You will have to set the values, cliick program.

I have tried this (LC1 analog output 1 --> Microtech), but my programming with the LM-Programmer SW was not perfect, because I found out that the values are only displayed in two digits. (9,0 - 10,0 – 11,0 – 12,0 – 13,0 and so on)

What values have you programmed at the LC1 output 1 to simulate a narrow band, so that we can read right wideband values on the Microtech.

Unforttunatley i have not beend able to find the right points to date to simulate the narrow band...it gets frustrating doiing the trial error..especially when the it starts to act up and need to be recalibrated and i have to under the car and take out the sensor and do the reset. I tried this about 3 occassions pissed and left it. I may try it again today. It would really make life easier with tunning so i lift its worth the effort if it works out. had an idea in the latter part of my last attempt session which i am gonna explore further next time.

The approach I am gonna try is this..the Lmprogeammer has an option in the advanced section that allows you to set the voltage that the lc-1 sends to the output during warm up...so i would use this by trial and error setting different voltages and see what ecu reads out at the different voltages and use that to find the extremes of the scale in programmer and test it with the engine running to see how the in car gauge and ecu compare.

My ECU gives me readings to one decimal place with more variance than just .0. Looking at a log i have here of my ecu i am seeing the following figures: 10.6, 11.1, 13.6, 14.0, 14.7, 11.8, 11.9, 12.7, 12.0, 10.8,11.3,11.5,11.8,16.0,16.3. Although there aren't right they seem to show variance hence the hope of being able to give accurate readings.

I am in my car collecting data right now.. and this are looking promising so far.
Stuff far.
1) I only seem able to log between 10.6 and 14.7 on the mt ecu..which is strange..because i have seen it go up to as far 19afr before. But between these points where you wanna be on boost anyway so thata good enough for now
2) So far i have gotten an almost perfect co-relationship for 11.1-12.5 afr so far.

I have not driven the car..just doing this from my car parked in my driveway and turning on a revving. I am just sitting here with the car off watching the counters go up while the gas slowly escapes the exhaust...gone to be here a while....anybody got a snicker??? :D..will report when finished

BluRR 03-22-09 10:22 PM

I think I got it..at least for the 11.0 to 14.0 afr range. Here we go.

Go to your lmprogrammer ..analog 1 or 2 which ever you have connected to your ecu and use this setting

volt afr lambda
0.965 10.6 0.721
0.65 15.49 1.054

Thats what i used to get the following readings...the first column is the LC-1 reading and the second is the MT ecu handset readout.

Lc1 MT
11.1 11
11.3 11.1
11.4 11.4
11.5 11.4
11.6 11.5
11.7 11.6
11.8 11.7
11.9 11.8
12.0 11.9
12.3 12.4
12.4 12.5
12.5 12.5
12.6 12.7
12.7 12.5
12.9 12.9
13.0 13.0
13.1 13.1
13.2 13.2
13.5 13.5
13.6 13.6
13.7 13.7
13.8 14.0
13.9 14.4
14.0 14.5
14.1 14.7

NOTE: This is what work for me and my setup...it may vary for you. I have not driven the car to test it above below the 11.0 point, but i think its a start.

I would like you guys to try it and report back

mattmarrx3 03-23-09 02:44 AM

yep i think thats pretty close i ran a log of lc1 and a data from ecu have a look and see what you think

how do you up load it as it comes up with invaild file

BluRR 03-23-09 07:38 AM

i had just copy and paste them....I had done it up in excel and just copy and paste it here. I didnt take mine from a direct log per say..just read the values from the gauges and noted them over a loooonggg time..

Just take some time and enter them down here

KalliR 03-24-09 09:01 AM

I don’t know what’s happened at the moment with my LC-1.
The LM-Programmer doesn’t save the new values from BluRR list.

I’ll trie it tomorrow once again.

BluRR 03-24-09 06:08 PM

its funny..it will give error messages about the range..I had to just kind of juggle the numbers.. as in each cell.. because essentially you switch around the graph against stock setup.

BluRR 03-24-09 06:21 PM

and of course you only need to do either the afr or the voltage..the ecu converts it for you

That was not the problem.
After clicking the program button it seems to be saved the new data into the LC-1, but when I look at the LT-10s I saw that there was nothing changes.
So I looked back to LM-Programmer and see still the default values. :scratch: :icon_no2:

BluRR 03-24-09 10:13 PM

What i do is..make sure the lc1 is plugged into the laptop before turning on the lc-1.
Turn on the lc-1
open the lmprogammer
set the values and click program
close the lmprogrammer software
turn of the lc-1
wait a few secs..maybe 15-20..then turn it back on and the new program is there...try that

BluRR 03-31-09 07:58 PM

This thing doesnt seem to be working properly..its not consistent..it does it own thing when it feels like :(

felix_is_alive 02-11-12 04:42 PM

ok , now i know this thread is old , but i still cant seem to find a newer one
is it possible to use the aem uego controller gauge ?, but use the output that simulates the ernst cell narrowband ?
