what standalone???

[ttshovel]

okay so the car is currently at the shop getting caged and having the turbo setup built. turbo is a gt5594. I'm shooting for the 1100-1200whp range

the guy building the turbo setup was talking about running the second bank of cylinders richer than the first due to the added heat of the downpipe. the stock pcm does not allow individual cylinder enrichment...

so the 3 standalone controllers I'm looking at are the ms3 pro, aem infinity 5, and holley dominator. anyone have any real world experience with these 3? not looking to spend 3-4k like I would with pro efi.

Use whatever your tuner has good experience with and can give you the best results, and that you can get good support for when needed.

There's no point having any system...the best system ever...if you, or nobody local to you hasnt a clue what to do with it.

And all in you're likely to spend that sort of money anyway by the time it's bought, installed, wired up, tuned etc etc.

Also factor in how you're going to install it as no doubt the original ecu controls or is integrated with many car functions, so for all these to work you will likely need to piggyback the install leaving the OEM ecu in place and running too.

Obviously if it's an all out race car, then you can maybe forego some of those considerations

Thanks for the feedback! I was unaware of the above but after more research. I will most likely be using the aem infinity 5 series ecu and a boomslang harness. I've emailed them to get more info to make sure that the factory ecm stays in place for dash/obd function

if I wasn't concerned with cost then I'd be using ms3 pro and a racepak dash. eliminating pretty much all factory wiring

Be sure to have someone who knows that system well.

I know their old stuff was complicated as **** to use, and TBH I've heard equally similar reports about the infinity.
it is quite capable...but unless someone can make it work for you, it could turn into a nightmare.

Tuner and support is first and foremost with any system.

my tuner is aem certified. I spoke with him yesterday to verify before even considering it. the built in boost control and all the fail safes would be nice

[stevieturbo]

Should be all good then.

I just put a holley dominator in my Pontiac g8.... have everything piggybacked on ecm and bcm... dash doesnt display only due to I wanted the holley dash so all is good. There are some tricks to get alternator working and stuff but got mine all figured out... holley dominator is a great system.. love it so far

[stevieturbo]

The OEM ecu should still control things like the alternator on a piggyback install.

[ttshovel]

I'm really wanting to use ms3 pro so I've been leaning towards this and using the racepak dash.

my only concern is leaving the bcm I'm place for everything else. will abs, interior/exterior lights, turn signal,power locks and all that still work?

[BiggFoot]

Man it sounds like you are about to crank out one mean machine! All this electronic stuff sounds complicated but if it will safeguard your engine then why not?

What block are you running and what is your target psi for the 1100-1200 hp?

If you do it right, then there is no reason all normal functions shouldnt work.

Only add in the standalone ecu to control the functions you need it to control. Everything else will remain as GM intended.
