*Closed* 20% Off Supercharger Group Buy 2nd Gen 4.0 Engine

Do you have an aftermarket fuel pump?

 

No. I installed an AFR gauge this morning. I'm at 14.6ish cruising. Its a holiday weekend and I had the wife with me so I didn't get into the throttle much. Still no issues though.

 

Here's my temporary setup. Not sure what I'll do later.

 

Speedhut is having a 20% off sale, right now.

They also have a new wideband gauge that has an integrated controller and comes with the wideband sensor.

Had I waited a bit longer I could have saved almost $400 between the 20% off and getting a pair of their widebands vs a pair of their AFR gauges plus a pair of LC2s. Too late for me, but for anyone still hunting for gauges that's a pretty good savings.

 

Maybe a dumb question but which specific afr do we need?

 

Wide Band

I posted the question for you in the gauge pod thread, @loginfailed...

What make/model gauges did you buy? (I like the look, with the Toyota logo, but they weren't immediately obvious on Speedhut's site.)

 

Ah I see, so you have to get a bung welded into the exhaust?

 

If I may answer for @loginfailed

They're the Revolution series gauges with custom logo. Basically, you select the size of gauge you want, customize it to look however you want, upload the logo you want it to have, and then place the logo where you want it to go on the gauge. Order the gauge(s) and then send SpeedHut an email with the order # in the subject line stating exactly what you want the logo to look like. Adding a logo will cost extra, but as you can see, it's well worth the minimal up charge.

 

Its best to have the bung welded before the catalytic converters. Or you can do like I did and buy one of these. Drill a hole, strap it on and go.

Yes **edit** or see @gersus's post above.

Most people go for 3-4" upstream of the driver's side catalytic converter, angled 15-30 degrees off center.

It's a piece of cake for a good exhaust shop to do and shouldn't cost more than $30. Just make sure the welds are solid because that's not a good place to suffer a leak due to shoddy workmanship.

 

One more thing. Go with a NTK or Bosch 4.9 WB sensor. 4.2 is old technology.

 

Not sure if it's the scientist or the artist in me, but I couldn't help but add my mark for posterity

 

How does the AFR gauge look at night? Is it too bright?

 

Just got done! Wow should of done this a lot sooner.

 

Whats watching your injectors duty cycle?

 

I thought if you were running one sensor only was better to go past the y pipe so your reading both sides? I know that will report .4 or so more lean. This is a project for next weekend or sooner.

 

good to hear folks are getting their installs done. rain slowed things so i didn't start until today. made it to #95, which just so happens to be 'remove crankshaft pulley bolt'. frack.

my black friday harbor freight earthquake is not getting anywhere. it may be my 1/4" air hose fed by a 10# CO2 tank lacks huevos? i had the regulator dialed up to 170 at one point.

hopefully i can get past this soon. i'm right at the part where parts start getting bolted on.
