Hey Brian, remember me saying it almost sounded like you were running in open loop and that it seems like an awful lot of timing?Two things I do see. You do not have enable closed loop checked in the software. You also appear to have quite a bit of initial timing in the ECU, I was running 12-13 degreees at low rpm.
I am not an expert just noticing difference from your tune and mine.
I don't know anything about that system...like if you have an IAC for example, it's not gonna do anything in open loop. In a throttle body setup, in open loop, you need to set the idle stop to allow enough air in. In closed loop, it will adjust to allow more or less air in given the parameters you program.My timing light shows 12-15 btdc.
He's trying to tune in open loop so he can reduce and add fuel in specific cylinders.
I called "the guy" who I am going to see next Wed and explained very briefly the problems "we" are having and he responded with several things the guy I"m working with isn't doing. I basically wanted to tell him that it's not running pretty much at all and that if I showed up next Wed if he'd have enough time to get it dialed in and he said- yeah.
I'll drive it around the field and take IR readings every couple minutes just to be safe. I want to make sure the trans and engine are talking to each other so when I take it to the tuner/dyno guy we can test it and run it.
Exactly.I don't know anything about that system...like if you have an IAC for example, it's not gonna do anything in open loop.

No idea about your tuning process/problems. Just hijacking this to say great shots of the Northern Lights/Auroras. Since we could see them in north Mississippi, did that make them SOUTHERN Lights?Exactly.
I need this to be running within 7 days so I am checking to make sure the tps & rpm for the trans is working with the TermX so it can be put thru its packs next Wed.
He figures I'll lose at least 30% from crank to dyno. I'm figuring 33%
To my knowledge, and I’ll be 70 in September, this is the first time I’ve known of them being visible this far south. It may just be that it’s not been publicized as much. The only way we knew about it was people in the area posting on FaceCrack. Well, that and seeing the alert on WeatherBug about the geo-magnetic event in Gervais OR where our son is. Fairly excited to have seen them.Randy- how common is it for you to see them that far south?
Our little valley that once had 43 dairy farms and now doesn't have any dairy farms has turned into suburbia.
"Ranchettes".
Everybody has lights all over. They are super bright & just shine everywhere, including up into what used to be a dark sky. So this is the first time I've seen really good bright, northern lights here in twenty years.
I'd bet money on that being correct.Anybody that has used these sensors off of Amazonan, c they tell me what the wiring schematic is for the 3 wires?
I've had green be the ground in this harness. I've had green be the sensor output wire for this harness. So I don't want to mix them up.
I had a PM on this and we both think:
Blk is grd
Red is +5v
Green is sensor output
This is what I'm running with unless somebody can tell me other wise???
Yup, throttle stop screw. Have bumped it out enough to idle at 800, maybe I should go 900 or more till it will at least idle decent b4 it's warmed up. Reset the tps each time.I didn't see an answer about a throttle stop screw. You do have one, right? Have you tried doing anything with it? If you're on open loop, that throttle stop screw is key.
Agreed, problem with Term X is it has ONE O2 sensor.But before doing that, a couple questions… it idles at 800 RPM but just #1 isn't running?
I know you've written this stuff but it's all over the place and I know you've made changes. And now the AFR if lean and it was rich?
Agree, I'm such a novice but starting to learn.think you need to make it rich again and go from there. You don't even know its accurate without your tune being right. Your wife band will read unburned dual as super rich. You gotta know how much fuel makes it happy above idle before you know how much fuel it wants at idle.
Ignore all the readings and just use your man sense to make it happy. Add fuel and see how it reacts. Add air and see. Change timing and
I don't believe you need more than 1 wideband. I have the choice of 1 or 2 and I run 1. You could always get another sensor and just swap the connector or get a second controller as well and run one to a gauge and compare the two but I think you're just gonna drive yourself crazy trying to understand the differences. Should be close enough.Yup, throttle stop screw. Have bumped it out enough to idle at 800, maybe I should go 900 or more till it will at least idle decent b4 it's warmed up. Reset the tps each time.

Term X O2 sensor is on DS, cyl 5-8.
My old wide band is PS, cyl 1-4.
I feel it needs a bunch of fuel to drop #2 & #3 down around 600deg or lower and also for #7 wich like #2&3 is super hot.
Rest are fair
Agree, I'm such a novice but starting to learn.
I just removed the TB again to dbl check the gasket sealing btw it & the intake since it's 3 out of 4 of the middle cyl that are excessively hot.
It's fine.
I've thought of that too TS. If I didn't have any hot cyl on the TermX side I would do that but I have one there also.What would happen if you swapped the O2 sensor locations?
