Interesting.
(1) Isuzu have categorically stated in writing that the addition of the aftermarket SB-Chip is the root cause of the issue at hand due to altering the OEM ECU mapping, leading to over fueling and subsequent piston melting.
(2) Their stated justification for this assertion is (a) observations (b) pictures and (c) SB-Chip manufacturer self disclosed tech specs of the subject chip.
(3) At face value it looks like a done deal, however, this is not necessarily so.
(a) Isuzu have conveniently non disclosed the data from the ECU log which may or may not substantiate their stated claims.
(b) The mention of the SB-Chip altering OEM anti pollution settings is another red herring issue altogether and can only be considered once any ECU log data is produced.
(c) Isuzu have not stated that they have eliminated all other possible scenarios that may have caused the subject damage.
As stated by Isuzu you now have to wait for the Govt Agency/s to get their act into gear so to speak.
Just as an aside. I have had a JEEP Cherokee 05 CRD since new and added a Chip after approx 30,000Kms. Increased the performance exponentially, however, caused top and bottom turbo/I-cooler hoses to split and send the ECU into limp mode.
When adding that 'plug & play' chip a competitor (Ex mechanic wk
shop owner) I know quite
well in the 4x4 winch competition fraternity, advised me not to do so as it would result in blown turbo hoses and other issues. Doh! Doh!
After the JEEP went into limp mode (cylinder misfires) with my wife driving one day, there was serious, robust dialogue between her and myself that resulted in the subject Chip being removed for ever more. There has never been another issue with engine or anything else for that matter.
Just in case your wondering - No! I'll never 'Chip' another vehicle. Learnt my lesson and seem to have got away with it.
