UPDATE- Chipping P08 ECU - DEFINITIVE info

Ok, as the title says, I need some confirmation on the chipping locations.

To give some clarity to the situation, I have a JDM Chipping Kit from xenocron that I bought. I've visited their tech pages and there is no definitive page I could find for a P08 ECU Chip [how to].

I found a link on PGMFI but that was for a P30 ECU. Ive also seen the one for the P28 in the DIY section but mine as expected is completely diferent.

What I know:

I've got install the DIP socket, the chip for the area circled [see above] and the 4 pin CN Datalogging Header. Thats it for the front side as I've gathered.

The BACK of the board, this is where i have an issue.

I know C49 and C50 because its marked on the packet i got from Xenocron. Do I put the other one capacitor on C92 as this diagram shows? also, I have a resistor. Where does the go and Do I have to jumper J1? because it isnt "closed", jsut 2 holes with solder in them.

Take picks of the inside of your ecu and the chip kit and all its components. I think the resistor you are talking about is a 0 ohm and goes in j1 but I am not for sure with out picks.

Put C49 and C50 on, you dont have to worry about the other capicitors. it works fine with out them. this is how i did my last couple of ECU's. I also enquired with Xenocron and they said it would be fine doing it that way.

the resistor is for auto to manual.

use J4 when you remove it (for data logging) to jump J1

the hardest bit of the whole thing is soldering up the Latch IC. its a right bitch to do. you USDM guys have it easy

OK I did everything except move J4 to J1 and neptune connects but I'm not getting any Datalogging. I can d/l and up maps it seems but no datalogging. So, I'll get the J4 soldered on J1 and hopefully that will do the trick.

Thanks for all the info homie. BTW I'm not in the US, but from Barbados. Strictly JDM goodness over here lol.
