my virg p28 already has factory chips. what do i have to replace? xenocron kit
my virgin p28 already has factory chips...what all do i have to replace? i know i have to replace the IC3 main chip for the socket...obviously, but what else? the C51 and C52 already have the ceramic disk, the J1 already has a jumper (which ill replace with the one in the kit), the IC4 already has a 74HC373N chip, and the R54 looks like it already has the correct resistor.
should i replace the stuff with what xenocron sent, or should i leave stock stuff in? also, he sent an enormous 35v capacitor, where does it go? i can't find it in any writeup of chipping...or is it for an obd0? also with the datalogging piece, does it go in CN2 holes 1-4 or 2-5? |

You have to get the stock chip out and then put the socket in there. Other stuff leave alone. The datalogging goes from 1-4

leave the stock stuff there...desolder the eprom and solder in the DIP socket.

real quick, what was that 35v maroon/brown cylinder capacitor for?

It goes in spot C14 i believe. Near the ecu plugs. |

listen to the man he knows what hes talking about.and if u have to ask what it is u shouldnt be installing the ZIF send it to xenocron.
anyways, maybe ill sell off the rest of the kit. paid $30 bucks for it, and apparently only need 2 peices from it...sucks for me! |

i dont think he meant that they re-burned that chip, i think he meant they added that chip when they wanted to update/change something (just like we are doing by chipping ecus to make them run different motors, etc) [/quote ahhh! i see what u mean now i must have misunderstood him. |
