I had a brief look in the terminal program, Typed "Man,mlp01,mll" as you directed, the info that was displayed was;

RPM:0000 W00SFFI00 
99 -00 c0000 i0000 
clt:-40C  adv:+10   
0000 iac:000 135   

If i clicked on the "graph" tab There was also a small graph similar to dnb's but shorter,

but i didn't know how to copy it.

That's a good start.

If you type mll and keep hitting return as you crank the engine you should see a load of those info blocks come up.

I posted a VEMS fresh from a running RB25 and the test harness I made up to dnb today, it should hit his doorstep tomorrow morning and we'll get this thing sorted soon as we can.

I'll make sure I do the tests ASAP Rob.

BTW there's a command that does an automatic mll every 0.1 seconds.  I find it very useful, although I can't remember what it is...

This would be usefull as hitting return didnt work, i physically had to type "mll" repeatedly (while cranking), and got this;

I just checked the wiki trigger log page and it says:
"Continuous sending of LCD data: mdk01 every 01 second: mdf01"

The number after W shows trigger errors - which shows 0, I'm waiting on confirmation of what S and I are

W00 SFF IE1  -> W 00, S 255, I 225
W00 SB1 IDD  -> W 00, S 177, I 221
W00 S7F IDB  -> W 00, S 127, I 219
W00 S80 ID9  -> W 00, S 128, I 217

After some valuable help from Rob and Dave (dnb) and a test VEMS+Harness,
I have managed to finish the trigger setting and the other calibrations,
So it was now time to connect everything and turn it over;

Hooray she fired up first time!!!!!

its very rough but definately firing on all 4 and will rev easily! Im really chuffed!

so now for the fun bit- tuning and mapping ;D

Thanks guys for all your help!

Excellent news.

If you're up for some experimentation you might like to try something that I was helping someone with yesterday with regards to start-up fuelling.

First we work out the req_fuel for your setup:

req_fuel = 6.49 * (D / N / I)
D engine displacement (cc)
N number of injectors (eg. 4 for a 4 cyl port injection)
I injector flowrate (cc/min)

Then in priming cranking afterstart for Cold cranking PW we use req_fuel x 3
and for Warm cranking PW use req_fuel x 0.7

And that seems to fire up a couple of cars quite nicely.

Ok rob i'll try this, its wildly overfuelling at the mo but i wont be able to get on it til later in the week, im working lates.

By the way, with the new VEMS both the coolant sensors are over reading by about 15degrees (with original VEMS they were pretty well spot on) is there a simple offset i need to change?

We'll need to do a tempsensor_upload.bat to get the correct calibration sorted out.
I'll bundle up the software and write-up some notes on how to do this.

[s14nismo]

Cool ;)

Thanks Rob.

glad its all up and running hope to have mine running soon too  ;D

okay download this:
http://www.vems.co.uk/VEMSTech/VemsMT1.1.18Good.zip

And unzip it to somewhere useful.
You can use the instructions here.

By default these batchfiles use com1, this can be changed by editing the files and changing the -c com1 entry to the correct com port.

Sorry, Excuse my ignorance but The "command line in the VEMS root directory" is that the lower window in the terminal program? ???

No problem, its the command window in Windows terms, I'm showing my age (MS-DOS) and my geek credentials (UNIX) with talk of command lines...

I've modified a file to make this simple, download:
http://www.vems.co.uk/VEMSTech/tempsensor_upload2252.bat
Copy this into the top VEMS folder that contains all the other batch files like upload-firmware.bat
That should upload the correct sensor configuration

Oh i see!  :D

I found a handy tool (for XP) to quickly open command windows on a file (it just adds the option in the context menu options);
