Hello and good day. Today i just done converting F20B DOCH PCB-004 obd2b stock ecu to obd1 P30-003. Convert 3 wire IACV to 2 wire IACV with adapter plate. Bypass VTP A4-D6 with jumper wire and disable in crome. No check light, and steady idle now.

Using H22a basemap - engine crank but cannot start the engine.
Using B18c basemap - engine can start and have steady idle.

Do a datalogging on idle only, AFR is lean about 17.70 reading. So i do adjust fuel map until i get idle around 15.xx.

Question is, can i used b18c timing to run and tune f20b engine? Need suggestion or any basemap that safe to start tuning the f20b engine.
