Does that mean I'm ready for this; If so, where do I enroll to get schooled on the VE tables and the rest of the fingers that make the hand work, or is it just seat of the pants trial and error to see what fingers get broken and which ones still bend ?

Not quite advanced class, but definitely INTERMEDIATE level. ... See attached 1227747 TBI ECM screen shots to get an idea of what to look for when tuning (your 16147060 PCM will be similar). BLM's are fuel corrections, used to determine if the engine is running lean / rich. BLM's below 128 are Rich and BLM above 128 are lean. Usually BLM's between 123 ~ 133 are acceptable. ... Adjustments to the Fuel Table (VE table) adding or subtracting fuel is what is changed to correct the BLM to an ideal 128. ... Check out the '7060 information in this gearhead-efi tread, http://www.gearhead-efi.com/Fuel-Inj...Information-85 and follow the links in that tread for more information. ... I use Excel spreadsheets to tune with because the data from a data log is very large and Excel is good tool to manage HUGE amounts of data. Open Office (freeware) is another tool available to manage HUGE amounts of data https://www.openoffice.org/ ... dave w
