1995 Bronco tuning help

Unread postby 1967-mustang » Tue Jul 23, 2019 10:46 am

I have recently replaced and upgraded the engine in my 95 bronco. Went from the stock 351 to a 408. I used a tweecer to tune the ECC. I have the truck driveable now. I have errored too rich in the tune. This is the first engine I have attempted to tune. My ECC is showing codes 173 (Heated oxygen sensor (H02S), bank 1 mixture rich) and 177 (Heated oxygen sensor (H02S), bank 2 mixture rich). My goal would be to get the check engine light off and fine tune the performance of the engine. I have uploaded the current CalCon tune file and two data logs.
Engine specks are as follows.
351W block
stroked to 408 CI All forged internals KB pistons
AFR 185 heads
Comp Cams XE270HR
Howard's Hydraulic Roller lifters
Scorpion Roller Rockers 1.6
BBK Performance 3501 Twin 56mm Throttle Body
Edelbrock 3881 intake
Quantum 255LPH Fuel Pump
Accell 36LB injectors
fuel pressure set to 60 PSI

Thanks in advance.

long term fuel trims at .8 you need to remove 20% fuel at idle

i dont tune tweecers.

If your injectors are fine your better off and cheaper to just put a qh on it and tune that.
