DBW to DBC No TPS or IAC counts (first start video)

[1970ss8.1]

I Switched from the stock 78mm DBW TB to a 102mm DBC TB. I have the drivers in the P59 ECU. I can not get the scanner to read any TPS or IAC at all. I just fired the engine for the first time and the IAC whistles loud. I opened the throttle blade and it got quieter. I don't know why but I cant scan and of the DBC stuff. Also I put in 42LB marine injectors and used the data that is attached. Please help.

never done a DBW to DBC swap but,i would assume you need to populate the tune with the proper IAC info for that TB

there should be some express van P59 dbc tunes you can compare to. IAC info needs populated, and make sure you set ETC to 0 in system options. I'm not on a PC I can look at the tune on currently so not sure if that's been done or not, but its commonly missed.

I have a 5.3 DBC tune can I use the data from that or do I need to find data for a 102mmTB

[charcoal03silvy]

there is not data for dbc 102. Just look at a factory DBC file and it'll have some of the IAC stuff populated. Again make sure you've set ETC to 0.

My ETC is set to 0. I?ll try to put in data from the 5.3 tune.
