2004 eec v

[mbray01]

I have my suspicions about what Im dealing with, but looking for some second thoughts. have a roush blower on an otherwise stock 4.6. FBFG2TF CALIBRATION.

2 biggest issues are 30+% fuel trims that i cannot clear, tried clearing kam with multiple different devices, trims are still there, trying to tune around it, doesnt work, because its never the same, may be 30% one pull, 41 the next, 34 the follow and so on. also tuning around it changes load drastically.

second issue is ecm does not follow timing schedule Put 5+* in entire borderline, and 10* in mbt, make a pull and it is still climbing to 22*, total. cant wrap my head around why cam wont clear, and why ecm is not following timing tables

Could you post your tune?

So, the long and short of it is, somewhere in the reading/writing process, the file became corrupt, and although everything appeared correct, it took someone elses eyes, (decipha) to spot that it was in fact corrupt. Tried flashing a known good file, still no good. Even tried another ecm, issue is likely on vehicle side, either electrical issue or noise on the comm bus. I have done hundreds of these and this is the first to give me issues. So anyone stumbling across this in the future, i had to correct this with a quartehorse and a chip.

hpt and eec-v aren't the best. most have had issues. Normally have to use an older device with earlier software to read/write and another to log. Not sure if they are even worrying about eec-v ecu anmore at this point honestly.

Can you post your def/xdf or whatever? I have what seems like possibly the same ECU that I'm trying to work with and I just cannot find a definition for how to save my life for this thing. If you're editing it with HP tuners I'd really like to know how you're doing that
