I answered this on k20a as well -- you have to turn the engine off, put it back in the on position while not started, upload a new map (ctl-u), then start the engine again.

not being able to live tune is what makes K-PRO crap on a loading dyno. Especially tuning part throttle timing and getting the car running smooth is a nightmare. I am a full time loading dyno tuner and have been tuning over 100 cars in the past 2 years, and setting up K-PRO without a based map for over a year and still haven't got it right.

live tuning is badly need for the K-Pro, the are times that i can upload map without restarting the car, e.g. fuel changes, but it is very inconsistent. i hope the guys at hondata are working on this, and also i hope that they add some more features that are in the s300 in the k-pro, i really love overlays.

Realtime programming of a K-Pro is not possible. It's not soemthing that can be worked on. THis is due to the type of processor used by Honda. If you have complaints talk to Acura/Honda.

8) Go easy on us, we don't know the details like you guys. Thank you for the heads up all the same. I was thinking that you guys just have not gotten it to work right. As i said, i am very happy with it, "realtime" and more overlays are the only things i wanted. now i know realtime is not going to happen.

This is not a valid claim:

To begin honda never intended its ECU to be internally piggybacked upon with a slowish 8 bit PIC micro. Surely honda and mugen do not tune their engines the way we tune K-PRO in the dynopull-edit-download-GLITCH-reboot-dyno pull method!

It is more like hondata cut cost on the hardware. If the micro had sufficient speed and ram, real time programming would have been possible.

K-PRO is an overpriced piece of junk for what it is. Hondata is not sure how the AFCMD works, does not know how to include retard based on IAT, claims tuners don't use autotune, downgraded inteligence of the Honda ECU by removing knock retard, to name a few.

Robyn, most of what you are saying is not true.

Thousands of other KPro users manage to successfully tune their cars on the dyno - I'm sure you can too.

The processor Honda uses in the ECU uses flash memory. It cannot be updated without suspending the operation of the ECU. The only way to make the ECU real-time updatable would be to change the ECU processor and memory type.

The factory behaviour of the ECU is to not retard on knock - this is something we have not changed or downgraded.

Nobody knows for sure how the factory knock retard works, but it sure does prevent knock from destroying an engine, even with a turbo added.

We have tried piggybacking a stock honda ECU by manipulating the MAP sensor on a turbo setup, without tuning timing, the ECU seems to be able to accurately create a knock retard map and works flawlessly.

If I were to do this piggyback setup on a hondata flashed ECU, I am pretty sure it will damage the engine.

The way you explain how a piggyback works on your website, would be true if that setup were used on a knock retard disabled ecu such as your K-PRO/reflash. But that will not be applicable if it were done to a bone stock honda ECU. The timing will not be advanced as how you mention.

i tune live...just give it some gas and watch the rpms while uploading, its faster on a dyno also because u dont have to wait for the ecu to go out of 0 degrees.

I also have no issues tuning K-Pro. Just because it takes a bit longer to tune doesnt make it junk. You should be happy as a tuner, you bill by the hour right? Besides, what is the alternative? AEM? which takes much longer to tune with less than stock driveabilty.
