So today I finally tried the speed correction on my car, which is Mazda 3 BM 2015.
Right now I have 225/40 R18 tires, and when I'm driving at 50 kmph, GPS is showing ~47 kmph. When driving at 100 kmph, GPS is showing ~95 kmph.

I've made following changes in the file:
View attachment 289013

After Writing the changes, I got following DTC errors:
View attachment 289012

I've performed SBS/MRCC module initialization/relearn from Central Configuration. It fixed the DTCs.

Tested the speed - but noticed no changes. It was still different from the GPS at approximately the same value as before changes.

Before:

720G4G11CF10080FFB8

Has anyone managed to make it work using the Excel file?

I'm noy sure why you want to have exact measurment

I'm aware of a difference either on my motorbikre or car - it is always approx 7% of a difference. I like to have it. I'm talking about speed cameras here

 

[bonjoey]

I will try the spedo change when its not -40c outside. And will update any results

@SergSlim I'm still messing with my IC section - is the circled part of the file correct for my car?

I think i got it but im confused where to get the general checksum on 720 04 01 ?

I have no idea,

 

[lygi]

ok I went through every possible combination and looks like I will use black tape over the Amber-A to not see it.

1101 (LAS w/o HBC) doesn't kill HBC as I still see it in the Lighting menu. At least I tried ;-) Maybe one day we will find a working solution

Btw - should I see Both LDWS and LAS options in the menu? Or LAS includes LDWS so only LAS should be visible in the Safety tab? When I was playing with combinations sometimes I saw LDWS and sometimes LAS in the Safety tab

Just install the proper wiring harness adapter so the LEDs are configured properly and the lights can work without generating error messages.....

I didn’t do anything with my lights which are Halogens from the factory (only with LED bulbs but they don’t throw any errors)

lights are working correctly I didn’t test HBC as I don’t have any dark roads anywhere close by

DLR HB and LB with H11 and H15 in manual and auto mode - everything is spot on. Amber-A what I’ve read is a well known issue - only one thing I don’t understand is why I can’t disable HBC system and keep LAS and LDWS

 

[lygi]

Amber-A problem fixed with black lx tape.
I took IC out of my car - and put a piece of black PVC tape between HBC “window” and Green/Orange LED - blocking the light. Now amber-A is no more visible. Pretty ugly solution. It looks stupid but if it works it’s not stupid

LDWS is a subsystem of LAS, so to say, or vice versa.
So when you have LAS activated, you should see only it in the Safety menu. However, LDWS should be present INSIDE of the LAS submenu as an option with a checkmark. I don't remember how exactly it is called in that menu, though.

it is exactly what it looks like! Thx for confirmation

So i did couple of test and it works.
I followed the calculations and also using the excel to find the B5 checksum for 720 04 10 because i have a new B1
I dont have to change anything on 720 04 09 but if your setup needs to have different B4 then i guess you have to.
calculate the new general checksum for 720 04 01
then using forscan, i did put everything manually and not the whole 720 04 block
I also put the new B5 checksum to 720 04 01 from the excel but forscan changed it to different one.
Got some warnings about rf keyless something b4 i wrote it but everything went smooth, no errors or cel, and the speedo is now the same as gps speed.

right after some play with IC module my fuel level gauge started working in a VERY weird way. it shows a reversed value - I mean when it was full it was showing empty - and while I was driving fuel level slownly went... UP, up to approx 10% of my tank after 500 miles trip

I checked PID for fuel level and I restored my original IC config - PID shows 11% (which is correct) but the gauge shows empty. should I refill to full to reset the gauge or reset the IC module? Or is there any other way to have a correct reading?

 

[lygi]

After refuelling everything back to normal but looks like the area I asked you before @SergSlim is responsible for this mess

 

[Jeliran]

Hi Maybe he will tell you how to beat in the factory condition so that my Mazda Cx5 car becomes equipped with the installation of a drive in the trunk instead of the usual one. Installed the original from the donor Wires, block, button, shock absorbers Error plg_mz u2300:56-0a is now on Central configuration Invalid or incompatible configuration

@Jeliran many Asbuild functions are unknown. Ask seller the VIN number from donor car, do an AsbuildSearch and start comparing.

hi i have a question about "disable i-eloop" at 4th block how to disable it.thank you and
best regards

 

[craz]

Find @SergSlim post and at the bottom of his signature there's a link to download his Excel file, enter your asBuild in IC line 720-4-25 B2 disables i-eloop, watch Serge videos in Youtube.

 

[DanceM]

Tested the speed - but noticed no changes. It was still different from the GPS at approximately the same value as before changes.

I tried values from the spreadsheet on MX-5 2019 and it did not work - I have the exact difference in the speed as it was before. No changes.

PS: I also check the calculations in the spreadsheet and all seems to be correct.

PS2: I check AsBuilt data I have from three MX5s (2016/2019/2020) and all of them have the same value in B4B1 = 0700. And when I tried to put some weird values into B4 I immediately got "vehicle malfunction" and speedometer & RPM gauge turned off completely.

Please forgive my ignorance but what is this? Code dump from a ECM firmware? Or a readout from a ECM? Always curious about how a engine computer thinks.
