        As you probaly know trying to tune the SAFC without a wideband will be pretty crude. Have you tried others SAFC maps with similar setups as a starting point?

          it dose have a wideband and no fuel maps are posted anywhere its a safc2 with map sensor for engine load not to sure what the bp55 ecu came in

            someone posted maps for a safc setup just like that ... like 2 years ago. it should be on here somewhere though.

            if you sold the BP55 and the SAFC youd have nearly enough cash to buy a megasquirt.....

                no it is either a euro spec GTX ecu or an australian ford laser tx3 ecu. one is bp55 one is bp58 i always get them mixed up. the euro gtx ecu is the same as a bp26 but revlimits at 6500. the laser ecu doesnt make as much power, its tuned for lower octane fuel.

                    i was thinking gtr ecu the injectors would match it but not sure if turbo is close in size or not

                      a gtr ecu would work pretty well, i know where you can get one too.

                            With the gtr ecu there is NO boost cut, so you just need to watch your AFR if you are running high boost... it will just max out the injectors and you'll run lean if you boost too high.

                            PMing you
