I came across tuning the 1GFE engine on standa alone ECU. The engine has forged internals, there's G25-660 turbocharger on long runner 6-1 exhaust manifold. 730cc injectors, and aftermarket FPR with fuel return line to the tank.
There's something unusuall happening during the fuel calibrating. The engine is happy to see high VE Values such as 100-105% in the negative pressure zones like 3-4k rpm (short ratio gearbox makes those values as highway cruise RPM) 60-100kpa maintainnig desired lambda of ~1 in area up to 80 KPa and 0,9 around the transition zones ~100KPa. Under boost (1-1,5 bar of possitive pressure) it tends to lower the VE values to arrounds of 90-95%and it chase the target well aiming for 0,76 lambda.
Is there anything to be woried about? Where to chase the problem solution?
