Mass air meter sizes
 

Is there any bigger mass air meters out there thena 75mm calibrated for 24# injectors that I can use on my 90gt?

You might consider using a 90mm Lightning-style meter.

C&L has a 90mm maf housing. Check out www.cnlperformance.com

You will need a harness adapter to run a lightning meter.

the Lightning mass air is calibrated for what size injectors? i have the ford plug for it, but which wires do i have to cut/connect/transplant to install it in a 90 5oh?

It comes calibrated for 42 pounders.

what about the harness adapter or plug ?

Re: Mass air meter sizes
 

You can run an 80mm from C&L and order the correct sample tube for the 24lb injectors as well. You won't need to change th harness either. good luck.

You'lll use pins B, C, D & E but the LMAF is reversed from the EEC-IV plugs. Meaning that E matches to 1, D to 2, C to 3 and B to 4. The outer two pins of the LMAF aren't used for the EEC-IV.

Thanks Jeff, i was leaning towards the lightning because my new motor is a 347 with 30s. im just not sure about the 75 tb or to get an 80. btw, i will be in touch to schedule a dyno tune session as soon as all this is completed. i do have a series 3 anderson on the car too.
