3.4L supercharger

Welcome to the rabbit hole.

 

This is the xgauge coding you need for the scanguage to get long and short trim value

 

Makes me miss just using the Torque App on my phone with the OBDII connector...all that info just popped up on the app without having to plug in a bunch of crap lol.

But the Scangauge is nice because it's always on and don't have to rely on my phone and draining the battery.

 

I agree, it actually should already be programmed in there but I guess there are so many different settings,
Yup the info is there all the time if you want and can be cycled out for timing or something else.
But once it’s program in it stays there even if the battery is disconnected

 

Thanks! Ill try after "work" today. However, I'm not sure it will work with my '02. It uses ISO protocol and it wont even spit out MAP readings. It only spits out MAF.

 

The scanguage doesn’t show MAP or MAF info that I’m aware of,

The program numbers shown before has to be programmed into the scanguage, xgauge, to work to shown the long and short term trims for the 3.4 motor

 

It supposedly shows MAF.

I got this from Mfr this morning:

We do have one XGauge code for Toyotas that use the ISO mode. Please try
the following code and let me know if it reports.

Mass Air Flow
TXD: 686AF10110
RXF: 044145100000
RXD: 2810
MTH: 000100010000
NAM: MAF

 

Mmmm, dont know what that one is or it’s used for?
Air speed? Amount of air going through?

There are some useless programs that don’t really work all that well on the scanguage I do know,
MPG is one that’s not correct,
Rear wheel horse power is not correct

 

I could be wrong but I think an MAF reading shows you the g/s (grams per second) reading from the MAF sensor, to which there is a normal vs abnormal threshold you could use to troubleshoot the MAF

edit - from the google

"With the engine at idle, the MAF's PID value should read anywhere from 2 to 7 grams/second (g/s) at idle and rise to between 15 to 25 g/s at 2500 rpm, depending on engine size. Most manufacturers provide specifications for air flow at idle; some will provide specifications at several engine speeds."

 

This is a long shot, BUT there are plenty of fake DENSO plugs on the market these days including the IK20 and IK 22 plugs.
So hopefully your are ok depending where you got them from

 

Hey guys I’ve got some questions that I’m running into while just installing my supercharger yesterday, I’ve got 100 miles on it since it was installed
When I drove the truck for the first time it was sputtering and almost bogging out, I had a 60 mile drive home and I could feel it running better and better, allowing me to give more throttle and not sputter out, now 100 miles in and I can’t seem to give it the full juice she so badly wants, i rum seafoam thru every place on my truck that I can because I’ve seen it do magic on the throttle body when cleaning
I did not clean my injectors, I have the IK22 plugs but got antsy so I just bolted the sucker up and forgot to throw them in, they will go in ASAP, I don’t think that has anything to do with this because on 91 I have no ping, I was throwing lean codes but now it’s a hard CEL and I sold my other truck and left my scanner in it, I do have the D shaped throttle body gasket in there and I haven’t put the O shaped one in there because just now reading up to find out it’s the wrong one, supercharger runs great and I’ve got brand new belts, it’s got 100k on it since brand new and I haven’t taken it apart, would worn bearings or rotor pack cause the stutter, when I give it gas I have to very very slightly ease into it or it sputters out, I have a 7th kit from URD and I know I need to read my AFRs I’m just trying to figure out if anyone knows what’s going on, my truck is a 2000 3.4 5 speed with 234k and fresh TB/WP, any questions for me please ask, im desperate to get this truck dialed in the right way

 

It can take up to 500 miles for THE ECU to be completely relearn for the supercharger and will run like shit till then,
There will be a night and day difference when it’s finished, not a slow gradual difference

 

Stoopid question:

Is Short trim and Long trim the same as Narrow band and Wide band? Are they ratios?

 

Nope.

Ahhhhh. Ok. Still useful numbers.

 

Fuel trim numbers are actually great to have because they will show you a problem before it actually becomes a bigger problem later.
You can monitor the health of your engine this way

 

So..

My Short trim is 0 +/- at all RPMs

My Long trim is +16 +/- at all RPMs

 

I guess I gotta go chase a vacuum leak. It's not an unreasonable assumption. Even though everything is hooked up correctly, this rig has 200k miles and doing the SC install moves a lot of old, dry hoses around.

 

Question has any one used the URD performance calibration unit to get rid of ping. No 7th no injector replacement.

 

It might be easier to just replace all the vacuum hoses, check pcv valve too and hose to the driver valve cover,
Again ANY vacuum leak is going to be a problem for a superchargers performance
