Tuning SAFC2
Hello everyone...I bought an fc not too long ago...and it undergo some modification and as all beginner I need help...
I have wired Safc2 on my 86fc turbo and programed 5in 5out 4cycl with the up arrows. I want to tuned this ecu piggy back ie:the value of all the 12 Ne points's, TH points, and the lo-throttle and hi-throttle values. Can anyone help me please??
Mod includes: 4x720cc injectors, walbro fuel pump (255lph), 3" pipe and everthing else pretty much stock (for now anyways)
anyhelp is greatly appriciated...

feel slower
I have tuned my safc2 but there are things that bother me. It feel that my rx is slower than stock. before I install safc and injectors...I ran a 6psi boost on it (and it ran good) but now after 4x720cc injectors and safc2....my boost drop to 5psi and it feel that my car ran slower than before (may be because lower boost??)
The guy (mech) told me I needed a good spark plugs and wires....but I replace them with denso plugs (they're $8 a piece) and a split-fire 7mm wires....so I dont understand why my car feel run slower...
any help??

OBEY YOUR MAZDA
SAFC = Super Air Flow Converter, it tricks the ecu to generate different output to the injectors.
FPR = Fuel Pressure Regulator, is used to alter fuelpressure if you have installed an aftermarket fuelpump.
Id say that 250rwhp is about as far as you can go on the stock Hitatchi turbocfharger, not exactly sure though...

I have a 255lph walbro fuel pump (I think this is one of the most common aftermarket fuel pump used in FC)...Do you think I need one of this??
I heard so much talking about porting wastegate....but if I only running boost for 12psi... I dont need a ported wastegate..right?? (or do I?)
btw thanks alot for everyone helps so far

Without andjusting the turbo pressure you'll never be able to gain 100bhp by just adjusting the fuel delivery. You need to get a boost controller (mechanical or electronic).
Then get it on a dyno and hook up a wideband lambda sensor. Add boost, but make sure your lambda ratings don't go too high. 11'ish would be max.
There's a couple similar threads in this forum. Have a red through and you'll find some more interesting info.

I have a turbo boost controller...from "turboxs"...and I brought it to dyno...and the mech told me...my plug isnt good enough (only for 180rwhp). but this plug is denso (and I tought they have a high heat range....after all they cost about $8usd a piece)
I have spent about $2000cdn...and ma car only incresed 25hp more from stock...therefore I tought I did something wrong...or missed tuned my SAFC.
thanks for your help.

Have a look at the links posted in this thread for more info on setting up the SAFC2

Oh and I paid much more for my plugs ... (NGK BUR9EQ if I'm not mistaken)

These aren't racing plugs I'm using. They're what Mazda prescribes for trailing (I believe) plugs. I use them both in trailing and leading. The iridiums are a grade above, but I've not heard of significant gains or strong need for them in modestly powered rotaries (300ish at the wheels).

You can upgrade to an FD alternator. This will make it for your system easier to cope with all the electrics. You can also add an aftermarket CDI system.

There's no relation whatsoever. The SAFC II works totally independent from the turbo.
Neither should stop working after upgrading the turbo system. The engine will die only from improper care and/or improper tuning.

I have an SAFCII, AVCR, 3" downpipe, Walbro fuel pump, but no upgraded turbo (yet). Still need to tune the lot, but right now I'm fabbing brackets for my e-fan. I'll probably start fiddling with the electronics early next year.
