What wideband you got? The one i got from haltech (innovative from memory) needs to be configured in the setup (Press f4), and you can set the AF vs voltage table, and the instrudtions said you need to be very particular with the wiring. But the car should start without the wideband.
Sounds like your TPS is on the wrong way, i think from memory you can change the 0% and 100% voltage values. ie the base map might be wrong, not the wiring. Having said that, i swapped a E11 out for a PFC on the weekend, and needed to change the TPS wiring to get the PFC to work, so the Haltech might need the wiring chaged from the factory settings.
Factory base timing is 15deg for RB20-25 from mem, and 20deg for RB26
