I noticed when I went to put in my injector latency values, that the voltages in ECU flash are incorrect, but they are correct in romraider. In ECU flash I have values between 8 and 16, which matches the data for the 2.5l, in romraider I have 6.5-16.5 which matches the manufacturer data from Deatschwerks for the 03 2.0l wrx, which is what I have. Is this normal? Or does this mean me ECU flash definitions or rommetdata is wrong? Even after editing the table in romraider it has different voltages when I open it in ECU flash. So far this is the only table I've found to be different.

I can help send me the rom file.

Thank you Al. Sorry for the late reply I have been out of town. I've attached the bin file. Let me know if there's anything else you need!

They're still different. I can edit it the right way in RR, but when I open it in ECU flash, the values are different. Here's both tables in both programs

You will always use ecuflash to write to the vehicle. Looking at the 1st picture it looks like its trying based of a 32bit ecu 2nd picture is scaled right with a 16bit ecu On my laptop its reading 6.5 volt up to 16.5 volts. First picture is what you sent from ecuflash. Second picture is from the romraider. And 3rd picture injector data scaled against a std rom file and what im seeing in my ecuflash compared to a stock rom file from a 2003 wrx

6.5 volts - 2.67

9.0 volts - 1.78

11.5 volts - 1.11

14.0 volts - 0.66

16.5 volts - 0.43

Ok, so your ecu flash shows the incorrect values when you open my bin, but it's ok? What you posted is correct for my car and that's what I have in rr and ecuflash. Do you think I have incorrect definitions for ecu flash? Or am I just totally not understanding what you explained to me? Lol Thank you for all you help I really do appreciate it! I haven't had any other issues like this before. Everything else has been right.

this file is set of a 2.5

Ok, I finally figured out I could change the table values by editing the map definition in ECU flash. Now I have the correct stuff in both RR and ECU flash. Thank you so much for all of your help!
