I was just sent the compare report of the de-mandated program that was in Mikefish34's truck. The tuning supposedly done by a "Doctor" guy in effingham, IL. I will not mention name but Mikefish34 knows who did this to the truck.

I think guy that did the tuning needs to re-name himself to "Mr. Hack-n-slash" instead. It would be more Appropriate for what he did.

The compare report shows >>

=* File in engine did not match the truck. Not just calibration but the whole intake, airflow, exhaust, injectors, and all other setting for the truck was for different brand, model and make of truck all together. Maybe was copied from another truck? Anyways, program was not set for this truck at all. Makes fuel mileage poor and engine run poor when someone do this for wrong air flow into and out of engine and for injector too.

=* All mapping and fault codes for VG turbo was suppressed including overspooling, overtemp, speed, everything. I guess they might have did this so it could be unplugged and replaced with after-market and/or plugged back in and engine would not show faults in dash?

=* Turbo was set to overspin really bad and was set to strengthen engine brake to the point of destruction. Mikefish34 maybe avoided this destruction by putting on a after-market turbo. I bet he lost all jake when he did this. Manual turbo must have made engine not run so good either = What kind of monster hack-job tuner person would do this to engine?

=* From what can tell, engine still set for emissions and fighting the itdelf to make with no more egr valve. De-mandate was only just enough complete to make codes disappear and computer was still fighting this. Not so good for well running motor.

=* On time and other injector settings were not right for this motor setup. File must have been from different motor with different injector. Computer had no idea how much fuel it was putting into cylinders. Incorrect injector settings can make a truck show higher fuel mileage in dash than normal, make black smoke, black oil, high EGT, run rough at idle, and a lot of other problems like allowing cylinder pressures to get high enough to destroy engine if run really hard.

=* Because injector data was way bad, the compare report also show cylinder data so far out of whack that there was no more engine cylinder balancing. ECM was trying to back the fueling down but ran out of allowed range so it just maxed out all settings. Looks like data got corrupt because computer was trying to compensate for fuel it did not know about. The numbers normally sit in the 100~200 ish range and vary according to cylinder on healthy engine but this one was sitting above 850+ and maxed out.

=* Exhaust manifold pressure feedback was overridden and set to 0 PSI. Engine could not compensate for exhaust air flow nor tell if air or cylinder pressure was excessive and harmful to engine.

=* I was told that Mikefish34 asked for 500 hp max. This was the Power setting that was set. HP is more than 1,000+HP and 2,430 ft lbs torque. I guess guy does not know how to calculate HP? This is beyone crazy wrong. This is table that was in truck ..

Engine way over-fueling and had lot of vibration from what I was told. no wonder, it was trying to tear itself apart. Also a sudden surge in torque at 1200 RPm. I bet it was wonky to shift and drive at that speed.

=* Injection timing was set for +10 to as high as +12.7 degrees BTDC at the higher torque. This was at 1300 rpm and all the way up past 2100 RPM. Detonation problems would have got this engine after a while for sure.

There is several other minor settings that show maybe someone did not know what they were doing and were poking around. Not very professional to leave that kind of thing in engine with unknown outcomes.

Program was definitely not set up right. There would have been engine carnage for sure on this one after a while, especially if someone tried to drive it hard. Maybe Mikefish34 can comment on what was done to this thing by the guy in effingham, perhaps tell his story. I heard he had an argument or 3 with the guy, not sure. Hopefully someone got him straightened out before any damage was done.
