The K-Pro Thread

[NVA-AV6]

Ok guys, here is my take since I am the one giving Brian his info and direction. I personally don't liek the idea of the dual ECU setup (I have done this in the past on other vehicles) it just seems a bit clugey to me, but I understand completely why it is used and my hat is off to cham for making it work for the A4s. FPro just seems like a much more elegant and cleaner solution for the A8s since the Si ECU has the full support needed to also run the 7.5 gen Accord. If Brian was a A4 I would have just suggested to go with the known working solution, but I look at the A8 as a oppertunity to at least IMO come up with a different solution that will be a bit less expensive and have less parts to fail.

Paul, thanks for finally coming on scene with us.  I know you are the brains behind the operation and it's good that we can have a dialogue about the EMS that you and Bryan have chosen.  I see why you have chosen the EMS that you have, and I wish you the best of luck.  In truth it may be a bit more elegant than having a Kpro, I'm just worried about the wiring differences between the K24a8 Accord and the FJ Civic Si.  I know both models share the same ETC system which means you won't have an IACV difference, but I am unsure if the Civic is MAF equipped.  I know you've thought about the possibility of having to revert to an Si engine harness, so I'd like to see what your thoughts on the matter are.  I'm not against Fpro, I'm just very wary of it because it's never been tested with an Accord engine harness, which I'm sure is at least somewhat different than its Si counterpart.  

You have my phone number, please keep me updated on the situation, I am more than happy to lend a hand if needed.

Skip, the 06+ si does have a MAF and using Fpro u can tune off of a speed/density map kind of eliminating the MAFs signals anyways

As for what you said about Kpro w/ Cham's harness on an a4 Tim, I agree it is the best solution and my whole presence in this thread originally was to ask why people havent attempted to use Hondata's proven harness for the Element, sorry that was a lie! Encourage research and for someone to look into it and now I know why it is not used. So thank you.

Furthermore I dont know why its a problem to investigate Fpro for use on an a8 when neither Kpro or Fpro have been proven to work on the engine. I do not believe I have but if in the past I have encouraged people to use Fpro I apologize that was not my intent, this is R&D work and a POSSIBLE!! solution for a8s and thats all.

Lastly my intent was not to disrespect or bash the validity of Cham's work, as said previously Ill be attempting to use one of his harness' if this project does not work.

I'd just like to point out that the OP has a K24A4, so this K-Pro/F-Pro debate is a moot point.  The reason why I got involved is because Bryan was posting incorrect information based on a misunderstanding.  I wanted to dispel any incorrect assumptions that Bryan had since a lot of it was untrue.  It doesn't really make much sense that there are multiple threads on the same topic.  The OP should have searched first before creating this thread.  I'd like to also point out that one of the rules we have is to not create multiple threads on one topic.  Because there is already a kpro thread that the OP didn't bother researching first, this thread is locked.

Bryan, I spit the F-Pro posts into a separate thread so you and Paul can continue to update your progress and help others.  I understand your reasoning for wanting to use F-Pro and hope that your and Paul's R&D comes up with positive results.  We all want to make more power and F-Pro seems to be another good solution to tuning K24's.

[BliNx197]

So to rephrase my question a Y-harness (the ones that Cham makes for an a4) can be used with a few simple changes to run on an a8? I did state that you probably would not have to include an engine harness from an a4, if Im wrong on this then why is Cham saying theres a possibility to run kpro on an a8? I understand theres parts of the engines that I do not understand as well as you but is there something else I am missing or are we just saying theres no tuning solution for the a8 other than the possibility of Fpro?

I have spent several hours with both wiring diagrams and can match every sensor signal and HVAC signal between the two cars, so the route is to take to extension harnesses (one for the A8 and one for the SI and splice them to make a conversion harness. Both cars are MAP and MAF equipped and in fact use the same sensor part numbers including the O2 sensors, so I am very confident this will work......

SO AS I KEEP ON READIN HERE I KEEP SEIN THAT CHAMS HARNESS WOULD ONLY WORK WITH K24A4 BUT NOT WIT THE K24A8..HUH.

As I also said in the F-Pro thread, please do not type in all caps and use proper punctuation.  It's hard to read everything in all caps.  For those of us that communicate using the english language, it's easier to understand what you're trying to say when you use proper punctuation, instead of one giant run on sentence.

[k24cm_5]

im sorry dude.i didnt mean to get anyone mad..

[timot_one]

Nobody got mad man.  Just trying to let you know that most people will not pay attention to you (except to give you shit) if you post in all caps all the time.  To answer your question, we do not know whether or not Cham's harness will work with a K24A8 yet because he has not tested one yet.  Fortunately, there is a local member here that would be a prime candidate for testing.  I'm glad that both of them will be at the meet I will be attending tomorrow.

[k24cm_5]

oh ok. so its in the process of being tested..good

[timot_one]

No, I'm just trying to set this up right now so you K24A8 guys can have a good EMS option.

[timot_one]

Here's another thing I thought I should mention about K-Pro.  I know Cham has dispelled the myth already, but I thought I should show this to the guys that have to get an inspection done.  Right now I am running K-Pro with no CEL on my dash.  Here's the proof:



I opened up the gauge cluster the other day, got inside, and covered the OEM CEL with a small piece of electrical tape.  After that, I modified the plastic part between the PCB and the black plastic for the gauges so I could run a LED in the OEM location.  Now I'm using the CEL that is connected to the K-Pro ECU and it looks and functions totally stock.

Awesome stuff there Tim.

good stuff tim ^^
