Kioti Tractor Tuning

[finn1]

Would any extra power really be substantial enough to make a reasonable difference, enough of a difference to make it worth taking the risk?

When adding more fuel one also needs to add more air. At some point a larger turbo is necessary. And depending on the amount of change in fueling (and air) the engine timing will have to be advanced (not just a change in duration of the injection). This all requires that one have an EGT gauge (and perhaps boost gauge).

I'd be curious as to whether there could be ramifications on/with the hydraulic pump. Kind of thinking that maybe it doesn't matter, but I'd for sure want to know before possibly mucking one up.

When adding more fuel, the PFP (cylinder pressure) increases, as does the valve bridge, piston crown and ring belt temperature. Advancing the injection timing further increases the pfp, and increases the piston crown temperature and piston pin bore stresses further.

The EGT reading is pretty useless, as all it tells you is the exhaust temperature in the manifold, which is not an indicator of cylinder pressure or piston temperature. Retarded timing, for example, yields high exhaust temperatures because more of the burning is occurring in the manifold, relatively speaking.

I've been trying to find someone that can change the tuning on these Kioti three cylinder turbo tractors for a while. It should be very straight forward for someone that has the proper software and serial cables to simply upload the DK60 tune to any of the DK series turbo tractors. I actually do find people advertising that they do NX and up.

Hello Everyone,

Did anyone ever figure out any aftermarket or available software to watch live data for DIAGNOSTICS for the kioti tractors with Delphi systems????

Thanks!

I have been able to read live data using two different OBD2 scanners.

First I borrowed this one. Can see codes, but not clear them, and no explanation (which makes sense because they are proprietary kioti coding).

Then I tried buying an Autel J1939 (HD trucks) scanner. It had similar functionality. Useful tool to have, but I wish I could clear codes to see if they are one-off or recurring.

I think you'll find very limited function with a generic agg hd equipment scanner. cf link below shows the limited function.

Thanks DEE and Minn

I have a couple different generic scanners and i can get very limited data or live data, none of mine will clear codes, The main thing im looking to see live is commanded vs actual fuel pressures and cylinder balance test. Ive been through a couple delphi injectors and inj pumps so far and also need a way to scan the injectors and update ecu for the new parts. I emailed jaltest to see if they can offer anything. I'm even open to buying a dealer closeout software

Don't we have a tap on the high-pressure side to mechanically tie in a test gauge? I've never looked, but there should be a provision to set up a real gage.
