How to set up RoadRunner with LC-2 Serial Widband

[Ponrov]

Hi I`m new to the forum and new to Efi tuning,are there anyone who has the opportunity to help setup/program V7.5 Scan and tune together with Roadrunner and LC-2 Serial Wideband.
The firs ting I going to try to tune is the B0101 and B5001

1. what pid`s to use in

LS1_Link
;Main VE Table
B0101.ROW=SAE.RPM
B0101.COL=SAE.MAP
B0101.RRR=CALC.?,

2. what Pid to use in the PID`s , I have made this one below
[ATTACH]22540

3. Have used the calc_pids.txt from Calc.VET: correcting MAF and calculating VE (in single log)

4. how to create and use the filter in the RoadRunner menu.

5.have tried to log but did not get the same values in RoadRunner B01001 that were in VET Maps ,

6.got no values in the RoadRunner box that shows Data for RTACS

The car I'm going to tune is a 72 firebird with 70mod 400 Pontiac Ram Air 3 with 4l80e which I've converted to be controlled by 0411 PCM, has been helped by Lextech to put together the progam.

If you're correcting B0101 VE table, then you would use a BEN pid (same as you would with a non-RR PCM)...

Is your wideband connected to FSV2 using analog connection (signal and ground) or serial comms...?

Which BEN pid are you attempting to use...?

The B0101.RRR pid is expecting a BEN pid, i.e. a correction, not an absolute value.


( BTW: you have to do ise V7, not V8, to run the RR )

Hi Joecar

Thank you for your feedback

LC-2 is connected with serial connection to V2

LS1_Link
;Main VE Table
B0101.ROW=SAE.RPM
B0101.COL=SAE.MAP
B0101.RRR=CALC.BEN1


Have contact between V7 and RoadRunner, but do not get the same values in the V7Scan Vet Map as in RoadRunner B0101 , and the values in RTACS increases quickly to max limit .

Has taken out the LC-2 wideband sensor and calibrate it, has also installed an additional Autometer wideband lambda to compare the values and test again. (have to wait for some nice weather outside).

I'll dig out my RR and try what you did...

[Ponrov]

Has now checked the AFR after calibrating LC-2 and mounted Autometer wideband , AFR signal shows the same on both gauge.

Has now checked the AFR after calibrating LC-2 and mounted Autometer wideband , AFR signal shows the same on both gauge.It's good that you got AFR matching on both (but did you consider that each uses different stoich AFR)... can you get them to show in Lambda instead...?

[Ponrov]

Both are analogue instruments ,where one is connected to LC-2, it shows the same as shown in the dashboard in Scan v7.5 in AFR value.

That it shows different values in Scan V7.5 CALC.VET map and in Tune V7.5 table B0101 with Roadrunner, must be a calculation between those who are wrong ?

[joecar]

No matter... Calc.VET uses Lambda * EQR (i.e. is independent of stoich AFR).

Are you running gasoline with 0% alcohol (i.e. E0)...?

[Ponrov]

The fuel is 98 octane, without ethanol.

Br PonrovPost some screenshots so I can see what is happening...

[Ponrov]

post someone after work today,

[Ponrov]

have only had the engine running have not driven it, tried on the last log (the picture are from) to switched from CALC.BEN1 to CALC.WO2BEN (same result).

Is your tune scaled for MAF or IFR...?

What injectors do you have...?

[Ponrov]

Is your tune scaled for MAF or IFR...? I dont know, where can i check it .
MAF is 75 mm with std GM data
22571

The injectors I use is ID850 Injector Dynamics , have used the data from link below with 58 psi fuel pressure
