Alright after a lot of research and looking at possible solutions to tune a k24a8 engine I and Paul both have decided to look into using Hondata Flashpro with a conversion harness. This will be updated as information is gathered

Plan: To use a stock k24a8 and a k20z3 harness splice into them, mate them together at the appropriate connections to have a k20z3 ECU run my entire car. After this has been done we will be connecting my Flashpro. hopefully there will be limited CELs but FlashManager comes with a Code Checker as well. But if this is a possible lost cause then I'll know and be going another route to run my Frank!


Outcome: Fail

Project Cancelled: No questions please!

Its just not feasible on a production and plug and play scale for the amount of time and money it would cost to possibly run this setup. Ill be running a different EMS on the frank, prolly Kpro and am currently in the process of acquiring one.

Thank you

kool!! Hopefully it works good. If it does we need someone with a k24a4 to do it. I want to add more mods and get the most of out it with a good tune.

All the best of luck from my neck of the woods...I just hope that you didn't just make an $800 mistake...

No! possible $700 mistake, hondata softened the blow, and as for the a4 im not extremely familiar with all of its wiring maybe it will work but ud need to get a MAF sensor like the a8s and z3s,.. once I get the results ill post a new thread on it in conjunction with Paul,... if this bears fruit, all prpbabilities are looking positive tho, I am curious as to the range of the a8s primary o2 sensor,.. the part # is very close to the z3s but maybe that's just all primary o2 part #s I never checked it against the a4s, ill prolly do that soon.

just checked it, same o2 sensor between the a4s and a8s,.. prolly gonna need the z3s for this.

At least you know that you can get the primary AFR sensor for an RSX to work.  I double checked the part numbers for the A4 and A8 and they are the exact same part.  There is some speculation that the primary AFR sensor may not be a narrow band though.  As far as I know, it's been questioned, but never proven.

yea the rsx primary has been proven to work with kpro and an a4 but those like rsx ecus are in high demand as far as I know nowones played with the z3s parts. less demand prolly which is a primary reason I've hopped all over this fpro solution, alright enough speculation, ill keep u all posted, later

no worries my accord is an auto with the MAF. Hopefully it does work out for you.

If you're going to be using a Z3 ECU, it makes sense to use the primary afr sensor that would go on that car.  Go with the Civic Si primary afr sensor and see what happens.

Best of luck man. I really hope that it will work out with you.

FPRO is designed for hondas/acuras with dbw, if you want a tunning options you should probably go with kpro and chams harness.

id say the same thing,.. but hondata has said they don't actually have control over DBW im getting the idea that the ecu just needs a signal from the tb,.. not gonna rule it out. But the z3s ecu and TB control are internal,.. oh well still got some time to wait on this one!

Blinx have you been working on another way to hack into the a8? I have the shop I'm using looking into the kpro dual harness idea. See what they can come up with.

I think he's still working on getting a couple of other things going to make this work. Try shooting him a PM.

I've split the F-Pro and K-Pro discussion.  Please continue the F-Pro discussion in here.  I would love to see you guys provide as much information as possible so that others can come here for help if you are successful in getting F-Pro to work.  I hope that this can become as helpful and informative as the K-Pro thread for people that want to do this when you get this to successfully run the K24A8.

Agree, I am doing this work for the A8s only, this option does not make sense for a A4.

GOOD LUCK WIT THIS..THIS WOULD HELP OUT SOO MUCH SINCE I HAVE A8 N THERE ISNT MUCH OBTIONSWHEN IT COMES DOWN OT THE TUNIN

Please don't type in all caps and try to use proper punctuation.  It's really hard for those of us with poor vision to read.

Anything new on this? I'm watching this topic like a HAWK! If this works I might just throw a party I'm that damn happy lol.

any progress?

I don't know if anyone saw it, but the OP got updated at 3:30 pm on the 13th. Consider this a free bump.

so this migt just weork wit our cars...wit the k24a8..oh yeah

i mean this fpro setup might just work with our dbw..good

I think it MAY work is what he's saying. I get the impression Bryan/Paul are saying there is a high chance this will work but it will only work for our cars, the same way Chams harness was. HOWEVER because of how much work and time went into it the harness may not be duplicated...correct me if I'm wrong Bryan/Paul. If I'm which I hope I am if this works out and you are 100% sure it will work for the stock a8 and possibly work on auto's consider me number one on that list lol. Keep us posted on this I check this thread almost daily in hopes some day I too can tune for F/I

Sorry man, I already got first dibs.

Oh that snot even cool. How about joint custody? You can get it weekends lol. I'm willing to get on a list if it works out, have to pay to play right.

Haha. I'm just happy that there might be a solid tunning solution for us. The hardest part is creating the harness so if paul doesn't want to make the harness, maybe we can talk him into providing us with the ecu pinout diagrams so we can do it ourselves.

Yea that would be fine by me. With the pinout I can take it to the shop and they can possibly create it while working on the car.

no update?

2nd that any updates?

so it didnt work.i guess ill just keep on waiting

sad to hear. you know im goin to bug you this weekend blinx, ive got lots of ?'s.

Bryan, you may want to contact Cham.  I believe he won't be too far from you for the next few weeks.

Chams harness will work for you if the dbw pin is anything like the TSX's it will work. I am REALLY sure that chams MT harness will work for the a8 guys. Hondata leaves connectors B and C from the stock harness connected. Everything else A,D,E connectors should be the same or really close maybe 1 or 2 pins need to be hooked up.

I'm about to turbo my a8 next month. Ordering a few misc parts then it's going on. I'll be using Haltech but if Cham can make it work for the a8 auto then I'll be the first one tearing the Haltech out and putting the K-pro in lol

For you a8 guys who dont know Im officially using Kpro on my car now, swapped to a RSX-S TB I got for like $120 w/ sensors sweeeet deal! and Im currently back to breaking the engine in fully before tuning, Im sure Paul will be doing a more detailed write up on this sooner or later once my car is 100% complete but, just a heads up!

Glad to hear that your car is up and running and that you're successfully using kpro.  This makes things a lot easier for K24A8 guys especially since I recall seeing you post in another thread that doing a DBW to DBC TB was easy.  I'm glad to hear the solution that I proposed worked out for you, since at the time it was only a theory that couldn't be proved.  Thanks for you and Paul pioneering a new solution.  I'm assuming that the pics Paul posted of the RSX gauges were of your car.  Did you get your climate control to function too?

Oh I thought the fact that it was my car with the gauges was obvious but yea everythings working except for the Speedo and fuel gauge at the moment, have to get 2 other sensors for those.

The Cable TB was fairly easy (not in my case, Paul did some serious work to get that TB to fit!) but for those prepared in the future it will be. HVAC works like it did the day the car was purchased and THE FRANK!

 IDK where to start with it, Im dying to take it over 4.5k but I wont before atleast a 1k breakin is fully done, and prolly not even until 2k to dyno it. Honestly at about 20-40% throttle under 4k it just goes, theres no massive tq rush or wheels spin the thing just grips and accelerates like the cars lost a half its weight.

Ill try n post pics and videos tomorrow

Good stuff.  Time to get driving and rack up those miles.  Come up to MA so I can check it out in person.
