Dont bump your posts.

Im pretty sure you cant use a MAFT to tune for 750 injectors. Your going to need a DSMlink or a chip for your ECU with a SAFC.

I have read of guys doing it, so I know it can be tuned. Im not saying that its the best way to tune it but I would think I could get closer then 10to1 air fuel. If not do you think a fuel presser regulater could get me closer.

are you running a 255 with no regualtor? if so yeah. if thats what your doing you've got alot more fuel pressure then you should. im running a maft i would say get a safc2 my injector size gets dialed in with the maft and fine tuned with the safc2

I would defientely suggest a different type of tuning apparatus like a SAFC or DSMLink, you can tune with a MAF-T but it will be inaccurate and will never yield a great tune

Im not sure what year dsm you have sooo

1g 750cc baseline: BASE dial on 2, AUX dial on 2
2g 750cc baseline: BASE dial on 2, AUX dial on 6

Also make sure your DIP switches are set properly (those are the 4 tiny switches in the tiny red square.)

Also remember, the translator does the same thing as a safc, so when you get up in injector size, you may run into timing issues.

The MAFT is not something I would personally use for tuning. Simply means to an end, that end being using something other than the stock MAF.

I highly recommend DSMLink, makes tuning a lot easier.

Fixed runs perfect now. Was one of the switches. Thanks for the help. Go Cowboys.
