That'd be a sweet setup, but I heard the auto box that comes in those isn't really too power savvy

All this coming from a guy who has a nissan sentra.... J/k LOL Well I have both in my hands... I have since decided to go with the AEM. And not just an access port bro. Its street tuner. I have had some good results with it on my old engine. My concern was in getting the car inspected. I am sure its going to be hard with the AEM. bon

Its innaccuracies are not from being a bad/cheap sensor, it's from the pressure in the uppipe, which will be just as...

My comment about metered air was if it is not recirced to the intake. I don't think we are being anal, Subaru didn't bleed the OEM system (with a restrictor pill I might add, not just a 1/8 inch line) to atm, they recirc'd it!

Cool. I'm going to cap off the intake return port on my grimmspeed bcs and we'll see how it goes.

There's a "MAF sensor scaling" table in the ECU that would need to be adjusted to match the new MAF housing. If you can find someone with the same one, and the same injectors, you could borrow their MAF scaling table and probably be pretty close. But you'd want to us a wideband O2 sensor to verify your AFRs though, just in case.
None of those will gain you measurable power though. I ...

i'm getting the p0245 boost solenoid A low CEL. anyone know whats up? is it
wired wrong? is the resistor broken?

I have not tuned E85 on boost, but what I see is power should fall off if
you go richer then 7:1. Anywhere from 7 - 8.5:1 is pretty good on E85,
which equates to .71-.85ish Lambda.
if your wideband doesn't have a E85 setting, just use lambda so you don't
confuse yourself (or us LOL).
Anyone run that rich on E85? I do know Alky is more forgiving of that then
gasoline.....

not that i recommend it, but i drove around on a full catless system for quite a while on a stock tune. even after i tuned the car i still had the stock delay set and it ran great. once i changed the delay to 0 it felt a little more responsive and ran better AFR's. it really wasnt a huge difference though. i wouldnt really worry too much about it especially if youre just driving to your tuner.

the voltage response to a given O2 level would have to be the same as th stock one. Or the stock ECU would have to be reprogrammed for the new voltage range, I dunno if this is possible.
IMO its not worth it unless you were going standalone. The stock powertrain has spent enough time on FHI's dyno's to handle itself. Plus the O2 sensor only plays a role in anything in closed loop ...

check and make sure you don't have the wrong nipples connected on the g MBCs.
at rest, with the car off, you should be able to blow from one connected nipple to the other. the car energizes the solenoid to raise boost. this will stop the flow through the solenoid.
when troubleshooting you can also disconnect the BCS entirely to make sure that your MBC plumbing is proper.
finally make ...
