Customer Questions and Answers


Question:   I'm a tech (16+ years at Ford, diesel) and have a customer’s 6.4 that has the oil temp increasing with no load regular driving/worse under load. Cooling system is premium and has had the front cover removed for block inspection (no build up in block), cover had very light cavitation so cover/pump/t-stats were replaced.  This was done after oil cooler replacement. Oil pressure is in specs. It has the cat/dpf deleted and has your GBZ-FD40 installed. The only pid I see change is the dpf load state. The oil temp increases at a greater rate when pid shows loaded or clogged.  Question, why does this pid change with your programmer or is it supposed to?

Answer:  The FD40 program does not make any changes to the PIDs.

Question:  Hello I just bought the EM 1.0 with the plus tune. I plugged it in and it won't give me the choice to turn the dpf, cat, egr off. I was able to download the tune and change the tire size. But I can't change anything else like cold air, egr, dpf, cat delete.

Answer:  Maintenance mode should take care of all that.

 Question:  Hi I bought a tachyon+ kor series programmer for my 08 6.4 off eBay. The seller said it worked great, what he didn't tell me is it's locked to another truck. I know this isn't your problem seeing I didn't buy it new from you but is there anything I can do to reset this? If I can send it to you and have it fixed for a fee or is it cheaper to buy a new one? Any help would be greatly appreciated, thank you.
