P06 & P28 chipping and vtec parts list

[Stoner51]

I have recently purchased 2 ecu's I plan to chip. I am currently running a chipped p06. I added the IAB kit.

So the two ecu are a p06 and a p28.
P06 manual
P28 auto so this will require desoldering and installing a jumper?

I found an older thread on chipping ECU's by d112crzy, I have gone to digikey and dug up most of the parts I will need. I know I can get the parts from places as a kit, but like most kits they seem to be expensive. I plan to get enough parts to Chip 5 ecu's. I only plan on doing 2. But the parts are cheap.

So for the capacitors I have these parts I found from an old PGMFI thread.

Capacitors
P5518-ND
P5517-ND
P5552-ND
P5549-ND (x3)
493-1733-ND

cap locations
C14; 220uF 35V cap
C15; 33uF 35V cap
C24; 47uF 10V cap
C21; 33uF 35V cap
C19; 33uF 35V cap
C18; 220uF 10V cap
C40; 100uF 10V cap


The parts to chip the ECU:

VTEC

D11__________________1N4001DICT-ND
C60__________________478-1835-nd
Q101_________________UNR411F00ACT-ND
ICI4__________________?
It appears that the vtec component. The Ic14 is the hardest to find on the cheap. There is one company that makes them and they only sell them in 500 pc bags at 1.5 a piece. Xenocron has them for $7 a piece which is doable. However. If you get an automatic p06 you can you use one of the resistors in 1C15 or the one right below it. Unless you need the ecu to be auto. The top one is vtec and the bottom two are for the automatics.
I will be removing these and trying them. Also you can get these components from the accord ecu's. I don't have one so I can't confirm this.


IAB

Q34
Q17
Wire
On the p28 I noticed that the only thing I will need is to remove the R135 resistor and connect the wire. The p06 I prob won't bother putting this on because at some point I plan to get a Euro R manifold or a skunk2 neither of which need the IAB.



Next I need the stuff to add to vtec to the p06 but have been unable to find part numbers. Anybody have any?

And the parts for the IAB kits?

I plan to replace all the caps and convert the p06 to p28, then chip both ecu's so I can use them with my hondata s300.

Help with my questions is appreciated. And any advice would be great. I can solder and have soldered on numerous computer boards and added the IAB kit to my current ECU. I plan to buy the $50 28 pin checker to confirm my soldering for the socket.


Thanks

If this thread works out it could be a DIY on how to chip. I can add that stuff later.

The two boards so you can compare. The boards are the exact same. The components honda added to the boards make them different:

After Chipping:

You don't need the checker if you have a multimeter.

Scroll down and check with continuity!

Thanks.

Show more and circle it to show the difference for those of us that don't know.

I color coded this to the colors of the VTEC and IAB above
This is the Pic of the P06 with the components you need to add for each.

[IMG][/IMG]

If you look at the pic of the P28 above all the IAB stuff is there. You have remove r135 and add the wire.

Welll I found a P72. So i won't need to add the vtec or the IAB to these two ECU.

I did chip the p72. Before and after pictures.

This is the P06. We are concerned with the lower right corner.

This picture is the P72. It does not have a R54 slot. Everything I read said you don't have to do that.
C50, c51, the to chips and the J1 jumper and remove J12 for data logging.
This pic doesn't have the 4 pin header for data logging present. It would go in cn2 far left corner.

I removed the 2 resistors for wideband. R136 and r138


And clipped J12 to be able to data log.

I realize this board looks less than perfect however It functions fine. Not sure where all the hair and stuff came from but it does work fine.

[Stoner51]

I got another p72 so I chipped it as well and replaced all the Capacitors.
This gives me 2 p72 ecu's. One for backup.
Pic of the whole board after chipping.

The chip and adding c51 and c52.
I had my p06 chipped by some one else and they did not put c51 and c52 in. So it must not be an absolute.

This pic shows the r 136 and r138 and the j12 removed. The first two I think are only removed for hondata and closed loop for wideband.

Did you add a thermal interface material to the vreg? I always do, it only helps reliability
