I went out and did some tuning early this morning, then went to the track. All of my logs went just fine. Then I logged it when I went to the track. The AFRs recorded went crazy. Logged continuous 7.x then 14.x.. random afrs right in the middle of a string of somewhat stable values . I did change to race gas, and also I am now using a home made tail pipe setup. However the logging before the track was using the tail pipe setup aswell. Also looked down at the lm1 once and there was a error 08 I beleive... I will do some searching and readin on the LM1 instructions, but where do people prefer to mount the Wideband sensor. I have previously been using the bung in the test pipe. Here is the log...

 

How about this

 

I've seen that 08 timing error before when the O2 sensor has gone bad once from H2O once from debris on a new exhaust install.

 

3rd times a charm?

Brand new sensor, and nothing else has changed

 

Looks like you need 1 of these http://www.innovatemotorsports.com/x...cat=250&page=1

or 1 of these http://www.innovatemotorsports.com/x...cat=250&page=2

 

Oh and the numbers that seem to be somewhat normal I dont really beleive either.

 

Its plugged. And I dont beleive there to be any leaks. The home made piece I am using for a tail pipe clamp has been used with success many times. Although there isnt a venturi affect.. Its 1" ~ pipe with a bung welded in, and a tab welded to it, to put a hose clamp around it and the tip. I was abou to purchase the innovate product and my neighbor just happened to have this setup. He has used on several platforms. I cant honestly say I have seen him use it but he is a pretty **** dude.

 

Just weld a bung into your pipe in front of the cat and be done. Simple and cheap.

 

What did you log with?

the Innovate protocol is somewhat complex, and a weird status code (either an uncalibrated sensor or something else) will screw up the values if the logger your using doesn't take that into account.

If your not testing with logworks to verify its okay, then I would install a copy and test with it. Its possible you need to do a first-time free air calibration as documented in the install manual before the wideband functions properly.

 

Evoscan v.97 Sorry Malibu I would use mitsu logger but am I correct in assuming no LM1 support yet? I like both, but I payed my small donation for evoscan before I knew about mitsulogger. At any rate you guys both are awsome! I do have the Logworks software on my laptop, and I have opened it up once to verify it worked, but never logged it. Once I actually get time I want to look into the integration of ecuflash/LW.. But I know little of it, and havent found any magical link yet that says heres what you do... I did do the free air calibration last week whe I first used it. However im not very confident in it. After going thru the steps, at a point where it was suppose to say calibration needed, it did not say that. Also I pressed the cal. button when suppose to. The instructions says it would take x seconds. And I wasnt able to visual see that it was doing anything at all. I went a head and made some pulls with it. And it all seemed fine. Up till today Id didnt seem to do anything out of character. With acception of an erratic (by only a few tenths) afr here or there directly between 2 lines that were close. I attributed this to me being new to actually logging instead of watching the gauge.

Thank you for replying, but I think you will find if you re read post 1 there is already a bung in the test pipe. (also meaning there is no cat) I just wanted to try the tail pipe clamp since I bougth a portable unit, thinking that I will be using this on many different cars/types of cars.

 

I had this issue with my LC1. The grounds I used to the chassis (on the interior side of the firewall - which is where we used to ground them with the XEDE SMART setup and they worked great) were causing it to recalibrate when I started the car. The result of this was AFR ranging from 7.x to 24.x. I went direct to the neg terminal, did another free air calibration and all is well since.

 

I had problems with the grounding also. I ended up running the ground thru the firewall and onto the engine block. It helped.

 

First, as MJ points out, EvoScan does not parse the packets completely from the instrument. So weird values could just be an unparsed error code.

Second, make sure your free air calibrations are, in fact, free air. If you calibrate in trace exhaust gas, the instrument will give innaccurate readings. In fact, this is one of the few ways you can make the instruments read artificially rich.

Third, solid grounds at a common point (engine block is best). Remember, LC-1's and LM-1's take measurements about 250 times faster than a current-based wideband. On the one hand, you can see a single missfire as a spike, on the other, that speed makes the instrument more sensitive to noisy grounding.

Four, check for air leaks, particularly around the bung. Normally, this results in lean spikes, so it is low probability. But, like calibrating in exhaust gas, it is one of the few ways to make the instrument oscillate.

Fifth, you can call us. We're way past the 50,000 unit mark, and yet to charge for a repair. If there is, in fact, something wrong with your unit, we'll take care of it.

From the Innovate Website. Klaus is the man that designed the system.

"Hi,

If your sensor is showing error 8, it can mean one of the following things:

1. Sensor overheated
2. Sensor undercooled
3. Sensor broken
4. Heater calibration of the LC-1 not done correctly
5. Bad heater ground.

Number 1 and 2 happen only under certain circumstances, like WOT. Number 2 is often related to number 5.

Reason Number 4 and 5 are the most common reasons, number 3 the least common.

Regards,
Klaus
