Ok guys, a few weeks back I fitted a 7 ecu into a 6.
Copied over his ecutek maps, into a tephra 90550001 v5.10 rom as he wanted launch control, and wanted to see what all the fuss was about with pops and bangs.
Anyway everything worked well (once I replaced his BOV).
A couple of weeks later he said he liked the pops and bangs, but asked if I could remove them, as he was a little worried about his turbo popping, when he does the sprints.
So he came round, and I reset the ALS settings to the stock settings.
Removed the low load neg timing, and flashed it back to the car.
Starts car up, and it won't rev up past 4500rpm :eek:
So I check the rom, and can't see anything wrong with it.
Flash back in the rom that came off, and it works 100% as normal.
Flash back the edited version (no pops and bangs) and won't rev up again :confused1:
So flashed to an 8 rom (to blank ecu) and flash back to the no pops and bangs rom, still won't rev up :angry:
So I flashed to a stock 90550001 rom, and it was fine.
So I then made up a complete new rom, copying all his maps and settings over from his orignal 6 ecutek rom, into a fresh untouched 90550001 v5.10 rom, and flashed that in, still wouldn't rev up past 4500rpm :angry::angry:
In the end I went through the rom, and changed every cell in the timing table 1 by 1 until I found the cell causing the issue.
Turned out to be the cell in the 10 colum, at 6000rpm.
If it was set any higher than -1° the car wouldn't rev up over 4500rpm.
So has anyone come across this problem before ?
And any idea's how to fix it ?
