Well, I finally got my car running right. My issue after getting VEMS installed and running around doing the autotune for 60 ish miles was that I was fouling plugs and the car didn't seem to pull as hard as it used to with the Vitesse piggyback (my car also has a vitesse stage 3 turbo). Since I don't know how to tune and didn't want to blow something up. I took it to a dyno tuner.
Here's the first dyno pull using the basemap that shipped with it + 60 miles of autotune:
Not too impressive.
However, after a dozen or so pulls, adjusting the fuel and ignition curves, this is what I ended up with:
I am very happy with these numbers and the car pulls harder than it ever has. In fact, the car has never run this good - idle is now dialed in and rock solid and performance off boost is much better than it ever was before I put in VEMS.
So - I plan to just enjoy the car for the fall then this winter put in the wasted spark system. I'd also like to get A/C system working. Does anyone have settings/instructions for these two things?
Thanks.
What are your others mods on your car? Do you min sharing your configuration file to compare?
It was pre existing and was hoping WS might solve it but no such luck
Unfortunate you are still having the same problem. I've read online a few people experiencing a hard reset of the vems ecu during cranking. Primarily a voltage drop issue and that vems is sensitive to voltage drops. Basically the solution was to put a capacitor in parallel with vems ecu to compensate for the voltage drop.

That makes sense. I might try googling and see if I can find out what someone who solved it did. Cheers
Not so much of a change , did that little make almost 100hp?
At 200kpa line you have raised the ignition by 0,5-1 degree only and at the lower 160 and 130 kpa lines you have lowered the ignition a little ?
Nothing changed at all below 100kpa line.
You skipped the 250kpa line i think
What fuel?
Any more mods to the engine?
Do you have a max egt reading?
93, stock internals, 3" test-pipe/exhaust, tial wg, manual mbc, #80 siemens injectors. I have an EGT sensor hooked up but I haven't logged anything...I could do that at some point.
