Where is the sensor placed?

 

here's where you see a difference between Trifecta and HPT;
with HPT, you have the end tuner sitting right there, observing things such as AFR - even in the case that AFR isn't monitered by the car's ECM;
In the case of the LSJ (as I have understood it), the ECM cannot read AFR - it probably does like older GM ECM's, and looks for a target temperature reading off the O2...
At best, all we can do, is report what we're seeing to see if WOT-Tuning can determin if the tune is reacting the way they want it to.

Mark, we would need to verify that your wideband is owrking, and from what I've read here, it looks like something is not right;
You should not have a huge delay in readings... maybe you have a lose connection somewhere?

Rich up to a point is safe - where as lean can get dangerous fast - Dustin would definately know about this.
Once your wideband appears to be functioning correctly, wee need to see where your readings are on light throttle cruising, and then see where it goes to when you tromp on it - as well as how it appears to act after romping on it...

For a short time last year(?), i was running an optional tune which would suit people who want an atmospheric BOV, iirc it was called something akin to a 'Predictive Airflow' tune - I stopped running it, because I was observing afr's floating around 15.2 - which too me seemed unsafe/too lean.
I'd rather get stomped on by LSJ's, and be able to rely on my car to continue being my DD, rather than chance wrecking something...

Mark, I'm actually leaving town on thursday morning, and won't be back until monday night.
You can call me at home later if you want ot meet up, but unless your gauge appears to be reading/functioning correctly, I would advise not trusting any of it's readings.

 

It's an OTTP long tube header with both the O2 sensors side by side in the collector

 

So you can not log A/F with Trifecta? you just look at the gauge and tell him??

 

i will try to back off the ground a lil maybe i have it to tight. there is no real ******* up the install of this gauge. its equiped with plugs all you have to do is wire up the ground and the positive. the sensor is in the correct position and is in tight. all i can think of is the ground or a bad sensor.

i will call you after work jonathan however i wont have my car tonight as it will be over at geoff's. the soonest i can do a datalog session is wed eve after a funeral i have to goto.

this is correct





overall the car seems to be running good but there are afew things we need to work on, and by in no means am i panicing about the readings i had.

 

You got it. Lsj only has a narrow band. No wideband running through the ecu. So as Jon said you have to dictate to trifecta your afr for an actually decent afr. Otherwise they'll just make it safe and pour a bunch of fuel in it.

11.8 is a good dd afr that you will still make good power with. That's my recommendation to try to get the car to sit at during a 3rd gear pull.

 

Can you datalog the A/F with HP then tune differnet ratios to your likings through the rpm range like you can with an LNF?

 

With hpt pro you can yes and have a wide band that has data logging wires.

 

Ya I do

 

ok i actually think its working proper and always has. i put some thought into this and i feel its because i am catless. i just went for a drive and 5 mins later i got a accurate reading. i was at 11.8 the first time in a 3rd gear pull. then i did it again and it read 11.3. i feel with having no cat it just takes me going into wot to get a accurate reading.

 

Sounds to me that you're in the "window"

 

i think so too.

hey JD! thank you good sir everything went perfect. if you have any issue let me know or if you need anything let me know.

 

Oh ya your afr will bounce all over the place till you go wot lol

 

Mark did your old wideband ever work?

 

thanks as always for your contributions here

As dustin elluded, you would need some sort of interface between the laptop running HPT & your wideband - since the ECM cannot read this, there is absolutely NO way for LSJ guys to get this reading from their 'on board diagnostics' port.

This may be the only instance where you can say LNF > LSJ

 

I saw it (I actually helped with hte initial install), it DID work...
Well, at least it did after Steve came over, and wiggled one wire.



Made me feel stupid for getting dirty, and then proceeding to chase down all possible reasons for it not working

 

I knew that you could datalog with hp pro through a gauge I was planning on doing it with my meth but was just wondering if you can tune the A/F at each 500rpm interval or whatever like you can on the LNF. And I think Mark vs me will see who wins the LNF vs LSJ battle we both have a ported stock poweradder and technically he has more done to his can than I do

 

for maybe 1 year. i also recall it being absolutely stupid on trying to get a accurate number from.

bite your tongue, no cuss words allowed. yes blue, i do appreciate the help you always have presented. the same goes for jonathan, kevin, and **** face up north hahahaha. you know that sylver guy? without your guys help i may still be on jack stands.


i felt even more like a moron then you i am sure. as you can see i even thought that might be the issue in this case. hahahahahaha




the bottom line is i cant wait to line up with kevin again. we might need to vid that one. that way there is video proof that both cars kick ass.

 

Who wants to come record it from my (the winning car!!)

I think the whole LSJ vs LNF comes down to supercharged vs turbo it's just what you like both are great but I'll never tell Mark that because I'll always say to him LNV>LSJ oh **** did mark see this??

 

come on guys! we all know the lsjlmnop is by far the better car. hell my car has built in vibrating seats. we all know thats a win!

 

Oh wow. I just deleted what I just wrote was not even close to PG-13

 

lol not to mention they are heated!

 

That's OK I hate heated seats feels like they're warmed by farts

 

The SS/GT will decimate all, WITH about 15 Grand in parts, overnight from Wyoming.....!

 

i know right! thats perfect for a dutch oven master like myself. nice and jon now joins the pissing match hahahahaha. how is it going buddy? i have a present sitting here waiting for you.
