Now that there's a solid handful of supercharged LAP Goblins, I'd like to start a thread for their specific tuning. I'm having an issue right now and would like to see how others have handled it.
My donor was a 2009 G5. Has an M62 supercharger with 2.9 pulley, dual pass and 42lb injectors.
I originally took my car to a tuner, and it ran okay, but was in PE all the time on the highway (XFE tall ratios.) Also had vac leaks and I was running on the factory MAP. It was running a MAF only tune.
Fast forward. I'm running an LSJ TMAP and have done MAF and VE tuning a few different times. It runs and drives pretty well, but skews lean in boost when MAF and VE are on. If I'm running MAF only or VE only, no lean condition; runs great.
I had to build/re-zone the VVE table by hand after swapping to the TMAP because the factory table ended at 105KPA. I suspect there's something wrong with a coefficient or calculation somewhere, but I can't find it. My tune and a quick log are attached. This is a work in progress, so feel free to critique.
Other supercharged LAP guys and gals, feel free to post tunes/logs if you feel appropriate. At this point, mine is completely my own. Everything in there, I learned on Goat Rope Garage for free and I'd share my learnings in a heartbeat.
