D17a2 ecu?

nindoo, DaX is not an employee nor representative of Hondata. Don't take his/her opinions as ours.

I don?t think most people realize the amount if work it takes to reverse engineer an ECU, the build hardware and software tools to expand the ECUs capabilities and to allow people to tune the ECU. We have evaluated what options we have with the D17, and have determined that the only economically feasible option will not work, so it is unlikely that we will develop anything for the D17. If it helps to give an idea of development time the RSX took almost 2 years. Your estimation of investment payback is out by an order of magnitude. Sorry. If anything changes, we will let you know, as we would like to cover as many models as possible.

The development approach we tried did not work.

hondata would be nice on our 7thgens

I should have made it clear that I was merely stating opinion. No...not an employee here...just a wrencher with an opinion the size of Texas. I do not sell any products or services at all.

And Dax is a him.

please make one... please make one... please make one for all pleaseeeeee!

(d17a2 boosted w/ no hondata ecu)

<<<me for a long time now!

Thank you for your response. I guess I was a little to harsh, I'm sure if you could make the ECU you would have done it.

Yes - I think its known that reverse engineering an ECU is not an easy task. However, there are so many similarities between the 7th gen civic and RSX its not funny. I don't understand why it would be much different for their ECUs? The fundamential designs of the circuitry, EEPROM they use, etc - should be similar if not identical - Both use the honda PG to program through the OBDII port, meaning they should use the same communication protocol - which means that you guys (if you have truly reverse engineered the K20 ECU) should be able to figure it out with no sweat.....

I'd be curious to know what the real reasons are.....please elaborate if you have time. I offered my assistance earlier as an engineer, and I wolud love to know what the deal is.

First off I just wanna add my two cents, Crower is releasing their product line for the D17 in late Dec 04. This mean that a lot more owners of the D17's are gonna build all motor or turbo applications. (It's a hell of alot cheaper than a Kswap) and Crower is gonna cash in on a market that they aren't gonna regret...

There aren't much option out there for tuning the D17, and from a business standpoint Hondata IMO operates purely on a basis of choice, because if you guys (Hondata) designed the "K Pro" which require a lot more reprogramming because of the iVTEC, then to design a ECU for the D17 is totally possible.

Secondly if I was to say that I will fund Hondata's R&D for the D17's and make available the necessary vehicles for their testing (both boosted and NA) but when their product is released I would like in return 8.5% of every ECU they sell. How does that sound because technically if Hondata claims that it is not feasible then I am willing to take on that risk as well.
I wonder what their excuse will be now

I will fund Hondata's R&D

Believe it or not, this happens quite often, but people have no idea of the cost even a 1 year development project. So tell us, how much money are you willing to spend? The reason I ask is that you probably have no idea about what it costs to reverse engineer an ECU.

You're made you point collectively, but our earlier post sums everything up. Please stop posting trying to encourage us to look at the D17 - we have, and at the moment nothing is possible. If there was any way to economically create a solution for the D17 ECU, we would. After all, that's what we are in business to do. If we cannot create a solution, either for technical or ecomonic reasons, there is no need to be angry with us.
