Faster the better, but doesn't really matter

[Wulfgang]

Haha, $3 for the chip and $6 for shipping!!! And he's probably just going to put it in an envelope and mail it to you.

Speed apparently does matter: http://cherrypicker.tripod.com/id10.html

You can pick up those chips anywhere; they are about $1.20 for the 70 ns versions at Digikey.

If that's all you need to buy, let me know. I'm putting a Newark order in probably this weekend and can get your chip for you so you don't have to pay all of that shipping.

how do u know what to program onto it? Do yall trade programmings for these chips?

[goofynick6]

Yeah, I knew it had to be at least as fast as the ecu processor, which those ebay chips were. Not saying they were the best deal, but was an easy alternative to mining thru the digikey website and picking out a specific chip.

Would one of you guys be interested in reprogramming my ECU??? I wanna add a Q45 MAF. I already have my ECU reprogrammed but it is for the stock MAF.

I too am interested in getting my ecu chipped.

I got my 300zx ecu socketed locally and put in a chip I bought from Ash. Its quite nice.

I could have the same local guy socket my rb20det ecu if someone can get me a decent tune

I can be reached via AIM at "Vkoslak"or if you have to use email "[email protected]"

heh Blacksburg VA, my brother went to school there. I'm actually driving to Bristol VA later this week.
