The below
PIWIS
report shows unexplained misfires. These misfires occurred hours after a failed state inspection by the dealer. Dealer tech is confident the
DME
flash is the culprit.
DME
mfg. has admitted others having the same problem. I have no tolerance for these types of malfunctions.
This is not beta-testing!
DME
mfg is working on the problem but I have lost confidence in the product. If I lose confidence in something, that something goes away, by either a refund-return or the trash-man.
Perfectly good reason to switch to the
softronic
race plenum without losing money on the flash. :banana:
I notice you had a number of ignitions (over-revs) in range 2 & 3 (and 1 in 4) - did your
DME
flash also raise your rev limit cut-off?
It certainly was supposed to. But without knowing what the limits are to begin with I have no idea when these over revs happened.
It certainly was supposed to. But without knowing what the limits are to begin with I have no idea when these over revs happened.
Which begs me to question what the rpm's were when the over revs happened? Is this info shown on the FIWIS Vehicle Analysis Log?
Unfortunately, they record data by engine hours, rather than mileage or date, so for example: your Range 4 over-rev occurred at engine hour 246.3, and your most recent Range 1 occurred at 265.7 hrs. If you know what the current engine hours is (I didn't see it on the print out) then you might get a rough idea of when they occurred.
Range 1 over-revs are not uncommon if you hit the rev limiter or redline under normal circumstances. I don't think you should be hitting the higher rev ranges unless the
DME
re-flash is allowing it, or you missed a downshift.
Yeah without knowing when the car was flashed vs. when the overrevs occurred it is impossible to say if the flash had anything to do with it. It could be a missed downshift at some point as was already pointed out. I have seen unmodified cars have misfires as well too, sometimes cause by faulty coil, bad fuel, etc. While this information can potentially be showing problems with a flash, I don't think it is conclusive by any means. Having a full report before and after would have been more telling.
I meant to say "I have no idea at what RPM's the over-revs happened". If the flash raises your red-line doesn't the flash also raise your over-rev limits?
All over-revs were post DME Flash. But I have to admit the over-revs was operator error, at least the stage one. It does rev up quick in first gear! Stage two was and hopefully the only mis-swift, stage three and four were just flat out trying to stay ahead of a very fast cobra, mission accomplished.
I wouldn't think so.
What do you mean by "failed state inspection"? Smog check?

Mark,
I am getting 3rd hand information, possibly 4th hand info, all from the dealer, so in your defense I apologize for placing absolute blame on FVD.
