Nissan ECU Tuning

Hi all. Firstly my name is Jarryd and im from Australia. I do not know if this is the right section to post so please dont flame me if its in the wrong section. I have a jdm s13 silvia with a ca18det. I have made a tune for my following mods

CA16DE inlet cam
T28BB from JDM S15 slivia
Walbro 550hp Pump
FMIC
444cc GTR injectors
RB20 AFM (old Purple lable)
3" Turbo back exhaust with 3" cat

Now I am having trouble burning the new tune i made to an eprom. I am using a willem dual power eprom burner and a 27C256 chip. When ever i go to write the chip i get a 0x00000 chip 0x00 Buffer 0xFF error. Sometimes i can burn the chip but when i check to see if the chip is blank it reports back and says that it is blank.

Should I just put the eprom into my ecu and see if it works or is there something wrong that im doing while burning the chip. If anyone has a guide or can help me with this problem that would be very appreciated

I have also uploaded the tune i made so if you could have a look at that it would also be great.

First, get a different eprom burner. I've gotten mine to work but only with SST EEPROMs and you've gotta basically trick it into working. It's not advisable you put the EPROM in there either, sometimes they can make badness happen with your ECU if they aren't burned properly.

Darkhalf on here sells a board for the CA ecu that offers a whole raft of features, real-time map tracing being one of them and with USB connectivity it's worth the price for the ease of use and connectivity. I've read good things about it and will be ordering one myself pretty soon. www.nistune.com

the board is fairly expensive. I don't know if you guys have heard of Dr Drift but hes one of the best CA tuners in Australia. For that price I can get the chip and get him to dyno tune it to.

Oh right, Australia, forgot about that. I've heard of Dr. Drift, just get it tuned by him then Razz

That means i have to get my car towed to him Razz

I just wanted this eprom burner to work so i can save some money by installing the afm and injectors myself.

I found my problem its because i cant get VPP voltage to 12.5V. For some reason the max i can get is only 4.27 and i cant adjust this but turning the little blue pot.
