Hi

My first post on this forum.

Sounds greate that you are planning to implement the functionality of increase of RefDC on AC input, l'm just curious of when you plan to do this?

Regards
Hans

Hello Hans,

Already implemented and tested, should be available on dev server later tonight, take care: experimental, only for testing.

Best regards, Dave

anyway, I have noticed one thing, for bmw s54, vanos +itb + turbo, when using alpha-n + boost compensation cam position table can be defined only by tps

Hello S6onVems,

Idle RefDC increase on AC input has been requested before and we will implement it as extension of the idle control function, the anytrim addition (2 extra channels) / higher than 510kPa in all kPa axises and config variables was quite intrusive, this change should be quite simple.

Best regards, Dave

Sweet!

This is probably not the correct thread for this, but you're here so I'm asking: how about allowing negative enrichment values for TPS-based enrichment? It is clear that the dTPS is calculated even when it is negative, as it shows up on logs that way. However you cannot enter anything below 0 in the dTPS enrichment curve. It would be neat if there could be a couple more points in the curve to allow for a short enlean event after a throttle lift. Right now watching Lambda it goes rich right after you let up on the throttle, unless you let off all the way and a fuelcut event starts. It almost certainly is just clearing the extra fuel from the ports, but it would be handy to be able to compensate for that. Of course this is another possibility for people to make mistakes so it might need a config warning! (Other idea: 'idle integral disabled above x wheelspeed' instead of just when car is stopped. I've been thinking about these for a while...)

Thank you.

Correct cam target tables use the same y-axis as VE table.

yes, but when fuel map is based on tps, even with boost correction maximum value is 100 in cam table =100%tps

I tried to install the new Firmware 1.2.32 but Firmware Web Tool in my VEMSTune only shows up to Version 1.2.31 available?

I downloaded the file by Hand (1.2.32.zip) but VEMS Firmware Wizard only shows 1.2.31

Please follow directions posted here: http://www.vemssupport.com/forum/index.php/topic,2410.msg23276.htm (or wait until we make the 1.2.32 available for the general public, usually a few weeks after development in that version has stopped),

We can think about making this selectable in the future.

Thanks...  I forgot to use the (Re)Install Firmware button...

UPDATE

Firmware installed successfully...  now I have to test a lot  :D

this one wants it ;)
Seems like a nice project, good stuff!

Best regards, Dave
it runs already, 750 hp 980nm @1.7 bar, intake needs some modifications, it should mane more power with same boost :) but it would be really nice to have bigger ignition table, it's really hard to map that type of cars with that small table, on this one i have to fit tps ignition + boost ignition, that's pretty hard if I want to run it lets say 2.5 bar :)
