csnow said:"Millions of dollars in developement" that still rolled out of production with a lean spot on the OBD1 ECUs between 4,000-4,500 rpm (USDM 2J). Just using this as an example that even Toyota doesnt get the code done right all the time. The base tune is thrown out the window when it is modified with the Mines. I see this as merely a flashed eprom piggyback that is manipulating the timing and fuel curve. What if your injectors are not flowing to Mines calculation? Are you gonna have to run a piggyback to make corrections? With a standalone, you are in control of all variables in real time for your setup.
+1 on that example of OBD1 lean spot. You're so right. So much for Toyota's millions of dollars in development huh? A stock ECU is best, for a stock car... Once you start modding, you have to add piggy backs and other electronics to supplement or fool the stock ECU to make the car run as efficiently as possible(BCC, FCD, AFC, VPC, etc etc). You can't even boost over 1 bar without modifying the stock ECU in some way. Even then, I'd be willing to bet a properly tuned standalone could extract more peak power, power under the curve, AND MPG than any stock ECU could and cost around the same price range.
It'll be a frosty day in hell before I take my car down for 4 weeks to get a reflash stock ECU or pay 1800 for one.
And just for the record, I have a Mine's ECU(it didn't cost 1800 either) in my car, so it's not like I'm saying it's worthless. It's great for what it is. But to think it's better or more effective than a standalone would be silly.
