Can You Use Safc With Remapped Ecu?

[aquariuz6]

Hi,

I was curious to findout if its possible to use a SAFC on a remapped ecu?

I think it is possible. Wouldn't be just a simple plug in and tune?

I would also get the benefits because my ecu doesn't go rich and retard, it has been all removed.

Boost cut, speed limiter, rev limiter, etc

So I was interested if I could get away with running a SAFC to its benefits since the ecu was remapped before my high flow turbo and fmic was installed.

Any opinions?

Depends if your remap chip is rewritable?

If so I would think it would be much better and cheaper to get your computer rewritten again.

I don't know about being better to tune because R&R have been removed! It is a fail safe mechanism and is there for a reason!

[13thracer]

yes but rich and retard sucks

[Mr. Oizo]

SAFC doesn't rewrite the chip.

It alters the signals from the sensors and tricks the ecu

[aquariuz6]

I know SAFC doesn't rewrite the chip but it allows to tune the afrs that have already been tuned.

I can tune it to the way I want it without it going rich and retarded

if it's an safc2, i reckon you just sell it to me, cheap, and we're all happy.

[aquariuz6]

I don't understand why its so bad to have these two together?

Can anyone actually give me facts to why it wouldn't properly work and achieve the benefits?

The reason why is I have an auto tranny.

If you think about it... when you tune a car with a SAFC what is the thing that usually limits you? R & R.

But since my remapped ecu has removed the things that causes it to go R & R, wouldn't it be able to be fully tuned similar to a PowerFC?

Can anyone correct me here?

if the remap is done correctly then the car is already tuned to its potential. if you need the safc to make more power, or you make more power when you tune the safc then the remap isn't done correctly. you can have both but there's no reason to.

Hey Paul,

The reason to why I would get it tuned is because I got the ecu remapped when I didn't have the Highflow turbo and FMIC installed.

Wouldn't it be running lean or something?

I haven't been able to get it on a dyno yet because the car is running crap at the moment.

As if its struggling between low to midrange revs.

Just planning to get new spark plugs, check the coilpacks then get a compression test just to see if the engine is healthy after the turbo change.

The car struggles as if its running on 5 cylinders or something.

sell your safc and remap the ecu again, because you cant alter the timing maps with the safc, and may run into knock issues if your chasing decent power. personally i wouldnt use an SAFC for any more than 210ish kw at the wheels because its not going to give you the most out of your car you would benifit more from remapping again than just tuning the safc. as for the struggling check what your going to check, dont hold me to this but, with the high flow and fmic and your running more boost than before you may be stepping out of the current ecus map and hitting R&R.

[aquariuz6]

Hmm sorry but I was just actually thinking if it was possible to mix both together. I don't have a SAFC. I was just curious to what benefits could it bring. I guess another theory down the drain.

I was told that I wont be able to get bigger injectors, z32, cams, etc because even remapping the ecu won't support them.

Is there any other way for auto tranny's to have a pigyback ecu that would be more similar if it were manual and just have a powerfc?

[Mr. Oizo]

Cant you just get it remapped again?

[aquariuz6]

I will be getting it remapped again but the person that remapped it before told me that I was limited to modifications

[AlexCim]

then just get a pfc, they are 950$ + $400 to tune.

best bang for buck around.... a remap cant be less than 300-400$ and a SAFC2 is 400 bucks.

but he is in an auto, so driveability will drop if he goes to a PFC.

[hanyou]

ahh im gna do this as well.. cause my car already has a mines ecu in it.. and i want to get it tuned when i fit my hiflows when they arrive and put in the boost controler..

so safc and mines ecu should be ok to do that? i jus cbf getting a stock computer lol so much effort to sell stuff nowadays

[aquariuz6]

Interesting that your going to give it a go.

Atleast with the mines ecu it also has removed it from going rich and retard.

Like for example when using the safc alone with stock ecu... it goes r&r.

If possible... shouldn't this allow you to be able to attach a z32 and bigger injectors to it? Or is there more technical info onto using a setup like this?

Let us know how it goes as I am also in need of a remap once I install my Highflow turbo, z32 and 540cc injectors next year.

Cheers,

Bernard

[paulr33]

remap will allow bigger injectors but safc by itself wont.

[hanyou]

yeah thats what i thought,.. the mines ecu will remove all cuts and R&R. so it should let the safc do its thing without hassle. but yeah ill be doing this next year lol, thats only if my mines ecu hasnt got a good map for the hiflows. but ive been told the mines ecu would be good for the hiflows alone with sensible boost. so ill let you guys know.

[mad082]

the safc will let you trim up the afrs, but the mines ecu should be ok.

the safc would also allow for a z32 afm, but not injectors.
