A Chip Tune will bring the CRD to real life.
When programming thru the obd2 port, the processor counts up the number of programming attempts and susscessful attempts. This is saved in the ecu so the dealer can see it's been tuned. The dealer network has access to this data and can see the multiple tuning attemts and void warrenty for altering the ecu.
Normally when programming thru the obd2 port you can only access about 256kb of the full 2meg flash. Guess where the emissions maps are located - not in the 256k maps!
The ECU, ABS, and Instrument Cluster all keep a record of odometry so that correct mileage must match each other. If another cloned ecu is installed the odometry will not match and the dealer can void the warrenty.
In other words people having someone chip your vehicle they had better know what they are doing and have the work arounds. As of lately with vehicles being hooked up to STARnet the engineers/techs at other end will be able to see these alterations unless the programmer hacks the system and erase their tracks. What brings this home is a gasser that was at the dealer this past week that was connected to STARnet and before tech could get the ball rolling for the repair problem STAR voided the warranty and refused futher descussion on the vehicle. The out come was big $$$$ to the owner of the truck.
This is sort of scary. Would it void my 3/36 and my 7/70? Or just the 3/36? Is InMotion able to cover their tracks on this one?
You would have to ask InMotion about that, I would check on other diesel forums like Fred's TDIclub Forum for example.
I know a lot of people do the chipping, and not just diesels. My LX forum forum has a lot of people having their LX car chipped, but these cars have been very reliable without a lot of trouble codes and few have been on STARnet. When the tech is just using local STARscan tool the techs could ignore or even possiblely miss the mod. It is a heck of a risk to take when you own a vehicle that just one Fuel Injector list for $950+ and if you think that is big bucks you don't want to have to pay for a fuel pump.
About KERMA. I have used his injectors in my TDI and they were an excellent product that a tech would not have been able to spot from a OEM injector. I think, but have no real proof, that KERMA does have the ability to cover his tracks. Please do not ask why I say that it is just a gut feeling from a few things he has said and his record from the TDI club. That said I think it is still a little risky, but so is just driving the Jeep.
One thing to remember is these CRD's have been rather problematic and may be watched closely by D/C for all we know. For those with a 3/36 warranty the chipping is really a no brainer after you are close to the end of warranty mark, the 7/70 guys may want to let the 3/36 folks be the testers of the waters.
I have been ask on several different ocassions about being beta test for chipping and have always had to pass either because they could or would not answer some hard questions (my computer days started in the early 60's and taught computer repair/service at HS level before full retirement) or in the case of our CRD it is the wife and daughters daily driver, with me only driving on rare ocassions and I do not have the equippment/programming any longer to do a proper betta test.
Ok, now you know my opinion of the chipping question and why. If I had the dispossible income to pay for some repair that D/C might not warranty because chipping was discovered, then yes I would jump on the chipping and for sure injectors. Remember a single injector replacement will cost over a $1000 to replace at the least.
