Just checked all my old mappings (every change i give my mapping a new version number).
Can't find something meshed up like the 2 stroke etc.. Very strange...

i see that my MAP Compensation map is kicking in.
This settings have NOT changed since 2011

I also cannot hit the throttle, the engine stops directly due the lack of fuel..
WTF is happing :? :? :?

put the fuel map back as it was ie around 0.80, remove the map compensation.

ok, but why has the engine always started and was running good with this map..
I can't figure out what the change of an ECU can give this mess in my mapping..

i dont know, but the fuel map in those pics looks like it was done without map comp. so turn map comps off and see how it runs!

Well I think there was indeed a big problem with my previous ECU
Just been checking my log files..

Because of the S-Dash display of Marco (i'll contact you soon, still need to get those other units from you) i found out that the compensation map was working not as it should be..

My minimum injector Pulse Width is 0.9 - 1
With 1.2 Bar boost and full throttle 10,5

Damn this is very very very strange.
Never noticed this before :S

And like said. I was running these settings for more then 4 years now.
I only changed the last few months my fuel map in the high RPM part with 100% throttle.

Will change the fuel map tomorrow back to the 0,9 - 1 ms
and change the compensation to 0 to test..

Alex do you have an explanation for it?

Nope, I have no idea what's happened here.

At least you now know what's going on, and should be able to get up and running again soon.

@stevieturbo, :D :D :D good name, we where thinking about wildfire because she had flames out of the exhaust with a lenght of 1 meter. Christine could be her middle name because of these problems for 6 weeks :)

@alex, yeah indeed, need to do some dyno time now.
I'm afraid for the rest of the mapping now
