Greetings all,
I'm preparing for the nor-cal dyno day that Mad has set up for the 18th.
I have my chip ordered and configured for 42# injectors, 90mm MAF, 10psi boost, and I have my 255LPH fuel pump installed.

Will I be removing the FMU once my new tune (for the above items) is installed? Sal didn't have an answer for me.

Thanks

You should be able to get rid of the FMU once you install the larger (42 lb) injectors. Plus, with the other fuel upgrades that you bought, the tuner will have no problem getting your A/F right.

What is your setup?

 

correct. no FMU with 42#'s

 

Adam,
When I got my dyno tune the tuner (LaRocca) was able to do the programming without the FMU. However, he did say that it would have been easier/better if I had left it on. Perhaps you can check with the tuner you'll be using to see if he has any preferences. Good luck with it and keep us posted on the results.

 

Just so I can be completely clear.
I am planning pretty much the same upgrades.....42#, 90MM MAF, 10-12PSI. Once I get my tune on my chip and install the mods, Remove the FMU and swap the IAT to where exactly?

Also I installed the pigtail for the A/F gauge onto the O2 sensor after the CAT and Im not getting a good signal (one faint red segment light). It is an Autometer Cobalt A/F gauge, should I move it to the O2 sensor before the CAT?

 

Hey all,,

IT STARTED!!

42# injectors, 10psi pulley, 90mm MAF,,,pre-programmed SCT chip,,,,,,NO FMU!

What a PIA to put those injectors in.
