sn95 maf with 24lb injectors in foxbody

[Calico Cobra]

Hi, i have a 91 lx and i put a sn95 maf on a few months ago. I'm about to upgrade to explorer intake/gt-40 heads/1.7 rockers/e-303 cam. Just curious as to wheter anyone's running the sn95 maf w/24 inj in a fox without a tune.

thanks.

The MAF has to be calibrated to the injectors. What size inj's r u using rite now?

NO
and for good reason... as it won't work....

A Ford MAF meter is calibrated to an ecu.
An aftermarket MAF meter is calibrated to an injector size AND an ecu.

You will need to get an aftermarket MAF meter when you change to 24's.
OR
Get a TwEECer (or other custom tuning package)
OR
Convert to X3Z and use a 93 Cobra MAF.

sorry to pull this thread from the dead, but would a 94-95 cobra ecu work with a fox? i have the sn95 maf and 24lb injectors, trying to find a matching combo.

The sn95 ecu would require some pin moving.

The 93 Cobra ecu would plug right in.........

You really don't need those injectors for the mods you mentioned. The 19s will be fine with the smaller mods you mentioned unless you left something out.

Do your mods, leave the 19s on there and use the SN-95 meter.

For clarification....
You would need the 93 Cobra MAF as well.......
