Rb25Det Serious Spitting During Acceleration Tuning Or Something Else?

[EJT33]

hey everyone

Does anyone know why my car could be kicking back and like a loud noise coming from the exhaust it just started recently so ive changed all plugs the coil pack and done a full service thinking it could be the oil which I was told but made no sense as I only run motul 300v chrono it usually happens on boost but not all the time im currently have a profec b controller and a apexi afc neo( I know its not as good as a power fc)

I have larger injectors 600c upgraded afm z32 larger fuel pump and fuel pressure regulator it seems like the car is running really rich or could it be another issue that I haven't figured out.

If anyone knows the basics of tuning an afc neo please let me know as well as I cant get a booking for a tune till mid june.

Sorry if this Is a stupid question but does + on the afc mean your increasing fuel or the air intake thanks

I can't think how it could be the oil unless having none has caused a failure.

Definitely sounds tune related. The combination you have described plus AFC Neo = monkey purple dishwasher moon dog wonder special long time. ie = it does not make sense and will not work properly.

Do not drive the car until it gets a proper tune.

ok wont do thanks so I take it the neo isn't a good choice with all those mods will I see a difference with a power fc and where is the best place in perth to tune was thinking either hyperdrive or ovaboost anyone have reviews on either of these I use to get hyperdrive to do a lot of work on my silvia and they were pretty good

Put a wideband on it and figure it out, with those mods I would use a standalone. I find SAFCs only good on stockish cars to tidy up the AF

[EJT33]

yeah didn't realise the safc were really restricted to what they can do will be upgrading to a power fc and give it a full tune which should solve the problem and give me the extra power that I seem to missing with it

[Dose Pipe Sutututu]

if it comes cheap then get one, if not there are plenty of newer ECUs out there.. PowerFCs are dated.

thanks for the advice
