Hi there, Has any one programmed their own copgy back EPROM's and then soldered them back for cars such as Nissan Pulsar 90 and VN 88 Group A Aero.?? Apparently when they are tuned correctly you gain more power than the chips you can buy for power gains.. Im trying to find a walk through or someone with some knowledge on self tuning and programming stock ECU's.. If i can find a detailed walk through in regards to removing, programming and can find a decent base tune map i might have to invest in an EPROM programming kit from dick smith for $100... Maybe that degree in Computer Systems Engineering will come in handy after all.. It should be an interesting learning experience self programming these EPROM memory chips and finding the correct ratios and timing positions... I could imagine it would be quite straight forward once the existing assembly language can be accessed and altered and i would be changing around a few array values which would correspond to the throttle mapping positions for the A/F ratios. If someone could tell me where these EPROMS are available in Australia and what type they are...(I think that the 1.8 litre 90 pulsar and the VN commodores from that era have the same type of EPROM and can be replaced with the Holden Camira type EPROM which is fully reprogrammable and i beleive is a type 808 27C256 -- dont quote me on those numbers... If someone with some tuning knowledge could back that up for me that would be very much appreciated as i would not mind buying a coupleof chips and having a play around to get some more power from my rides.. REgards... Chris

hehheheheheeehheheheheeeee. i will keep it strictly to computer art: note some of those 3d pro engineer prototype designs took well over one thousand hours to design!

some more cool prototype computer art designs that i have found from the net.

if you look rather closely you will see that the majority are in fact 3d graphically created computer art or futuristic designs.

other cool computer art designs: i love the bike

cool lambos, evo's, porsche designs, beeemer, spy plane! heheheheheheeeeheheee

cool porsche
