In the archives it states that the VE vs Map table is from 0x37f through 0x3c6 a 8x9 table. there is another table from 0x32b through 0x37b that has almost constant values through load range any idea what this table is? -- Jason Weir 88 Wrangler - 258 Chevy TBI Fayetteville, North Carolina http://home.att.net/~jweir mailto:jweir at worldnet.att.net
