X2 with the boost referenced regulator.

I don't know if that MAP sensor is suitable...

[garyk1970]

Also, what model AEM wideband do you have...?

aem 35-8460 wideband with gage...

[garyk1970]

Are the injectors rated to flow 80 lb at 43.5 psi (3-bar)...?
\yes. my fuel pressure is high also...70 psi static...probably a return line issue

For boost you will have to run a reference hose to the FPR because in the 411 tune files the IFR does not extend into boost...
Can't you run some heavy duty fuel hose and clamp it to the FPR and MAP nipples...? yes, i can reconnect....no problem..

MAF-less, ok.

Do you have exhaust manifolds or headers...? So the NBO2 sensors are one per bank...? Does the wideband get sufficiently hot...?

drivers manifold is stock...passenger manifold is trick performance stainless cast manifold (turbo mounted on it)with NO o2 spot....the passeger o2 is in the down pipe...the wideband is in the down pipe...both are 18-30'' from turbo...

You are certainly jumping in at the deep end starting with a boosted tune.
Do you have the voltage output info for your wideband so that a calc pid can be made to correctly log the data.(if it isn't supported) All your ducks should be in a row before you start or you will end up chasing your tail & getting frustrated rather quickly.
Injector data is also one of the most important things to get correct before you start.

yes i have.. im not new to turbo charging, supercharging, fast programs, or holley fuel injection...but efilive is new to me...i know the numbers to shoot for, just now how to setup the program up to get there.....
the wideband is off.....im trying to figure out how to adjust...ive had a hard time callculation my injector data...

80 lb sure fire injectors based on 43 psi
fuel pressure is 70 psi..not sure why...i think my pump is too big for stock lines
i will connect the stock pressure regulator...ive read wherte a stock 99 silverado one will work with boost.

thanks

is there one thats better, or a good one i can install? just was lazy, choose one that was plug and play...

Does it have a serial comms port (is this how it talks to the gauge)...?

EFILive hints:
- set VE units to g*K/kPa,
- set fueling units to EQR,
- set PE sufficiently rich to be safe (and make sure it will enable),
- log GM.EQIVRATIO,
- use wideband Lambda for correcting VE and/or MAF tables (might need a calc pid for it),
- disable MAF and trims, correct VE table;
- disable VE and trims, correct MAF table;

More info, see posts #2, #4, #29, #38 in this thread: Summary Notes

hello Joe;
im using the 5v out of wb and a ground connected to A1 input on the bottom of the v2...

There is a thread on how to correct maf and calculate ve. Inside the thread shows how to setup calc pids to use analog signal and use it with eqr and lambda. I think
