VEMS I5 Maps

[Carfreak]

I am trying to load the RS2 file in the first post with V3 16x14 High-boost profile and it is generating some warnings in audit log.

What am I doing wrong?

Do u have the right vemstune/megatune and firmware ?

someone have a file for gt3076 and 630cc deka ?

Ahh gothenburg.. Me too... PM me if you need backup

That´s right Watched uré car several times - love it!!
Thnx m8! Are u good at tuning vems ? I think I´ll let Jörgen tune my car if his good

IS this a plug n play box ? or is it just an ordinary one ? Be carefull wich input you choose for the fuel pump.. Where in Swe do you live ?

Ignition timing map is just completely wrong.
Even a car with a carb and a dizzy can run better timing

And you need to be sure it's triggering correctly and the timing you are running is really the timing you are running.
I would verify timing with a strobe light to be 100% sure.

Of course I don't know how important this is to do with Vems PnP...

Btw, my comment is not very constructive, because ignition timing is not something you can explain in 1 forum post. Take a book and read...

Thnx!

Yes that´s true A more fine tuned ignition will be made!

The timing is right, had to make a slight adjust on the dizzy.

Vems is using all 3 ignition sensors but still it could jump +-3deg sometimes!

I understand that, I´m upto reading the megamanual for megasquirt right now

Pump relais should be switched by VEMS output pin 15 for v3 (RTFM!:mischeif
Base schematics:

Please use a good quality fuse (>15A) between battery and relay, preferably close to battery.
As for wiring, a 044 can pull up to 15A in current so make sure to use decent connectors AND crimping tools to avoid smoldering relay sockets... wiring size 2,5mm² should be enough. (1,5mm² too small for my likings)

As for base timing to pass your MOT: finetune it on the spot while connected to the exhaust gas analyser if they let you. Make sure your lambda sensor is working and capable of holding 14.7 target before getting there...

Thnx m8! I have some difficulties explaining stuff on english but it was that pin out cable I was looking for to pull the relay!

[quattro84]

Understand what u mean!

I know about electircity and how to connect a relay and such!

Just wounder were I can take the signal from to click the relay (Haven´t taken a look at the stock loom yet).

Okey


What do u think about this tune ?

What setup you use and boost used?

[Carfreak]

You will need to do that at start anyway. And when tuning, also when tuning the knock detection, you will need to use your ears.

Okey

No!

Personally, I've never seen it work.
Some people have said they have gotten it to work. All the hardware is there so I guess it is a question of setup.
I personally think it would take me more than a day to get it to work satisfactory, and I would need lots of equipment to do so. And even then it would be worse than on stock ECU (the stock ECU contains per-cylinder noise maps, only way they did that was with in-cylinder pressure transducers).

ah okey.. So it´s much better to use an probe and amp with headphones to detecht knocking ?!

[prj]

To be safe at low boost and up to 3000rpm, could I set the ign timing to a stuck value ?

No!

Does the knock feature work satisfying on vems or is it still problems with that ?

It is not that simple. Also, ignition timing needs to be correct as well.

okey.. I understand that It takes tons of reading and many years of tuning to be a pro like u and many others.

But if I start with a basemap with correct req fuel and dwell for the coils and go with the target to lambda option - is there any possibility to reach a VE near lambda 1 as possible ? (This with wg spring load(1bar) and safe ign timing)

To be safe at low boost and up to 3000rpm, could I set the ign timing to a stuck value ?

As I sayed, just want the car driveable (Up to 3000rpm) with good lambda and CO values for the MOT..
