Believe us; we would like to make a KPro for the 05-06. We would love to eliminate the harness, ECU and o2 sensor and associated costs of these parts.

Unfortunately the ECU was changed so that it is not possible to make a KPro. It is not a matter of spending time or money to make a KPro ? it just cannot be done for technical reasons. It is not because we want to make more money or punish 05 owners.

We have offered a solution so that 05 owners who want to run a KPro. The cost is higher but that is unavoidable given that route we had to take.

I for one appreciate you taking the time to respond to all of these inquiries on the 05-06 KPro, nonexistent as it may be.

However, I would appreciate it, and I'm sure I'm not alone, if you could elaborate a bit more on the technical issues you are facing in cracking the 05-06 ECU. As a full time EE and Embedded Systems designer and programmer, I face electronic design issues every day which I'm sure are very similar to yours. I've designed and developed an ECU of my own for a SAE competition using single cylinder applications and I can understand the challenges involved.

Are your problems embedded software related? Are you unable to reliably program tables in EEPROM or FLASH? Does the new ECU hardware lack a programming interface you can access? I'm sure with some detailed information on the problem, those of us who are technically inclined could provide an explanation to the community that would significantly decrease the traffic of inquiries you are seeing while presenting a solid technical argument for abandoning the 05-06 KPro option.

I have not been able to find a straight answer on whether the 05+ krpo adapter will ever become available again.

What are plans in making this available to the public again, and if it is currently, how can I order one? My current dealer indicates that it is not available.

Thanks.

Given that our OBDI intellectual property has been illegally copied and incorporated into competing products, we're not going to release any in depth technical information on the ECU.
The 05 ECU is different. A KPro type solution is not possible. It is not a matter of overcoming a technical hurdle, or reading the ECU, or anything else; the ECU is different from the 02-04 and a KPro solution is not possible. You'll have to take our word on this.

Probably before the end of the month.

There is only one known issue - the speedometer wanders around by about 10% at times, and the cruise control is not steady at speeds over 70 mph. The product is still usable, but we wanted to make sure everything else was working (at first there were a number of problems but these were traced to a couple of incorrect harnesses).

OBDII must be switched off as the purge outputs are different - for some reason people are reluctant to do this. Switching off OBDII does not alter the way the ECU runs, and will not harm the ECU/engine. The engine still runs in closed loop.

Thats good. Do you have any plans on fixing the speedo or do you see a way to fix it? How severe is 10%? If I'm going 80mph could it suddenly say I'm going 88mph or even 72mph?

What does "not steady" as far as cruise control mean?

Do you know what dealers will be offering ECU packages (ECU and harness)?

Thanks.

One other question - If I were to buy/supply an 02-04 ECU already loaded with KPRO, to be adapted to my 05, could I just buy the harness and/or would there be a discount involved in retrofitting it to work with my 05 - provided I could use the 02-04 KPRO ECU?

We're working on the speedo problem now. It is mostly OK but will read about 10% low in 5th gear for some reason.

The harness on its own will not work. The ECU must be modified as well.

Any plans for discounting supplied ecu thats been kpro'd?

If you supply the ECU for an 05 RSX which has already been prepared for KPro then we can modify it, included in the cost of the harness ($200).

Let me make sure I understand.

I buy an 02-04 ECU already loaded with KPRO. I send it to Hondata and then you/they prep it to work with my 05 ECU and send it back for only $200?

If thats the case, I'll jump right on this!!

I believe you'll still have to pay them for the harness.

If you have an 02-04 ECU with KPro then the adapter harness and ECU modifications is $200. See our other post about changes for the 05 KPro.

Does said modification prevent the 02-04 ecu from being used in an 02-04 from that point on?

Thats a really good question.

on the purge valve operation cell I have set readiness and so far I have not gotten a cell for it
I'm hopeing the by setting readiness it does not look for it anymore due to the test being complete or have I just been lucky. 900 miles no cell (since the last time I uploaded a kal)
