____________________________________________________________________________________________

TBI CHIPs Burnt a chip I have ran for a while BUT I am now going to do this tune myself.

I have purchased:

APU1 AUTOPROM USB PACKAGE

G1 Adapter, ZIFF SOCKETS, HDR1 adapter

I plan to read the stock chip and my TBI Chip and see whats actually different ( just curious )

ECM is 16197427

MEMCAL is BMHM

I think the correct mask is $31

I have loaded the BIN, XDF, and ADX into Tuner PRO RT and I can data log.

I need to remove the EGR from the tune as my intake has no provision for EGR and they do not make a TBI intake for the 94-95 454.

I am going to need all the help and suggestions you can come up with.
