I have the Main VE table dialed in (THANK YOU Joecar!!) and am now working on first cold start-up issues.
Engine is a 383ci L31 Vortec with Mercruiser MPFI, 36# injectors, XFI280 camshaft, P&P heads, long-tube headers, and ported TB. I have tried logging the initial spark when cranking so I can find my problem, but no luck. (Log and tune below)
**Yes, the log shows 66* F on start-up, but earlier in the day I was seeing 32* (or 0* C). I have noticed if i use DVT controls, if I command 10* advance, the engines fires off perfectly. I believe i have removed all adders that would effect this, but the values don't seem to match up to what I have in table B5909.
What should I be logging to find these adders to B5909? Any tips to help the cold start problem? (Seems like it is excessively rich with too much timing)
