Kioti Tractor Tuning

[Threepoint]

It probably would cost the same to move up in tractor size and power as it would to try power up the tractor you have...
If you don't have enough power... get a bigger tractor..

Yup, price point for up-tuning is the key as to whether there will be much demand for the after-market capability when it becomes available. If the cost ends up around $2,000, and the choice is between, say, buying a new NX4510 and a new NX6010, then I think you're probably right. But I doubt that would be the market. A likely adopter would be an owner with a low-hour, five or six year y/o NX or DK with added accessories/mods who doesn't want to trade out for used with more power and risk ending up with someone else's problems. Seems to me that trading up to a dealer for a new model with an identical engine with 15 hp more would be a way more expensive option!

The thing is... Does someone have a proven power up..?
A power up with proven testing and a warranty on the product...

Not to my knowledge.

Greetings, All,

Just a note of appreciation for all this discussion. I have lurked TBN for a while, contemplating the purchase of a tractor. I am attracted to the CK2610 specifically because it seems to hold potential for aftermarket up-tuning. I would not want to invalidate the warranty, but it would be a fine thing to look forward to an increase in power following its expiration. Having been involved in both automotive and computer hot-rodding, it seems so odd to me that we don't know more about how to tinker with tractors to coax better performance out of them. This thread is an important move in the right direction, I think: So please, keep on keeping on!

The new 2610 has the exact same engine as my 2014 CK35 1.6L. I believe it is not common rail just a standard plunger actuated injection pump that has been turned way back to get below the 25hp limit on tier 4. All you would need to to is turn up the fueling screw and you would be back at 35 hp easy.

See picture
Remove cover screw in 2 turns test machine and under heavy load look for black smoke, if none turn up more. Once you get to the point where you see black smoke under heavy load back off the screw 1/2 to 1 turn. Best way is to use a dyno for an accurate measurement. Good video on it here.

I'm wondering if a half-volt zenor diode soldered across the pressure sensor and a test tube installed in lace of the DPF would do the trick or if the ECU is smart enough to want to see a variable voltage comming back from the pressure differeial sensor. On page 12-77 of the service manual a 5 volt reference signal is sent out to the differential pressure sensor. Then:


"The differential pressure sensor detects the pressure difference between the inlet and outlet of the CCRT and sends a signal value of 0.5 to 4.5 V to the ECU. The larger the pressure difference between the inlet port and outlet port is, the closer the signal value gets to 4.5 V. The smaller the pressure difference is, the closer the signal value gets to 0.5 V."

The manual shows a picture of a DP5000 pressure sensor. I tried to unsuccessfully track this sensor down through Google, but it is the white wire that sends the signal (modified reference voltage) back to the ECU

Perhaps the internet can continue to puzzle this out frther.

And here a theretical way to build a circuit in place of the pressure sensor. Unfortunately, the Analog Behavioral Modeling is a little beyond my current skill-set.

Voltage-Controlled Resistor

I've also considered dropping in a digipot, but again, I don't know if the ECU is smart enough to kick into limp-home if it sees a constand signal or if the signal must have some variation.

Anyway, my current high nail is just being able to interface with the ECU for service work, not modifying.

I couldn't find anything on the DP5000 either, but finally think I found the Kioti part#F6800-26651

Has any one had a dealer lookup part numbers for injectors and injection pump between the different models with the same engine? I know with Volkswagen Diesels (cars) depending on the transmission and performance package they have different size injectors and injection pump.

The ck operator manual suggests that the 3510 and 4010 tractors have a hpcr fuel system while the 2610 has an old pln system.

If true, the 2610 has nothing in common with the 35 or 40 hp models.

 

[deezler]

2610 has a completely different engine than the 3510/4010. Different displacement, fuel system, etc. Probably almost zero common parts.

It would still be nice to know if the 2610 could get juiced up to closer to 30 BHP. Or how easy it would be to tune the 35 HP 3510 to 40 BHP instead.

I could be wrong, but I知 pretty sure my 2610 has the old pre tier 4 ck35 engine. It will make 35hp with a turn of the screw. Even kiotis international web page shows it making 35 or 34hp. Just not in the states because of emissions.
