Vems firmware 1.1.81 has release status

[Jamo]

After 2 hours of driving still crappy acc. Somehow when accelerating it goes rich after 1.5 or so seconds it goes super stays like this for approximate 2-3 seconds and then goes nice again. Can it be that 1.1.81 sucks?

Anyone fancy sharing a 1.1.74 map W/O timing and VE table???

I've found the problem anyway, I've decided to be helpful despite the other post

Its the increase fuel over egt setting. no matter what your egt reading it adds fuel as if the egt setting is high.

Just confirmed in your config billman you have it set at 21.4 %

change that setting to 0 and it will not be rich, however I still had acceleration issues

[Billman]

Is there a problem with this increase fuel over egt setting? I will try this also out.

[Jamo]

I found if I had a value added it would add fuel, I could replicate every time

[A80Avant]

so does that mean that this feature does not work? it adds fuel all the time?? Or am i getting this wrong?

[Jamo]

That's exactly what was happening to me, billman can you confirm on yours.

it's easy to see, on the main screen change one of the gauges to lambda target if it's not already on there and you can see the ecu targeting a rich value.

remove the value from the option and set it to 0 lambda target back to normal.

i am going to try it out tomorrow.

I´ve made a S2 thats almost standard ( 5-600cc injectors@4bar. Turbo, IntakeManifold and Exhaustmanifold from rs2) that runs really well.

I can post a config from it tomorrow, if you open any of AccelerationE windows and just drop the config into the window it will just update that settings.

Its probably a good start.

I'd be interested to see the Acc E settings

for one, on the 1.1.81 that i will get i have used excactly the same accel.enrichment settings that i use on 1.1.27. I am even considering deleting the rpm vs amount to begin with,and definitelly the injector angle. This way i have less to worry about when im trying to get the car working for the first time. All thanks to marc of course. Once it is here and i have made it work nicely, i will post the config in the next few weeks.

Here´s the config I was talking about:

Cheers Erikk I used you acc enrich settings on the way to ADI and they seem to work a charm.

Can I ask you about your boost setup in the config? could you explain what you have done.

[Erikk]

I'm glad you liked it.

First, I have boost actuator off below 110kpa so it doesnt click at idle or when your engine is shutoff but ignitionkey is on.

I only used RefDC x RPM and raised the boost over 5500rpm so it gets a very sporty feeling.

[A80Avant]

Hi Erikk, thanks for sharing.

what N75 valve do you use, and also with those DC values, what boost do you get?

[Erikk]

I dont know which boost valve this client is using, i guess it was the standardvalve from the 3b.


I think it was like 1,4bar up to 5500rpm and then raises to 1,7bar, every engine is different on this point.

It runs on Gasoline @ 93% InjectorDC.
