1991 Audi 100 (2.3L/5cyl 2 valve NF engine.) originally with KE Jetronic (weird, many older engines had proper fuel injections; this might be the last KE-Jetronic engine built)
- fuel rail fabricated
- will be kept NA (normally aspirated). 139 Hp ? Smooth and clean running and fuel economy is main target (not power)
- factory compression ? Around 9.6 ?
- KE jetronic => replaced with VEMS (speed density setup, 115 kPa MAP sensor)
- owner planned to "alien-log" the factory ignition advance table. However, there is almost certainly no value in that table. Should not be big deal to make a better igntune (for RON95 fuel). Probably the orig is tuned for pessimistic lower RON fuel
- ditributer kept for now
- either 35pin factory connector kept, and VEMS made with frontplate for that connector '''NOT feasible, because one connector is for ign, other for fuel, better cut off...'
- => wires cut and EC36 + EC18 connector crimped the way to go
If tuned in August, might need some tune adjustment in the winter.
Sensors
- MAT ?
- WBO2 will be added
- knock ? Does the block have provision for 2 bolts ?
A/C
compressor is in, but was not operated for some time. Needs gas, most likely (or was it washed and changed to R134A ? dunno)
Trigger
- primtrig: 5 window HALL (on camshaft, in distributer)
- sectrig: HALL (not used for now)
