SAFC II or chiped ECU ??

[crazyfast]

Which one should I go for if I wanna run 14psi with 550cc and Z32 maf and fuel pump.... SAFC II or upgraded ECU like JWT..??Anyone runs 14 or 15 psi with SAFC II?? can u post all the setting?I know every car is different , but just give me a basic idea and I can do fine tune... I have SAFC II already, but think is it worth to put it on.. @@hlep??

an ecu tune would be superior. many people go with an ecu tune and then run an sfac on top of that for fine tuning.

Like he said. Many people run both, so they get all of their basic settings from the rom tune, and then additional fine tuning on top of that. But there's nothing wrong with running just a rom tune if it's a good one, like Enthalpy or JWT

Enthalpy FTW

Enthalpy and SAFC with a Wideband for minor tuning.

would it be possible to run 550's and z32 maf with just a safc2? obviously it will take alot more time to tune the fuel just right but in the end will the motor still make the power output and still run good?

ive seen it done

I ran an S-AFC II with a GT2871R, 550cc injectors, and a Z32 MAF for about a year. The only thing that I will tell you is that you NEED a wideband O2 sensor if you are going to tune it yourself. I had a PLX Wideband on my car and tuned it while driving and got an ok setup after playing around with it for a while. It wont be perfect though, I had to run rich in certain areas (in between the limited number of breakpoints the SAFC has)

Im running an AEM EMS now but if I were to do it again, I would probably just get an ECU turn from Enthalpy.

The only thing that I would tell you is that if you dont have a wideband and will have to either get a wideband or pay a dyno to tune it, the cost of the SAFCII and wideband O2 will probably be more than just sending your ecu out to Enthalpy to tune. (His tune will be way better than the SAFCII too)

for the record i do believe Enthalpy is cheaper and also is proven to make like an extra 30ponies over the JWT tune
