ADM FPCM + Livernois twin pumps? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

LS3 SS · 10-01-2014, 08:45 PM

Forgive my ignorance if I either didn't read the information correctly, or believed it without doing proper research, but :

I remember reading a while back that you can't use a reprogrammed FPCM with twin pumps. I'm on the stock FPCM with Livernois twin pumps and ID850s and have FP drop, and I'm trying to solve this issue the most cost effective and least painful way. I've tossed around the idea of a BAP, and a bigger feed line. But can anyone confirm that you can or can't use the ADM FPCM with a twin pump system, and if so, why/why not?

I ran the ADM module with my Livernois Twin for a day or two, popped some FPCM codes at the top of 3rd and posted about it. Andy ripped me a new one for trying it.

I think the current draw of the twins is too much for the module to carry.

Put the stock FPCM back in with the twin and no codes.

Still too small for my setup. Squash this winter for me on the corn.

The Adm twin pump kit uses the same twin pumps and it comes with a new fpcm you just have to pin it. Its not the same fpcm for the zl1 pump I don't believe if that's what you were trying to use.

Yes it was the zl1 fpcm from adm that I tried.

So what exactly would I need to do to use a reprogrammed FPCM with my setup? Or should I go a different route?

And so you're still here lol. So im turning 80k on the stock motor and with the corn mix lol

Was looking at super chargers +e85 but concerned about what else id need to do.

Still hoping for the Squash returnless to be released. I can get by with the twins, pressure drop is consistent and the tune compensates for it. Injectors are large enough (95 lb/hr) that I'm still under 80% IDC at 10 psi boost.

atxcamaross · 10-03-2014, 06:36 AM

I have id850 s and 9 psi on e85 made 714 on a mustang dyno. My injectors are about maxed out but tuner said my fuel pressure was good. I have the Adm twin pump setup that replaces the stock fpcm

On bigger builds we just throw away the FPCM and run twins with a return line. Pretty simple to do and no worrying. Holds a lot more too with a return line up front compared to at the tank.

2012LS3VERT · 10-03-2014, 08:23 AM

Yeah, I'm hoping for the Squash (or anybody) returnless as well. I want to run the flex fuel sensor as well, I just want to do it all at once, so i'll wait because I have enough fuel pump for 93.

mylftft · 10-03-2014, 03:16 PM

Setting up a return line really isn't that big of a deal.

Okay, but what about trans, suspension, tires.... anything needed there??

Iam Broke · 10-04-2014, 01:28 PM

I added BMR spherical bearing trailing arms, sub frame connectors, & tunnel brace. Still on the stock Pirelli's so my right foot does the tq management, not the tune. No wheel hop tho. ~650 whp +/- on the stock drivetrain and clutch. Never been on a dyno but 3.6 sec 60-100mph logged in HPT Scanner.

I thought you were on the stock dt.... you must do a really good job at tq management below 25 mph lol Those stock tires are likely your safety net for the dt from being damaged on the low end (btw i heard stock clutch slips after 550hp again all that power being dumped on the low end)

I really could use like 10 psi of recirculating standby boost at idle and like 4-6psi above 2800 rpm on the corn lol and no mods to dt lol and id only be willing to pay 800 to 1500 for it
