I didn't say it won't work, it just won't be able to read the 5s block correctly. If you want to use the frankenstien swap to its potential it'll be a better idea to get a standalone ECU versus the 3sge ECU. You can probably just use a piggyback to help manage the air/fuel. That should work just fine. But a standalone will be more affective in showing the potential of a 5sge.
ok ... what sensor/sensors are there on the block, that the stock 3sge/3sgte ecu cannot read???
To my knowledge the only reason why you cannot run the a 5s-fe ecu with the 3s-ge/3s-gte head is because of the ignition system and the maf is different... If someone wants to save money and want to do this frankenstien motor your talking about under a budget... They can run the stock 3sge/3sgte ecu... All they would have to do is re-wire the harness...
The 3sge/3sgte ecu will work fine with this setup ... And the only sensor that would be on the block off the top of my head is the oil level sensor ... Which are found on the American 3sgte motors and not on the JDM motors...
A standalone is going to make that much power over the stock ecu especially if the motor is internally stock... I.E. stock piston, cams, ports, and everything else... Why spend a couple thousand of dollars to have the whole car re-wired and on the standalone unit to gain a smoother idle and 5 to 10 horses...
But then again I could be wrong... Maybe your right...
I dont know ... I just like it when people on this forum give advise to new people, when they have no experience on the subject...
