I figured I would update this as I successfully flashed the EEC-V on our 2002 Mustang GT today and did not run pig rich as above . It idled stable in open loop.
I made sure all tables had the stock EEC-V starting and ending points (fuel and maf) and used the stock Offset Multi vs Pressure as HPT adds a decimal place the OEM table doesnt have and I could not get rid of it so I went with the stock table to be safe. Idle was 11.2 - 11.5 on both wide bands and stable in open loop.
I am running poorly in closed loop which brings me to the next issue. This scanner will not log any data. Nothing. We tried all day and when it does connect the scanner It will not record anything. So I am dead in the water again.
Ticket number is 170129 if any support see this.
I hope that table info helps somebody. There is a wealth of info on www.efidynotuning.com for EEC-V .
