Vems firmware 1.1.81 has release status

[GazzaG60]

it does.

i just run mine hit and hold. im a great believer in simplicity

[A80Avant]

well it is simple because the controller does all the job!! in vems, once you put the stuff there, it should (ought to) do the same. We'll see!

[GazzaG60]

have you gone to the new fw yet vas.

im now back in the persuit of better tune on 1.1.23. you lot will be the death of me i tell you. i was happy not tuning but now i got a laptop on charge all the time.

im not entirely happy with some pf the cells. i drove to halifax on saturday and i found a few sites where the egt went up. they need some work now. also the startup i have trimmed too much and it mumbles on a cold start now like i do when i have to get up and go to work.

maybe later tonight i will fix the issues.

[A80Avant]

are you coming to ADI Gary? i will have the laptop with me and we can play around a bit if you like.

im getting an ECU for a friend so Marc is setting it up for 1.1.81 with features that i need, so i can pass on my ECU (friend in greece not really that interested to mods, just likes a good working map, and has same setup with my 3071R setup, so it will be easy to set it up for him. Getting the 1.8T sensor fitted late october and hope by that time to have the ecu at my hands. we shall see!

so far 1.1.27 and working nicely. a few things here and there, but overall no probs

just finished fitting the NTC pullup resistor and setting the pullup for your adjustable boost trimpot. next is firmware update and road testing. I'll need to order the right trimpot but I'll test it for now using inline resistors to verify the functionality.

[Billman]

Marc can you post some pics on what need to be modified for speed sensor and this poti thing Vas wants? It would be great. I am going to remove the resistor also in the next days to use 1.8 temp sensor.

[A80Avant]

dont forget to check the timing difference from my setting to yours as well as from 1.1.27 to 1.1.81. In the mean time i will try and get hold of a timing gun. As soon as it leaves the US, i will make arrangements. (that is called triple checking!)

or just buy a boost controller and be done with it once and for all. no need to worry about vems firmware changes to boost or any of of that.

to be honest vas it sounds like poor solenoid control. maybe something you cant really do much about.

i get classic big turbo boost more gas more boost. so 1st and second can produce upto 0.3 bar less than 4,5,6

not really vems boost control in later firmwares is very good and has safety features an aftermarket does not have like being able to reduce boost on high egt or MAT temps.

I have both and I won't be going back to the separate controller, why am I having 2 pieces of equipment when one will do the job plus i can map switch and change boosting to use gear settings. full boost all the time is not good around town

[Jamo]

yes, im doing that on mine as well, definitelly want to use gear depended boost. Also i will be adding the anytrim feature for boost purposes with a potentiometer, which hopefully make boost control easier (according to mattias that is over at vemsforum).

Is there actually hardware to be installed on an ecu to see speed? I thought that by connecting the blue/white cable from the dash, same used for cruisecontrol the ecu would be able to read speed after setting the parameters on the software.

depends on your ecu, brand new ecus have safety hardware for the wheel speed input so it doesn't blow the ecu up.

[A80Avant]

how can that happen? blow up the ecu i mean? isnt a speed signal Volt depended?

Sensitive pin

PS2 clock input is a direct CPU pin. It is very sensitive. Either static electricity or 12V will damage the main processor immediately.

[A80Avant]

i see

so after the utilisation of this, ECU is ok then?

[GazzaG60]

full boost around town is great jamo. be a man

not going to ADI vas. never do. im not a big enough audi lover tbh to drive all that way. i think adi would be a good place to map top end timing to try and keep the temps down. at present i have no oil cooler so its a no-no for me.

also of recent i have been blowing the small hose from the reverse inlet to the isv off. the top one from tge metal tube. its peeing me off as its well tight. it happened last night up a steep hill 65 ish second gear 1.8 bar. blew off at 6500 ish. may mates still said "thats the fastest ive got to the top of there ever" i wanted to take third and motor on really.

its all about fused circuits. ISV used to be one of the easierst ways to blow a vw ecu. it was an unfused circuit.

[Jamo]

Well today I downgraded back to 1.1.74, the car didn't run as smoothly through acceleration on 1.1.81

I will upgrade when I have more time to play and a non looming deadline

[A80Avant]

was it on cruise or on boost that you noticed that?
