    185 ECU in 215

    I sent an ecu to someone to tune my OG 215 ecu for bigger injectors and such. He ended up getting an empty box in the mail. To make matters worse I purchased an ECU locally being told it was out of a 215, but its actually out of a 2003 185 SC. I paid a lot more than I wanted for it too.

    Searching through threads I see people running 185 ecu's in a 155 by adding the MAP sensor. But I don't see anything about flashing a 185 ECU to a 215. Anyone have the answer for that? Are these wired differently or is it just software? Or am I out a thousand bucks in ECUs?

    Thanks guys

    They have same injectors but different fuel pressure so fuel maps dont work good in 215 and it use different boost levels. Sure 100% that minimum you need put 215 software

    Thanks for your reply. I been reading a lot today. I also learned that there’s some incompatibly between 04-07 wiring/engines with sensors.

    Just get a stock 255-non-IBR/260-IBR ECU, build from there, if your 215 is a 2008 above, but 185 and 215 are internal differences thats why a lot of 155,185 and 215 can and cannot work together just depends on parts, i would not use an ECU from 185 on a 215 because the boost (SC) and fuel levels are lower from different Piston and RPM, if they can tune 185 like a 215.
