Location: Stockholm, Sweden
I'm planning to implement Genboard V3.3 on my Volvo 745 '90.
Current specification:
- The engine is a rebuilt standard B230FT (Original engine).
- 2319 cc, 96.3 mm bore, 80 mm stroke.
- Forged pistons (Venolia)
- Forged H beam con rods (SPM)
- "O-ring" sealings between cylinder head and engine block
- Oil cooled pistons
- was not standard until 1993 on B230FT...
- Larger "gourp A" oil gasket with internal hatches
- Uprated oil pump
- 531 cylinder head
- almost same as the standard cylinder head head but with "better" intake side that allows better air flow.
- "Larger" turbo, Schnitzer. Don't remember the specs for it.
Plans:
- Use original harness as much as possible
- Use original sensors
- Extend the harness to acommodate directfire, cam angle sensor, wide band lambda, etc.
Questions:
- The original crank sensor is a 60-2 hole VR sensor arrangement. I guess that the original LH 2.4 ECU doesn't have the filtering circuit on board but some external filtering circuit which generates a TTL "home" signal for every revolution of the crank shaft. I need to find this and decide wether to omit this totally and use the VR sensor option of GenBoard or use it and configure the Genboard apropriately.
- The cam angle sensor could be implemented by obtaining an older distributor for the LH 2.2 (or maybe motronic) from an older 740 which used a hall sensor with 4 signals to control the ignition. By modifying the distributor, this could be changed to give the apropriate cam "home" signal.
TODO:
- Find out what is needed in terms of components
- Buy a Genboard
- Make a buylist
