Re: MR2 Intemitted Stalling
THe stock fuel map is/was apparently on the rich side of ideal, for safety sake. How it varies with capacitor ageing, I don't know. Overboosting - I think that's a wastegate issue, probably an actuator issue, not the ECU.
Mine is running silly rich and I am expecting the fuel pressure to be high, due to the regulator being old. If it is, I will buy an adjustable reg. Also my stock actuator was leaking so I have bought a Kinugawa actuator with 11psi spring, and blocked off the TVSV system, until I see what's happening. Then off to the dyno for adjustment.
Stock recapped ecu, stock injectors (I think), Hope that helps.
