started missing
took back again to the tuner, he said it shows that there isnt enough fuel, so i installed the pump, regulator and returned .. got good gains.. car drove very nice when i took it from the tuner, next day the car stated missing again and RPM wouldn't go and car will start backfiring at 4-5k RPM .
No maffs any more as motec uses Map sesnor.
any ideas ??
