MAFT/SAFC Tuning 850cc

[Dave_Hash]

Are you able to tune 850cc injectors with a maf-t set to the default 850cc setup and a SAFC to do fine tuning? If not what is the biggest injectors that I could use with the maf-t and SAFC together?

I believe 650's are the largest that people can reliably tune.

If you have 850's, I would suggest getting a keydiver chip or dsmlink (if you have an eprom ECU of course)

Agreed dont even try to tune those with just a maft or safc.

I want to know if I can tune the 850cc with the maft and the safc together

No they both work about the same.

Let's just put it this way. Would you be able to tune? yes you would. Would it be a good tune? No. Would you be getting the most out of your setup? No.

Would you really wanna take the risk of running too rich or too lean and possibly causing engine damage? Only you can answer that.

Timing will be so greatly increased you most likely would not get rid of knock no madder how much fuel you through at it.

If you are planning on spendng all that money on these parts:

I think It's only common sense to spend the extra cash on a tuing device other than a safc.

Thanks for the replys.

The only reason that I was even considering using 850cc injectors was because someone that thinks they know everything about DSMs said that I must use them with the t3/t04e or I would hit fuel cut. I felt that the 650cc would be fine for now and that is what I wanted to use. I plan on getting the 650cc until I get my 6 bolt built and DSMLink in.

Yah i also have to agree with most of the people in this post. I am running 680cc on the safc II and maft Gen 1 3" gm. I am having quite a time getting a good tune with even these size of injectors. I'm considering upgrading to the Gen 2 MAFT and getting a wideband and test out the wideband tracking on the new MAFT.

Hitting fuel cut has nothing to do with what injectors you're using.

T3/T4 doesn't really say anything about a turbo so we can't really answer you there on your injector requirements.

Correct and correct.
