Wide Band Logging today :)
 

Hey all, I managed to pull a third gear run tonight and happened to log it.


I'm attatching the xls file for you guys to check out.


It looks like i'm running hardcore rich in a lot of areas.


Log File

Yeah thats pretty rich. So fun tuning when you can just take a whole mil sec off and the car still is rich

Yeah, interstingly enough I was feeling a big pull where the log shows the AFRs going below 10 :eek:

I saw that, take some of that fuel off the bottom and put it at the top :bigthumb:

Oh yeah I forgot to post that this is with the blower OFF. Obviously when I have the blower back ON i'll have the 2/3BAR map sensor logging on the third User input for the TE.

what are you using as wideband? how much did it run you???

correct me if I am wrong but isn't stoichiometric balance 14:1

and you ran a 15.48 @2711 RPMS? isn't that supposed to mean super lean?:confused:

Tech Edge's 2B0 unit. I don't like to think about how much it cost me :)

Stoich IIRC is 14.7:1 Take a look at the TPS% at 2711rpms its something like 13%

recommend any widebands with logging that doesn't cost an arm and a leg or a testicle?

There aren't any.

damn................fine........what is the cheapest one you all know of right now?

the innovate LM1 aint *that* bad as far as price.

kevin.

so this is all I would need to be able to tune my car and avoid having to dynotune for 800+ bux?

Wankel7 bought a 2A0 that is a DIY kit, which you "build" you save around 100 USD by ordering that.

The 2B0 is not available in a DIY kit so I picked it up for around 375AUD which is something like 290 USD

Tech Edge units are really the best value I could find for what I wanted.

I built my own display(which I think I messed up, yey)
I built the sensor cable(flawless)
I picked up the sensor from the state of Washington! for about half the price of buying it from Tech Edge(48USD shipped)


So the run-down is:

283 -Main unit
60 -Display DIY kit
19 -2.6M Cable Kit
7 -Sensor Plug

369 USD before shipping & lacking the sensor.

417 USD with the sensor(shipped) Plus 26 USD for s/h from austrailia

443 Shipped total

But I am having trouble with the DIY display which I may have burnt the voltage regulator on. :( But its not needed for anything other than being a physical display in your car....










I'd say check out the TE stuff, its really nice stuff. If you're good with electronics/soldering you can save a lot of money by building your unit/display/sensor cable.

damn........that's a wad of cash!

lm1 is nice but sucks because everything is an add on with that bastard. Like the you can't log rpm until you get the auxilery port blah blah blah but some good ones to get are the tech edge and I've got the zeitronix witch really wasn't that bad. you can get everything but the readout for like 279 and just log with your laptop. I don't even use the readout anyways.

Considering what the Innovative stuff looks like, I dont mind that I payed 100 dollars more.

Did I mention I can log 3 two wire EGT units, 2 normal inputs and 1 Differential Input. I've got the nicest wb in town, not even the dyno's have that :p:

looks like the zeitronix is gonna work........

It still sucks compared to my FJO.
I can log each separate rotor's AFR separately, with two separate oxygen sensors. :P

Plus, you're fat.

LOL nice, but at 118lbs i'm a featherlight ;)

i think he meant PHAT....Pretty, Hot, And Tempting.......:cuddle:

Oh no!

Teh canadian lub :scratch:

Well i've got a scholarship check to go pick up, time for teh tunning :)

I've added the setting on the AFC at the time of the log.

Its the Hi Throttle map.


The fuel setup is:

550 primaries
720 secondaries
TII pump
N/a rails & FPR

Can you use that practically on a rotary? Maybe with long header tubes on a N/A. With a turbo application the sensors would get to hot to use.

Since I have true duals it would work perfect for me. As it stands I have three O2 sensor bungs on my exhaust: Header(stock narrow band), and one on each pipe about 4' down the line(for heat issues to be minimized).

Sure can.

NTK sensors and heat sinks. I'm yet to get a sensor overheat message.

I don't use heatsinks and have yet to have a NTK go bad. I even bought a new NTK to compare with the one that's been in there and there is no difference. It's the OTHER sensors that have heat related problems. Just an opinion. Take it or leave it. Narrow bands suck. Sorry, couldn't resist saying that.

While not real keen on bright shiney gauges, it seems to me you'd want a display to look at out of the corner of your eye at least, when checking out some change you've made in the engine. At least you can back off right away if you see some 14's, but if you data log on a computer, it SEEMS you'd only be able to look at the afr after the fact (unless someone else is staring at the computer).

The heat problems just cause errouneous readings for wankel7's NTK. This isn't a "oh i think i'll have problems" this is a "I've seen heatsoak issues affect NTK sensors" problem. I have a Bosch LSU 4.2 Sensor myself but I doubt i'll have problems with it.

What kind of heat sinks do you use? is it a sink to pull heat away from the sensor body(above the threads),or is something like the innovative one were the sensor threads into the heat sink with a fairly small hole on the probe end.I didn't figure you were using the bosch LSU 4 sensors...cheers

I made my own heat sinks with some scrap sheet aluminum and the ol 'tig. They contact the sensor body to pull heat away from the sensor, but attach via a hole at the bottom of the sensor, that the sensor threads through. Took me about two hours to make both of them.

I don't like the bosch sensors. They're cheap, not as accurate, and in my experience, don'tlast near as long. That's why they are 1/4 the price.

I'm just now working on some new logs that I got from the night at the drag strip last night.

I was able to start bringing the fuel curve back from the brink but I didn't really feel too much of a difference in the car's pull.


Btw- does anyone know of a place that has(for download) the old win98 or win95 excel? I could sure use it to edit files on my laptop rather than having to transport all the files over each time I log to clean them up.

When I was tuning my car, I did both. First I would tune the car by 'eye', using the WB display, as my friend drove the car how I wanted. That ensures that you catch any problem areas right away. That works well for a pretty good tune.

But, for the final tuning, to get the car really dialed in, datalogging is the way to go. Helps with correction maps, and also helps with those tricky map points that are more difficult to maintain on the street.

Here is a datalog of mine (tuned a little rich for Scathcart's liking, I know :bigthumb: )

EVIL what wideband unit are you using ??
