i just purchased a vortech v2 kit for my revup g35 and i have a few unanswered questions before install.

the kit im getting comes with 380cc injectors, if i install a walbro 255l pump, can i bypass using the fmu that comes with the kit and just tune with the unichip?

what kind of widebands are people using for tuning?

i searched and it seems noone makes a pillar pod for a sedan, i would just have to make a custom one, correct?

when tuning with unichip, did you make a new map, or take the 91 octane map and tweak that?

any inputs are greatly appreciated

I have all of the awnsers you need when it comes to vortech. I only had to look on the first page of the forced induction section. follow this link.

i already read that thread over and over, most of the info is for a non rev or using the ssbox

rich: you think the 380cc injectors without the FMU boosting pressure will be enough for his system? test pipes, full exhaust and 3.12 pulley is what he said he is running. I would think that the 380's would be maxed even with the FMU boosting the pressures up.

aem wideband is useless for tuning unless you have a utec piggyback. It doesn't come with software to log your wideband data. You have to be able to log if you're going to use the wideband to tune. Using it for just a gauge to view then it's a great gauge.

i use innovate. innovate and zeotronix both have logging capability.

I was thinking the same thing about the injectors, 440s minimum

ya, to run them straight with no FMU I think it would be a good idea.

I guess the innovative also logs rpm and boost as well?

YOu can capture AEM data using the serial port and quick drop into excel will convert voltage to actual AFR. but none of that is useful like you said unless it correlates to rpm, boost etc.

i'd never run 380cc injectors, but I was just answering his questions. 600cc is what I'd use as that will give all the head room needed for a stock block.

so 380cc is a no go? im just running the full kit, using the oem tune from the unichip. whenever i do get it tuned, i would definately step up my injectors, but i dont want to push it out of the box.

if you are using the full kit and the unichip, then do not change a thing.

add the LMA-3 and that has the boost and rpm then the software logs it all together. AEM doesn't have anything to put boost, rpm, and wideband together unless you use a utec and use the logging on the utec.



yep, what he said which means keeping the FMU. The FMU is important to bump up fuel pressure when under boost in order to supply enough fuel. So either use the WHOLE stock kit or you'll have to upgrade your injectors.

3.12 pulley is the stock pulley on a rev-up kit correct?..i say the injectors and pump will be just fine

i dont see why fmu would not be used though anyway to boost fuel pressure

FMU's were used in the 1980-90s and they are old technology so boosting fuel pressure is a crude way to go about getting the fuel that you need. I'm sure it would be fine but that's just my opinion. I'm sot sure about how a unichip and how large of injectors it can scale so if that's a limiting factor then I guess you gotta do what you need to do to make it work. The best way to go about it would be 600s and a utec along with a good tune which it sounds like you will be going to down the road.

just get the largest high impedance injectors you can afford. Thats the one thing I wish i would have done because Ive changed injectors about 4 times now

600cc injectors get Osiris and tune it and your good to go

something i thought of, and its prolly a stupid idea. but has anyone tried to tune using the factory wideband o2 sensors?

yes, i think people do it to a certain degree. They aren't quite as accurate but i think you can get an ok tune out of it. You definitely shouldn't use them to tune it to the edge but keeping it on the safe side i would think they work fine.

You can use Cipher (from uprev) to log factory wideband.
