I'm going to use the $6E calibration, so I need a 27C128, right? When I go to digikey.com, what's the exact chip I need? There are selections for serial/parallel, voltage, etc. I thought I would go ahead and order the chips there along with the eraser.

'87 Formula WS6 - ZZ4 Crate TPI, SDPC ported heads, LT4 hot cam, 1.6RR, Accel runners, Accel lower, ported plenum, Edelbrock 58mm TB, Crane Fireball ignition, SLP cold air, SLP headers, !cat, Summit exhaust cutout, Walbro 255, Koni yellows, aftermarket panhard & LCA's.

 

Hunt around and get some "pulls", ie used ones, they go from 1.50 to 1.75. That way they are disposable, and runing them doesn't hurt, like $4 a peice new ones do

 

So as long as it says 27C128 and it's an eprom I can use it, right? I guess I'm thinking there is more to it than that because of all the different part #'s at a supplier's website.

 

I just bought 10 27128a chips on ebay for 3.80 & 5.00 shipping. Also look there for an eraser too. Bought mine for 20.00.
