Inquiry about ECU Compatibility with KPRO v4

Post by turner2f »

-

Hello Hondata,

I have a 2003 Acura RSX ( Base model ) with Automatic Transmission.

My ECU part Number is 37820-PND-A56

========

I am planning to do an " Auto to Manual " conversion swap on the transmission

I am also planning to do a K24A2 engine swap

========

According to your article at ...

https://www.hondata.com/tech-alternativ ... ngine-swap

" With the KPro4 it is possible to use the 2002-2004 RSX base auto ECU.
This will only work for engine swaps. "


" We install the manual transmission code into this ECU. "


QUESTION 1 :

Will my ECU work with KPRO v4 for both the Manual Transmission conversion and the K24A2 swap ?


QUESTION 2 :

Will my ECU work with KPRO v4 for JUST the Manual Transmission conversion alone by itself

( without doing a K24A2 swap ) ?


QUESTION 3 :

What is the turnaround time to get KPRO V4 installed ?


=======

Thanks in advance.

.

QUESTION 4 :

I am wanting to use my AUTO ECU because Manual ECU's are very expensive to buy, hard to find, and expensive to program to my key fobs.

Are there any " significant " known issues with using an AUTO ECU ?

Such as with the speedometer or cluster ?

If, yes are there any " significant " known issues with NO solutions ?



QUESTION 5 :

Which Manual Transmission harness would I need to get ?
  • I have a 2003 Acura RSX ( Base model ) with Automatic Transmission.
  • My ECU part Number is 37820-PND-A56
  • I am planning to do an " Auto to Manual " conversion swap on the transmission
  • I am also planning to do a K24A2 engine swap

EXAMPLE : A Manual Harness from a RSX Type S, or would a Manual Harness from a Base RSX be fine ?

=======

Thanks in advance.

Apologize for reviving a very old post, but I have similar questions.

I'm also doing an auto to manual trans swap on an 03 base RSX.
(Trans swap is to a W2M5 5 speed - the one out of the original 02-04 RSX base manual)

ECU 37820-PND-A56
I have a manual harness to use for the project

Seems like Kpro4 should work fine and from the "KPro Alternative ECU for Engine Swaps" I just need to manually connect the VSS signal wire to the Kpro patch harness.

My question is, on the patch harness it looks like there's about 9 other wires coming out. Where do all those need to go?

Alternatively I could get a PND-A06 ECU and immobilizer bypass for the project to work, but that's a whole lot more money when it seems like all I need to do for kpro on my current auto ECU is some de/repinning and some soldering.

I'm not tracking there should be any other issues?

Side question - to get the prior reflash discount what documentation do I need? or do you just look it up based on the serial? (I currently have the hondata auto reflash. love it btw)

Happy Thanksgiving

Hello Lucky16.

A little over a year ago I sucessfully swapped my transmission.

Invested 6 months of reserch toward parts, purchases and labor.

Throughout all my research, there was no clear mention that the KPRO V4 might cause the "readiness codes" to erase everytime my ignition was turned off at the smog shop. In other words, it would no longer pass emissions because the ECU was not getting constant power when car was turned off.

I feel it was the KPRO, but could have been something else.

I had to sell the car within 3 months before tag renewal was due.

Happy ending was that I got into a Toyota 86.

====

What I am saying is that if you live in a smog county, be prepared to lose your daily, or to sell to a friend in a no-emissions county.

All the best.

Let us know how it goes.

Interesting
Sorry you had to sell after all that work - I know it's a lot

When you did your swap did you get kpro on your auto ecu or did you buy a manual one?

Right now I don't live in a place that does smog checks but that may not always be the case

I purchased a Manual ECU from eBay, and sent it to a dealer that then added the KPROv4 to the ECU.

I have read other forums where other folks had their readiness codes for emissions erased when the ignition is turned off after they installed KPRO.

One other thing I was not told was that you will need to get your car tuned for idling.

Whenever the A/C was turned on the RPM's would drop almost to the point of the car stalling.

No one told me, so I am passing this info along to all that can benefit from it.
