I'm simply saying it's not the same.

i have tried this with my plx device and it works great i havent gotten any cels yet

boost, a/f, egt

battleversiontc · 12-03-2008, 11:00 PM

why everbody gets the added hole for the wideband is so it plugs into the gauge and uses it as a seperate monitoring system while the factory ecu reads off the factory installed unit to apply fuel/air more properly and by the way bosch makes a wideband sensor for a replacement for the yaris

beginner question.....besides "boost" lol what does a boost guage pull its reading from? Some line i would assume but which?

whooppee777 · 12-04-2008, 05:38 PM

it reads the pressure levels from a vacuum line off of the intake manifold.

at3GG · 12-04-2008, 09:34 PM

is that line there stock or added when a boost guage is added?

LtNoogie · 12-04-2008, 09:37 PM

I'll let you know in a week or so. I just purchased an Autometer vacuum/boost gauge from Garm. I have to see what parts came with the Blitz kit to connect to the new intake manifold. Right now, the hole is pugged with an Allen screw.

LtNoogie · 03-15-2009, 01:17 AM

Ok, it's taken over four months since I asked the original question. Here's a video of my vacuum/boost gauge and wideband a/f gauge. Sorry for the shaky picture but my camera mount shakes and I had to zoom to get the gauges to fill the screen. The oil pressure gauge has not been connected to the sender unit yet.

I'll be cross-posting the same video in another thread so you don't want to watch it twice.

That thing is lean under boost. You need a tune.

LtNoogie · 03-16-2009, 01:08 PM

The provided Blitz fuel controller is a black box and not adjustable. Would my only options be larger injectors? Wouldn't that make me run too rich under NA operation?

No, don't do that. Getting bigger injectors will probably just make the car slower. See my response in your lean condition thread.

My theory is that the black box retards the timing making the OVERALL tune safe. You would need to datalog to see for sure, or monitor EGT.

If you are going to spend money, spend it on some way to tune the car. I think you could easily pick up 15-20 HP from more agressive timing, and richer AFR under boost.

Again, you don't need bigger injectors.

Hmmm, 15-20 more HP. What would I do with that?

Win.

I thought you were going to get TC injectors?

We need to stop meeting in two threads like this.

largeorangefont · 03-16-2009, 01:51 PM

agreed. I'm done here.

largeorangefont · 03-16-2009, 01:34 PM

Word on the street, and what really works are usually 2 different things.

If he can find a piggyback, I will tune it for him.
